 without hair-bands ; head subtriangular, the eyes long and 

 converging below; malar space present, but very short; 

 clypeus long, flattened, dullish, with very minute ])uacture3

 the sides of the clypeus as narrow grooves ; antenna black, 

 short, ordinary ; vertex dull; mesothorax very shiny poste- 

 riorly, anteriorly with a more sericeous surface ; pleura with 

 long hair ; area of metathorax broad, dullish, with a minutely 

 striatulate surface, its margin evident but rounded ; tegulae

 large stigma and the nervures piceous; lower section of b. n. 

 strongly bent about its middle and falling some distance 

 apicad of t.-ni. ; t.-m. not or hardly oblique, slightly bowed 

 outwards ; two submarginal cells, the first about or nearly 

 twice as long as the large second, the latter receiving both 

 the recurrent nervures, the second nearer to its apex than the

JJab. Hinterland of Benguella, Jan. o, 1908 (F. C. 

 Wei/ man). 



Tidcen with other bees {Coslioxys bengnellensi's &c.) at a 

 small |)atch of flowering (yompositaj, Ollionna and Geigeria. 

 No pollen had been collected. This is not a genuine Du' 

 fourea^ nor is it a Uahctoides ; I believe it should be regarded 

 as the tyj)e of a new genus, derived from the African Halic- 

 tines, but I shouhl like to see more material, and especially 

 the male sex, belore proposing a generic name. 1 have 

 given the characters of the venation which separate it from 

 the real Dufourea.
