The Bees of Massachusetts : Osmia and Sphecodes. 

 By JOHN H. LOVELL, Waldoboro, Maine. 



Since Professor Packard, almost fifty years ago enumerated 

 the described species of Bombns and Psithyrns of New Eng- 

 land, the Anthophila of Massachusetts have received very little 

 attention. There are, indeed, besides the two genera named 

 very few records of the bees of this State available. Some 

 months ago I received from Mr. Charles W. Johnson of the 

 Boston Society of Natural History a small collection of bees 

 belonging to the genera Osmia and Sphecodes for determina- 

 tion. A list of the species is as follows : 



SPHEGODES. 

 Sphecodes pithanus n. sp. 



5 . Length 10 mm. Head and thorax black ; abdominal segments 

 1-3 red, clouded with black, 4-5 black, 6 red. Head broad, face 

 thickly covered with short white hair; mandibles red, simple; an- 

 tennae black, the flagellum a dull red, joint 4 about as long as 3. 

 Mesothorax faintly shining, with small not well defined punctures ; 

 wings slightly tinged with reddish, the second submarginal cell nearly 

 quadrate, the first recurrent nervure enters the second submarginal 

 cell a short distance in front of the second transverse cubital ; stigma 

 and nervures fuscous, tegulae testaceous; legs black, tibiae and tarsi 

 red. Enclosure of the metathorax well defined, semi-circular, coarsely 

 reticulated. Abdominal segments 1-2 nearly impunctate, 3-4 finely 

 punctate at base, 5 all over ; basal segment largely black, 2-3 maculated 

 with black, 4-5 wholly black, 6 dark red. 



Brookline, Mass., July 18, 1878, collected by S. Henshaw. 

 In coloration this species most nearly resembles S. pimpinellae 

 Robt. ; from which, however, it is easily separated by its larger 

 size (S. pimpinellae is 7 mm. long), simple mandibles, venation 

 (S. pimpinellae has the second submarginal cell narrow, and 

 the first recurrent nervure unites with the second transverse 

 cubital), and by the color of the abdomen. The type is de- 

 posited in the Museum of the Boston Society of Natural His- 

 tory. 



Sphecodes johnsonii n. sp. 



$ . A little over 10 mm. in length. Head and thorax black ; abdo- 

 men red with black apical segments ; mandibles almost entirely black, 

 the extreme tips rufous, bidentate ; antennae black, the flagellum
