THOMISIDiE. 
spinners,, and the under part, are of a pale, brownish-yellow colour; on the first there is a 
curved, black band extending to the anterior part of the sides, which are marked with oblique, 
imperfectly defined, black streaks, and on the posterior extremity spots of the same hue are 
disposed in longitudinal rows ; the under part is minutely spotted with brown, and a brown 
line on each side of the middle region extends to the spinners, the superior and inferior pairs 
of which have the second joint of a dark-brown hue; the colour of the sexual organs and 
branchial opercula is reddish-brown, and immediately below each of the latter there is an 
irregular, black spot. 
The Rev. O. P. Cambridge captured this handsome Thomisus in Dorsetshire, in the 
autumn of 1857.

Length of the female, l^ths of an inch; length of the cephalo-thorax, vth, breadth, T ‘th ; 
breadth of the abdomen, Jth; length of a leg of the second pair, 1th; length of a leg of the 
third pair, 5 3 5 ths. 
The falces are short, subconical, vertical, and are furnished with some erect bristles in 
front, towards the inner side; the maxillae are convex near the base; the lip is triangular; 
and the sternum is heart-shaped ; the legs are provided with hairs and strong spines ; the 
first and second pairs are longer and more robust than the third and fourth pairs, and are 
nearly equal in length, the second pair being rather the longer; and the fourth pair surpasses 
the third in longitudinal extent; the palpi are short, and are supplied with hairs and spines. 
These parts are of a pale, yellowish-brown colour, the lip being somewhat the darkest. Each 
tarsus is terminated by two curved, pectinated claws, and the palpi have a small, curved, 
pectinated claw at their extremity. The cephalo-thorax is compressed before, rounded on 
the sides, broadly truncated in front, and depressed in the posterior region ; its colour is 
yellowish-brown, the lateral margins being the palest, and an obscure, reddish-brown band is 
directed backwards from each lateral pair of eyes. The eyes are arranged in the form of a 
crescent on the anterior part of the cephalo-thorax ; the lateral eyes are seated on tubercles, 
and are larger than the rest, those of the anterior row being the largest of the eight. The 
abdomen is depressed, corrugated, much broader at the posterior than at the anterior 
extremity, the latter, which appears as if cut in a straight line across, projecting over the 
base of the cephalo-thorax ; short, strong hairs are sparingly distributed over its superior 
surface, and its colour is pale, yellowish-brown ; there are on the upper part five conspicuous, 
circular depressions; the three anterior ones form a triangle whose vertex is directed forwards, 
and the other two are situated parallel to its base; the sexual organs are of a red-brow T n hue; 
and the branchial opercula have a pale-yellow tint.
