Seven specimens are in the Museum collection : Sharon, New York, 

 July 23 (Meske); Arizona, Colorado (J. B. S.) ; Nevada County, Cali- 

 fornia (through C. V. E.). The Nevada County specimens bear the red 

 label 307, and are darker than the others, most nearly resembliug the

 1874. Grt., Can. Eut., vi, 215; Diantlmcia. 

 1881. Grt., Can. Ent., xiii, 129; Mamestra. 



Like vicina, but rather paler, more reddish in ground color with some- 

 what wider wings; and antennre of male rather thicker. 



Expands 28 to 32™™ (1.12 to 1.28 inches). 



Habitat. — Texas, Colorado, California, Washington, Vancouver. 



Detailed description seems useless, as it would be simply duplicating 

 the description of vicina. The only differences have been pointed out. 



Four specimens are in the Museum collection: Vancouver (J. B. S.) 

 and Texas, October 7 and 19 (C. V. E., from Belfrage material). 



Mr. Grote gives August, September 11, and November as dates of 

 specimens received from Sanzalito, California.

 tion.
