Superfamily Argiopoidea 



a little more than one fourth inch in length. The cephalothorax 

 and legs are reddish, the latter darker toward the tips; the ab- 

 domen is black with a broad white stripe on each side, reaching 

 from the base to beyond the middle, where the two are connected ; 

 there are some indistinct pale chevrons above the black spinnerets; 

 the venter is black with a large basal area pale. 



This species was described from California. 



Pcecilochroa minuta (P. mi-nu'ta).— Of this species only 

 the male has been described. It measures one sixth inch in 

 length. The cephalothorax is uniform reddish yellow; the legs 

 and palpi are a trifle paler; the abdomen is black with short white 

 hairs and some longer black ones at the base; the sternum is 

 yellowish; the venter with a pale streak on each side. 



A single specimen was described from Texas. 



Genus ZELOTES (Ze-lo'tes) 



The cephalothorax is ovate, very much narrowed in front, 

 and furnished with a median furrow. The anterior eyes are 

 near together, in a procurved line, and equal in size or with the 

 median eyes a little smaller. The posterior eyes are in a straight 

 or nearly straight line, which is a little or not at all wider than 

 the anterior line; the eyes of this row are equidistant or frequently 

 with the median eyes farther from the lateral eyes than from each 

 other. The clypeus is wider than the anterior eyes. The upper 

 margin of the furrow of the chelicera is furnished with one or 

 with two teeth, the lower margin is unarmed or furnished with a 

 small tooth. 



This is the largest genus of the family Drassidae, including 

 one hundred and fifty described species; fourteen of these have 

 been found in our fauna of which the following are among the 

 more common ones. 



Zelotes ater (Z. a'ter). — The female is nearly one third 

 inch in length; the male is smaller. This is a deep glossy 

 black species without markings; sometimes, especially in the 

 young, the tarsi and the lower side of the abdomen is yellowish 

 brown. 



This is our most common species of this genus and is widely 

 distributed. 



Zelotes rufulus (Z. ru'fu-lus). — The length of the body varies
