I have not seen this species, which appears to be allied io agilis, 

 but may be distinguished by the striation of the posterior slope 

 of the median segment, which is punctured in agilis.

The description of this species is insufficient, but I do not 

 think 'it is identical with any Indian species.

These are undoubtedly sexes of one species. I have seen 

 Cameron's types.

 Long. 8 mm. 



§ . Head and thorax opaque, very closely microscopically 

 punctured; clypeus broadly rounded at the apex; the front 

 with a distinct longitudinal sulcus extending to the anterior 

 ocellus ; eyes a little further apart on the clypeus than on the 

 vertex,. separated on the clypeus by a distance slightly exceedino- 

 the length of the scape and the two basal joints of the flagellum 

 combined ; posterior ocelli a little further from each other tha.n 

 from the eyes, separated from the eyes by a distance equal to the 

 diameter of one ocellus. Second and third joints of the flagellum 

 subequal. Median segment slender, shining and microscopically 

 punctured ; the dorsal surface nearly as long as the mesonotum 

 and rather strongly narrowed to the apex ; the median sulcus 

 broad and distinct, without a median carina, distinctly inter- 

 rupted between the dorsal and posterior surfaces, with a minute 

 triangular raised area projecting into the sulcus at the base of 

 the segment ; the posterior slope minutely punctured, without 

 strife. Abdomen minutely, closely, and evenly punctured, both 

 on the dorsal and ventral surfaces. Second abscissa of the 

 radius less than half as long as the first transverse cubital
