Type of lacustris Cresson, in collection of the American Entomolog- 

 ical Society. From Berg Bay, June 10 ; Juneau, June 7, July 25 ; 

 Kodiak, July 20; Seldovia, July 21 ; Wrangell (H. F. Wickham) ; 

 Seward Peninsula (W. J. Peters) ; Sitka (Fur Seal Commission). 



This species is also common in Vancouver Island, B. C. 



The type of Bombus lacustris Cresson was submitted to me for 

 examination, together with other of Cresson's types of bumble bees, 

 by Dr. Henry Skinner, Curator of the American Entomological So- 

 ciety, and it is undoubtedly identical with the above species. What 

 Handlirsch describes as Bombus ternarius var. lacustris is probably 

 a different species.
