? . Clypeus truncate at tlie apex, vatlier broadly depressed 

 on the apical mar^'in, with two minute teeth on each side. 

 Head finely and closely punctured ; eyes separated on the 

 vertex by a distance not quite equal to the length of the 

 second joint of the flagellum ; antennae slender and rather 

 long. Thorax closely and not very finely punctured ; 

 median segment strongly longitudinally striated, the sides of 

 the segment more finely obliquely striated, the surface of tlio 

 posterior truncation finely transversely striated. Py;tiidial 

 area triangular, not elongate, shining, with a few scattered 

 punctures. Comb of the fore tarsus long and slender ; the 

 long spur of the hind tibia almost as long as the basal joint 

 of the hind tarsus. Radial cell long, rather narrowly rounded 

 at the apex ; third cubital cell about as long as the second, 

 both on the cubitus and on the radius. 



(^ . Seventh dorsal segment broadly rounded at the apex ; 

 eighth ventral segment shallowly emarginate, the angles 

 produced into distinct teeth. 



IJab. N.E. Rhodesia, Niamadzi River, near Nawalia, 

 2000 ft. (S. A. N<ave), August; Mid Luangwa Valley, 

 2000 ft. {8. A. Neave)y July ; Upper Luangwa Valley 

 {S. A. JSeave), August. 



This differs from strigatus in colour, in the much finer 

 sculpture of the tliorax, in tiie lesser distance between the 

 eyes, and in the long and slender antennas.
