Shannon described elongata from a single female specimen. 
There are now two male specimens in the National Museum col- 
lection which are presumably this species. One specimen is from 
Pullman, Wash., June 2, 1907 (collector unknown), and the 
other from Bellfountain, Ore., May 27, 1922 (A. L. Lovett). The 
above description of the male was drawn from the Oregon speci- 
men. 
Biology, habits, and immature stages. Unknown.
