OF NEW ENGLAND. 117 



Compared with B. vagans, the legs are very similar ; the 

 first tarsal joint is however not so broad arid convex 

 without, while the remaining joints are much the same. 



In a nest of twenty-three specimens collected by Mr. 

 Putnam at Bridport, Vt., the scutellurn was invariably 

 yellow. Most of these specimens have the fifth abdomi- 

 nal ring red, so that there are three instead of two red 

 rings. In nearly every case the front of the head was 

 darker than above described, since by their pollen gather- 

 ing habits the longer yellow hairs easily rub off. It is a 

 common and widely distributed species ranging according 

 to Cresson from Maine to Utah, Puget Sound and Arctic 

 America, and southward to Pennsylvania. 



I append the description of three additional species 

 described from Connecticut and New York by Mr. 

 Cresson. 



BOMBUS FERPLEXUS Cresson. 



" Male. Head black, with a tuft of pale hairs in front 

 below the antennae ; vertex yellowish. Thorax bright 

 honey-yellow. Wings hyaline, apical margins faintly 

 clouded. Legs black ; base of femora beneath yellowish. 

 Abdomen with the three basal segments bright honey-yel- 

 low, the third segment having a slight admixture of black ; 

 remaining segments black. Beneath black, slightly mixed 

 with yellowish. Length 8 lines. 



Female and ivorker not seen. 



One specimen, Connecticut. (Coll. Norton.) 



This species closely resembles B. hudsonicus, but the 

 form of the body is more elongate arid not so compact as 

 that of the latter species, and the color is much brighter." 



BOMBUS BIMACULATUS Cresson. 



" Male. Head black, mixed with yellowish on the face 

 and vertex. Thorax honey-yellow. Wings sub-hyaline, 

 slightly stained with yelloAvish. Legs black, clothed with 

 yellowish hairs, especially on the femora beneath. Abdo- 

 men with the whole of the first segment above, and the 

 second, except a few black hairs on the middle, and a 

 round black spot on each side, pale honey-yellow ; the 

 fourth segment mixed with black and yellow ; the third
