median segment less tlian two-tliirds as long as the meso- 

 notum ; second sternite shining, with large scattered 

 punctures. 



J*. Eyes separated on tlie vertex by a distance slightly 

 exceeding three-quarlers ol" the leugtij of the second joint 

 of the flau^clluin ; clypcuis very broadly rounded at tlic apex. 

 Apical teriiites and sternites as in basilica. Second ventral 

 segment finely and closely punctured. The pubescence of 

 the al)domen is jialer than in observabilis.

The median segment is shorter than in basilica and 

 ohservabilift, and the eyes are further apart ou the vertex. 

 The third and fourth joints of the flagellum are slightly 

 arcuate beneath in the male.

(J. Niger; mandibnlis in medio, tegulis apice, calcnribus ungui- 

 culisque fusco-ferrugineis ; alis subhyaliuis, venis fuscis ; capite 

 albo-piloso, thorace griseo-piloso, segmentis abdominalibus apice 

 anguste brunneis, segmentis dorsalibus dense aureo-pubesceutibus ; 

 segmento ventrali octavo apice fortiter emarginato. 



Long. 16 mm. 



(? . Eyes separated on the vertex by a distance slightly 

 exceedius; three-quarters of the length of the second joint 

 of the flagellum ; clypeus broadly rounded at the apex ; 

 maxillary palpi si x -join ted ; labial palpi four-jointed, the 

 two basal joints long and slender, the second about equal in 

 leny,th to the second joint of the tlagellum, the first longer ; 

 puncturation of the vertex indistinct. Median segment 

 nearly twice as long as the scutellum. Second sternite 

 shining and rather strongly punctured in the middle, much 

 more finely and closely on the sides. Seventh tergite rather 

 broad, subtruncate broadly at the apex ; eighth sternite 

 M'idely and rather deeply emarginate, the apical angles 

 produced.

 of Mt. Elgon, 3700 ft. (S.A. Neave), August ; Mbale- Kurai 

 Road, South of Lake Salisbury, 3700 ft. (S. A. Neave), 

 August. 



This is near velox, but has the seventh tergite broader, 

 and the eighth sternite veiy different. The eyes are much 

 further apart on the vertex than in observabilis or neavei. 

 From 7nira it may be distinguished at once by the different 

 number of joints in the palpi, and from rhodesiana by the
