stripe of various shapes, bordered with brown or gray (fig. 487). 

 The whole body is covered with fine hairs, and there are often 

 long white hairs in rows on the cephalothorax. The cribellum 

 is large for the size of the spiders and can generally be plainly 

 seen just in front of the other spinnerets. The calamistrum 

 is not so easy to see, but it covers about half the length of 

 the fourth metatarsus. The peculiarities of the species of these 

 spiders are more strongly marked in the males. The mandibles

of both sexes are long and a little curved forward at the ends 

 (fig. 476), but in the males they are sometimes so long that the 

 distance from the ends of the mandibles to the top of the head is 

 as great as the length of the cephalothorax, and the lower ends 

 are turned forward at a sharp angle with the upper part. The 

 mandibles of the males are curved apart in the middle, and they 

 have at the base a short tooth projecting forward (fig. 477). 

 The palpi of the males have a process on the tibia, usually 

 near the base, on the end of which are two spines (fig. 478).
