the apex of the discoidal cell, first, second, and third subcostal 

 nermles with their bases almost equi-distant, ,/bw^A subcostal with its 

 base half as near to the base of the third subcostal as that vein is 

 to the second, terminating at the apex of the wing, terminal 

 portion of subcostal nervure or fifth subcostal nervule with its 

 base almost touching that of the fourth, terminating on the outer 

 margin far below the apex of the wing; discoidal cell long, narrow; 

 upper disco-cellular nervule straight, strongly outwardly oblique, 

 very short; middle and lower disco- cellular nervules almost in the 

 same straight line (the lower a little concave), the lower a little 

 longer than the upper, both veins taken together strongly inwardly 

 oblique; second median nervule arising some little distance before the 

 lower end of the cell, first median nervule arising much nearer to the 

 base of the wing than to the point where the second median is given 

 off; submedian nervure slightly recurved; internal nervure short and 

 quickly running into the submedian nervure, with which it entirely 

 anastomoses. Hindwing, costa strongly arched at base then straight 

 to apex, which latter is somewhat acute in the male, rounded in the 

 female, outer margin rounded, inner margin convex ; costal nervure 

 almost straight, terminating just before the apex of the wing; first 

 subcostal nervule originating some distance before the apex of the 

 cell; upper disco-cellular nervule straight, very slightly outwardly 

 oblique ; lower disco-cellular also slightly outwardly oblique, at first 

 concave, then straight, a little longer than the upper disco - 

 cellular ; discoidal nervule very fine, straight, arising at the point of 

 junction of the disco-cellular nervules ; second median nervule 

 arising just before the lower end of the cell, first median arising 

 much nearer the lower end of the cell, than the base of the wing ; 

 submedian and internal nervures straight. Type,* the Papilio 

 eligius of Cramer. 



This diagnosis has been made from bleached wings of both sexes 

 of the " Hesperia" leucocera, of Kollar, from Simla, and of the 

 " Papilio " eligius of Cramer from the Amazons, for the specimens 

 of which latter I am indebted to Dr. 0. Staudinger. All the species 

 of the genus settle with wide outsjaread wings, which at once dis- 

 tinguishes them in life from the genus Notocrijpta, mini, the species 

 of which rest with wings folded upright over the back. C. leucocera
