IIEMIPIMPL.V. 193 



subelevated longitudinally and discrete from the deplanate and 

 apically impressed clypeus ; mandibles not very stout, with the 

 subequal teeth apically infuseate and subobtuse ; cheeks distinctly 

 shorter than the basal breadth of the mandibles ; eyes very 

 slightly emarginate next the scrobes. Antennce black, two-thirds 

 the length of the body, setaceous ; scape entirely, and in tf 

 ilagellum beneath, rufescent ; joints cylindrical and not elongate. 

 Thorax bright red throughout, glabrous and very strongly nitidu- 

 lous, with very sparse dark pilosity on the metathorax; notauli 

 inconspicuous ; metathoracic areae entirely wanting, punctation 

 obsolete ; spiracles small, oval and directed towards apex. Scu- 

 tellum glabrous and not convex, with a few dark hairs. Abdomen 

 fusiform-cylindrical and broadest centrally, entirely dull black, 

 strongly punctate throughout, with the apical angles of the seg- 

 ments prominent ; basal segment distinctly longer than apically 

 broad in both sexes, slightly narrowed basally, centrally elevated, 

 strongly bicarinate and laterally scabrous ; the four or five fol- 

 lowing segments deeply incised transversely at their apical third, 

 the incision becoming laterally confluent with another, which 

 rises obliquely from the depressed base ; disc usually longi- 

 tudinally subcarinate ; basal ventral segments plicate ; cf valvulae 

 retracted; terebra black, slightly longer than the abdomen, with 

 the valvulse slender and pilose, spicula black. Legs short and 

 somewhat stout, red, with the hind pair alone entirely black ; 

 claws stout and strongly lobate, in $ hardly extending beyond 

 the pulvilli ; front tibiae simple, their calcaria curved. Wings not; 

 broad, strongly flavesceut, with their external margin broadly 

 infumate in both sexes ; radix, tegulse, costa and stigma testaceous; 

 areolet subpetiolate, oblique, and emitting the recurrent nervure 

 from near its apex ; lower wings with the first recurrent distinctly 

 postfurcal and emitting the nervellus tar below its centre; costa 

 of 6 fiavescent throughout. 



Length 14-17 millim.

This species is related to Hemipimpla testacea in the coloration 

 of the wings and to //. rugosa in that of the body and legs ; but 

 from both it is at once recognised by the distinctly postfurcal 

 recurrent nervure of the lower wings and more tumid basal 

 segment. Unlike H. testacea, both sexes have the postpetiole 

 bicarinate and the radius equally curved above the subsessile 

 areolet ; nevertheless I think no doubt can exist respecting the 

 correctness of the sexes of the former, as here described. My 

 description is drawn from one male and seven females in the 

 .British Museum.
