Some Neiv Genera and Species of Hymenoptera. 221 



above slightly, below more broadly obliquely truncated. Ventral 

 surface thickly covered with longish siivery pubescence. The basal 

 slope of the first abdominal segment broadly in the centre, its apex 

 and that of the second and third are narrowly black ; the ventral 

 segments are tinged with rufous. The clypeal fringe is pale golden ; 

 tegulae yellow ; the head and thorax are more thickly covered with 

 white hair than in the female. 



The third antennal joint in the male is as long as the scape, in the 

 female it and the second are as long as it together; in the male 

 the hinder ocelli are separated from each other by a slightly 

 greater distance than they are from the eyes, in the female by a less 

 distance. 



Col. C. T. Bingham informs me that there is a male of this species 

 in the British Museum from Damaraland. 



Cerceris melanospila, sp. nov. 



Eufous ; the front from shortly behind the ocelli, the face below 

 and on either side of the keel, the clypeal and facial sutures, the 

 lower third of the outer orbits, the thorax except the apex of 

 pronotum, tegulae, tubercles, and the scutellums, the basal slope 

 of first abdominal segment, a line in its centre reaching to the fovea, 

 a triangular mark on the base of the second segment in the centre, 

 the base of the third, fourth and fifth segments narrowly, a line in 

 the centre of the third, the fourth except for a square mark on the 

 sides at the apex, a large mark on the fifth roundly narrowed 

 to the apex, not reaching to the apex of the segment and the 

 ventral segments, broadly, irregularly, black. Wings hyaline, 

 tinged with fulvous, the apex smoky ; the stigma and ne.rvures 

 fulvous. ?..

Antennas rufous ; the third joint shorter than the scape and about 

 one-fourth longer than the fourth. Clypeus roundly convex, distinctly 

 projecting beyond the cheeks, the apex roundly narrowed to the 

 middle, which is transverse, with a slight depression in the centre. 

 Front and vertex closely, distinctly punctured ; the ocelli separated 

 from the eyes by double the distance they are from each other. The 

 upper two-thirds of the antennal keel distinctly margined, pale 

 yellow. Pro- and meso-notum w T ith scutellums closely rugose ; the 

 metanotum more Coarsely rugose, its area at the base obliquely, at 

 the apex transversely striated. Mesopleurae rugose, the pro- and
