antennae; may lie easily distinguished from those species by the bright 

 color and contrasted maculation. 



Oncocnemis ocscurata sp. nov. (Plate II, fig. 5.) 



S . Head, thorax and primaries dark fuscous-gray, with all the macula- 

 tion very obscure; collar with a black line at base; primaries with t. a. and t. p. 

 lines and median shade marked by black spots on the costa, otherwise not 

 traceable ; black basal dash extending to the clavif orm ; beyond the presumable 

 course of t. p. line the subterminal space is slightly irrorate with white scal- 

 ing; obscure black broken terminal dashes in the interspaces extending back- 

 ward into the subterminal area; s. t. line wanting; orbicular narrow, oblong, 

 broadening outwardly, outlined in white, joined to reniform by a white bar; 

 reniform dusky, obscure, outlined toward orbicular distinctly with white; 

 claviform faintly marked in white ; fringes dusky with yellowish basal line. 

 Secondaries white, hyaline, with narrow, sharply defined, dark terminal border, 

 not attaining anal angle ; a small dark discal spot. Beneath whitish with small 

 discal dot and blackish terminal border to both wings; secondaries iridescent. 

 Expanse, 26 mm.

This obscurely market! species belongs in the poliochroa-colorado 

 group, having orbicular and reniform connected. It can be mo.st 

 readily separated by its hyaline white secondaries with narrow terminal 

 border not attaining anal angle ; this border is much narrower than 

 in poliocliroa Hamp. 



Oncocnemis a.strig.\t.\ sp. nov. ( Plate II, fig. 4.) 



Front, head and basal portion of tegulae deep black brown ; upper portion 

 of tegulae light gray; thorax and primaries deep gray sprinkled with minute 

 black atoms, primaries suffused terminally with brown; all maculation wanting, 

 veins terminally slightly defined by black; fringes fuscous. Secondaries shaded 

 along costa and outer margin with smoky brown but not definitely banded; 

 veins in outer area marked with dark scaling. Beneath primaries gray-white 

 sprinkled with gray and brown scales along costa and outer margin ; secondaries 

 hyaline with gray costal scaling; a faint postmedian line composed of dark 

 venular dashes on both wings, most prominent on secondaries. Expanse, 34 mm.
