The living males, fig. \g, have the front legs very dark brown, 

 except the tarsi, which are a little lighter. The other legs are trans- 

 parent white, cephalothorax and abdomen dark and reddish brown, 

 mixed with shining, greenish white scales, and sometimes a little 

 copper red around the eyes. There is a white stripe the whole length 

 of the body, each side, and across the front of the head below the 

 eyes. The maxillae and mandibles are dark brown, and the palpi are 

 the same color, except the tarsi which are light yellow ; sternum and 

 under side of abdomen dark brown. Some males show indistinctly 

 dorsal markings of the abdomen, like the female. 



The female resembles cestivalis, but is longer in proportion to its 

 width and has the front legs stouter. The abdomen is usually nearly 

 twice as long as wide. Fig. 1, The cephalothorax is flattened 

 above from the front eyes two-thirds its length backward, in both 

 sexes, fig. 1«, while in (estivalis it is slightly arched upward. 



Ill the males, the front legs are, as usual, longer and stouter than 

 the others and are made very conspicuous by their dark color. 

 The mandibles of the male are lai'ger than those of the female, and 

 more or less turned forward, according to their length. In some 

 males the mandibles are only a little longer than those of the female, 

 and in these the patella and tibia of the front legs are not much 

 longer than the femur. Others, usually larger spiders, have the man- 

 dibles nearly as long as the cephalothorax and extending forward 

 horizontally, the maxillae are longer, and the first pair of legs have 

 the patella and tibia one and a half times as long as the femur. 

 Fig. le. Fig. Ig shows the mandibles of the common length. 



The epigynum has two small anterior openings and a large, wide 

 notch behind, half-way between the anterior openings and the trans- 

 verse fold. 



The male palpus has the tibia as wide as long, and the patella a 

 little longer. The tibial hook is as long at the joint itself, thin and 

 curved inward a little at the end. The tube of the palpal organ is 

 long and curved around the end of the bulb, the point resting in a 

 groove turned obliquely outward on the end of the tarsus. Figs.
