Araneides of the United States. 225 



sent me the male and the female, also, with a correct sketch of 

 both sexes. It inhabits that State and was found in cavities 

 under ground, under rotten wood, &<c., in the month of May. 



PI. VIII. Fig. 2. Dysdera interrita. a. Its trophi. h. It? eyes. 



Genus. Pylarus. Mihi. 



Characters. Chelieeres smcdl, fang very shorty maxillcB 

 slightly inclined over the lip, long and slightly rounded at 

 tip ; lip tapering J half as long as the maxillcB ; eyes six, 

 equal, in three pairs, two in the middle, and two each side, 

 placed diagonally on a comirhon elevation, nearer the anterior 

 edge ; feet, first, second and fourth pairs suhequal, third short- 

 est, penultimate joint of the first pair armed with hooks in 

 the male. 



Habits. Araneides sedentary, forming a silken tube in 

 crevices of walls, with a few threads spreading from the ori- 

 fice unto the edge of the crevice, the spider watching near 

 the entrance with its three anterior legs extended out. 



Observations. This subgenus which was first confounded 

 by me with Dysdera, differs from it by the small size of its 

 chelieeres, and the position of its eyes. By the habits of the 

 spiders which compose it, it bears close affinity to Segestria, 

 but the position of its eyes is reversed. It is obvious that as 

 this is not Segestria, and cannot be referred to Dysdera, it 

 must constitute a new subgenus. 



1. PYLARUS BICOLOR. 



Description. Cephalothorax piceous ; abdomen bluish- 

 black ; first and second pairs of legs blackish, hairy, third and 

 fourth piceous. Male piceous ; abdomen with the base and 

 sides paler ; feet with few hairs, penult joint of the first pair 

 crooked and with two strong spines, the antepenult with about 

 four strong bristles on each side. 



Observations. This spider, which is very common in Ala- 

 bama, makes its tubular habitation in the crevices of walls, 

 commonly waiting near the orifice with its three first pairs of 

 legs directed forwards. Its silken tube spreads out on the out-
