cells by a cross-vein, but simple, as in Trichoptera, Lepidoptera. 

 and Diptera. Median cell sliorter and broader than in Nanno- 

 chorisla; the three veins running into the thyridium becoming- 

 hyaline at that point, (as in jSanriochorista, but less markedh' 

 so) so as to form a thyridial hiatus. Sc ends up with a curve 

 upon R, in the forewing, not far from the pterostigma; in hind- 

 wing, Sc is very short, and ends upon the costal border well 

 before the origin of Pts.
