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 w^as 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.
