triangle on the vertex, the posterior placed on the posterior declivity 

 of the head, closely behind the summit, and these distant not more 

 than the diameter of one from the anterior, in front of which the face 

 is deeply sulcated ; eyes very prominent and subglobose, the scape 

 less than one- third the length of the organ ; mandibles long and slender, 

 slightlycurved, broadestatthe base, whence theyimmediately attenuate, 

 their return in front equal throughout; the clypeus furnished between 

 the base of the antennae with a long flock of curling hair, and the 

 labrum with a pair of large round compressed tubercles. 



Thorax gibbous in front and at the scutellum, the latter transverse and 

 rounded; metathorax elongate, abruptly truncated at its apex, where 

 it is fringed ; mesothorax slightly corrugated in front on each side of 

 the two abbreviated parallel longitudinal central lines, the wrinkles 

 parallel with the suture that separates it from the prothorax: wings 

 subhyaline, their nervures dark brown, the radial nervure distinctly ex- 

 tending opposite and rather beyond the inner angle of the marginal cell, 

 where it terminates abruptly, the cubital nervure slightly undulated as 

 far as the insertion of the recurrent nervure, beyond which to the ter- 

 mination of the cell it is straight and inserted at half the length of the 

 first submarginal cell; legs castaneous, femora elongate triangular, 

 acuminated towards the apex, the outline beneath not perceptibly 

 rounded downwards; the trochanters of the four posterior not strictly 

 adhering, and projecting a little beyond the lower outline of the fe- 

 mora. 



Abdomen elongate, cylindrical, rather slender, the peduncle subquadrate 

 or rather subglobose (its ventral portion viewed laterally angulated 

 but hooked backwards), slightly fringed below its apex, not so bi'oad 

 as the following segment, which with the next is transverse, the ter- 

 minal segment very pilose.

This species was brought from Poonah, in the Bombay Presidency, 

 by Col. Sykes, and from Assam by Dr. Cantor, a wider range than 

 I know any other species to take. It considerably resembles the pre- 

 ceding. A comparison of the descriptions which I have purposely 

 made parallel will however show ample differences, although the 

 majority consist of minute particulars, the chief of which have been 

 already jiointed out in the observations on the former.
