inner edge of the chelicerae, (in most j'oung individuals the front row of four 

 are conspicuously larger than the other teeth above and behind — figs. 17-18 — 

 and no doubt are responsible for the "Actinoxia" rake described by Simon); 

 fang with a thin scollop-edged median extention within (figs. 16 and 18). 

 Abdomen oval or elliptical, dull tawny, marked with purplish-brown median 

 stripe and transverse bands, very dark, broad, and more-ror-less confluent, nearly 

 obscuring the ground-color, or pale and nearly obsolete (Plate XIII, figs. 9-10). 

 Spinnerets as shown in last mentioned figures. Sternum pale tawny, black- 

 setose; three pairs of shallow impressions, posterior pair large, irregularly elon- 

 gate, oval, ovate, or kidney-shaped (some variations shown in figs. 1-6, Plate 

 XIII), close together and converging cephalad, appearing paler than the sur- 

 rounding cuticle, because of the absence of fine black setae; anterior pair not 

 apparent in young individuals (fig. 6) and posterior pair smaller, farther from 

 each other and nearer the margin, the younger the individual. Labium a little 

 wider than long, more or less emarginate in front, generally unarmed (67%), 

 but frequently with one to three scattered spinules (33%) (Plate XIII, figs. 13-14). 

 Coxae of pedipalps with many spinules from base to apex of ventral surface, 

 more concentrated cephalo-mesad (Plate XIV, fig. 16; setae not shown) ; tarsi of 

 pedipalps densely scopulate below, well armed two subapical spines and two 

 others on each margin (71%) (Plate XIII, fig. 15P); next joint armed with 

 numerous spinose setae, but without well-defined arrangements. Legs tawny, 

 or with a decided oHvaceous cast; tarsi I and II with two sub-apical spines (86%) 

 metatarsi I and II with four apical spines and two near each margin (78%), 

 frequently, however, one of the apical and the inner of the sub-basal spines are 

 reduced to little more than spinous setae, scarceh' distinguishable from the 

 numerous variable setae omitted from the drawing (Plate XIV, fig. 15 I); 

 patella III with a triangular patch of spines, comprising a basal row of from four 

 to six, and four to eight scattered ones above, the number commonly not tmi- 

 form on the two sides of the same individual (Plate XIV, fig. 14), tibiae III 

 with a iew spines above and metatarsi III with marginal rows of spines above 

 and below; femora IV with an apical comb dorso-cephalad, metatarsi IV with 

 a row of spines on each side below and on the inner edge above, with at least 

 two apical spines above and two or more below, tarsi IV with armature very 

 indefinite, the spines varying from none to seven. Tarsal claws usually with 

 one or two larger basal teeth and an inner gradtiated row of from four to eight 

 smaller teeth, the largest nearest the apex (Plate XIV figs. 1 and 2); occasion- 

 ally the nvmiber is mtich redticed (Plate XIV, figs. 3 and 4). 



The percentages given above are deduced from tabulations 

 made from a careful comparison of forty-three individuals. 



Adult (J' (Plate XVI, fig. 2) — Length 13 mm.; cephalothorax 5 mm. long, 

 4 mm. wide; abdomen 6 mm. long, 3 mm. wide. Setae everywhere much more 

 robust and blacker than in female. Cephlx. rich tawny (the caput dappled with 

 olive-drab, excepting the glabrous longittidinal bands on either side of the 

 median row of setae), conspicuously bristly, especially the margins, posterior 

 margin scarcely emarginate; thoracic pit recurved, as in female; caput much 

 lower and relatively mtich smaller than in female, only half as wide as thorax, 

 sides nearly straight, arrangement of setae as in female; eyes and eye-tuber as 

 in female. Chelicerae much smaller and more slender than in female, darker 

 in color; rake of fewer teeth above. Abdomen with median band not in evi- 

 dence, but transverse bands nearly confluent, the pigment arranged in rings 

 all over the dorsum, but more confluent in the bands; spinnerets conspicuously 

 paler, light yellowish, more slender, the terminal joint relatively longer and 

 nearer size of medial joint. Sternum as in female, outline and impressions well 

 represented by fig. 3,' Plate XIII, but the most anterior pair of impressions less 

 apparent. Labium with setae only, no spinules; anterior edge not emarginate. 

 Pedipalps short, less than half as long as legs I (see photo) ; coxae P with spinules 

 from base to apex, but these less numerous, very slender, almost microscopic, 

 and more confined to the anterior half; tibiae nearly twice as long as the patellae, 

 -attenuated toward the apex; bulb nearly simple, the lower surface with a nearly
