below ; the vertex weakly punctured. Face closely, distinctly, 

 somewhat strongly punctured. Thorax shining, closely, distinctly 

 punctured ; the median segment more closely and strongly than the 

 rest ; the base of the propleurae is smooth, impunctate above. 

 Abdomen closely punctured, more strongly than the thorax ; the 

 apices of the segments are shining. Areolet 4-angled ; the trans- 

 verse cubital nervures meeting in front ; the recurrent nervure is 

 received clearly beyond the middle. The amount of black on the 

 apex of the abdomen and of red and white on the legs probably 

 varies. 



As I have stated, I.e., the affinities of this species are with 

 P. melanospila, Cam. (Annals S. Af. Mus., Y. 1906, p. 115). The 

 two may be separated thus : — 



Breast black ; the four anterior coxse, trochanters, and 



the greater part of the rest of the legs yellowish ; the 



hind femora red ; the apex of abdomen not black . . . . melanospila, Cam. 



Breast rufous ; the four anterior legs for the greater part 



and the hind femora black ; the apex of abdomen broadly 



black heliophila, Cam.

HYMENOBOSMINA, D.T. 

 Hymenobosmina pomonell^, sp. nov. 



Black, the antennal scape and. legs red ; mandibles obscure 

 testaceous ; the teeth black ; palpi pale yellow ; the anterior coxae 

 pale yellow, the posterior black ; wings hyaline, iridescent, the 

 nervures and stigma black. $ and $ . 



Length 7 mm. ; terebra 2-5 mm. 



Face and clypeus closely, uniformly punctured, covered with 

 silvery pubescence ; the front and vertex are similarly punctured, 

 but not quite so strongly. Temples obliquely narrowed. Thorax 

 closely punctured, the mesonotum more strongly than the scutellum 

 or pleurae. The basal keels of the areola are more distinct than the 

 apical ; they are straight, oblique, and unite at the base ; there is 

 a large basal lateral area, the keels being broadly rounded ; beyond 

 this is a large, somewhat triangular area, not clearly bounded on the 

 inner side ; there is an indication of a small petiolar area. Tegulae 

 yellow. 



As this species is not quite typical, I give a generic description 

 of it. 



Clypeus not at all separated from the face ; its apex broadly
