wing a hoary gray appearance. Transverse lines blackish; basal 

 line from costa to anal vein. T. a. line oblique, bent outward before 

 anal vein in the $ , straight in the 9 ; t. p. line bent outward 

 below costa, where it is merged with a dark subapical shade, and 

 more broadly in the median area, whence it curves inward to the 

 inner margin, where it is followed by a small pale area. Sub- 

 terminal area powdery gray; a tine, dark terminal line. Fringes 

 eoncolorous. Eeniform faintly indicated in all types and orl)ic-

The species looks not unlike an Acopa, but is quite distinct from 

 that genus. 



MOMIX.E. 



Although no members of this sub-family have yet been reported 

 from our limits, we think that it must be accorded a place in our 

 lists for the reception of Grote's genus Tricliocosmia and both of 

 the included species, inornata Grt. and drasteroides Smith. In 

 both of these species the eyes are sparsely hairy and vein Ma of 

 the secondaries is very evidently nearer to M3 than to Mj. They 

 run to this subfamily in Hampson's key to the subfamilies of Noc- 

 tuida? (Cat. Lep. Phal. B. M. IV, 3 and 4).
