distal ends of tarsi and metatarsi black. Palpi of the same color 

 as the posterior legs. 



Comparisons. —Easily distinguished from all others of the genus 

 by the great thickness of the first legs. This is a character, united 

 with that of the great lieight of Ihe cephalothorax in front, which 

 would seem to warrant the establishment of a new genus for it.

Eyes. — First row shorter than the second, lateral eyes slightly 

 larger and sightly lower. Second eyes almost their diameter apart, 

 slightly larger than third eyes. Third row slightly wider than 

 second, its eyes nearer second row than each other. Donsal eye 

 ai'ea not one-fifth the length of the cephalothorax. 



Form. — Cephalothorax comparatively slender, in front highest 

 and not quite one-half as wide as the greatest transverse diameter. 

 Sides of head steep. Length of chelicera about 1^ times the 

 height of head in front. Sternum a little longer than broad. 

 Legs rather stout, thickly covered with short liaii's. A prominence 

 on the supero-lateral angle of the chelicera. Superior spinnei'ets 

 about as long as the inferior. 



Dimensions. — Length of cephalothorax, 6.8 mm 



Length of abdomen, 9 mm. 



Length of first leg, 19 mm. 



Length of second leg, 17.2 mm. 



Length of third leg, 16 mm. 



Length of fourth leg, 23 mm. 



Color in Life. — Cephalothorax above pale chocolate-brown, two 

 broad, parallel black stripes on the dorsum, separated from each 

 other by about their own width, and extending from (and embrac- 

 ing) the second and third eyes to the posterior margin of the 

 thorax ; a narrow buff line between the second eyes ; a narrow 

 black submarginal and a black marginal line on the thorax; 

 region between the eyes blackish, and a narrow, short black 

 line on each side just ventral to the dorsal eyes. Sternum 

 black with pale hairs. Abdomen above with a broad dark-brown
