286 ARANEIDEA. 
lateral eyes almost to the posterior angles, broader in front, narrowing as it touches the margin; the 
clypeus, though fringed with white and ochre hairs,-is free from white scales ; avery broad band of white 
scales extends from behind the anterior lateral eyes, curving round over three-fourths of the carapace, 
convergent but not meeting at the centre. Central anterior eyes surrounded with ochre hairs. Three 
spots of white hairs occupy the central ocular area between the central and lateral posterior eyes. 
Abdomen black or deep red-brown, clothed with scattered silvery or golden scales, having a broad anterior 
pure white marginal band, followed by an oblique white spot and a semicircular spot, on each side; 
viewed from above, the two semicircular spots form the boundaries of a parenthesis; the dorsal area has 
a large triangular central white spot, with a pair of smaller ones halfway between it and the anterior 
margin ; ventral area entirely brown. Mandibles metallic green, clothed at their base above with pure 
white hairs, which become tawny at the sides. Femur of palpus entirely white above; patella margined 
with white scales; tibia and base of tarsus margined on the inner side with white scales, the tarsus 
otherwise black. Femur i. with a broad, white, oblique band at the base on the inner side ; inner and 
upper apex clothed with white scales; patella i. margined with white ; tibia i. almost entirely black ; 
protarsus and tarsus i. with white hairs at their base. Legs ii., iii., and iv. similar, but ii. with the 
femoral spot smaller and the protarsus whiter, and iii. and iv. with the basal half of the tibia white. 
Underside of legs and sternum brown ; tibia i. with dense black and some white hairs beneath. Palpus: 
bulb of the usual bilobate form; spine stout and bifid at its apex; tibial spur very strongly curved. 
Mandibles normal, with a pair of adjacent teeth on the upperside and a single rather larger tooth on 
the lower side opposite.

This species is apparently very closely allied to P. albulatus, but the apical spine of 
the palpus is aculeate (not bifid), according to our figure, taken from Peckham’s work. 
12. Phidippus bidentatus, sp.n. (lab. XXVII. figg. 11, 11 a-d, ¢.) 
Type, gd, in coll. Godman & Salvin. Total length 10 millim. 
(Carapace and abdomen accidentally devoid of hair and scales.) Legs red-brown, clothed with black hairs, 
especially beneath the femora and tibie of i. and ii. Mandibles bright metallic green, with blue 
reflections, having a single large upper tooth (the third is almost obsolete) and a single smaller lower 
tooth. Palpus: bulb bilobate, much enlarged posteriorly, the apical lobe enlarged, terminating in a very 
fine slightly sinuous spine ; tibial spur short, broad at the base and slightly curving downward. Cephalic 
quadrangle much wider behind ; central posterior eyes two-thirds of a diameter remote from the lateral 
posteriors. .
