constricted basally, inconspicuously bicarinate before its centre, 

 where are the spiracles ; terebra concealed and hardly extending to 

 anus. Areolet wanting ; radius and second recurrent nervures 

 strongly sinuate ; nervellus intercepted below its centre. Legs 

 stout, with the femora incrassate. 



Eange. Europe, Punjab, Assam. 



The lack of an areolet and of any distinct basal metanotal areoe, 

 coupled with the subsessile abdomen, will instantly distinguish this 

 conspicuous genus. The type of that recently erected by Cameron 

 agrees to a remarkable extent with the common European Colpo- 

 trochia elegantula, Schr., and it is obvious that he did not know the 

 present genus.

 black and obliquely constricted behind the internally slightly

 all the joints very short, with the 



first flagellar hardly longer than the second. Thorax much broader 

 than head, black, and with long grey hairs ; mesonotum nitidulous, 

 sparsely and finely punctulate, hardly produced apically, with no

 very finely punctate, lateral carinse distinct both above and below 

 the very elongate spiracles; basal area minute, triangular and sub-

 concolorous. Abdomen distinctly longer than, and apically nearly 

 as broad as, head and thorax, very strongly nitidulous, with the
