base ; three to four short peg-like apical spines anteriorly. Spur not longer than 

 the first tarsal joint which bears about thirteen heavy spines arranged as follows : — 

 three antero-apically, four to five on the plantar aspect and the remainder on the 

 posterior edge ; joints 2, 3, 4, with six, five and four spines, respectively. The 

 tarsal proportions are 40 : 18 : 15 : 14 : 25. Hind legs : coxa quadrate, reticulate 

 outside on apical ventral half, where there are a few bristles. Tibia with three to 

 four spines posteriorly and subapically and ten to eleven in a transverse apical comb ; 

 the spur fine-pointed and short, and about half as long as the first tarsal joint. 

 Proportions of the tarsal joints as in the mid legs, but the first joint one- fourth 

 shorter.

Propodeon deeply excavated to receive the abdomen ; almost separated into two 

 smooth triangular sclerites above. The pleurae likewise smooth, but with trans- 

 verse rugae indicated ventrally. The small, oval spiracle lies anteriorly in the 

 extreme angle between notum and pleurae, with three to four bristles. 



Abdomen. — The dorsal surface smooth and bare, except near the extreme apex. 

 Tne overlaps of the tergites bear two to four bristles ; the U-shaped seventh tergite 

 bears anteriorly 3, 3 and 2, 2 bristles ; there are also median, post-median and 

 posterior rows of about 5, 5, 4 bristles, respectively. The nearly circular spiracle 

 has one bristle in front, one behind, and one on each side. The ventral surface bears
