Genus XIII. CALLIDRYAS Baud. 



Boisd. et Leeonte. Icon. Lep. et Chen. Am. Sept. 73. (1829). 



Comas God 1 ., Horsfield. 



Catopsilia, Murtia, Phcebis, Colotis, Htibn. 



Head of moderate size, hairy. 

 Eyes round, prominent. 

 Labial Palpi longer than the head ; the first and second joints, clothed with scales and hairs; the 



third with short appressed scales. First joint subcylindric, compressed internally ; the second 



about two thirds the length of the first, oval, concave internally ; third joint mostly round or 



oval, sometimes elongate in the females, always much smaller than the second. 

 Antennae rather short, gradually thickening from a little beyond the middle into a somewhat oval 



club, not truncate at the apex. 

 Thorax not remarkably stout, clothed rather sparingly with hair. 



Anterior Wings subtriangular. Subcostal nervure four-branched; the first nervule thrown oft* 



beyond the middle; the second a little before the end of the cell; the third nearer to the cell 



than to the apex. First discoidal nervule united to the subcostal for only a short distance 



beyond the cell. Internal nervure short, running into the submedian. 

 Posterior Wings subtriangular, rounded. Discoidal nervure appearing to be a third subcostal. 



Abdominal channel ample. 

 Legs rather slender ; the posterior tarsi elongate. Claws stout, deeply bifid. Paronychia broad, 



thick, villous, rounded at the apex, equal to the claws. Pulvillus jointed, longer than the claws, 



the last joints broad. 

 Abdomen moderately stout, not equal in length to the abdominal margin of the wing. 



IjArva smooth, cylindrical, tapering to each extremity. 

 Pupa much arched, tapering to each extremity, smooth. 



Callidryas differs from Eronia in its four-branched subcostal nervure: from Gonepteryx in having more elongate 

 antennae, not truncate at the apex. The wings are never angular or falcate, as in Gonepteryx ; but one species has the 

 anal angle prolonged into a kind of tail, as in Salamis and Amathusia. This is the only instance yet known where 

 such a structure occurs in this family. 



The Lakv.e of the species whose metamorphoses are known are mostly green or yellow, with a pale lateral stripe ; 

 tin' surface inure or less granulated or shagreened, the granulations sometimes black. Their food appears most commonly 

 to be some species of Cassia ; Callidryas Neleis, according to M. I'oey, feeds on Poinciaria pulcherrima. 



The PoPiE are more or less navicular, with the thoracic segments much swollen; are considerably arched, never 

 tuberculated.
