 A common species all summer. 

 Queens April 22, at Mt. Vernon, Va. (W. L. McAtee).

Worker April 28, on Maryland shore near Plummer Id. 

 June 14, at Rives, Md.

 Male July 27, on Maryland shore near Plummer Id. 

 Oct. 17, at Falls Church, Va. (J. Silver). 



The April 28th worker may be a small queen, but it is not im- 

 possible that it is a worker. I have heard of a record for this 

 species of March 10 for the queen, but have not been able to 

 verify it. If true, April 28th is not too early for workers to 

 appear. 



I have the following flower records : 



Prunus sp. Chrysopsis mariana 



Gentiana andrewsi Cirsium lanceolatum 



Mertensia virginica 



The gentian record is interesting as in order to get at the nec- 

 tar the bee had to pry open the end of the flower and once in, 

 back out. G. P. Van Eseltine, who collected the specimen, says 

 it had worked on several blossoms before he took it, and had 

 simply parted the corolla at the tip. 



8. Bremus auricomus (Robertson). 



This and the following species belong to the subgenus Bombias 

 and are none of them common in this region. 

 Queens April 6, at Plummer Id., Md. (W. L. McAtee). 

 Sept. 10, on Maryland shore near Plummer Id. 

 Worker July 24, at Four Mile Run. Va.
