 superans, apice depressum. Pedes breves ; tibiae fimbriatse.

 vexa, margine exteriore convexo perobliquo.

 stout ; tibiae fringed ; hind-tibiae with four long spurs. Wings

 Mas. — Viridescente-cinerea, capite thoraceque nigro-con- 

 spersis, abdomine rufescente cinereo basi luteo, alis anticis 

 nigro-conspersis, lineis nigris indeterminatis hinularibus, alis 

 posticis rufescentibus.
