324 NOTES ON BUMBLEBEES 



Dakota. The presence of this species in Montana is not sur- 

 prising when the records of its distribution in North Dakota, 

 Saskatchewan, and Alberta are considered. 



2. Brenms affinis (Cresson). Virginia, one queen and seven 

 workers; West Virginia, two workers and two males; Illinois, one 

 male. Franklin lists this species from Virginia and West 

 Virginia in his geographical table, but it is not clear from his 

 remarks whether it had actually been found there. In 1919, 

 the writer expressed the view this species would be found in 

 Illinois. The existence of this male confirms this supposition 

 and makes a total of sixteen Bremidae now recorded from 

 Illinois. 



3. Bremus affinis var. novae-angliae (Bequaert). West Vir- 

 ginia, one male; Grandfather Mt., North Carolina, one male, 

 September 11, 1908, 2500-3000 feet altitude (Z. P. Metcalf). 

 The occurrence of this variety in these two states is interesting, 

 as the variety was formerly only known from Massachusetts and 

 New York. 



4. Bremus borealis (Kirby). Volga, South Dakota, two 

 workers. 



5. Bremus vosnesenskii (Radoszkowski). Montana, one queen. 

 This is a very small specimen. 



6. Bremus perplexus (Cresson). Illinois, one worker. Listed 

 by myself, in 1919, from Illinois on the basis of the record fur- 

 nished me by the late Mr. O. S. Westcott. This is the first 

 specimen of this species I have seen from Illinois. 



7. Bremus ter^iarius (Say). Montana, one queen. This 

 species has been repeatedly confused with B. huntii (Greene) in 

 the western states, but the present specimen is without doubt 

 ternarius. The fact that ternarius is also known from the 

 Dakotas, Saskatchewan and Alberta helps ex))lain tlu> distri- 

 bution in the present instance. 



8. Bremus frigidus (F. Smith). Thunderhead Mountain, 

 6,000 ft. altitude, Blount County, Tennessee, one female, 

 August 4, (H. A. Pilsbry). This species presents a very scattered 

 distribution and is evidently one of the rar(>r forms throughout 

 its rang(;.
