 deep red beneath ; mandibles stout, with a large orange 

 stripe ; tegnlse light ferruginous. Wings strongly yellowish 

 on basal half, nervures ferruginous ; second subuiarginal 

 cell very broad, receiving the first recurrent ncrvure a con-

 scape, femora, &c. ; it is, however, closely allied.
