 is characteristic and distinctive.

Hahitat.—Aiizoim. 



One S , one 9 . Collection Hulst and Smith. Belongs to the fur/tirata 

 group. The $ antennae are simple, the primaries rather small, apices 

 obtuse, outer margin rounded. The side pieces of the $ genitalia are 

 broad, suddenly bent and narrowed near the tip, which is somewhat 

 dilated, lappet like, and inwardly fringed with spinules. The superior 

 margin of the side piece is thickened and the upper angle of the bend 

 is somewhat prominent; there is no separate clasper. The species is 

 rather closely related to peredia, but distinguishable at a glance by the 

 dark color, obsolete maculation, and small size. T-here is an indistinct 

 tuft behind collar.
