requires from one to about 9 months to complete its life cycle (exclusive of adult).
It may, therefore be concluded that the insect may have up to about 7 overlapping generations in a year. Normally, in the field it probably has fewer.
Field surveys revealed the presence of all the stages on the host plants throughout the year.
Natural Enemies
Thompson (1946) reported Apanteles aristolochiae Wlkn. as a parasite of this butterfly. No parasites of eggs or larvae were found during this study.

A NEW CALL1THOMIA (ITHOMIIDAE) FROM BOLIVIA John H. Masters1
P.O. Box 7511, Saint Paul, Minnesota
During 1962-1965 I received several large consignments of Bolivian Ithomiidae from Franz Steinbach of Cochabamba, Bolivia. Perhaps the most interesting specimen among these is an unique and previously un-described Callithomia. The late Dr. Richard M. Fox, acknowledged expert in the Ithomiidae, examined this specimen, recognized it as a new species and intended eventually to describe it himself. With the death of Dr. Fox on April 28th, 1968, I have assumed the task of describing the insect and take pleasure in naming it after him.

Callithomia foxi Masters, new species
Male: Upperside of both wings (figure 1A) transparent with black markings outlining veins and wing margins. Black markings widening on both wings at costal and inner margins, wing apices, at end of discal cells and along vein Cui. Cu on hindwing and basal parts of veins Cu2 and 2V yellow. Inner margin of forewing sharply concave. Costal margin of hindwing sharply humped at raised oval "Ithomia patch" from there concave to outer angle.
Underside of wings (figure IB) a mirror image of upperside except for eight small white spots in black wing margins—two at apex of forewing (also a dimunitive in M2), four at anal angle and two at apex of hindwing. Transparent areas with a yellowish cast, viewed from below.
Male genitalia figured (figure 2). Length of forewing: base to tip, 29 mm. Female: Unknown.
Holotype male: Bolivia, Todos Santos, Prov. Chapare, Dpto. Cocha-bamba (300 meters elevation), July 1964. Deposited in Carnegie Museum, Pittsburgh, Pennsylvania.
Dr. Fox (in litt.) believed that this specimen was the only example of the species in American collections, but noted that there were a couple of examples resting unnamed in European collections. The sub terminal spine on the aedeagus places Callithomia foxi in that section of the genus

that includes xantho (Felder), methonella (Weymer), inturna (Fox), epidero (Bates), lenea (Cramer), drogheda (Weeks) and zingiber Fox. Of these seven, C. epidero, methonella, xantho and interna have a strong resemblance to C. foxi. Callithomia xantho and interna, and to a lesser extent methonella, are separable by the lack of heavy black scaling along vein Cui and the end of the cell, this is especially noticeable on the hindwings. Callithomia epidero and methonella have red to brown patches at the anal angle of the hindwing, that are lacking in C. foxi. None of the species in the other section of the genus have a similar appearance.
