upper ; the lower radial is very slightly depressed at the base ; the first branch arises 

 far beyond the middle of the median nervure, the second at the lower angle of the cell ; 

 the third median segment is very short and almost in a line with the discocellulars. 

 The secondaries are rounded at the anal angle ; the discocellulars are very faint. The 

 abdomen is long and slender, extending beyond the anal angle of the secondaries. 

 The hind tibiae have two pairs of spurs. The primaries are without trace of a brand 

 in the male. 



The genus is confined to the New World, ranging from the Southern United States 

 to Peru. A. arene is widely distributed in Tropical America, extending northwards to 

 a little beyond our frontier.

This is a common insect in our country, just entering the Southern United States in 

 Arizona, and extending southwards to Peru ; it also has a considerable range in altitude, 

 since we have specimens from the hot Polochic Valley and from elevations of 9000 feet 

 in Mexico. 



The fuscous coloration on the upperside of the primaries varies in extent, the streak 

 at the end of the cell being often obsolete in the male. The females are considerably 

 darker, the cell being som3times entirely fuscous in this sex. 



The present species is a very close ally of the Colombian A. melanoneura, Felder, the 

 type of which we have seen, but differs in the absence of the dark streaks above and 

 the uniformly pale secondaries beneath. For the genitalia of the male, see Tab. XCII 

 fig. 38.
