SOME OBSEEVATIONS ON THE GENUS BOMBUS, etc., IN WALES. 



BT C. L. WALTON, M.SC. 

 (Adviser in Agricultiiral Zoology, University College, Bangor.) 



During the period 191-3-16, and again from 1919 to 1921, I had a 

 wide experience of the counties of West and North Wales, and thus had 

 ample opportunity of observing the havoc wrought by " Isle of Wight " 

 (Acariue) disease among the Hive Bees of these areas. Also, through 

 F. W. L. Sladen's book, I became interested in the Humble-Bees, their 

 distribution, work, etc. I noted whole districts depleted or cleared of 

 Hive Bees, and wondered whether the absence of pollinators would be 

 felt in any way by farmer, gardener, or fruit-grower. I liave not, so far, 

 been able to satisfy myself that such has been the case, and believe that 

 the work is effectually performed by the Wild Bees. During Jvily and 

 August 1919, I began to make notes on the flowers worked by the various 

 Bombi to be met with (chiefly during a three-week holiday period in 

 Mid-AVales). Such notes were continued subsequentl}^ with a view to 

 obtaining some data as to the work of the various species of Humble- 

 Bees to be found in West and North Wales. I wished to bring out, if 

 possible, any differences that might exist in the type of floAvers visited 

 by the various species throughout the season, and to form some idea as to 

 their value to Agriculture and Horticulture; or to prove, on the other
