$ (5 . Frons strongly transrugose ; vertex arcuately and 

 occiput transversely rugose ; cheeks shorter than scape ; posterior 

 margin of head bordered. Second and third flagellar joints of 

 equal length and rather longer than first. Neck short, cen-

 furroAv. PropleursB diffusely punctate ; mesopleurse smooth 

 above, with three or four irregular rows of punctures below ; 

 metapleurse closely rugulose throughout, separated by a smooth 

 sulcus and a carina from the median segment, which is rather 

 densely but superficially punctate. Petiole transaciculate, a 

 little shorter than the remaining segments together ; base of 

 second segment feebly rugose, rest smooth aiid shining. Terebra 

 as long as, or very slightly longer than body, sheaths black, 

 broadly white-banded before apex. Hind legs with coxfe slender 

 and strongly trans-striate ; femora smooth and shining, bi-

There are also in the British Museum 5 5 $ , 2 (S cS ■, their 

 dimensions lying between those given above. 



Cameron states that the abdominal petiole is a little longer 

 than the rest of abdomen, but actual measurement shows it to be 

 shorter. He also gives the colour of the wings as fusco- 

 violaceous ; it is now brown ; possibly faded.
