This species resembles closely jyalmarum, differing mainly in 

 color. The legs are all white in both sexes, and the mandibles of the 

 male are not long and horizontal as in jxdntarif/n. The male palpi 

 and palpal organs are like those of palniarxm, with the tibial hook 

 perhaps a little more slender. The female preserved in alcohol is 

 still more like pahnamm. The epigynum is of the same shape and 

 the markings in four large spots on the abdomen, like those of some 

 females of pahnaruin. The cephalothorax seems to be a little wider, 

 and the colors of the hairs of the whole body whiter than in ^>«/- 

 niaruin. 



A living male has the legs white, or a little greenish, with long 

 white hairs, those on the front legs longer than the diameter of the 

 leg. On the front of the leg and ])alpi are long, white hairs. The 

 sides of the cephalothorax and abdomen, and the under side of 

 the abdomen are white. The middle of the cephalothorax and abdo- 

 men ai"e light brown, covered with light, yellow hairs, through which 

 three or four dark spots show indistinctly. PI. XVIII, fig. 2.

Female 5'"'" and male 4'""' long. The living female has the legs 

 and palpi transparent white, and the claws black. The few spines 

 on the legs are black. The whole body is covered with light gray 

 or white scales, mixed with short, fine black hairs. The abdomen 

 has a row of indistinct, darker triangular spots in the middle and 

 oblique rows of small spots at the sides. PI. XVII, fig. 1. In alco- 

 hol the legs become dull yellow, and the rest of the body turns red 

 as in cestivalis, afterwards fading to a dirty yellow. The markings 

 of the abdomen become more distinct, and in some individuals form 

 four large, dark brown spots. Fig. 1/".
