Type. Male, No. 54986, U. S. National Museum. 
Type locality. Melrose Highlands, Mass.

One specimen ‘‘on flowers of Solidago’’ collected Sept. 13, 
1914, by C. H. T. Townsend. 
This species would go into the genus Pseudonesia by extend- 
ing the limits of that genus to include species with male front 
wide in relation to the head width, and the abdomen more 
strongly pollinose. The species townsend is less brilliantly blue 
than pusilla, genotype of Pseudonesia.
