THE PHILIPPINE BEES OF THE FAMILY NOMADID^ 
By T. D. A. Cockerell, 
{University of Colorado) 
The Nomadidse 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 Halicttts. Those so far recog- 
nized may be separated thus: 
Genus NOMADA Scopoli 
Anterior wings with two submarginal cells 1. 
Anterior wings with three submarginal cells 4. 
1. Mesothorax of female black pervasor sp. nov. 
Mesothorax of female red, at least at sides 2. 
2. Front black, except along orbits attrita sp. nov. 
Front red 3. 
3. With a yellow spot at each side of second abdominal segment. 
makilingensis Cockerell. 
Without such yellow spots palavanica sp. nov. 
4. Males 5. 
Females 6. 
5. Third antennal joint short, little longer than broad.* . 
banahaonis Cockerell. 
Third antennal joint long, much longer than broad. 
mindanaonis Cockerell. 
6. With a conspicuous yellow spot at each side of second abdominal segment. 
exheredans sp. nov. 
Without such spots , 7. 
7. Mesothorax black, at most with a little red at sides 8. 
Mesothorax red, with at most a blackish discal shade 9. 
8. First abdominal segment with a broad red band; hind tibise red. 
concessa sp. nov. 
First abdominal segment black, with small red spots; hind tibiae black, 
with the ends red bakeri Cockerell. 
9. Hind margins of abdominal segments suffused with dusky; flagellum 
dull red beneath lusca Smith. 
Abdomen usually clear red; flagellum black mindanaonis Cockerell. 
* 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.
