auricomus (Robertson), which, according to its label, was taken 

 near Boston many years ago. Neither he nor Professor Wheeler 

 has ever taken that species there, and no Boston specimens are 

 contained in the collections of the Boston Natural History Society 

 and of the Museum of Comparative Zoology. 



Psithyrus laboriosus (Fabricius). Five males were taken at 

 Forest Hills, about the middle of August, and one female in the 

 Stony Brook Reservation at flowers of Cephalanthus occidentalis, 

 July 21; also at Auburndale and Brookline (C. W. Johnson Coll.); 

 Sherborn (E. J. Smith Coll.). 



Psith3rrus ashtoni (Cresson). Auburndale and Brookline (C. W. 

 Johnson Coll.); Cambridge (S. Henshaw Coll.); Sherborn (E. J. 

 Smith Coll.). 



It is interesting to compare this list with other local faunas 

 farther north and south. At Waldoboro, on the coast of southern 

 Maine, Lovell^ did not find Bomhus impatiens, B. americanorum 

 and B. ajfflnis, three species which are rather abundant in the Tran- 

 sition Zone. On the other hand, two forms which are rather 

 Canadian or Boreal, B. borealis Kirby and B. ternarius Say, are 

 still to be found in southern Maine, while boreulis has never been 

 seen near Boston and ternarius is very rare there. Otherwise the 

 faunas of these two localities are very similar. 



From my own collecting experience and from what I have seen 

 in other collections, the bumble-bee fauna of the immediate vicin- 

 ity of New York City differs mainly from that of Boston in the 

 scarcity of B. terricola and the absence of B. ternarius, though both 

 these species are commonly found in the Catskills. B. ternarius 

 has never been taken near New York City; the nearest locality for 

 that species is Lake Marcia, Sussex County, N. J., where it was 

 collected by Dr. F. E. Lutz.- As to B. terricola, there are no New 

 York specimens in my own collection, nor in that of Mr. Wm. T. 

 Davis; I find, however, in the Brooklyn Institute of Arts and Sci- 

 ences two males from Essex Fells, Essex County, N. J. (A. S. 

 Nicolay Coll.) and, in the American Museum of Natural History, 

 two further specimens labeled "Astoria, Long Island." Two 

 species of the Austral Zone, B.fraternus (Smith) and B. auricomus

 '■ Bull. Amer. Mus. Nat. Hist., 35, 1916, p. 514. The specimen recorded as B. ternarius from 

 Staten Island in Smith's New Jersey List, is a worker of B. feroidus, though it bears a label in the 

 late Dr. Ashmead's handwriting "B. ternarius Say."
