Type.— C?ii. No. 24001, U.S.N.M. 



Described from one female labeled " Oswego, N. Y., July 17, 1896 " ; 

 two males reared at the (xipsy Moth Laboratory, Melrose Highlands, 

 Massachusetts, from cocoons, but without locality data, and one 

 male labeled " Champaign, 111. 16331." I have seen some additional 

 material of this species: In the National Museum there is one other 

 specimen from the C. F. Baker Collection, which was taken in Ala- 

 bama under No. 1967. The Cornell University Collection contains 

 specimens from Slaterville, Caroline, McLean, and Eock City, New 

 ^ork; and fet. Hilaire, Quebec, Canada. In the collection of the 

 Boston Society of Natural History there is a single specimen taken 

 by Mr, C. W. Johnson at Chester, Massachusetts; and in material
