several near base of wings, and some branches of radial sector and 

 cubitus black at origin. Wings long, acute, gradates very oblique, 

 parallel, each of six veinlets, inner as near outer series as to the radial 

 sector, marginal forks two and one half times as long as broad, about 

 20 costals before stigma, divisory ends beyond the cross-vein; in hind 

 wings three inner and seven outer gradates, these black, other venation 

 green, stigma in both pairs very long, deep green. Pronotum slender, 

 about one and one half as long as broad, tapering in front.

Runs to Ch. gonzalezi but differs in markings of wings, and more 

 especially in the position of the inner gradate series, which is placed 

 nearly transversely across the wings. Face yellowish, a faint reddish 

 stripe on each cheek, last joint of palpi marked with dark, antennae 

 pale, vertex green, thorax and abdomen deep green, pronotum with 

 side margins red, and also the sides of thorax above base of wings; 

 legs pale; wings with green venation, in fore wing the stigma dark at 

 base and faint clouds along the outer four cross-veins between radius 

 and radial sector, both gradate series and the last branch of the radial 

 sector to median vein margined with pale brown; hind wings unmarked, 

 except the stigma is a darker green. Wings are moderately slender, 

 nearly acute at tips, the divisory ending before the cross-vein, the 

 outer gradate series of six veinlets curved as to be nearly parallel to 

 the outer margin, the inner series of five veinlets nearly transverse, 

 none much disjointed; marginal forks fully three times as long as 

 broad; about 16 costals before the stigma in fore wings; in hind 

 wings the gradates, of five and six veinlets, are subparallel, and more 

 oblique than in the fore wings. Pronotum a little longer than broad, 

 narrowed in front. 



Expanse 24 mm.
