A male specimen was taken at West Point on June 20, 1905 
(H. S. Smith), and a female at Glen, August 17, 1906, on So- 
lidago (H. S. Smith). This species and the following are evi- 
dently quite rare in this state. The specimens before me differ 
from Fox’s description in having the scutellum black instead of 
yellow, but inasmuch as this is a variable character in this genus 
I have unhesitatingly placed them here. The female I am not so 
sure of, as it has a very different appearance, the head being much 
larger relatively and more quadrate looking from above. How- 
ever, as the female of this species is heretofore unknown, and on 
account of the spined gula I feel comparatively safe in placing it 
here until more specimens are taken.

So far this species has been found only in the northwestern 
corner of the state and uncommonly. These were taken at Glen, 
on August 20 (H. S. Smith).

Apparently inhabits the entire state, as I have specimens from 
Lincoln, West Point, Crawford, and Glen. It flies from May to 
August on flowers of Solidago and Mentzelia. Some of the spec- 
imens have the scutellum yellow and others entirely black.
