Species. — penumbrata Hulst, n. sp. 



S. penumbrata n. sp. — Expands 14-16 mm. Palpi jet black, front dark 

 fuscous ; head tuft and thorax smooth, even mouse-gray. Abdomen dark fuscous 

 gray, slightly interlined with lighter color ; all wings blue-gray or light mouse 

 color with a violet tinge in certain lights with three or four indistinct dark spots 

 along costa ; in old specimens there is an indication of cross-lines in the more 

 mottled surface, this being more shown extradiscally on hind wings ; discal spots 

 fine, black, not very distinct ; marginal line dark gray, indistinct, as though the 

 wing edge were black, and this covered over with gray scales and showing 

 through ; beneath even light mouse-gray, discal spots and marginal lines faintly 

 showing.

Palj)i v^ery short, .slender; front short scaled ; antennae of % sub- 

 dentate with fa.scicles of hairs; fore wings probably with 12 veins; 

 hind wings 8 veins, the iiiner margin in % with an edging of long 

 coar.se hairs near base; hind tibi;e of S without spurs and with 

 .<trong hair pencil. 



The unique specimen of the single species is in poor condition, and 

 I am unable to examine the venation fully. The tufting on the 

 inner margin of hind wings of the % warrants generic separation.
