Male. — The body is marked with the usual broad dorsal dark band 

 over carapace and abdomen, this band limited on each side by a pale 

 stripe clothed mostly with white hairs. The lateral edges of the 

 dorsal band more deeply colored, blackish, while each lateral pale 

 stripe is limited above by a denser, wavy, silvery line. Sternum yel- 

 low, with a darker stripe on each side, and several, more or less ob- 

 scure, dark and radiating lines, or with a continuous black mid- 

 ventral stripe and one toward each lateral border. Legs yellow, not 

 banded. Dark dorsal area of abdomen clothed with chiefly black 

 hairs, but embracing anteriorly a paler sagittate mark and five or 

 six pairs of spots formed by white hair. Sides of abdomen also 

 black just below pale stripe, the color becoming less dense ventrad. 

 Venter darkened in spots and streaks, but with a clear longitudinal 

 line on each side from epigastric furrow to spinnerets. 



First row of eyes longer than the second. Anterior median eyes 

 obviously larger than the laterals, their diameter being between one- 

 fourth and one-fifth greater; less than their radius apart, nearer to 

 the laterals. Eyes of second row large ; much less than their diameter 

 apart. Area formed by first and second eyes broader than height of 

 clypeus. 



This species in general much resembling the European D. f^mhri- 

 atus., but readily distinguishable from that species and the Japanese 

 fiTribriatoides in the differing structure of the male palpus. The 

 dorsal tibial apophysis presents a tooth, or spine, on the ectal side of 

 its base as in fimbriatus; but this is much larger, and the principal 

 branch differs in being distally acute instead of truncate or some- 

 what expanded. The inferior tibial apophysis is short and stout, bent 

 forward distally. A dense patch of spiniform setae at distal end of 

 tibia on ectal side, a corresponding, though less pronounced, patch of 

 similar but smaller setae at distal end of patella. See further, Plate 

 6, figure 41.
