constricted basally, inconspicuously bicarinato l)efore its centre, 

 where are the spiracles ; terebra concealed and liardly extending to 

 anus. Areolet wanting ; radius and second recurrent nervures 

 strongly sinuate; nervellus intercepted below its centre. Legs 

 stout, with the femora iucrassate. 



Eange. Europe, Punjab, Assam. 



The lack of an areolet and of any distinct basal raetanotal 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 witli the common European Colpo- 

 trochia elegantida, Sehr., and it is obvious that he did not know the 

 present genus.

A handsome black species, with rich red markings. Head 

 and obliquely constricted behind the internally slightly 

 emarginate eyes, which do not ex- 

 tend to the base of the mandibles ; 

 occiput and frons closely punctate, 

 with the latter strongly carinate 

 between the scrobes ; face strongly 

 and evenly punctate, Avith griseous 

 pilosit}', not impressed nor discrete 

 from the apically broadly rounded 

 clypeus ; palpi and the centre of 

 the evenly bidendate mandibles 

 testaceous. Autenmv not shorter 

 than the body, black, strongly atten- 

 uate, with the scape entirely and 

 the flagellum beneath testaceous ; 

 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 ; mesouotum nitidulous, 

 sparsely and finely punctulate, hardly produced apically, with no 

 notauli ; mesopleurc-e nitidulous and distinctly punctate; metathorax 

 very finely punctate, lateral carinse distinct both above and below 

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

 complete ; petiolar wanting, longitudinally tricarinate apiciilly and 

 ]iot produced. Scutellum not large, niticUdous and subdeplanate, 

 deep red, with its long pilosity and transverse postscutellnm 

 concolorous. Ahdoinen distinctly longer than, and apically nearly 

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