H. NovAEANGLiAE Robt. Tliis Small bee occurs in abundance 

 in the southern part of the State, and is supposed to fre- 

 quent only the flowers of Pickerel "Weed (Pontederia cor- 

 data) and its life is supposed to conform in a way to the 

 flower of this plant. I have examined thousands of blos- 

 soms in different parts of the Island in the past few years 

 and failed to find any of the bees, but I swept one specimen 

 in the swamp back of Schooner Head on August 28, 1936, 

 which is interesting, because there is no Pickerel Weed in 

 that swamp.
