THE PHILIPPINE BEES OF THE FAMILY NOMADIDA# 
By T. D. A. COCKERELL 
(University of Colorado) 
The Nomadide are represented in the Philippine Islands by 
species of Nomada Scopoli, a genus very widely spread over 
both hemispheres. The Philippine species are all small and 
look like small wasps. They are parasitic, presumably in the 
nests of the various species of Halictus. Those so far recog- 
nized may be separated thus:

* The second joint is very small and partly hidden in the apex of the 
first, so it is possible to mistake the third for the second.
