 fore part not produced beyond eyes; vertex elevated and 

 bearing anterior ocellus at the extreme apex. Cheeks parallel 

 and not set with spine-bearing warts. Eyes comparatively 

 large. AnienncR long and slender, longer than the head and

 and slender. Tube exceptionally long, four times the length 

 of the ninth abdominal segment, and twice the length of the 

 head.

Type — Pamirothrips gracilis mihi. 



Panurothrips may be easily separated from allied genera 

 by the form of prothorax as well as by the exceptionally long 

 and slender tube. 



Panurothrips gracilis sp. n. (PL VII., figs. 7, 8). 



$. Length 5*2 to 6"o mm.; breadth of mesothorax about 

 o'55 mm.; length of tube i"o mm. 



Colour dark chestnut brown, almost black ; antennse and
