PARAPHIDIPPUS, gen. nov. 
Type P. laniipes, sp. n., ¢. Mexico. 
This genus, which, if not absolutely distinct, is at any rate convenient for separating 
into groups the great number of species allied to Phidippus, may be distinguished from 
the latter by the fact that the eyes of the posterior row are not or scarcely wider than 
those of the anterior row, and the small eyes are a little further away from the lateral 
anteriors. The abdominal pattern, too, is characteristic, being without the triangular 
central pale spot, and the mandibles in the male are usually more highly developed, 
though otherwise there is no structural difference between the two. . 
Males. 
(Mandibles very stout, enlarged, with the lower tooth, or in P. chrysis 
the upper one, much elongated. Legs i. fringed with hair beneath, 
and to a lesser extent legs i1.) 
i, Lower tooth of mandibles always the largest. 
a. Fang of mandible less robust, less sinuous, and not or scarcely 
constricted in the middle, either quite simple or with a single 
prominence in the centre of the inner margin. Legs i. longer 
and more slender; tibia i. at least one-third longer than the 
patella and with the protarsus much less densely clothed with 
fringing black hairs. Palpal spine slender and almost straight. 
a'. Fang of mandible with a single prominence at the middle of the 
inner margin. Legs i. clothed beneath with a dense fringe of
