valvula ventrali apicali subangusta, poene carinata, lateribus dense 

 nigro spinosis. 



Elongate, black, dull, nearly glabrous, except for the fine, almost im- 

 perceptible greyish, pile which covers the whole insect ;head, pro- and 

 mesonotum, dark sanguineous red; the first with the clypeus, labrum, 

 a spot on the face and another over the ocellar region, black ; sides of 

 the head posteriorly clothed with longish hairs ; labrum with a dis- 

 tinct central incision. Clypeus with its anterior margin slightly 

 sinuate, antennas with the joints of the flagellum a little more than 

 twice as long as wide ; pronotum posteriorly angulated, its surface 

 in front clothed with a few exserted hairs, scutellum considerably 

 raised and narrowly flattened down the centre, its sides subconcave ; 

 post-scutellum widely grooved down the centre, wings dark brown, 

 with purple reflections. 2nd submarginal cell wider than long, 3rd 

 narrower than the 2nd, constricted towards the upper margin, which is 

 about half the length of the lower, external nervure very convex, 

 almost angulated. Legs with the posterior metatarsi as long as the 3 

 following joints taken together, claws nearly straight, toothed towards 

 the apex, propodeum rather long, with traces in 1 specimen of trans- 

 verse rugosities at the sides and the apex ; abdomen long, clothed with 

 a dull greyish pile ; 6th segment rather deeply emarginate in the 

 centre ; 8th pointed, slightly convex, but hardly carinated, its sides 

 densely fringed with thick spine-like hairs, intermingled with finer 

 ones, armature with the upper processes of the stipites very long and 

 slender, slightly converging at the apex ; lower pairs curved, hairy, and 

 somewhat spatulate, outer lateral processes curved, long, narrow and 

 hairy, slightly dilated at the apex, longer than the upper processes. 



Long. 13, 14 m.m.

 These are exactly like our British specimens of this 

 species. The form of the 8th ventral segment is very 

 peculiar, being very wide and subtectiform ventrally, each 

 side produced into a pale, translucent wing, the surface 

 clothed with black hairs, the centre much raised into a 

 strong carina, and the apex emarginate ; when the segment 

 is in its normal position, the lateral wings are scarcely 

 visible. I believe this species is probably the bifidus of 

 Morawitz, and the h&reticus Tournier.
