Described from a single female specimen which flew into 

 a small laboratory dish of xylol on a table in the Natural 

 History Building, University of Illinois, Urbana, Illinois, 

 June 26, 1909, and which was captured and mounted by Mr. 

 J. D. Hood to whom the author is indebted for the specimen. 

 Also subsequently another female captured in a greenhouse 

 at Urbana, October 19, 1910, This specimen is decidedly 

 darker all over, colored like sinipe7inis and the wings are 

 more deeply fumated but otherwise I can not distinguish
