Another female Ames, Iowa, October 15, 1897 (State. Coll. Iowa)

 narrower. 



Group 3 



Besides the characters mentioned in the key, common features of 

 species of this group are aedeagus bifid, more or less caliper-like, 

 and dark spots anterior to crossveins.

1. Dusky spots anterior to cros.sveins rather elongate, sometimes forming an 



iU-defined band 2 



— Spots anterior to crossveins not elongate 3

TYPHLOCYBA ANTIGONE, new species 



Male. — Head and thorax pale j^ellowish, tegmina nearly to cross- 

 veins, light sulphur yellow ; somewhat elongate spots anterior to 

 crossveins 2, 3, and 4, faintly dusky; apical cells hyaline; underparts 

 stramineous. Hypopj^gium: Posterior lateral margin of ninth seg- 

 ment distinctly emarginate, the upper angle developed as a process 

 resembling in shape, as seen from above or below, a thumb and index 

 finger, but appearing as an acute tooth as seen from side (fig. 76), 

 the finger much longer than the thumb and decidedly incurved: 

 claspers in no way unusual, aedeagus short, widely bifid apical ly.
