9 . — Scutellum sometimes entirely black, but often yellow- 

 ish ; margin of the 5th abdominal segment fringed apically with 

 yellow hair. The female has been taken on Salix discolor, 

 April 30; 5\ bcbbiafta, May 13; Rhodora canadensis, May 28; 

 Aesculus liippocastanum. May 31 ; Rosa humilis, July 10, and 

 a variety of other flowers as Cormis alternifolia, Viburnum 

 alnifolium and Gaylussacia resinosa. 



£ . — All of the workers have the scutellum black, but the 

 apical margin of the fifth segment is fringed with yellow. 

 Collected on Rosa humilis, July 10; Aralia hispida, July 16; 

 and later on many midsummer and August flowers, as Solidago 

 bicolor, Gaulthcria procumbens and Vicia cracca. 



$ . — As remarked by Packard, the male might easily be 

 mistaken for a worker; but the clvpeus, which in the worker 

 is smooth, is densely bearded with yellow hair in the male; 

 the scutellum is sometimes black, but often with an admixture 

 of yellow hair. Found visiting the flowers of Aralia hispida, 

 July 15; Epilobium angustifolium, July 23; and later on Soli- 

 dago bicolor and Eupatorium perfoliatum.

9 . — the yellow pubescence on the scutellum is in some speci- 

 mens separated into two spots as in B. bifarius, which is prob- 

 ably only a variety of this species. Captured on Salix discolor, 

 April 30; S. bebbiana, May 12; Aesculus liippocastanum, May 

 31 ; also on Rhodora canadensis and Gaylusaccia resinosa. 



9 . — The workers are much smaller than the females and 

 the front is nearly black. Taken on Rhus typhina, July 10; 

 Solidago, September 8; also on Aralia hispida and Eupatorium 

 perfoliatum. 



$ . — The form of the male is more slender than that of the 

 worker. I have taken it only on Solidago bicolor.
