2. Mygale solstitialis. [56] 



PL 1, fig. 2. a. Eyes. b. Tropin, c. Abdomen viewed underneath. 



Description. Deep black ; cephalothorax with two indenta- 

 tions, cheliceres moderately large; abdomen with several im- 

 pressions above, and four yellow spots underneath ; membrane 

 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 carolinensis. 

 PI. 1, tig. 3. a. Eyes. 



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. W. ± 



Observations, This species was 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 

 Mygale solstitialis was taken from a male, which has the same 

 character. 



Habitat. North Carolina. 



4. Mygale gracilis. 



PL 1, fig. 4. a. Eyes. //. Righi palpus, with the maxilla. 



Description. Rufous; cephalothorax somewhat six-sided, 

 long and narrow; abdomen plumbeous, two nipples very long:
