THE DRASSID^ 



19 



of different sizes in different individuals and connected in 



different ways. The length is from a third to half an inch. 



The abdomen is wide across the middle and more pointed behind 



than in most species. The front middle eyes are about as far 



apart as in tibialis and nearer than in rubra. The mandibles 



are not much swelled in front. The legs of the male are longer 



than those of the female, with the first 



pair longest, while in the female the '^oOOo' 



fourth pair is longest. The male man- \^ 



dibles (fig. 62) are narrow at the end and 



hollowed on the inner edges as in tibialis, 



with a sharp ridge between the thick 



and the thin portions. The male palpi 



(fig. 61) have two processes on the outer 



side of the tibia longer than in rubra 



and shorter than in caiiadciisis. The tibia 



is a little widened toward the end and 



curved outward. 



Clubiona excepta. — A third of an inch 

 long and with very distinct gray mark- 

 ings on the abdomen. The cephalotho- 

 rax is light yellow brown, and the legs are more deeply 

 colored with yellow than in most species. The abdomen 

 is white, with sometimes a yellow mark on the front of ^5 

 the abdomen, and on the hinder half of the abdomen is a 

 middle row of gray spots and a row of larger transverse spots 

 on each side. The fourth legs are longest in both sexes. The 

 male palpi have the tibia longer than usual and patella and 

 tibia about the same length. The tibia has a small process 

 with two teeth (fig. 64). The tarsus is oval and narrow and 

 the palpal organ small. 



Trachelas ruber. — One-third of an inch long, with the cephalo- 

 thorax short and wide like Clubiona, and the deep orange-brown
