MONOGRAPS OF THE WASPS OF BRITISH INDIA. 487 



S . FeminjB similis ; clypeo albopiloso ; apice late truncate, minutissime 

 tridentato, nigro, macula basali fulvo-ferruginea. 



Long. 5,12mm.; c?j8mm. 



5 . Clypeus with the lamina porrect, free from the base, nearly as long 

 as broad, convex and truncate at the apex. Antennse inserted about half 

 as far again from the anterior ocellus as from the base of the clypeus ; the 

 second joint of the flagellum nearly half as long as again as the third. 

 Eyes almost parallel ; posterior ocelli further from the eyes than from each 

 other. Mesopleuree not tuberculate ; first abdominal segment nearly as 

 long as broad ; second ventral segment with a raised area at the base ; 

 pygidial area broadly ovate, narrow at the base, broadly truncate at the 

 apex, less than half as long again as broad. Finely punctured rugulose, 

 the median segmont and mesopleurse rugose ; enclosed area at the base of 

 the median segment finely obliquely striated at the base, finely punctured 

 at the apex. First recurrent nervure received a little before the middle 

 of the second cubital cell. 



S . As in the female ; but the clypeus is convex, truncate at the apex, 

 with three very minute teeth on the apical margin. First abdominal 

 segment about one-quarter longer than the greatest breadth. Pygidial 

 area not much longer than broad, slightly narrowed at the extremities. 

 Closely and finely punctured. 



Habitat— ^h.?is\ Hills. 6,000 ft. August. 



I took both sexes at Shillong ; the female not having been described 

 previously. It is remarkable in having the raised area at the base of the 

 second ventral segment together with the free lamina on the clypeus of the 

 female.

5. Clypeus with a porrect lamina from the base, the lamina nearly 



twice as broad at the apex as long, broadened to the apex and deeply and
