Genus Agrias, Boisd. MSS.. 



Head rather broad, clothed with hair ; eyes nearly round or slightly 

 oval, prominent ; maxillae rather longer than the thorax ; labial palpi 

 rather widely separated, ascending, thickly clothed with scales, which 

 in front are long ; basal joint curved, very short, second more than 

 twice the length of the first ; third short, pointed. Antennae elon- 

 gate, about three-fourths the length of the body, gradually thicken- 

 ing from the base to the apex. 



Thorax large, elongate-ovate, truncate posteriorly, hairy. Anterior 

 wings subtriangular, the anterior margin rounded, about one -half 

 longer than the outer, which is nearly straight or slightly sinuate ; 

 the inner margin rather longer than the outer, straight. Costal 

 nervure stout, extending beyond the middle of the costa ; subcostal 

 nervure throwing off its first nervule about the middle, the second 

 a short distance before the end of the cell, the third at some distance 

 beyond the cell, the fourth rather more remote from the third than 

 that is from the fourth. Third subcostal nervule terminating at the 

 apex ; fourth running close to the third until near the apex, then 

 bent downwards and reaching the outer margin about half-way be- 

 tween the apex and the termination of the fifth subcostal nervule ; 

 upper disco- cellular nervule very short, middle above twice the length 

 of the upper, lower nearly twice the length of the two other com- 

 bined ; third median nervule considerably curved. Posterior v/ings 

 obovate ; the fold for the reception of the body ample, anterior mar- 

 gin rounded, outer slightly dentate, sinuate ; precostal nervure 

 simple ; cell closed by a slight disco- cellular nervule. 



Anterior feet of the female small, the femur and tibia about of equal 

 length, the tarsus short, four-jointed, the basal joint longer than the 

 rest combined, which are all short, transverse, and nearly equal. 

 Middle and posterior feet stout, rather short ; thelibiae spiny within, 

 the spurs very short ; the tarsi spiny at the sides, the first joint spiny 

 below also, equal in length to the rest combined ; claws small, curved ; 

 pulvillus large. 



Abdomen short, tapering.
