tc Die Bienen Afrikas nach dem Stande unserer heutigen Kenntnisse. I^y 



Chiyaka, Benguella, September ist, 1907; fl)'ing with Ceratina geigeriae at flowers of Geigeria spec. 

 (F. C. Wellman). 



General appearance like that of //. opacus Perez, but opacus has the mesothorax shining, with very 

 much larger and stronger punctures. H. geigeriae belongs to the group of U. quadrinotaius (Kirby) and 

 //. sexnotaius (Kirby) — a group characteristic of the Northern Hemisphere.

9. Black, the apices of the abdominal segments testaceous, the knees, tibiae and tarsi rufo-testaceous ; the 

 4 front-tibiae broadly yellow in front, the fore tibiae behind in the middle and the hinder in the middle all round 

 black; the wings clear hyaline, the stigma and nervures pallid testaceous. Flagellum of antennae brownish 

 beneath. The pubescence white. Tegulae testaceous-yellow. L. 7 mm. 



Clypeus shining, sparsely punctured; the front and Vertex closely, uniformly and rather strongly punctured, 

 as are also the mesonotum and scutellum. Metanotal area closely reticulated except round the apex. Apex of 

 clypeus transverse, the sides projecting into short blunt teeth, rounded at the apex. Third transverse cubital and 

 2nd recurrent nervures very pale, the former broadly curved outwardly; the 2nd abscissa of radius not much 

 longer than the ist, and clearly short er than the 3rd. Anal rima piceous; the segment at the sides rufous, the 

 hair also tinged with rufous. First abdominal segment minutely punctured. 



I am not sure but that this may be H. palUdipcnnis Sm.; but without an examination of the type it is 

 impossible to decide this from the description.
