PHILIPPINE BEES OF THE GENUS NOMIA 
By T. D. A. Cockerell 
Of the University of Colorado 
The andrenid genus Nomia is widely distributed over the 
world, but is much more numerous in species in the Eastern 
than in the Western hemisphere. The species show such diverse 
characters that authors have at different times proposed to 
divide the genus into several genera and subgenera. It is doubt- 
fully expedient, however, to recognize more than one genus, 
though most of the names proposed may properly be used in a 
subgeneric sense. The type of the genus, as Meade-Waldo has 
shown, is the Asiatic Nomia curvipes of Fabricius. This has 
colored tegumentary bands on abdomen, postscutellum unarmed, 
and the hind femora of the male greatly swollen and sharply 
toothed beneath. It may be considered typical of a group which 
in the Philippine fauna includes N. thoracica, N. longitarsis, N. 
lusoria, N. strigata, and N. iridescens ; but none of these has the 
hind femora of the male as in curvipes. In N. thoracica these 
femora are swollen, but not toothed beneath. 
Hoplonomia Ashmead resembles true Nomia, but has a bi- 
dentate process, or two teeth, on the postscutellum. The type is 
N. quadrifasciata, a Philippine species. 
The following key will facilitate the separation of the Philip- 
pine species:
