Neither will the wing shape separate the two genera, for this 

 appears to be a variable factor in specimens of the same species from 

 the same locality in both genera. 



We feel, however, that we do not care to place Rancora as a 

 straight synonym of Lathosea for two reasons. The first is that we 

 possess only a single specimen of the type species of the genus Ran- 

 cora (strigata) and that is without a head. The second is the char- 

 acters mentioned in our first two paragraphs which seem slight but 

 constant. 



The following arrangement is suggested : 



Lathosea, eyes very heavily ciliated, considerable hair on palpi below, vesti- 

 ture appearing very rough, black spot and bar on the secondaries below^, de- 

 veloping, present or absent. 



Rancora, eyes somewhat less heavily ciliated, at least some hair on the 

 palpi below, vestiture intermediate to Cucullia, black spot and bar on the secon- 

 daries below always conspicuous. 



Cucullia, eyes heavily ciliated but the cilia not as long as in Rancora, 

 palpi somewhat hairy below often nearly as in Rancora, but the black spot and 

 bar is very vestigial, only the barest trace of it appearing in some specimens of 

 the darker species. The vestiture is also inclined to be smoother and the insects 

 less heavy bodied than Rancora or Lathosea. 



With these facts in mind albida, Sm. is withdrawn from Cucullia 

 and placed in Rancora. 



We will not be surprised if a revisional work will ultimately lump 

 the three genera into one. Temporarily we consider it best to hold 

 them separate, and in the order in which we here place them. 



We do not care to discuss the probably generic position of Bra- 

 chionycha (Asterocopus, Boisd.) as we have only four specimens of 

 borealis, Sm. and one of the European neheculosa. On these five 

 specimens, however, the tegulae lay nearly flat, altho in the European 

 specimen there is some tendency toward a slight pointing. Nehe- 

 culosa seems structurally congeneric with borealis, altho the primaries 

 are slightly narrower and more pointed in the latter species in the 

 four specimens in the Barnes Collection.
