BEES COLLECTED BY NATHAN BANKS IN THE 
VICINITY OF THE PANAMA CANAL. 
By T. D. A. Cockerell. 
About one-half of the species collected are as follows: 
Melipona orbignyi phenax (Cockerell) 
Bella Vista, Aug. 7. I now conclude that M. orbignyi pen- 
ning si Ckll. was described from the male of M . phenax, the latter 
(from Ecuador) having priority of place. 
Melipona fulvipes triplaridis Cockerell 
Barro Colorado, Aug. 2. Larger and more robust than the 
type of triplaridis, but otherwise the same. 
Euglossa piliveniris imperialis Cockerell 
Barro Colorado, Aug. 15. Male 
Euglossa cordata (Linnaeus) 
Barro Colorado, June 20, July 25, Aug. 2 
Centris poecila Lepeletier 
Red Tank, June 30. Male. Gribodo (1893) described the 
male of C. poecila from Panama. 
Centris tarsata Smith 
Barro Colorado, July 24. Female. Agrees with one from- 
Guatemala. Friese considers it a form of C. lanipes (Fabricius). 
Centris inermis Friese 
Red Tank, June 30. Female. 
Exomalopsis zexmenioe Cockerell 
Mt. Hope, July 8. Female E. paitensis Ckll., 1926, from 
Peru, is perhaps too closely allied to E. zexmenioe and is probably 
to be considered only a southern race. Northward (Pt. Isabel ,,
