Long., ¢ 2,13 mm. 
9. Eyes separated on the vertex by a distance slightly 
exceeding the combined length of 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 distinctly 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. 
3. 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 broadly extended and bilobed ; second 
joint of labial palpi no longer than the third. 
Hab. 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.
