 long as in most species of the genus. Eighth sternite 

 rounded at the apex. I overlooked this species in my recent 

 revision of the Ethiopian TacJiytes.

 witli dull silver pubescence which extends on to the front. 

 Eyes separated on tlie vertex by a distiince slightly exceeding 

 the length of" the second joint of the flagellum ; the vertex 

 c1o>ely and finely punctured. Thorax and median segment 

 rather sparsely clothed with erect whitish hairs ; median 

 Segment nearly twice as long as thescutellnm, witii a shallow 

 longitudinal sulcus. Second sternite very closely and rather 

 finely punctured ; eighth sternite truncate at the apex, the

 apex. Basal joint of fore tarsus with four spines. Second 

 and third abscissae of the radius subequal, shorter than the 

 first ; the third cubital cell on the cubitus extending a little 

 beyond the apex of the radial cell. Galea broader than long. 

 ? . Eyes separated on the vertex by a distance equal to 

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

 basal joint of the tore tarsus with four spines ; second sternite 

 more finely punctured than in the male ; third sternite
