bb. Abdomen gray, with two dark spots at the anterior 

 end, often with several .small dorsal spots on a line with 

 these, and sometimes a short median band. 



e. Band on the cephalothorax deeply notched in front 

 of the dorsal groove. L. kocliii. 



cc. Band on the cephalothorax with the margins en- 

 tire. L. frondicola. 

 bbb. Abdomen very light gray, with a dark central-toothed 

 band running its entire length. L. arenicola. 

 bbbb. Abdomen black, mottled with buff; no distinct fig- 

 ure. L. jyolita. 

 The median band of the cephalothorax is often obsolete in L. 

 polifa and arenicola, so they are inserted twice. 

 L. carolinensis, AValck. (PI. XV, figs. 6. 6a.) 



Gray or dark l)rown above, without any distinct pattern on the 

 cephalothorax. A short black median band on the forepart of the 

 abdomen. Under side of abdomen, sternum and coxae, deep black. 

 The male has two rows of light dots on the abdomen reaching from 

 the middle of the black central stripe to the posterior extremity. 

 Length of female, 25 mm. 



The deep black color of the under surface, and the unhanded 

 legs, serve to distinguish this species from the next, while its large 

 size separates it from the other members of the genus. 



I have occasionally found this spider under stones, but most 

 frequently at the bottom of the tube-like holes which it digs in 

 meadows or on the edges of woodland. Females with egg-bags 

 have been taken in their burrows during the la^t week of August; 

 while others, apparently full sized, had not deposited their eggs by 

 the middle of September. Males have been taken running on the 

 ground in grass fields. This species has been observed in Philadel- 

 phia and Chester County, Penn., and also in Mercer County, in the 

 western part of the State.
