Hah. Guiana, Cayenne (Mus. Genavense). 



This species is remarkable from the fact that it presents intermediate characters 

 between the males and females of A. concinna. The elytra ( $ ) are narrower than usual 

 in the females, but still broader than in the males. The wings (.$ ) are almost as 

 narrow as in the males, and they have nearly the same coloration as in A. concinna^ 6 . 

 The abdomen ( $ ) is also narrower than in that species.]

Var. Vitta fusca alarum anterius dilatata, apicem campi antici tegens, macula vitrea apicis campi intermedii 

 et antici vitrea {semirufa, Westw.). 



Hab. Amazons (Gerstacker), Ega (Westwood). 



Westwood mistook the sex of his type, on account of the slender form of its 

 abdomen, which resembles that of the males of the allied species. The green 

 coriaceous elytra and the coloration of the wings prove that Westwood's insect is 

 a female.]
