Group STEIR0D0NTIITES. 



Steirodontia, Brunner v. W. Monogr. der Phaneropt. p. 356. 



This group includes the largest species of the tribe Phanopterinae, in which the 

 dorsal field of the male elytra presents the most typical characters (of. antea, p. 312). 

 In the females the dorsal field of the right elytron has its inner margin hyaline, limited 

 or divided by a stout longitudinal vein, and pectinated by thick transverse venulae ; 

 outside the longitudinal vein it is closely reticulated, with more or less hyaline cells. 

 On the right elytron the speculum is large and membranaceous. The ulnar vein of 

 the wings often bears four branches.
