subhyaline, the apical region with a dark cloud ; nervures and stigma 

 dark, stigma small ; second s. m. broad, receiving first r. n. beyond the 

 middle ; legs red, the coxse and trochanters black, and the femora black 

 above ; anterior tarsi fringed with long hair ; middle femora short 

 and rather swollen, very shiny ; hind femora greatly incrassated, concave 

 beneath, with a sharp tooth on inner side beyond the middle ; hind tibiae 

 enlarged, subtrianguUr, with a broad, blunt, apical lamina, but no tooth 

 on inner side ; abdomen broad, with hair-bands on all the segments, apex 

 rounded, bright ferruginous. 



^ . — Legs black ; abdominal bands golden-fulvous. 



Hab. — Ekuiva Valley, W. Africa, 2 c^ 's, i ? , 1907, one of the males 

 at flowers of Geigeria (Wellman). The species is named after 

 Welvvitsch, the well-known African traveller, who collected bees in Angola 

 many years ago. By the clouded wings and other characters this closely 

 resembles N. nubecula, Smith, from Sierra Leone, but it differs from 

 nubecula by the dark mandibles (only slightly ferruginous in the middle), 

 the dark scape, the form of the scutellum, the dark tegulse, etc. The 

 face is broad, whereas in N. nubecula (of Ckll., Trans. Am. Ent. Soc, 

 XXXI, p. 322) it is narrow. In the form of the hind legs N. Welwitschi 

 resembles N. patellifera, Westw., except that the tibial process is shorter 

 and blunter. 



Nomia Wellmani, sp. nov. 



9. — Length 10 mm. or a little less, robust, black, the apex of the

 margins of the third to fifth segments with broad hair-bands of the same 

 colour, that on the fifth dense, those on the other two paler and thinner, 

 very thin on middle of third ; a little of the same hair at sides of second 

 segment ; all this giving an appearance just like that of the Australian N. 

 australica, Smith, as seen from a little distance. 



Head and thorax very densely rugosopunctate; face very broad, rather 

 thinly covered with coarse whitish hair ; antennae black, flagellum more or 

 less red beneath ; mandibles black, with long golden hairs beneath ;
