Parauximus tardatus sp. nov. 



Male — Carapace dusky over light brown. Legs with somewhat obscure dusky 

 annuli over yellow. Labium and endites chestnut, pale across tips. Chelicerr dusky 

 chestnut. .Abdomen dark over sides, dorsally a pointed mark outlined in black from 

 base to middle, followed by a series of mesally connected chevron marks. \'enter 

 immaculate light grey with an angular extension from the dark of each side just in 

 front of the spinnerets, the two processes not meeting in the middle line. Lower 

 margin of the furrow of the chelicers bearing four large teeth and proximad of 

 these four smaller ones. Anterior median eyes very small, rather less than half the 

 diameter of the laterals, near their diameter apart and about the same distance from 

 the laterals. Posterior row of eyes straight; median eyes smaller than the laterals. 

 About their diameter apart and the same distance or a little less from the laterals. 

 Anterior laterals larger than posterior laterals and separated from them by about a 

 radius of the latter. Tibice and metatarsi I and II armed beneath with three pairs 

 of spines. 



Palpus as shown in plate 1, fig. _. Patella with a stout apophysis bearing distally 

 numerous spines. 



Type— M. C. Z. 377. Claremont. 



Readily distinguishable by the characters of the eyes and the structure of the 

 male palpus. 



Auximus pallescens sp. no v. 



Female — A species in appearance much resembling the preceding, though typi- 

 cally paler with the carapace and legs much more yellow. Sternum yellow. Labium 

 chestnut, pale across tip, the endites lighter; also distally pale. Abdomen colored 

 somewhat similarly to that of the preceding species, but the dorsal markings in the 

 type indistinct. The species is easily distinguished from the preceding by its much 

 larger anterior median eyes, which equal or nearly equal the laterals and obviously 

 exceed the posterior medians and which are separated from each other by rather 

 less than their radius and from the laterals by not more than once and a half their 

 diameter. Posterior median eyes separated by near once and two-thirds their diameter 

 and from the laterals by twice and a half their diameter, the laterals much larger. 

 Lateral eyes on each side separated by their radius or less. Lower margin of furrow 

 of chelicera armed with four teeth. TibijE I and II and metatarsi I and II each 

 armed beneath with three pairs of spines. Epigynum, apparently not quite fully 

 chitinized, shown in plate 1, fig. 3. 



Length 12.5 mm. Length of cephalothorax, 6 mm. Length of tib.-fpat. I, 5.7 

 mm.; of tib. + pat. IV, the same.

Auximus latescens sp. nov. 

 Female — Carapace pale chestnut tending to testaceous in posterior and lateral 

 regions. Legs testaceous to brown, the anterior ones often of slight chestnut cast. 

 Sternum pale chestnut and the endites and labium darker chestnut. Chelicera dark 

 chestnut or mahogany. The abdomen above is dark brown to blackish, with a pos- 

 teriorly pointed pale mark reaching from base to middle followed by a series of pale 

 chevron marks and on each side of it with usually three pale spots, which may be 

 more or less connected with it or sometimes a short light line each side; venter grey-
