Smaller, darker, and narrower winged than bufalis, the male with- 

 out fovea in the cell. One specimen from Costa Rica has been labeled 

 Stenia gelliasalis by Mr. Schaus, but not correctly, I think. 



PILECOCERA STERCORALIS Moschler.

More or less ocher shaded, the wings more sharjily pointed at apex 

 than in hufalis Guenee. This name is given as a synonym of hufalis 

 by Hampson, but I believe that two species are clearly indicated.

Sunilar to pulveralis Druce, but smaller, the apices of both wmgg 

 mth a large blackish patch. Lines of hmd wing well divided, form- 

 ing two across the wing without trace of cross-line. Expanse, 15 mm.
