Prosthesima depressa, new sp. 



Plate III, figures 8, 8a. 



A smaller species than atra. Female, 6™™ long. The head is 

 much smaller than in atra and the eyes larger and closer together. 

 Plate III, fig. ft. The cephalothorax and abdomen are black. The 

 first and second legs have the tarsus and metatarsus pale yellow, the 

 rest of the legs black except a pale spot on the outside of each 

 femur. The third and fourth legs have the tarsus and metatarsus 

 pale, the tibia black at the distal end, the leg becoming lighter from 

 this point to the base. Underneath, the coxae are darker from 

 behind forward. 



The epigynum has the openings at the sides, farther forward, and 

 the ridges over them thicker and shorter than in atra, and the two 

 little depressions in front appear to be wanting, fig, 8«.

This spider is about 8 or 10™"' long, a little smaller than Gnaphosa 

 conspersa which it resembles in foi'm and habits, but from which it 

 is easily distinguished by its colors. The cephalothorax is black at 

 the sides and has a whitish stripe in the middle. The abdomen is 

 black at the sides with a bright white stripe in the middle that 

 extends from the front end about two-thirds its length. At the 

 hind end of the abdomen, just over the spinnerets, is another white 

 spot. The legs are dull black turning to brown in alcohol, as does 

 the cephalothorax. The under side of the abdomen is dark at the 

 sides and light in the middle. 



The eyes cover about half the width of the head. The two rows 

 are nearly equal in length, the hinder only a little the longer. Seen 

 from above, both rows appear straight. PI. iir, fig. 7. 



The maxillae are widened at the end, the outer corner sharp and 

 the inner rounded off down to the lip. Fig. 7«. 



The male is much smaller than the female but similarly marked. 

 The male palpi are small. The patella and tibia are short, and the 

 tarsus is as long as both together. The process on the tibia is slender 

 and about equals the tibia in length. It is on the outer side, show- 

 ing indistinctly from above. It is slightly forked at the tip. The
