received from Haverhill, Massachusetts. Pupation began May 31, 

 1894, the material having been received in March of the same year. 

 Say's type is no longer in existence, but a proxytype of this species 

 is in the Museum collection. There can be but little doubt that this 

 is the species Say had, as it is apparently the only one which occurs 

 in northern United States. That Kohl's species is a synonym of this 

 species (through the proxytype) there can be but little doubt, as the 

 male agrees exactly with the figure and description given by Kohl.
