Habitat . In the collection of the Museum of Compar- 
ative Zoology I have found 3 specimens with the label 
“Japyx subterraneus , Packard compared with type 
A.S.P.” from S. Ohio, Nov. 1874; from these specimens 
I have selected the female and the male here described. 
In the same Museum I have seen a specimen also labeled 
Japyx subterraneus from Lee Co., Va. (July 1879 Hub- 
bard). It agrees in the above characters with the speci- 
mens from Ohio.
