 anticis, tarsisquc intermediis posticisque apice fusco-ferrugineia ;

Long. 13 mm. 



? . Cijpens broadly truncate at the apex, finely and closely 

 punctured on the basal half; the apical lialt deflexed, shining, 

 with large scattered ])unctures. Vertex very closely micro- 

 scopically punctured ; the eyes separated on the vertex by 

 a distance slightly exceeding the length of the second joint 

 of the flagellum ; front and the base of the clypeus clothed 

 with very short silvery pubescence, which is only visible in 

 certain lights. Thorax minutely and closely punctured ; 

 median segment granulate, as long as the mesonotum, the 

 Sides and ajjcx ot the segment striated. Second and third

The type is a male, not a female, and is a true Tachysphex. 

 The wings are of a darker fuscous than in any other small 

 black Ethiopian species of the genus known to me. Eyes 

 separated on the vertex by a distance equal to about twice 

 the length of the second joint of the fiagellum.
