56 Hentz^s Description of the 



2. MYGALE SOLSTITIALIS. 



Description. Deep black ; cephalothorax with two inden- 

 tations, cheliceres moderately large ; abdomen with several 

 impressions above, and four yellow spots underneath ; mem- 

 brane between the joints white ; third pair of legs with the 

 third joint short and crooked ; feet hairy, 4. 1. 2. 3. A large 

 species. 



Observations. One specimen only (a male,) was found in 

 July, wandering on the ground. The character, derived from 

 the third pair of legs, does not seem to be a mere sexual dis- 

 tinction, as Mygale Carolinensis^ the next species, has the 

 same peculiarity, and the description was taken from a female. 



Habitat. Alabama.

3. MYGALE CAROUNENSIS. 



Description. Brownish, very glossy ; cephalothorax with 

 two slight impressions near the base ; abdomen blackish, not 

 glossy ; third joint of the third pair of legs very short and 



crooked ; feet 4. 1. 3. 2. 



Observations. This species was communicated to the au- 

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

 Carolina, a promising young naturalist, snatched by consump- 

 tion 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 de- 

 scription of Mygale solstitialis was taken from a male, 

 which has the same character. 



Habitat. North Carolina.
