b. Legs i. and ii. in both sexes with fringes of hair on the sides 
or beneath. . . ... ; . os... . . « PARaPHIDIPPUS, gen. Nov. 
2. Posterior row of eyes distinctly wider than the anterior. 
a. Carapace uniformly rounded on the sides. Abdomen with a 
central dorsal triangular pale spot. . . . . . « . Purprepus, C. L. Koch. 
b. Carapace dilate laterally, in front of the small a eyes. Abdomen 
without the characteristic central pale spot . . . . . . Parnaznus, Peckh. 
CHELIFEROIDES, gen. nov. 
Type C. segmentatus, sp. n. Guatemala. 
Leg i. very incrassate, the tibia being almost as broad as long and, with the protarsus, forming a distinct 
chela, functional probably both in copulation and in the pursuit of prey. Cephalic quadrangle not longer 
than wide, but broader behind ; the small eyes placed midway, or, if anything, slightly nearer the anterior 
laterals. Tibia and protarsus iv. without spines. Body flat, as in Rudra, and the maxille, as in this 
latter genus, rounded at the apex. 
This spider very much resembles Chirothecia, Tacz., but differs in the length of 
the cephalic area (see Peckham’s identification of that genus, which he regards as a 
“ Homalattid ”). 
1. Cheliferoides segmentatus, sp.n. (Tab. XXII. figg. 12, 12 a-f, ¢ .) 
Type, d, in coll. Godman & Salvin. Total length 4 millim. 
For colour and structure, see Plate. 
Hab. Guatemata (Sarg). 
It is very difficult to place this species in its proper systematic position. If, as 
Peckham considers, Chirothecia is a ‘“ Homalattid” and Audra a “ Marptusid,” 
C. segmentatus falls between the two, and removes any distinction which might 
have been supposed to exist between the groups. For the present it is placed in the 
Phidippee. One would suspect by its general appearance that this spider mimics 
one of the Pseudoscorpions. 
RUDRA. 
Rudra, Peckham, Proc. Nat. Hist. Soc. Wisc. 1885, p. 76 (Dec.). 
Type R. geniculata, Peckham. Guatemala. 
Tibia and protarsus iv. without spines; femur i. with, at most, one spine at the apex in front. The spines 
beneath the protarsi of the first pair of legs long, the basal ones three-fourths as long as the segment. 
Coxe i. at least two-thirds of a diameter apart at their base. Sternum twice as long as broad, oval- 
elongate, not much dilate behind, but with an abrupt contraction in the middle, forming a conical point. 
The cephalic area has a pencil of three or four stiff bristles on each side, below the small eyes. 
The males of the two known species belonging to this genus have not yet been found, 
but the females may be distinguished as follows :—
