Godman & Salvin (loc. cit.) have given excellent figures.
The genus Oenomaus Hiibner ([1819], Verz. bek. Schmett. (5): 76) is nomenclatorially available for ortijgnus, which was selected as its type species by Scudder (1875, Proc. Am. Acad. Arts, Sci. 10: 231), and has been so used by Kaye (loc. cit.). The genus is apparently needed, but has never been described:
Antennae rather short, with a long, gradually incrassate club. Frons fuscous with white borders, the scaling subappressed or partially erect. Eyes with short but rather dense hair. Scent pad present, simple, ovate and sharply defined, located at the anterior distal angle of the cell-end. Hind wing with a moderate tail at Cu2 and a very short one at Cu1. Male genitalia: Tegumen short; uncus lobes slender, well notched between; falces normal; vinculum without shoulder process, tapering ventrad, with a diagonal straight strut at middle; saccus over twice as long as width at middle; valvae joined along basal third, slightly divergent thence distad, apically biramous, the rami distally directed and subparallel, mesad ramus shorter; dorsally each valva with a longitudinal keel; penis about 1.9 times as long as combined length of saccus and valvae, slightly and gently upcurved at apex, without terminal keel; cornutus single, conical, terminal, very large (nearly filling the cavity of the penis shaft), distally pointed and minutely spiculate all over the sides, save for the terminal point.
Knowledge of neotropical hairstreaks is still too incomplete to dwell at any length on the relationships of Oenomaus to other genera. Among those I have examined it seems to come closest structurally to Ministry-mon Clench (leda Edwards; clytie Edwards) or Paiwarria Kaye (venu-Uus Cramer), although it is not very close to either. It also shows some resemblance to two related genera being described in another paper (among whose species are included, respectively, brescia Hewitson and coelebs Herrich-Schaffer). Here again, the relationship is not particularly close. Among the most distinctive traits of Oenomaus is the large, conical, spiculate cornutus, which I have seen in no other genus.

NEW DISTRIBUTION RECORDS FOR THREE SPECIES
FROM ARKANSAS, LOUISIANA AND TEXAS
(HESPERIIDAE, PAPILIONIDAE)
by Roy O. Kendall
135 Vaughan Place, San Antonio, Texas
Erynnis juvenalls (Fabricius). Lambremont (1954) and Ross & Lambremont (1963) recorded juvenalls from four Louisiana Parishes: East Baton Rouge, Orleans, Tammany and West Feliciana. Vernon Parish is now added. On 18 March 1963 at a spot near the Sabine River, about 14 miles southwest of Anacoca, adults were found quite plentiful in a small clearing. It is estimated that no less than 100 individuals were seen within a two hour period. Twenty-one males were collected. It is doubtful that any females were present at the gathering. One very interest-

ing observation was the perching preference many of them showed for pieces of charred wood at an old camp fire. They were exceedingly wary and difficult to stalk. The writer was accompanied by his 80 year old father-in-law, Lawrence Alford, who collected six males, testing his skill with a butterfly net for the first time.
The following Texas records are also given: Polk County, 16 March 1963, along a forest trail just east of the Alabama & Coushatta Indian Reservation, 12 males were collected. Many more were sitting in the road sunning themselves or chasing each other. San Jacinto County, 16 March 1963, at Double Lake camping area in the Sam Houston National Forest, three males were collected; others were seen. Also, same day near Cold Springs, one more male was collected. Uvalde County, 10 March 1962, at Garner State Park, two females were collected; both very fresh. These two specimens were determined by Dr. John M. Burns, Wesleyan University.
Euphyes (Atrytone) dukesi (Lindsey). Mather (1963) found dukesi distributed over seven states: Alabama, Louisiana, Michigan, Mississippi, North Carolina, Ohio and Virginia. Arkansas is now added to its distribuÂtion. On 27 September 1962, just south of Pine Bluff, Jefferson County, off Ohio Street in the vicinity of Imbeau Bayou, two females were collectÂed. They were somewhat worn and were feeding on blossoms when netted. The habitat was along a county road with water filled ditches and overgrown with vegetation. Other individuals were seen.
The specimens were determined by H. A. Freeman.
Graphium marcellus marcellus (Cramer). Lambremont (1954) and Ross & Lambremont (1963) recorded marcellus from seven Louisiana Parishes: Catahoula, Iberia, Lafayette, Sabine, Union, Washington and West Feliciana. Vernon Parish is now added. On 17 March 1963, near Leesville, one adult was seen feeding on blossoms high in a tree. The following day, near the Sabine River about 14 miles southwest of Anacoca, some 15 adults were abserved as they flew up and down forest trails. Three males were collected. The exact spot is well identified by Geodetic Survey Marker: TT32I, 1940, 124' above sea level. It was interesting to note how males would alight on bright colored objects and then go through a courtship maneuver. One was collected on an old Hawaiian Punch can, another on an oleomargarine wrapper. Belatedly, it occurred to the writer that had one of the captured specimens been used as a decoy, the collecting would have been much better.
