STUDIES IN THE GENUS HYLEPHILA BILLBERG, II. THE BOULLETI SPECIES GROUP
(HESPERIIDAE: HESPERIINAE)
C. Don MacNeill
Department of Entomology, California Academy of Sciences, Golden Gate Park, San Francisco, California 94118, USA
ABSTRACT. This is the second of three papers on the genus Hylephila Billberg (1820). The first paper introduced the genus and, emphasizing male and female genitalia, defined four species groups, two of which, the ignorans and the venusta groups, were treated in detail. The present treatment keys adults; illustrates aduJts, stigma pockets (male), and genitalia (male and female), and maps the known distribution of the species of the boulleti group, seven of which are described as new. Although specimens (especially females) are woefullly scant, their characters seem to suggest two subgroups with five known species each. Subgroup I has H. herrerai, new species, H. pseudoherrerai, new species, H. pallisteri, new species, H. blancasi, new species, and H. tentativa, new species. Subgroup II comprises H. shapiroi, new species, H. galera Evans, H. boulleti (Mabille), H. rossi, new species, and H. peruana Draudt. Examination of the male and female genitalia is generally necessary to be certain of the identity of a specimen, but wing patterns and some structural characters may permit a "good guess" once familiarity with these skippers is established. Ova of two species were obtained by dissection, and these are described briefly for the first time.
Additional key words: South America, oreal (of high mountain), altiplano, Andes, dashed Phulia pattern, genitalia (male and female), stigma pockets.
In a previous paper (MacNeill & Herrera 1999) on the genus Hylephila Billberg (1820), we introduced the genus, emphasized the importance of male and female genitalia, and reviewed earlier attempts to illustrate these. We recognized, defined, and provided a superficial key to four species groups. We mapped three of these groups which are principally Andean, and treated two of them, the ignorans group and the venusta group, in detail. We also discussed and figured Linka Una (Plotz 1883) owing to confusion about its relationship to some high altitude species of Hylephila, especially the boulleti group (Shapiro 1994:44, 45), which is treated here in detail. Techniques, methods, and materials—as well as terminology—used in that study also apply in the present paper. A third paper (MacNeill in prep.) will treat the remainder of the genus, the phyleus group.

The Boulleti Group
The ten species of the boulleti group all look very much alike superficially. It is usually necessary to dissect the genitalia to identify a specimen. These are small to medium-sized skippers (forewing length 8.5 mm-15 mm). The body is blackish, but the black tegu-lae are contrastingly and broadly edged with pale yellow or white. On both surfaces of the secondaries (Figs. 32-57) there is a well-defined ray in the cell (at least distally) and through spaces M1-M3. Bold black spots are characteristic on the ventral surface basally, postmedially, and marginally, where they appear to be defined or cut by white or pale veins. This gives the group an appearance when at rest that Shapiro (1985:8-10) has called "the dashed Phulia pattern"—a common pattern at rest shared by some high altitude pierids and hesperiids of oreal bogs and meadows, and this may well be, as Shapiro suggested, the result of convergence for crypsis at rest. He noted that these swift flying animals are remarkably difficult to find at rest, even when very abundant.
The species of this group occur in the high Andes from central and southern Peru, western Bolivia, and north-eastern Chile into northwestern Argentina and the pre-Andean Nevadas del Aconquija (the Sierras Pampeanas), just west of San Miguel de Tucuman, Ar-

gentina. All of the species in this group except one are known from Peru, and the exception almost certainly occurs there too.
Because they are found at high elevations where both the weather and access are often limiting, and because of their crypsis (see above), these species of Hylephila are not often collected and they remain rare in collections. I have seen more than five specimens of only two of the ten species and females of only five of these (three are single specimens), and I have seen only one male specimen of four of the ten species.
Evans (1955) treated three species of this group as two subspecies of H. boulleti, (Mabille 1906), H. b. boulleti and H. h. peruana Draudt (1923), and one new species, H. galera Evans. Seven additional species are described in this paper. Given the general paucity of material, I must admit to some hesitation regarding the possibly presumptive classification presented here for this group of Hylephila.
Based upon the male and female genitalia, the species of this group sort rather well into two subgroups. The males of the five species in the first subgroup tend to have the anterior half of the uncus rather rounded in dorsal view and the gnathos is massive and caudoventrally somewhat divergent from the uncus in lateral view (Figs. 12-18); two solitary female specimens lack a detectable sclerotized eighth sternite (Figs. 26, 27). The other subgroup of five species has males with the uncus more or less triangular in dorsal view, with minute lateral serrations caudally, the gnathos not as divergent ventrally from the uncus (Figs. 19-25), females have a distinctly sclerotized eighth sternite.

Etymology. With considerable pleasure 1 name this species for my good friend, the late Prof. Jose Valentin Herrera G., to whom
this paper is dedicated. Pepe Herrera devoted well over four decades to the collection and study of Chilean Lepidoptera. He was actively involved with this study of Hylephila and co-authored our first paper on this genus.
Diagnosis and discussion. This species is distinguished by its small size, lack of a stigma in the male, and the broadly darkened vannal area above. It differs from males of H. pseudoherrerai in its smaller size, darker wing markings, and in genitalic details of the uncus, pectines, and juxta. The female genitalia most resemble those of H. tentativa in the lack of a sclerotized eighth sternite, but the very short apophyses an-teriores, and weakly sclerotized, short ductus bursae differ from these structures in H. tentativa. The wing borders are not as broadly cut by fulvous along the veins as are those of H. tentativa. The species flies in February.

Fulvous rich to cold orange costad of discal cell merging with apical spots (but sullied basad), in discal cell (where divided by broad, blackish fuscous streak from base to end cell where connected broadly to elongate black spot between end cell and subterminal spots), and below cell in base of space Cul-Cu2, in subterminal spots and in postmedian band from spaces M3-Cul to Cu2-2A, where sullied, and in most of cell where also sullied. Fuscous border broad, only slightly cut by fulvous veins. Fringes brownish, at tornus sullied fulvous. Below costad, apically on veins, and distally on fringes, whitish. Hindwings above with fulvous somewhat restricted to a ray in distal half of cell through spaces M1-M3 to broad, fuscous border, in cell Cu2-2A from near base nearly or quite to margin, and narrowly as part of the postmedian macular band in spaces Cul-Cu2 and M3-Cul, and scarcely evident in space Rs-Ml; fuscous border broad, scarcely cut by fulvous veins. Fringes pale fulvous to vannally fulvous and apically fuscous. Below, extensively pale fulvous with contrasting white veins Sc to Cu2; black spots basally in costal cell, discal cell, and ray-like from base to margin in space 2A-3A and anal cell, postmedially near base of spaces Rs-Ml, M3-Cu], and Cul-Cu2, indistinctly and ray-like in Sc+Rl-Rs, marginally in spaces Rs-M 1, M3-Cul, and Cul-Cu2.

half depth of valva. Penis strongly curved dorsad anteriorly (or straight), its length exceeding length of capsule and subequal to twice length of valva; titillators sclerotically strapped to penis, slightly asymmetric, the left more robust than the right, thorn-like with its point (more or less) angled ninety degrees from its base, cor-nuti bidentate, slightly asymmetric. Juxta with ventrocaudal clefts about one-half length of juxta, the separated median floor nearly reaching caudal margin of juxta. Uncus in dorsal view greatly expanded and rounded cephalad, then abruptly emarginate caudad, or smoothly tapered, to pectines; caudal cleft distinctly exceeding pectines cephalad; pectines small, each half broader than long, not anteriorly rounded, the tines conspicuous, few; in lateral view somewhat arched.

Female. Unknown.
Type. Holotype d, PERU, Ayacucho, Reserva Nac[ional] de Pampas Galeras, 4000 m, 17-11-78, J. L. Venero (genitalic dissection # 6 3820-JH), in the Museo Nacional de Historia Natural, Peru (MUSM). Paratypes. 1 (5, same locality and collector as holotype, but 27-1-78, (genitalic dissection # 6 6311 -CDM); 1 6, same locality but date 21-IV-74 and G. Lamas, collector (genitalic dissection # 6 3736-JH). Paratypes will be placed in MUSM and CAS.
Etymology. This species, while small and without a male stigma, is not the same species as H. herrerai.
Diagnosis and discussion. The holotype has narrower wings and is more orange than one paratype. The latter is larger, paler, and looks very much like a female of H. houlleti, which I thought it was until I dissected it. The genitalia are slightly different in the type and one paratype; those of the paratype (# 6 6311-CDM) somewhat resemble those of H. herrerai, but the locality data and the contrasting white veins on the hindwing venter suggest that all three specimens are samples of the same population. Hylephila herrerai is smaller with broader fuscous markings above and lacks contrasting white veins below, and the genitalia of H. herrerai differ in the narrower uncus, smaller pectines with inconspicuous tines, and a shorter juxtal median floor. The species has been collected in January, February, and April.
Hylephila pallisteri MacNeill, new species
(Figs, la, lb, 4d, 4e, 15, 16, 36, 37, 58)

Fringes broadly fuscous, terminally pale fulvous. Below, stigma pocket upper element extends well beyond origin of vein Cul and diverges from discal cell about equidistant from origins of veins Cul and Cu2, lower elements large (Figs, la, lb). Orange fulvous as above but broader discally and more restricted basad by fuscous in spaces Sc-R, basal half of Cu2-2A, discal cell, and entire anal cell; costa white and veins R3 to M2 distally white, black bar end discal cell and fuscous spots postmedially in spaces M1-M2, M2-M3, and M3-Cul more or less heavily overscaled with fulvous, and distal to stigma pocket in spaces Cul-Cu2 and Cu2-2a. Hindwing above fuscous, fulvous restricted to streak through lower half of discal cell and a very narrow postmedian macular band Cu2-2A to crescent in Rs-Ml, and weakly along vein 2A to termen, fringes as forewing but more orange. Below fulvous with veins (except M2) from Cul to Sc strongly contrasting white; rounded black spots basally in costal and discal cells, postmedially and marginally in spaces Sc-Rs, Rs-Ml, M3-Cul, Cul-Cu2, and discally in upper half of discal cell; space Cu2-2A fulvous from base to termen, vein 3A distal two-thirds fulvous; fringes more orange than above.

Valva (Figs. 15, 16) in lateral view narrow, basal margin not strongly convex, its length subequal to one and one-half times depth of valva, dorsal margin not greatly concave to caudal beak; in caudal view lower half of horizontal cleft narrow, scarcely one-half width of knobbed upper half. Penis proximally slightly curved dorsad, its length exceeding length of genitalic capsule and about twice; length of valva; titillators asymmetric, the left large, broadly thorn-like, and sclerotically strapped to penis, the right much reduced, narrowly thorn-like, and obscurly strapped to penis; cornuti bidentate, asymmetric, the proximal basally much elongate, the distal not elongate. Juxta with ventrocaudal clefts short, about one-fourth length of juxta; separated median floor reaching caudal margin of juxta. Uncus in dorsal view distinctly round cephalad, abruptly tapered to caudal pectines; the caudal cleft not exceeding pectines cephalad; pectines small, each half longer than broad, anteriorly and posteriorly rounded, the tines few, conspicuous, in lateral view scarcely arched.

Female. Unknown.
Type. Holotype 6, PERU, Cuzco, Ollantaitambo, 111-24-47, 9200 ft., C. J. Pallister (genitalic dissection # 6 3811-JH), in AMNH.
Etymology. This species is named for the collector of the holotype, C. J. Pallister.
Diagnosis and discussion. Two additional specimens have been \seen. One, a male from Yungas (or LaPaz) Bolivia, 1000 m, ex H. Rolle, 1902, R. Oberthur Coll'n. (genitalic dissection # 6 3815-JH) was prematurely returned to the BMNH identified as H. houlleti, but was noted as having identical genitalia to specimen # 6 38L1-JH (the holotype of//, pallisteri). I have not examined this specimen in detail.
A more recent specimen (Figs, lb, 4e, 16, 37, 58) from PERU, Cuzco, Abra Acjanacu, 3600 m. 17-V-84, 6. Lamas (genitalic dissection # 6 6227-CDM), in MUSM, seems to be this species; but it differs in sev-

eral particulars from the holotype: It is much larger with a forewing length of 14 mm. The antennal club is longer so the shaft is about twice the length of the club. The third palpal segment is ventrally entirely fulvous, not black on the distal third. On the wings above the post-stigmal patch is not as broad as in the holotype, and below the stigmal pockets are more robust. The markings are quite similar; but on the hindwing venter there is an extra elongate postmedian black spot in the upper fourth of space M1-M3, and vein M2 is apparent and whitened. The genitalia also differ in that the valva is a bit narrower with the length of the basal margin more than one and one-half times the depth, and the lower one-half of the horizontal beak cleft in caudal view is nearly as wide as the upper half. The penis is not as strongly bent dorsad proximally, and the discal cornutus is unidentate. The juxta has the ventrocaudal clefts long, about half the length of the juxta. The uncus in dorsal view has the lateral margin more abruptly emarginate caudad before the pectines and the caudal cleft distinctly exceeding the pectines cephalad. The pectines are small with each half scarcely longer than broad, and anteriorly as well as posteriorly scarcely rounded, and the tines are numerous and inconspicuous. The gnathos in lateral view is only somewhat divergent ventrally from the uncus. These characters suggest that perhaps this specimen represents a closely related species.
The two specimens are distinctive in the orange fulvous above with broad borders, the very black stigmal elements including the microandroconial mass, and the dark fuscous, orange fulvous, and contrasting white veins below. The specimens were collected in March and May

Etymology. This species is named for the collector of the first two specimens I saw of this species. The holotype was selected because it is in better condition.
Diagnosis and discussion. Hylephila blancasi has superficial markings similar to those of H. galera. One paratype (genitalic dissection # 6 3819-JH) is very like the latter with pale fulvous extensive on the dorsal forewing, the dark markings much reduced, and the forewing subterminal fulvous spots in spaces M1-M2 and M2-M3 slightly offset from the postmedian band of fulvous spots from M3-Cul to Cu2-2A, owing to the fulvous expanded basad in space M3-Cul. Hylephila galera, however, has much broader wings and genitalically belongs with subgroup II. Another paratype of H. blancasi (SEM # 6 9, 23-CDM) has the dorsal forewing subterminal spots reduced and completely separated from a narrowed postmedian band by a combination of a distally expanded subapical fuscous spot and a greatly broadened marginal border. Hylephila blancasi flies in December and January.
The following species, H. tentativa, is remarkably similar to H. blancasi; but the fulvous of the wing

above is much more orange on H. tentativa, the male stigma is less well developed, and the genitalia are somewhat different. The valva of H. blancasi is much broader, the titillators are more robust and the cornuti distinctly bidentate, the juxta is less robust, the uncus in dorsal view is anteriorly more rounded and the pectines slightly larger with numerous, inconspicuous tines, and the gnathos is caudally more or less inconspicuous from above than are these structures in H. tentativa.

Etymology. The specific name reflects the uncertainty expressed in the discussion below.
Diagnosis and discussion. As mentioned, this species is remarkably like H. blancasi; in fact when I first saw this pair of specimens I was convinced they were that species. I was surprised by the apparent disjunction of this population from the rather more northern ones of the known H. blancasi. In comparing seemingly slight differences in color pattern, stigmal characters, and especially genitalia, I suspected that this was not H. blancasi; and since this pair seems to be a male and a female from the same population, I elected to emphasize this, but not without some hesitation—hence the name. The types were collected in January.
The differences from H. blancasi in the male genitalia are discussed under that species. The female genitalia resemble those of H. herrerai in lacking a sclerotized eighth sternite, but they differ from those of that

Etymology. I am delighted to name this remarkable little species for Arthur M. Shapiro, the collector of the only known specimen. Art has provided enormous and continuous support throughout these studies with years of discussion and careful collecting in South America.
Diagnosis and discussion. This small species dor-sally appears to be more black and white rather than black and fulvous, and it does not seem to have a stigma until it is examined under magnification. The single pair of spurs on the metathoracic tibiae is a unique characteristic of this species within the boulleti group of Hylephila, This specimen was figured by Shapiro (1985) in his paper summarizing behavioral and ecological observations of the high altitude pierines he studied. In that paper, he discussed the morphospecializations of the genus Phulia Herrich-Schaffer and suggested that the convergence of the high altitude hesperiid fauna to the "dashed Phulia pattern" of high Andean pierines was owing to adapta-

Description. Male. Head. Dorsally very pale fulvous, with long, black hair-like scales rising from paired, postmedial black scale patches which are separated by smaller, triangular, medial patch on the vertex; pale, fulvous hair-like scales elsewhere except for mixed black and fulvous eyelash scales. Antennae anteriorly pale buffy to white, posteriorly black; club about one-half length of shaft; nudum pale orange to orange brown on apiculus; apiculus about three short segments, its basal width about equal to its length. Palpi third segment black, ventrally mostly pale fulvous to buff, clearly to scarcely emergent from shaggy vestiture of second segment, where anterolateral angles have scattered black hairs. Body dorsally black with scattered, long, pale golden vestiture of hair-like scales concentrated medially, pectus and venter white to pale fulvous. Legs mostly white, fringed fulvous, hind tibiae with two pairs of spurs, the upper occasionally somewhat reduced. Wings. Somewhat pointed apically, not stubby. Forewing average length 10.7 mm [range 9-13 mm] (n = 40). Above, stigma slender, conspicuous, microandroconial mass inconspicuous without magnification, gray or tan to (rarely) yellow, apical and lower brush patches present, poststigmal patch conspicuous but not broad. Fulvous pale tawny, very variable in extent (cf. Figs. 46

and 48); fuscous border if broad and clearly cut by fulvous veins, the Fulvous not reaching termen along veins. Below, stigma pockets slender (Figs. 3a, b), diverging from discal cell cubitus vein about equidistant from origins of veins Cul and Cu2 or usually slightly nearer to that of vein Cul (but see Fig. 3b). Fulvous more extensive, costa and most veins whitened distally to termen. Fringes pale, basal third fuscous, middle third light fulvous, terminal third white. Hind-wings above as forewings, variable, border broad or narrow, usually not cut to termen by Fulvous along veins. Postmedian macular band conspicuous, usually extending ray-like into at least lower part of discal cell from space M1-M3 and from vein 2A to Rs. Vein 2A fulvous from base to termen defining vannal fuscous area. Below pale fulvous to almost white. Costa and all veins whitened, often including vein 3A, vannal area fuscous. Genitalia. Eighth tergite (Figs. 5c, d) with lateral margin broadly concave or sinuate cephalad, not distinctly emarginate just before caudal margin; terminal bristle-sockets rounded in cross section and enlarged before caudal margin (Fig. 7). Valva (Figs. 22, 23) in lateral view broad, ventral margin convex, basal margin straight, dorsal margin slightly concave to caudal beak where knobs dorsad of caudal horizontal cleft few; length basal margin about equal to one and one-half depth of valva. Penis proximally slightly curved dorsad, its length slightly greater than length of gen-italic capsule and less than twice length of valva; titillators large, asymmetric, the left very broadly and the right more narrowly thornlike, both sclerotically strapped to penis; cornuti asymmetric, one long, narrow, and basally very elongate, the other short, thorn-like, both minutely bidentate.

with lateral margins broadly angulate at anterior one-fourth, then emarginate to nearly parallel-sided caudal one-third, where minutely serrate to caudal tip which exceeds width of pectines, caudal cleft scarcely exceeding pectines cephalad; pectines not minute, length each half usually about twice its breadth, anteriorly and posteriorly nearly or quite truncate; the tines many, inconspicuous. Gnathos in lateral view scarcely sclerotized, slightly exceeding pectines caudad, and not very divergent ventrally from uncus.
Female. Head. As male, antennal shaft about twice length of club. Wings. Tawny to very pale fulvous (Figs. 47, 49). Forewing, average length 11.9 mm [range 10-15 mm] (n = 35). Dorsal surface as male; ventral surface pale fulvous much expanded, fuscous border greatly reduced, or faded to nearly obsolete. Genitalia. Eighth ster-nite in ventral view sclerotized and broadly crescentic, its greatest width caudolaterally, its length about one-fourth to one-third its width. Apophysis anterioris in lateral view (Figs. 28, 29) somewhat to scarcely produced cephalad of junction with lamella postvaginalis. Lamella postvaginalis in ventral view narrowly united, each half produced ventro-cephalad forming a slight anterior bulge, not nipplelike, medially not produced ventrally. Antrum dorsally sclerotized and with a longitudinal fold, ventrally caudal and lateral one-half membranous. Ductus bursae well sclerotized, in right lateral view ductal constriction not very abrupt, the sinus U-shaped; left lateral pocket slightly to prominently produced.
Type. Mabille s type, a female, is presumably in the Museum National Histoire Naturelle, in Paris, France. It was collected in Peril.

Andean Nevadas del Aconquija, just west of San Miguel de Tucuman in provincias Catamarca and Tucuman. The males (4 specimens) are somewhat variable in their genitalia (see Fig. 23, # 6 6213, from Catamarca) and may not represent a single species, but I am content to consider them all minor variations of H. houlleti until such time as more and better material can be studied.
Males of H. houlleti have a stigma with a microan-droconial mass that is usually neither conspicuous nor yellow, they have two pairs of metathoracic tibial spurs, and usually lack wing borders above that are deeply and broadly cut by fulvous along the veins. This species is very pale fulvous above, not orange fulvous; and it seems to fly alone, not within the ranges of most other species of the houlleti group, save for H. herrerai. Its range does evidently overlap those of the next species and of H. peruana slightly in a narrow region of Puno, Peru, northwest of Lago Titicaca near the border of Departamento Cuzco (Fig. 59). Hylephila houlleti seems to be on the wing through most of the year except for June through August.
This species is the most commonly collected mem-

ber of the boulleti group. Indeed, I have seen a total of 55 males and 40 females (27 males, 23 females dissected) representing 32 localities in Peru, Chile, Bolivia, and Argentina; but the samples almost always consisted of one to three specimens, except for one locality in Chile and another in Argentina; where the sample was six specimens. It wasn't until the mid-1990s when Arthur M. Shapiro made five collections, under a CONAF collection permit issued 18 November 1994 in Arica, Chile, by Juan Silva, Director, CONAF, 1st region, that samples of up to 25 were taken. Shapiro 1995, in litt. stated that at one locality the H. boulleti "were as common as I have ever seen any skipper anywhere; I could have taken hundreds, if not thousands." The skippers were (in his words) "incredibly abundant on monocultures of the apparent host (oviposition substrate), Deyeuxia breviaristata Wedd., a small wiry grass that grows just (above) the margins of boggy and saline environments."

vored nectar source was a small composite, Werneria, that grows flat on the ground in boggy turf, (fide Shapiro). He observed oviposition on Deyeuxia, often on plants that seemed dry and desiccated, presumably owing to the rains having just started.
Twenty-three ova were recovered by dissection prior to KOH treatment (see MacNeill & Herrera 1999:279) from three females (# 9 6218, # 9 6264, and
# 9 6265), and these averaged 0.8 mm in diameter and 0.58 mm in height. The diameter ranged from 0.75 to 0.83 mm, and the height ranged from 0.55 to 0.65 mm. The three females separately had different averages:
# 9 6218 measured the largest with 9 ova averaging 0.82 x 0.60 mm, and # 9 6265 measured the smallest with 8 ova averaging 0.78 x 0.57 mm. The most common (not average) measurement of the 23 ova was 0.8 x 0.6 mm, a fairly high-domed egg, by and large. The reticulation was very weakly evident at lOOx magnification.

Diagnosis and discussion. In the boulleti group of Hylephila, males of this species are arguably the specimens most easily identified without dissection, because of their conspicuous stigma with its yellow microandro-conial mass, their extremely abbreviated uncal pectines (which can often be seen by merely gently brushing the abdominal tip from above), and their distribution in Peru: north and northwest of the department of Puno, where H. peruana occurs with several other members of the group (see maps, Figs. 58, 59).
This is the member of the boulleti group most commonly collected in Peru. I have seen 22 males and 20 females (18 males, 17 females dissected) from 18 localities in Peru. Flight records suggest perhaps four broods through the year with gaps appearing during March, June, September, and November-December.
Nine ova were dissected from three females (# 9 6377, # 9 6378, # 9 6379) prior to KOH treatment. Two eggs from # 9 6377 measured an average 0.75 x 0.63 mm, and also a pair of eggs from # 9 6378 averaged 0.85 x 0.55 mm. Five ova from # 9 6379 averaged 0.83 x 0.57 mm, and the average of all nine ova is 0.81 x 0.57 mm. The most common measurement for all the eggs was 0.85 x 0.55 mm. The eggs were all very similar to eggs of H. boulleti including the very weak reticulation at 100 x magnification, although the ova of this species proportionately do not seem to be as highly domed as are those of H. boulleti.

and scanning electron micrographs were produced by Darrell Ubick at the CAS. Arthur Shapiro continued his tireless collecting efforts and observations in South America, and I particularly want to thank Juan Silva of Arica, Chile, Director of CONAF, First Region, for granting A. M. Shapiro the collecting permit that made his efforts in Chile possible. The artwork was partially funded by a CAS In-House Research Fund FY 1994-95 grant, and some of the manuscript and publication costs were covered by CAS Entomology Research Funds. Julie Parinas, Paul Arnaud, and Vincent Lee again repeatedly were tolerant and helpful in solving my many entreaties for assistance with my "new" word processor. John Burns and George Austin very kindly read the manuscript and offered numerous suggestions which much improved the paper, for which I am most grateful. My thanks to them all.
