228 Hentz^s Descriptions of the 



2. FILISTATA CAPITATA. . 



Description. Dusky brown ; eyes much elevated, cephalo- 

 thorax with a deep longitudinal impression, beginning above 

 the eyes and not reaching the base ; cheliceres not closely ar- 

 ticulated together ; abdomen and feet with short hairs. 



Observations. This species, communicated to me by Mr. 

 Thomas R. Button, was brought by him from Georgia, where 

 it inhabits crevices like Filtstata hibernalis. No females 

 were brought. It is strange that its cheliceres are not joined 

 together as in that species. The trophi in other respects cor- 

 respond entirely with it. 



Habitat. Georgia.

Genus. Lycosa. Latr. 



Characters. Cheliceres large, fo^ngs moderate; maxillce 

 short, parallel, cut obliquely at the tip ; lip short, slightly 

 emarginate at the upper edge, which is slightly narrower 

 than the base ; eyes eight, unequal, four small placed ante- 

 riorly in a straight or slightly curved line, two large placed 

 above the two external ones of the first line, two of tniddle 

 size placed further out towards the base and iiearly forming 

 a square with the intermediate ones ; feet, 4. 1. 2. 3. 



Habits. x\raneides making no web, wandering for prey, 

 hiding under stones and frequently making holes in the 

 ground in which they dwell, making at the orifice a ring of 

 silk, forming a consolidated entrance ; cocoon usually orbicu- 

 lar, often carried about by the mother, the young borne on 

 the back of her abdomen. 



Observations. The subgenus Lycosa is not variable in its 

 characters like Dolomedes. The lower row of eyes is 

 straight in some species and more or less curved in others, but 

 I could not avail myself of this to make any satisfactory sub- 

 division. The upper mammulae, it is true, are longer in 

 Lycosa lenta, but I found them to vary in length in others 

 so imperceptibly that I could not adopt any of the three fam-
