way between dorsal eyes and A. S. E. Mandibles small, vertical. Sternum twice as 

 long as broad ; coxse I separated by less than width of lip. Leg I not much longer 

 than others, much thickened ; ^-3 spines under tibia, the basal of inner' series at basal 

 third ; 2-2 stout spines under metatarsus I ; metatarsus IV spined only at tip ; all legs 

 with few hairs; no patellar spines; leg IV very slender. Epigynum shows two 

 rather widely separate small holes and behind a group of five dark marks. Length, 

 4.5 mm. 



One specimen from Edinburg, Texas. 



Eremattus, new genus. 



Allied to Jl/arpissa, but differing in having but one (or none) spine under tibia 

 I, this very short and near tip. Cephalothorax long and flat; eye-region occupying 

 about two fifths of length, rather broader behind than in front ; legs short and stout, 

 leg I thickened ; anterior coxfe separate by less than width of lip, metatarsus and 

 tibia III and IV with a few slender spines ; abdomen rather elongate, and depressed ; 

 leg I fringed beneath. 



T)'pe. — Marpissa albopilosa Banks. 



Probably also includes Iciiis piraticus Peck. 



Pellenes calcaratum, new species. 



Cephalothorax much like P. ccvcahitu Htz., a median pointed black stripe, and 

 lateral black stripes not reaching hind margin ; eye-area dark brown, concave behind. 

 Clypeus yellowish brown ; mandibles black. Abdomen black above, margined with 

 white, a pair of round white dots near middle (sometimes united) and a median spot be- 

 hind. Sternum and coxk pale yellowish ; venter pale, with a median dark stripe and one 

 fainter each side. Legs pale yellowish ; femur I white below, with long white hair, 

 dark brown in front and behind with a pale stripe above ; no fringes under tibia I, 

 no dark lines above, femur III mostly dark brown in front ; femur IV dark at tip, 

 also patella IV. A row of bristles over first eye-row. A large flattened spine on 

 inner side near tip of tibia I. Femur III not humped at tip ; patella III somewhat 

 swollen toward tip, with a black spot in front below, and above a large long spur ; 

 no dark streak above ; tibia III constricted at base. Male palpus with snow-white 

 hair on outside of tarsus. What I take to be the female has a white-haired clypeus, 

 three black stripes on the venter, and the femora not distinctly pale on base ; other- 

 wise much like the female of F. coecatiim Htz. Length, $ 4 mm., 9 5 ni™. 



Male and female from Punta Gorda, Fla. , and a male from Palm 

 Beach, Fla. 



Pellenes californicum, new species. 



Eye-region black, rest of thorax pale reddish-brown, clothed with white hair ; 

 a median black spot behind, not reaching forward. Abdomen black above, a basal 

 white band, a large transverse spot in front of middle and a large longitudinal spot 

 just behind this, white. Venter pale, with three black stripes, sternum pale. Legs 

 pale yellow ; femur I, black above and on outer side, with a fringe of black scales 

 on outer side near tip ; patella and tibia I not fringed below, but with black hairs 

 above on outer side ; rest of leg pale yellow, with white hairs. Mandibles and cly-
