THE DRASSID^

the length of the legs in the 

 two species, which is slight 

 in the females, is greater in 

 the males, the legs of calca- 

 rata being the longer. The 

 palpi of the males differ con- 

 siderably. In incerta (fig. 

 37) the tibia of the palpus 

 has a large process on the 

 outer side close to the tarsus and extending 

 along its edge a third of its length. In 

 calcarata (fig. 43) the corresponding process 

 is small and does not lap over the tarsus. 

 The coxae of the third and fourth legs of 

 the male calcarata have little processes on 

 the under side (fig. 42), one on the fourth 

 and two on the third. These do not occur 

 in incerta. It lives on plants like salta- 

 bunda (p. 14). 



Anyphaena rubra. — Larger than the other 

 species, with the legs shorter. The female 

 is about a third of an inch long, with the 

 abdomen longer and narrower than in incerta 

 or saltabunda. The opening of the air-tubes 

 (fig. 45) is farther forward than usual, twice 

 as far from the spinnerets as from the epigy- 

 num. The legs are comparatively short, 

 the longest, the fourth, being about as long 

 as the body. The maxillae are a little 

 widened at the end. The sternum is widest 

 at the second legs and narrows to a point 

 behind. The head is a little wider than 

 usual, and the whole appearance more like
