Semrsoides hcspera sp. nov. 



Male — Carapace, sternum, labium and endites and legs yellowish. C'helicerae 

 darkened distad bv the black teeih of the rastellum. Abdomen yellowish beneath; 

 light brown above, with three longitudinal rows of short, black, transverse marks. 

 Chelicerr long and rather slender, extending almost directly forward, not at all 

 geniculate, the lower teeth of rastellum stout. Anterior row of eyes procurvcd in 

 such manner that the line tangent to the lower edges of the median eyes passes 

 through or near the centers of the laterals; lateral eyes with diameter twice that 

 of the medians; median eyes their diameter apart. Anterior and posterior lateral 

 eyes equal or very nearly so, separated by less than lialf their radius. Posterior 

 median eyes nearly of same size as the anterior medians from which separated by 

 their radius, closer to the posterior laterals. Tibia I in male with spur or process; 

 strongly spined ; a series of long, stout spines along each side, fewer smaller ones 

 beneath, typically a short, oblii|ue row of four close-set and especially stout spines 

 at the ectoventral corner of the distal end. Metatarsus I with a strong angle, or 

 process, at middle of the ventral edge. Palpal organ as shown in pi. 1, fig. 1. 



Length, 10 mm. Length of cephalothorax, 5 mm. Length of tib. + pat., 1.5 mm.; 

 of tib. + pat. IV, 5.5 mm.

 I miiiiKihius nigrellus sp. nov. 



Fftnalr — Carapace dusky chestnut to nearly black. Sternum solid black. Labium 

 and endites black or blackish excepting across tips. Legs dusky brown, the femora 

 darker, blackish. Abdomen above and laterally blackish brown, the background black 

 lightened by numerous minute yellowish dots; venter mesally immaculate black. 

 Anterior median eyes their diameter apart, once and a half as far from the laterals. 

 Posterior row of eyes but little longer than the anterior; median eyes nearly twice 

 their diameter apart, and almost two and a half times their diameter from the 

 laterals. Area of median eyes wider behind than in front and longer than wide. Tibia 

 I unarmed. Anterior metatarsi well spined beneath. Tibia IV with four spines 

 beneath, these in a longitudinal line with an extra one at distal end. Tibir III and 

 IV with a small spine at the base above, in this differing from the other known 

 North American species. Lower margin of furrow of chelicerx armed with two 

 teeth. Epigynum a plate subcordate in outline with a median longitudinal band ex- 

 tended laterad on each side behind. 



Length 6 mm. Length of tib. -f pat. I, 3 mm.; of tib. - pat. IV, the same.

Pnrauximui gen. nov. 



Resembles .Auximus in eye characters, but eyes of both rows nearlv e(|uidistant. 

 It differs in having the lower margin of the furrow of the chelicerr armed with 

 eight teeth, instead of four or five, of which the most distal instead of the most 

 proximal is largest; upper furrow with three teeth of which the median is largest. 

 .\ notable feature of the genus is that the patella of the male palpus, at least in the 

 genotype, bears a stout apophysis.
