mostly dark, but with some yellow hair on the sides. Venter dark on 

 each side of the middle line, but with sides of apical margins of most 

 of the segments fringed with yellow hairs. 



Wings. — Only moderately stained with brown ; the fore pair some- 

 what the lightest across their middle portions. 



Legs. — Coxae, trochanters and bases of femora with considerable 

 light yellow pile, at least on their lower sides ; tibiae dark. 



Worker. — Much like the queen ; face and occiput often almost en- 

 tirely dark, with only a slight admixture of yellow hairs ; the anterior 

 part of the dorsum of the thorax and the middle of the scutellum often 

 with an admixture of black hairs ; wings lighter than those of the 

 queen, subhyaline. 



Male. — Unknown. 



Dimensions. — Length: queen, about 15 mm. ; worker, 9^ mm. to 

 12 mm. Spread of wings : queen, about 33 mm. ; worker, 20 mm. to 

 26 mm. Width of abdomen at second segment : queen, about 8| mm. ; 

 worker, 4| mm. to 5^ mm. 



Habitat. — I have records of this species from New Mexico 

 only. They are as follows : Rio Ruidoso, White Mountains 

 (from 6500 to 6800 feet altitude) , the type specimens ; Cloud- 

 croft, several queens in the collection of the American Ento- 

 mological Society. This species is very closely allied to B. 

 vagans and thorough collecting may prove that it should be 

 considered as only a subspecies. 



Bombus (Bombus) bolster! new species. 

 Types. — Described from four queens (cotypes) and five 

 workers (cotypes), all from Newfoundland (Bay of Islands, 

 Little River, Humber River near Deer Lake), deposited in 

 collections as follows : Massachusetts Agricultural College 

 (one queen and one worker), Museum of Comparative Zo- 

 ology (one queen and one worker), American Entomological 

 Society (one queen and one worker), United States National 

 Museum (one queen and one worker) and the private collec- 

 tion of Judge P. G. Bolster, Boston, Mass. (one worker). 

 Mr. Bolster collected the specimens and I name the species 

 in his honor. 



Pile rather long and of medium texture. Head dark ; thorax yel- 

 low, with a very broad black interalar band, the anterior part of the 

 dorsmn also, in the case of the queefi, with a more or less strong ad- 

 mixture of black hairs ; dorsum of abdomen with the first two segments 

 yellow, third and fourth black, fifth yellow and sixth black ; corbicu- 

 lar fringes black. Malar space rather long.
