NOTES ON THE COLEOPTERA OF BEITISH GUIANA.

In common with the other families of Insects from this British 

 Colony, very little is known as to the actual species of beetles and less of 

 their habits and life-histories. The only previous attempt to draw up 

 a list of the known species with which I am familiar is that by 

 Schombui'gk* ; scattered references to British Guiana Coleoptera are 

 widel}^ distributed through the world's entomological literature. 



The present paper is based on eight years' collecting and observations. 

 The collecting has been largely performed by myself, often during spare 

 time as opportunities have occurred and also whilst on official visits to 

 different parts of the Colony. The collection preserved in this laboratory 

 consists of about 2,300 specimens and 264 named species. The identifi- 

 cations have been made in nearly every instance through the agenc}- of 

 the Imperial Bureau of Entomologj^ ; a few have been performed in the 

 United States National Museum through the courtesy of Dr. L. O. 

 Howard, Chief of the Bureau of Entomology, U.S. Department of 

 Agriculture. 



I am indebted to the following gentlemen for specimens and in some 

 cases observations : — Messrs. K. Ward, K. Service, E. M. Morgan, 

 A. A. Abraham, L. D. Cleare, Jnr., C. C. Dowding, P. M. De Weever, 

 W. G. Claxton, H. W. B. Moore, and W. D. Cleary.
