BEES IN THE COLLECTION OF THE UNITED STATES 

 NATIONAL MUSEUM. 2. 



By T. D. A. Cockerell, 



Of the University of Colorado, Boulder. 



The present contribution deals principally with Asiatic bees, and 

 includes a number of new species collected by Dr. W. L. Abbott in 

 localities rarely visited by naturalists. Especially interesting are 

 those obtained at very high altitudes in the Himalayan region, be- 

 longing to a peculiar fauna, recently made known in part through the 

 work of the British Tibet expedition. 1 Doctor Abbott's collections 

 have long priority over those of the British expedition, but descrip- 

 tions of the latter have, in part, been published first.
