5 . Nigra, capite, thorace, segmentoque mediano pallide aureo- 

 pubescentibus ; segraentis dorsalibus 4 basalibus apice fascia 

 siibargeiiteo-pubescente ; area pygidiali rufo-fu3Co-setosa ; man-

Long., c? $ , 13 mm. 



? . Eyes separated on the vertex by a distance slightly 

 exceeding the combined length o£ the second and third 

 joints of the flagellum ; the vertex very distinctly and rather 

 sparsely punctured. Front and clypeus clothed with very 

 pale golden pubescence, the clypeus very broadly triangu- 

 larly depressed at the apex, the margin subtruncate. Second 

 joint of the flagellum distinctls' longer than the third. 

 Thorax rather sparsely clothed with pale golden pubescence 

 and with longer pale fulvous hairs ; median segment not 

 more than half as long again as the scutellum, with a shallow 

 longitudinal impressed line, which is more deeply continued 

 on the posterior slope. Abdomen, including the second 

 sternite, minutely and closely punctured ; pygidial area 

 subtriangular, rather narrowly rounded at the apex. Basal 

 joint of the fore tarsus with seven rather slender spines. 

 Third abscissa of the radius half as long again as the second, 

 but scarcely equal to the distance between the recurrent 

 nervures on the cubitus. Third cubital cell on the cubitus 

 less than half as long as the second. 



(J . Seventh tergite not very broad, rounded at the apex ; 

 eighth sternite deeply and rather narrowly emarginate at 

 the apex. The galea is short in both sexes, not very much 

 longer than the greatest breadth, broadly rounded at the 

 apex ; the ligula is bi'oadly extended and bilobed ; second 

 joint of labial palpi no longer than the third. 



Hub. Uganda, Entebbe (C. G. Gowdey), June to January; 

 Mariba Forest, Chagwe, 3500-3800 ft. {S. A. Neave), 

 July. 



This species is easily distinguished from others of similar 

 colouring by the great distance between the eyes on the 

 vertex.

 toque mediano griseo-aureo-pubescentibus ; segmentis dorsalibus
