present, species begins at the apex of the radial cell and 

 thence narrows rapidly. 



Hemipepsis heteroneura, sp. n. 



2 • Fulva ; alis flavo-hyalinis, venis ferrugineis. 

 Long. 14-17 mm. 



$ . Clypeus transverse at the apex, minutely punctured ; 

 a few large punctures before the apex, each bearing a long 

 fulvous hair. Interantennal prominence not well developed, 

 second joint of the flagellum half as long again as the third, 

 the latter more than three times as long as its apical breadth. 

 Eyes separated on the vertex by a distance about equal to 

 the combined length of the two basal joints of the flagellum, 

 the posterior ocelli nearly twice as far from the eyes as 

 from each other. Anterior angles of the pronotum broadly 

 rounded, scutellum and postscutellum convex, not com- 

 pressed laterally. Median segment rounded, gradually 

 sloped, with an obscure longitudinal impressed line, the 

 dorsal surface very delicately and. indistinctly trausversely 

 striated. Abdomen shining, but not highly polished, the 

 sixth tergite thinly covered with long fulvous hairs ; im- 

 pressed transverse line of the second tergite situated beyond 

 one-third from the base. Spines of the fore tarsi very short 

 and. slender ; hind tibiae strongly serrate and with a few 

 short spines ; tarsal ungues with two teeth. Radial cell 

 obliquely truncate at the apex, third abscissa of the radius 

 about as long as the first and second combined, first re- 

 current nervure received just beyond three-quarters from 

 the base of the second cubital cell, second at one-third 

 from the base of the third cubital cell. Discoidal spot very 

 distinct. Submedian cell much longer than the median ; 

 cubitus of the hind wing almost interstitial. 



Hab. Uganda Protectorate, Western Ankole, 4500- 

 5000 ft. (S. A. Neave), October 1911. 



This is a rather aberrant species owing to the position of 

 the first recurrent nervure ; but in other characters (such as 

 the presence of a discoidal spot, the bending of the cubitus 

 beyond the second transverse cubital nervure, and in the 

 bidentate ungues) it is an undoubted Hemipepsis. Other 

 species showing the same aberrant character in the neuration 

 are H, hilaris, Sm. (Pompilus h.), H. similipicta, Sauss. (Prio- 

 cnemis s.), H. hildebrandti, Sauss. (Priocnemis /*.), and 

 H. nesarchus, Schulz, to which latter the present species is 

 more nearly related.
