cuted during a long residence there, it was published in 1925 in Am- 

 sterdam. The Bonnes were in frequent correspondence with the 

 Bureau at Washington, and on their way home to Holland in 1919 

 they spent several months here studying the great mosquito collections 

 in the National Museum with Dr. H. G. Dyar. 



British Guiana. — As we have pointed out under the head of the 

 West Indies. British Guiana has practically the same entomological 

 problems as Trinidad, the fauna and flora of Trinidad being essentially 

 that of northern South America, as it is rather an island promontory 

 than a removed island. A number of British collectors visited British 

 Guiana in times past, and the English collections, especially those of 

 the British Museum of Natural History, contain a great deal of 

 material from that country. Many interesting observations on points 

 relating to the biology of tropical insects were made there. 



Official economic entomology was not taken up in this country 

 until 1 912, when Mr. G. E. Bodkin, a young Englishman, was ap- 

 pointed Government Economic Biologist. He passed through Wash- 

 ington in December of that year, on his way to his post, and I met 

 him afterwards at the conference of the Imperial Bureau of En- 

 tomology in London in 1920. Mr. Bodkin was a well trained man 

 and did admirable work. He remained in British Guiana, publish- 

 ing mainly on entomological subjects, until 1922, when he went to 

 Palestine. During the term of his British Guiana residence be pub- 

 lished many important annual reports, and, from 1913 to 1923, 27 of 

 his articles were reviewed in the Review of Applied Entomology. 

 He was succeeded in office by Mr. L. D. Cleare who had previously 

 been associated with him. A sound entomological article by Mr. 

 Cleare is reviewed in the first volume of the Review of Applied 

 Entomology (1913), but apparently he did not begin to publish 

 extensiA^ely until after he assumed the position vacated by Mr. 

 Bodkin. 



Probably the main entomological problems of British Guiana center 

 around the cultivation of sugar cane, and the majority of the papers 

 published by Bodkin and by Cleare relate to some phase of insect 

 damage to this crop. The large sugar-planting companies of that 

 colony, notably Messrs. Curtis, Campbell & Co. and Messrs. Booker 

 Brothers, McConnell & Co., Ltd., carried on investigations for a 

 time independent of the colonial government. Mr. John J. Quelch 

 was for some years Curator in the Museum at Georgetown, and 

 afterwards worked on a group of these sugar estates on the con- 

 trol of the Diatraea borer and other pests. I am informed by Pro- 

 fessor Ballou that Mr. H. W. B. Moore was discovered when a
