 the head, relative length of joints 3 to 8 as follows : 26 : 26 : 21 : 21 : 3 : 5. Three 

 and four sharply constricted apicaUy, and furnished with long forked trichomes. 



Prothorax about as long as head and 1"35 times as broad as long ; setae at 

 posterior angles about G"35 the length of the prothorax. Pterothorax large, broadest 

 across mesothorax, where it is nearly as broad as long. Legs normal, rather stout, 

 the hind tibia being furnished with a series of short, slender spines from before the

 Costal spines of fore-wing numbering over 40, somewhat slender and increasing in
