longer than the mesonotum and has the anterior margin 

 tran.svorse, with obscure transverse broken strite on tlie ante- 

 rior lialt and rather sparse punctures towards the posterior 

 margin. Mesonotum, scutellum, and mesopleurte very 

 coarsely punctured-rugose. Median segment very coarsely 

 reticulata, abruptly truncate posteriorly, with a transverse 

 marginal carina at the apex of the segment before the trunca- 

 tion, the surface of the truncation punctured-rugose. Abdo- 

 men shilling, sparsely punctured, the basal segment shorter 

 tiian the second, nearly as broad at the base as at the apex, 

 truncate at the bas<', with a low transverse carina above the 

 truncation. Seventh segment not incised at the apex; the 

 recurved spine of the hypopygium well developed. ISecond 

 abscissa of the radius shorter than the third by about one 

 quarter ; first recurrent nervure received just beyond the 

 middle of the second cubital cell.

This is very near E. dimidiaticornis, Bingh., but differs in 

 the colour of the head, prothorax, antenna?, and anterior 

 legs, 'i'he antennoe do not taper towards the apex as much 

 as in dimidiaticornis and are rather more widely separated at 

 the base. In dimidiaticornis the second abscissa of the 

 radius is fully as long as the third, and the second cubital 

 cell is less strongly produced towards the base on tiie cubitus. 

 The very long second abscissa of the radius chaiacteristie of 

 dimidiaticornis may possibly not be constant, as in the 

 female E. tricolor, Sm., there is certainly a tendency to 

 variation in this respect. The present species approaches 

 £. tricolor, Sm., more nearly in colour than dimidiaticornis. 

 But I feel some doubts as to the specific difference, and think 

 it quite possible that this will not prove to be more than a 

 local form.
