Habitat. — Nova Scotia; Hudson's Bay territory; Maine; New 

 Hampshire; Colorado; Sierra Nevada, California. 



The types of the Grote and Walker species are in the British Museum, 

 and are the same as my desperata. Mr. Butler's reference was not made 

 until October 1891, after my revision was published. I had had the 

 species as dimmocM, and had so named it in the National Museum and 

 elsewhere. Mr. Grote's description misled me and induced me to cor- 

 rect a supposed misidentitication. The type is somewhat rubbed; but 

 the M of the s. t. line is distinct, not Avanting, as stated by Mr. Grote.

This seems a good species, almost midway between suhjuncta and 

 atlantica. I had not seen it before, the specimen in the Edwards col- 

 lection being erroneously named.
