SYNAMA.—COCCORCHESTES. 121 
The colours and pattern of the abdomen are similar to those of the male, though the dark patch on the upper- 
side suffuses itself more on the sides of the hinder part, thereby obliterating the posterior angular points. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
ERIPUS, Walckenaer. 
Eripus trifidus, sp. n. 
Adult female, length 22 lines ; height of the abdomen from the spinners to the summit of the central prominence 
a little over 3 lines. 
Cephalothorax broad, rounded behind, and strongly constricted on the sides forwards, narrow in front. The 
ocular region a little elevated, and sloping from behind that gradually up to the beginning of the posterior 
slope, which is short and roundish in profile. Its colour is a pale yellow, with a broadish central longi- 
tudinal dark brown band reaching to the ocular area and subdivided longitudinally by a yellow line, each 
of the subdivided parts being continued forwards in a narrow stripe from the eyes to the lower margin of the 
clypeus, which itself has a diffused brown marking in the middle. The sides of the caput and thorax are 
marked with a border of broken brown markings. . The surface of the cephalothorax is furnished with 
numerous pale erect coarse hairs, among which are some longer black obtuse bristles in the median line. 
The eyes are small, four form a central quadrangle, whose length is greater than its breadth, and each lateral 
pair is seated at the base of a pointed prominence near the hind-lateral eye on that side. The height of 
the clypeus appears to be about half that of the facial space. 
The legs are short, tolerably strong, 1,2, 4, 3; they are similar in colour to the cephalothorax, the femora of 
the two hinder pairs marked with blackish underneath, and all are profusely armed with bristles and 
strong spines, many of the latter having the appearance of being articulated to tubercular prominences of 
a spiny nature, especially on the tibizs, metatarsi, and femora of the first and second pairs. 
The falces are moderately long, not very strong, a little inclined backwards, yellow, with a longitudinal brown 
stripe in front of each falx. 
The palpi are similar to the legs in colour, short, and faintly annulated with brown. 
The maville are short, somewhat rounded at their extremities, and inclined towards the labium. 
The labiwm is short, rather less than half the length of the maxille, and rounded at the apex. The colour of 
these parts is yellow, clouded in part with blackish-brown. 
The sternum is heart-shaped and yellow. 
The abdomen is short, but greatly elevated, being gradually drawn out above into a tall, tapering, central 
eminence, with another short one at some little distance on each side of it and divergent from the central 
one. All three have a somewhat spine-like termination, tipped with two or three short bristles. The 
abdomen is of a yellowish-white colour, with a longitudinal central tapering yellow-brownish band, 
margined in part with blackish, and running from the middle of the fore extremity to the tip of the 
central eminence; another more diffused black or brownish band or marking on each side runs similarly 
to the top of each of the lateral eminences, and from the side of the base of each of these a blackish stripe 
runs perpendicularly downwards to near the spinners; the central eminence also has a yellow-brownish 
longitudinal stripe on each side, and one behind; near the middle of the upperside in a transverse line 
are two roundish conspicuous black spots, one on each side of the central stripe. The whole of the upper 
part and sides are furnished with long, strong, erect, rather obtuse, spine-like bristles. The genital aper- 
ture is small but of characteristic form, and the spinners are short and compact.

COCCORCHESTES, Thorell. - 
Coccorchestes scarabzeoides, sp. n. 
Adult male, length +; of an inch or § of a line ; adult female, length scarcely 1 line. 
Cephalothoraw nearly quadrate, slightly broader than long, of a uniform convexity above, with none of the 
ordinary grooves or indentations; hinder slope nearly vertical. Colour black; the surface shining,
