1920] Bequaert — Hymenoptera Collected near Boston 9 



this identification was undoubtedly erroneous. It seems very 

 probable that these Woods Hole specimens belonged to B. affinis 

 var. novoc-anglioE. 



In drawing up the following list of the Bombidae known to occur 

 within a radius of twenty miles from Boston, I have perused, besides 

 my own data, collected during the summer of 1919, information 

 kindly given to me by Prof. Wm. M. Wheeler and Messrs. N. Banks, 

 C. W. Johnson and E. J. Smith. 



Bombus terricola Kirby. This is perhaps the most common 

 species of bumble-bee at Forest Hills; also at Auburndale (C. W. 

 Johnson Coll.) and Sherborn (E. J. Smith Coll.). 



Bombus affinis Cresson. The typical form is common at Forest 

 Hills where it visits, among others, the flowers of Ceanothus ameri- 

 canus; also at Auburndale and Dedham (C. W. Johnson Coll.); 

 Sherborn (E. J. Smith Coll.). 



Bombus bimaculatus Cresson. Common at Forest Hills; also at 

 Cohasset (C. W. Johnson Coll.) and Sherborn (E. J. Smith Coll.). 



Bombus impatiens Cresson. Forest Hills; also Auburndale, 

 Dedham, Brookline, and Cohasset (C. W. Johnson Coll.); Sherborn 

 (E. J. Smith Coll.). 



Bombus ternarius Say. Mr. E. J. Smith, who has taken a few 

 workers of this species at Sherborn, believes that it is very rare 

 near Boston. Professor Wheeler informs me that in many years 

 collecting he has never seen it at Forest Hills, though he has com- 

 monly taken it at Colebrook, Conn. 



Bombus perplexus Cresson. Wollaston (Mus. Comp. Zool.); 

 Auburndale and Arlington (C. W. Johnson Coll.) ; Sherborn (E. J. 

 Smith Coll.). 



Bombus vagans Smith. Forest Hills; also from Auburndale, 

 Dedham, and Boston (C. W. Johnson Coll.) ; Sherborn (E. J. Smith 

 Coll.). 



Bombus fervidus Fabricius. This is a common species at Forest 

 Hills; also at Auburndale and Cohasset (C. W\ Johnson Coll.); 

 Sherborn (E. J. Smith Coll.). 



Bombus americanorum (Fabricius) = Bombus pennsylvanicus 

 Franklin. Rather scarce near Boston ; I have taken it at Lexington 

 and Mr. E. J. Smith has it from Sherborn. 



Bombus separatus Cresson. Sherborn (E. J. Smith Coll.). 



Mr. E. J. Smith informs me that he has also seen a female of B.
