 Chelicerae. Vertical, parallel, of moderate size; basal segment .30 mm. long, excavated along medial border so that a small oval opening exists between the two. Fang moderately robust, evenly curved. Fang groove distinct; promargin with two teeth as usual; retromargin with an obscurely fissidentate tooth, visible as such only from certain angles.

Maxillae. Parallel, probably without minute tubercle at outer distal corner; otherwise as in male.

Lip. Slightly longer than wide. Otherwise essentially as in male.

Sternum. Longer than wide in ratio of 4 : 3. Otherwise essentially as in male.

Legs. 4123. Tibial index of first leg 21, of fourth leg 15.

Spines. First leg: tibia only ventral 2-2-2; metatarsus only ventral 2-2; elsewhere 0, tibial and metatarsal spines robust, long. Second leg: tibia ventral 0-1r-0; metatarsus ventral 2-2; elsewhere 0. Third leg: none observed. Fourth leg: metatarsus prolateral and retrolateral 0-1; elsewhere 0. No palpal spines.

Abdomen. Broadly ovoid, longer than wide in ratio of 14 : 11, widest a little behind the middle; other features essentially as in male.

Epigynum. Of moderate size; epigynal plate wider than long; with a very shallow posterior marginal notch having a broad rim; two strongly chitinized depressions nearly twice the width of one of them apart (Fig. 367).

Carapace: generally reddish brown, somewhat lighter than in male; eyes on black spots; white lanceolate hairs scattered over surface except for triangular area overlapped by abdomen which is smooth and devoid of hair; with no definite stripes. Palps yellowish white. Chelicerae light reddish brown; lips and maxillae nearly the same with whitish tips. Sternum brown. Legs: first pair generally reddish brown with tarsi and middle of metatarsi yellowish white and numerous short white lanceolate hairs on dorsal surfaces especially of tibiae and patellae; second and third pairs yellowish white with distal two thirds of femora dark brown except dorsal surfaces and dark brown distal ends of patellae, tibiae, and metatarsi; fourth pair
