urcct, end member comparatively long. Maxillary palpi pencil-tufted, tlie bilobed 

 members heavy, long, the penciling very long and heavy. Antennal process short, 

 long scaled. Wings with heavy costal fold and vitreous spot beneath in (^. Legs 

 rather heavy, loosely scaled, tarsi spinulated, on fore legs only at tip. Genitalia with 

 (urcate base of uncus curved upward. Venation as in Zrt«///«//^^, but 6 is separate 

 in fore and hind wings, and lo and ii are stemmed in the fore wings. 



I am not altogether certain this venation is constant, so far as vein 

 6 is concerned. The specimens I have examined vary so much that 

 others may be found to correspond with Lanthaphe. In that case the 

 genus would rest on the stemming of lo and ii in the fore wings.

Labial palpi blackish-brown, varied with whitish. Thorax pale grayish, varied

line, and shaded toward the base with blackish ; on its external margin is a line of 



raised scales. The subterminal line is pale grayish, angulated and margined intei- 



nally by a blackish line, and externally by a fauiter one produced into points on the 



nervules. The hinder marginal line is black. Sometimes in the female base of the 



wing is whitish, slightly touched with luteous. Expands, 22 to 27 mm. 



Can. , Eastern U. S. to Texas. Feeds, I have been told, on Locust.
