266 ARANEIDEA. 
11. Metaphidippus bispinosus, sp. n. (Tab. XXIV. figg. 1, 1a, 6, 6; 2, 
2a, 6b, 2.) 
Type 3, gynetype @, in coll. Godman & Salvin. Total length, ¢ 5, Q 6 millim. 
Coloration similar in both sexes, but not so well marked in the male. Carapace red-hrown, clothed with white 
hairs, with a band of white hairs extending from beneath the lateral eyes and reaching the middle of the 
lateral area, midway between the central stria and the posterior margin. Abdomen yellow, with an 
anterior-lateral white band, broken in front and dilate behind ; dorsally with a pair of elongate, slightly 
divergent, white bands, followed by an oval spot on each side, a sinuous spot dilate on the sides, and two 
/~-shaped white marks, the anterior the smaller, the branches of the posterior slightly dilate, just above 
the spinners (these white spots break a pair of black dorsal bands into four spots on each side); lateral 
area brown ; ventral area pale, with a broad central longitudinal brown band, having a pair of narrow 
pale dotted lines in the middle. 
Mandibles of the male variable in length, with a ridge on the inner upper margin, whence the inner side 
descends precipitately ; the basal segment short, with two small teeth on the upper and one much larger 
broad and conical tooth on the lower side (sometimes the mandible is elongated, and these teeth are then 
more or less remote from the apex). Fang either shorter or longer according to the development of the 
basal segment. Maxille dilate at their apex; outer apical angle slightly produced. Palpal bulb elongate, 
bilobate, with two broad black apical spines, the outer one the smaller of the two; tibial spur very short, 
directed sharply downward. Vulva consisting of a more or less circular area, with a transverse anterior 
cavity, its posterior margin deeply sinuate, having on each side a black slash, possibly indicating an orifice ; 
the posterior margin is so deeply but narrowly notched that the incision extends one-third through the 
vulval area.

12. Metaphidippus lanceolatus, sp.n. (Tab. XXIV. figg. 3, 3a-d, ¢.) 
Type, do, in coll. Godman & Salvin. Total length 5 millim. 
Dried example. Carapace red-brown, clothed on the cephalic area with white and olive-white scales, becoming 
golden towards the posterior margin; a broad band of transparent white (not opaque dead white) scales 
extends along the sides of the carapace from the lateral anterior eyes almost to the posterior margin, where 
it attenuates. 
Abdomen with a large oval dull olive-brown area, covered with dull golden-brown scales and hairs, extending 
from the anterior margin to the spinners, having, on each side, close to the lateral white bands, four 
darker brown spots, with a group of white scales in close proximity, the posterior groups blending with 
the lateral bands on each side; the eutire abdominal margin encircled with a broad band of white scales, 
followed at the sides and towards the lateral ventral area by yellowish-white hairs and scales; the central 
ventral area brown. Mandibles deep red-brown. Legs red-brown or yellow, annulated with groups of 
white scales. Femur i. entirely dark brown, the apices only of all the other segments of i., ii., iii., and iv. 
being brown, except the tarsi, which are entirely yellow. Palpi red-brown, clothed with dull white scales 
and hairs. Sternum pale red-brown. Coxe of legs yellow-brown, clothed with pale hairs. 
Cephalic quadrangle slightly wider behind; posterior central eyes a little nearer to the anterior laterals than 
the middle point between the laterals, anterior and posterior. Mandibles stout, elongate, divergent; the 
base compressed on the inner margin, bearing, about one-third from the insertion of the fang, two teeth, 
a larger anterior and a closely approximate posterior smaller tooth, with a much longer opposing tooth 
below ; fang long, slightly sinuous; with a convex prominence about the centre of the inner margin. 
The outer spine of the third pair of tibia i. much nearer the base of the segment; tibia ii. with two apical 
spines beneath, and two situated longitudinally beneath the segment about the middle. 
Palpal bulb comparatively narrow and elongate, with an apical lobe terminated by a short, broad, black 
lanceolate spine, which is concave in the middle; the base of the tarsus excavate on the outer side 
opposite the tibial spur, the inner side of the excavation being somewhat tuberculiform ; tibial spur short, 
black, sharp, and curving downward.
