Bombus pleuralis Nylander. 



W'hitefish Point, Chippewa Co., July 24, a small worker 

 (Andrews 7). A very puzzling specimen. It looks like B. 

 Havifrons dimidiatus (Ashm.), but the malar space is much too 

 short. The general coloration is like B. consinnlis, but it can- 

 not be a melanic variety of that, the malar space being too 

 short ; it is also much too short for B. kirbycllns. The face is 

 too narrow and the malar space too long for B. affinis. The 

 specimen agrees well enough with Franklin's account of 

 B. pleuralis (though the light hair has none of the tawny tint 

 of PViese's figure), but plcnralis has not previously been 

 found nearer than Alaska. It is possible that a complete series 

 of all forms will indicate a new species or subspecies, but at 

 present there are apparently no grounds for separating the 

 insect from B. pleuralis. The abdomen is entirely black-haired 

 beyond the second segment. 



h". first abdominal segment icith black hair; malar space 

 short. 



Bombus terricola Kirby. 



Floodwood. Schoolcraft Co., July 8, 10, 25, three workers

 eleven workers (Andrews).
