I do not think there is room for doubt that the species above de- 

 scribed is the real erratica of Hentz, when one considers the abdominal 

 markings shown in his figure, in connection with his comments on 

 habits and the localities where he found it common. 



Hentz says concerning this species that it "was always found 

 wandering and never in holes; .... it was often seen, generally 

 running in the grass." This is a very common and widely distributed 

 species, found under stones and logs in the woods and especially in 

 grassy meadows. It is subject to much variation in size, though its 

 characteristic markings are rarely missed.
