"^^6 Cameron, Hymenoptera Orientalia. 



tarsi yellow, suffused with rufous ; the femora covered with 

 long, white hair. Wings hyaline, the nervures and stigma 

 fuscous. Petiole covered with long, white, soft hair; aluta- 

 ceous, the base closely longitudinally striated ; its under 

 part keeled down the centre and with a lateral keel between 

 it and the edge. In this latter point — in the under side of 

 the petiole being distinctly keeled down the centre — it 

 differs from C. taprobance.

This species is omitted entirely by Col. Bingham. It 

 comes into his section " C : median segment convex, 

 vertical, with a well-marked groove down the middle, 

 widening at apex into a deep A-shaped hollow " : and to 

 sub-section " a : Petiole long, gradually widening to the 

 apex, longer, never shorter than the thorax and median 

 segment united" ; but it can hardly be said to be "medially 

 with well developed, prominent lateral tubercles." The 

 petiole is distinctly longer than the head and thorax but 

 not longer than the other segments united ; its basal third 

 is distinctly narrowed, becoming gradually wider ; the 

 apical third is of uniform thickness. 



It has pretty much the same form and size and colour 

 of the wings as E. vishnu ; but differs altogether in the 

 colour of the legs, and in the form of the antennal tubercle, 

 which here is rounded at the top and has a long pedicle ; 

 while in E. vishnu it is much shorter, broader and 

 triangular at the top and with a short, broad pedicle.
