Observations. This species w^as communicated to the author 

 by the late Mr. Levi Andrews, of Chapel Hill, North Carolina, 

 a promising young naturalist, snatched by consumption from his 

 numerous friends, and to the memory of whom this tribute is 

 due. The character derived from the third pair of legs is not 

 a sexual one, as this was a female, and the description of 

 3Iygale solstitialis was taken from a male, which has the same 

 character. 



Habitat. North Carolina.
