176 ARANEIDEA. 
forming an indistinet pattern of a large yellow-brown oblong area in front, trifid at its hinder extremity, 
followed by three angular yellow-brown bars or chevrons ; the whole abdomen, however, has a minutely 
mottled or spotted yellow-brown and blackish appearance. Spinners of superior pair long and upturned; 
colour yellow-brown. Underside dull luteous, marked obscurely with blackish. 
Hab. Guatemata, Vera Paz (Sarg). 
ZOROCRATES, Simon. 
Zorocrates mistus, sp. n. 
Adult male, length 4 lines ; female, 44 lines. 
Cephalothorax yellow-brown, with a broad well-defined dark yellow-brown longitudinal band throughout on 
each side, and a tapering dark linear central stripe from the middle posterior eyes to past the thoracic 
junction, bisecting the central yellow-brown band—(in the male) a dark brown line also runs rather 
obliquely a little way backwards and outwards from each of the hind-central eyes. 
Eyes normal, The quadrangle of the four centrals is longer than broad, and rather narrowest in front. The 
interval between the hind-centrals is equal to a diameter, and is considerably less than that between each 
and the hind-lateral on its side. The fore-centrals are near together but not contiguous, and about double 
the distance from the fore-laterals. Height of the clypeus rather less than double the diameter of the 
fore-central eyes. 
Legs normal, 4, 1, 2, 3, yellow-brown, the femora of the male obscurely banded on the outer side with dusky 
brown, a thin scopula beneath the tarsi and metatarsi; a peculiar calamistrum on the outside at the 
posterior end of the metatarsi of the fourth pair of legs in the female. Terminal tarsal claws 2, strongly 
and closely denticulate. Spines beneath the tibiee of the first and second pairs of legs arranged in four 
pairs, beneath the metatarsi of the first pair of legs three pairs, and of the second two pairs. 
Palpi moderate in length, similar to the legs in colour, excepting the digital joint, which is dark yellow-brown. 
The radial and cubital joints are of equal length. The former has at its fore extremity on the outer side 
a strongish prominent apophysis tapering to its extremity, which is obtuse and bent in a kind of hook 
form, and has one or two small somewhat tooth-like prominences on its fore margin. Outside the radial 
joint, rather underneath, is a group of strong hairs, and the underside is furnished with others, some of a 
strong bristly nature, two strongish spines near the base, and another towards the fore extremity. 
Digital joint very large, oval, densely clothed with hairs, its fore part rather bent downwards. Palpal 
organs very prominent, not very complex, but composed of several strong corneous processes, of which the 
strongest is at their base and projects backwards. 
Falces rather long, moderately strong, straight. They are yellow-brown in colour, furnished with bristly hairs. 
Mawille rather long, strong, slightly rounded at their extremity on the outer, and obliquely truncated on the 
inner side, a little inclined to the labium, and constricted as well as impressed slightly in a shallow form 
across the middle. Colour dull pale yellowish. 
Labiwm longer than broad, hollow-truncate at the apex, which is pale yellowish, the rest dark brown. 
Sternum broad-oval, with a slightly prominent obtuse point at the posterior extremity, just in front of the base 
on the inner side of the cox of the fourth pair of legs. Colour pale yellowish. 
Abdomen yellow-brown, marked with dark brown, but the pattern was too much obscured, by its having 
become much shrunken, to be able to trace it. Spinners short, compact, with a narrow transverse 
mammillary organ or cribellum in front of the ordinary spinners. 
The female resembles the male in general appearance and colours; but the tibiw, tarsi, and metatarsi of the 
legs, especially of the first two pairs, are dark yellow-brown, and the sternum is darker and is marked 
with some dark oblique lines on the hinder part converging to the middle. The genital aperture is rather 
large, of a somewhat subtriangular and characteristic form.

This species may be easily distinguished from the type of the genus (Z. fuscus, 
Simon) by its much smaller size and different colour. From its possessing a
