No type is designated by Kennicott. The specimens are referred to as coming 

 from Canij> Floyd and the Rocky Mountains in Utaii, and collected by C. Drexler 

 and C. S. McCarthy. The above two specimens are the only ones that fulfill 

 these reciuirements. Nos. tjH and 4953 are catalogued as coming from the 

 Rocky Mountains and doubtfully collected by Drexler. In view of this uncer- 

 tainty in regard to the Rocky Mountain si)ecimens, it seems best to restrict the 

 cotypes to the Camp Floyd specimens, whic;h is the better course, since it gives 

 the species a definite type-locality. Camp Floyd is considered the type-locality 

 by Miller and Rehn, Proc. Bost. Soc. Nat. Hist., XXX, p. 53, December, 1901.

No t3'pe is designated in the description. The species is based 

 upon specimens in the collection of the Smithsonian Institution, 

 frou) •"Nebraska" (including the present Nebraska, Wyoming, and 

 Dakotas), collected by Doctors Suckle^', Cooper, and Ibuden. The 

 following seven specimens answer to these re(juirements and are 

 undoubtedly the ones Kennicott had. This leaves the type-locality 

 rather indefinite. It is the general region of the present western 

 Nebraska.
