Type locality, Homer, 111., April 24, 1909 — a large series, mostly females. 

 Parafypes, Urbana, 111., April and June; Algonquin, 111., April and June; 

 Claremont, N. H., October 16, 1915 (R. P. Dow) ; Tifton, Ga., October 16, 

 1896; Opelousas, La., March; London, Ont. (ex. coll. Hough). 



The Hough specimens are labeled dentipes, as is also one of 

 the Algonquin specimens from Dr. Nason. It is highly probable 

 that this species is the one that has been recorded as dentipes from 

 North America.
