A- CATALOGUE OF THE BEES OF CA
[April
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. ainericana Cr., La Jolla.
