the last reaching toward spinnerets. The cephalothorax is rather long, the 

 legs quite short, and patella iii simple. A female is similar, with white 

 clypeus; black abdomen, with a median white herring-bone stripe, and white 

 along sides. 

 Length 5 mm. 



One pair from Claremont (Baker). 



Epiblemum palpalis n. sp. 

 Plate XXXIX, Fig. 31. 



Cephalothorax iridescent golden or purplish, with some white scales, a 

 broad white band just behind the dorsal eyes, side margins narrowly white, 

 clypeus with a few white hairs; mandibles black, paler on tips; palpi wholly 

 pale yellowish, clothed with white hair; legs dark on femora, on patella and 

 tibia I beneath, and on patella, tibia, and metatarsus iv, rest of legs mostly 

 pale, a pale stripe above on femora i and 11 ; sternum dark. Abdomen 

 black, with black and some yellowish scales; three transverse white bands, 

 one basal, one before middle, and one toward tip, a narrow white band 

 encircles the spinnerets; these middle bands are straight across and not 

 oblique as in E. scenicum; venter dark, clothed with black and white hair. 

 Structure in general similar to that of E. scenicum, but the cephalothorax is 

 plainly longer than in that species. 



Length 5 mm. 



One female from Palo Alto (Baker). 



Metacyrba similis n. sp. 

 Plate XXXVIII, Fig. 9. 



In general this species is similar to M. tceniola, but the abdomen has two 

 unbroken white stripes, instead of two rows of dots; the venter is pale. The 

 cephalothorax is a trifle shorter and broader proportionately than in 

 M. tceniola; the male palpus has a shorter and broader palpal organ, the two 

 long tibial hooks very similar to M. tcsniola, but with the addition of a smaller 

 tubercle at their base; the bulb is broader,, especially at base, than in the other 

 species. 



Length 3 5.5 mm.
