Thorell.] 498 [April 21, 



of the clypeus to the anterior lateral eyes is about half as great again 

 as their diameter. Mandibles rather narrower than the anterior thighs, 

 as long as the anterior patella?, straight, only convex at the very base, 

 dark rusty brown. Palpi dull yellowish brown, with the tibial joint 

 rusty brown, the tarsal joint blackish brown. Legs of a dark and dull 

 yellowish, or rusty brown; the first pair evidently (with the length of 

 its tarsus) longer than the second, which is but little longer than the 

 third; the length of the fourth pair is about the length of the first 

 and the tarsus of the fourth pair. , The tibiae of the first pair have 

 only one spine, at the apex of the under side; the tibiae of the second 

 pair have two spines at the apex, and besides, one small spine more 

 towards the middle, all on the under side. The tibiae of the third 

 pair have one spine above and two before and behind (besides three 

 pairs of spines beneath) ; the tibiae of the fourth pair have no spine 

 above. The abdomen is blackish, densely covered with fine ap- 

 pressed hair, which appears to be partly black, partly of a rusty 

 yellow, the abdomen thus showing a less distinct rusty yellow mark- 

 ing, consisting of a middle band along the anterior part of the back, 

 and a few transverse oblique bands on either side, behind. The belly 

 is blackish, covered with short appressed hair of a rusty brown color. 

 The vulva consists of a large, broad, almost egg-shaped fovea, which 

 is more depressed or excavated on the sides, thus showing in the 

 middle a broad, corneous, elevated, flat band or ridge tapering back- 

 wards towards the obtuse apex ; this ridge has a transverse depres- 

 sion near the apex; the anterior margin of the fovea is produced into 

 a backward directed, thick, transversely striated process, which lies 

 in an oblong excavation of the said ridge. Mamillae of a dusky 

 yellowish brown. 



Length of the animal, 9 millim. ; length of cephalothorax, 4.33 

 millim.; breadth of cephalothorax, 3 millim.; first pair of legs, 10.5 

 millim.; second pair, 9.5 millim ; third pair, 9.25 millim. ; fourth 

 pair, 12.5 millim.; patella and tibia of fourth pair, 3.75 millim. 



Of this species I have seen but one adult specimen, a female, 

 which was captured at Strawberry Harbor, July 28.
