Note. — Since the foregoing paper was printed, I have seen the Canadian Entomologist for 

 December, 1889, and learn therefrom (Vol. XXI, p. 238) that Dr. Henry Skiuuer has received 

 examples of Epipsodea caught in Assiniboa, about 325 miles west of Winnipeg ; and with them 

 one of the var. Brccei, mentioned as var. sine-ocellata.
