171. Epeira foliata Hentz. — Male and female; Tepic. 



172. Epeira gibberosa Hentz. — A few specimens; El 

 Taste and San Jose del Cabo. 



173. Epeira zilloides, sp. nov. 



Plate XV, Fig. 2. 



Length S 7.5 mm., S 4 mm. Cephalothorax yellowish, blackish on pars 

 cephalica and extending back to dorsal groove; mandibles brown; sternum 

 brown, yellowish in middle; legs pale, al! the joints (except hind femora) 

 brownish, or with a brown ring at tip. Abdomen grayish, more yellow or 

 white at base and with a blackish spot each side, but the folium not continued, 

 a few dark spots and faint lines behind; venter with a broad dark region, con- 

 taining a pale spot behind the epigynum; S with the legs less distinctly 

 marked. P. M. E. less than their diameter apart, smaller than the A. M. E., 

 which are more than their diameter apart; mandibles rather prominent. Legs 

 short and stout; abdomen elliptical, broadly rounded in front and behind. 

 The epigynum shows a transverse elliptical brown area and two darker spots 

 in front. The palpus is rather complicated; the tibia broad, with very long- 

 bristles; the tarsus short. 



A few specimens from Tepic, Oct. Different from E. 

 gregalis Cambr. Looks like Zilla californica Bks., but in 

 that species the anterior femora are not darker at tips, there 

 is a band on middle of hind tibia, the folium on abdomen is 

 complete, and the ventral mark is narrower and without a 

 pale spot.

 ish, except a dark stripe from the epigynum to spinnerets-; abdomen sometimes 

 greenish. Cephalothorax about once and a half as long as broad, clothed with 

 pale hair; M. E. equal, forming a quadrangle nearly as long in front as high, and 

 a little narrower behind; P. M. E. separated by more than their diameter; A. M. 

 E. by twice their diameter; S. E. smaller than M. E. and considerably separated 

 from them, and slightly from each other. Legs quite thickly clothed with 

 white hairs and some scattered spines; sternum once and a half as long as 

 broad, pointed behind. Abdomen not quite three times as long as broad, 

 somewhat pointed in front, and continued behind in a cone, which is sharp 

 pointed at its tip. Male S mm. long, similar to female, except anterior femora
