XLIII. — Some Bees from British Guiana. 

 By T. D. A. Cockerell, University of Colorado, 



The bees of the Guianas were collected long ago, and many 

 of the commoner or more conspicuous species described by 

 the earlier authors. Thus it happens that a small collection 

 from this region will usually contain a number of the species 

 of Linnaeus, Fabricius, Olivier, Lepeletier, F. Smith, &c.^ 

 and one readily gets the idea that the fauna is well-known. 

 In later years, however, collections have been few, and such 

 authors as Vachal, Friese, Schrottky, Ducke, and others 

 have apparently bad little material from this part of South 

 America, The collection now reported on represents those 

 species, received by the Imperial Bureau from British 

 Guiana, which could not be readily identified at the British 

 Museum. I am greatly indebted to Dr. G. A. K. Marshall 

 for the opportunity to study them, and permission to retain 

 some duplicates, which will eventually go to the U.S. 

 National Museum. It will be seen that there are many 

 novelties, but they do not represent fundamentally new 

 types, but rather representative or local species of groups 

 well-known from other parts of South America.
