 Hesperia ? White: 



" Head round, eyes large, forehead broad. Maxillae rather long. 

 Labial palpi short, clothed with long dense scales; first joint short, 

 second more than double the length of the first, tapering towards its 

 tip ; third about equal in length to the second, subcylindric, tapering 

 towards the apex. Antennae with a stout, short club, more or less 

 mucronate at the apex, the mucro mostly if not always with a tuft 

 of scales at the point. Thorax stout. Fore wings triangular, the 

 costal vein terminating about the middle of the costa, the subcostal 

 terminating in five veinlets, of which the first and second are thrown 

 off before the disco-cellular veinlet, the third almost immediately 

 beyond it, the fourth rather further from the third than this is from 

 the second ; discal veinlets almost atrophied at their origin, the first 

 connected with the subcostal veinlet, the latter with the third median 

 veinlet by a very short disco-cellular; the discal veinlet itself 

 almost atrophied, running nearly parallel and immediately in front 

 of the median ; third median veinlet much bent at its origin. Hind 

 wings subovate ; costal vein long ; subcostal ending only in two 

 veinlets; upper disco-cellular veinlet wanting; discal vein distinct
