A CATALOGUE OF THE BEES OF CALIFORNIA. 



BY T. D. A. COCKERELL, EAST LAS VEGAS, N. MEX. 



In the Report of the Agricultural experiment station of the University of Cal- 

 ifornia for 1898-1901, recently published, Mr. Carroll Fowler gives an account of 

 the long-tongued bees of California. This is a very useful paper, so far as it goes, 

 and Mr. Fowler has been able to make important additions to our knowledge of 

 California bees. Unfortunately, however, the paper was prepared in 1899, and has 

 not been brought up to date ; consequently it omits numerous species recorded 

 since that year, and is not altogether modern in the matter of generic nomenclature. 

 It also omits several species published before 1899, and in a good many cases the 

 names of species are incorrectly spelled. In some cases, I am inclined to doubt 

 the identification of the species, but unless I have actual knowledge to the contrary, 

 I must for the present treat all published records as correct. 



The list here presented includes also the short-tongued bees of California, for 

 completeness' sake. It need hardly be said, that we know comparatively little about 

 California bees ; it is quite certain that any student who takes up this group in 

 California will find very numerous new species. The list now offered is intended 

 to be of service to such a student or students, as it is hoped that the publication of 

 Mr. Fowler's paper will have created an interest in the bees.
