Long. 10 mm. 



5 . Head very large and broad ; middle lobe of the clypeus short 

 broader than long, the lamina free at the apex and truncate, armed with 

 two blunt teeth ; lateral lobes of the clypeus very broad, with a small tooth 

 close to the inner margin. Antennre inserted a little further from the 

 anterior ocellus than from the base of the clypeus, the second joint of the 

 flagellum a little less than half as long again as the third. Eyes strongly 

 diverging towards the clypeus ; posterior ocelli nearly twice as far from 

 the eyes as from each other ; the cheeks a .little broader than the greatest 

 breadth of the eyes. Pronotum not depressed in the middle ; mesopleurse 

 swollen and armed with a long, acute spine. First abdominal segment 

 nearly twice as broad as long ; second ventral segment without a raised 

 area at the base ; the segments not strongly constricted ; fifth ventral 

 segment widely emarginate at the apex ; pygidial area about twice as 

 broad at the base as at the apex, gradually narrowed, twice as long as- 

 the greatest breadth. Head and thorax closely but not deeply punctured; 

 the enclosed area at the base of the median segment coarsely obliquely 

 striated, mesopleuree very coarsely striated ; abdomen subopaque, micro- 

 scopically punctured. Wings subhyaline, the apex and the radial cell 

 fuscous ; nervures fuscous ; first recurrent nen^ure received beyond one- 

 third from the base of the second cubital cell.

Type in Oxford University Museum. 



Nearly allied to C fefo.r Sm., but differs in the form of the clypeus, the 

 greater development of the spine on the mesopleuree and the much shorter- 

 petiole.

I am not aware that this species occurs within the boundaries of British. 

 India; the specimen from Tenasserim in the British Museum marked by 

 Bingham as a variety oi ferox is quite distinct. 

 The species closely allied to C. /ej'o.'r may be recognized by the following key 

 1. Clypeus with the lamina broadly rounded at 

 the apex and slightly porrect ; petiole 

 longer than broad . . . . . . . . C. ferox Sm.
