 to ALE than to PLE in ratio of about 4 : 3. Height of clypeus equal to one sixth of the diameter of AME. Clypeus decorated only with a weak ventral fringe of light colored bristles, one long brownish bristle beneath outer border of each AME, a few inconspicuous loose white lanceolate hairs, and three brownish upturned bristles in lower angle between AME.

Chelicerae. Moderately porrect, divergent, and produced; basal segment .47 mm. long; a fairly robust hook on basal segment in front near distal end; with no basal boss. Fang of moderate size, rather robust in basal three fifths, then slenderer and evenly curved to tip. Fang groove distinct, considerably excavated; with two promarginal teeth, a small medial one and a robust one a short distance toward base of fang; retromargin with a small, somewhat fissidentate tooth nearly opposite the smaller of the two promarginal teeth, and a large process with ridges extending over much of the posterior surface of the basal segment a little closer to base of fang than to fissidentate tooth (a considerable degree of variation has been noted in both fissidentate tooth and the "hammer-headed" process among paratypes); these conditions shown in holotype (Fig. 368) and in a paratype (Fig. 369).

Maxillae. Parallel; longer than wide in middle in ratio of about 9 : 5; only moderately concave in middle of outer border; outer distal corner well rounded and without a tubercle or hook; scopula moderately developed along truncature.

Lip. Wider than long in ratio of 11 : 9; transversely grooved at base; well rounded distally. Sternal suture straight.

Sternum. Scutiform, quite convex; longer than wide in ratio of 13 : 10; widest between second coxae; anterior border slightly narrower than base of lip; anterior coxae wider apart than base of lip; posterior end a sharp point not extended between fourth coxae which are separated by one sixth of their width.

Legs. 1423. Tibial index of first leg 13, of fourth leg 12.

First coxae and femora moderately enlarged. All legs with a moderate supply of hair but without fringes or tufts.
