16 SECOND YARKAND MISSION. 
The maxillce are of moderate length and strength, curved over the labium ; impressed 
along the middle, and, with the labium, which is of an oblong-oval form, similar to the 
falces in colour. 
The sternum, is oval, pointed behind, and similar in colour to the cephalothorax. 
The abdomen is of an oblong-oval form, rounded behind and truncated before ; it is 
of a straw-yellow colour, thinly clothed with hairs, some of which are blackish-brown, an 
most numerous at, and below, the fore-extremity of the upper side ; on the fore-half of the 
upper side, four impressed spots form a quadrangular figure whose interior side is rather 
less than its posterior one, and whose longitudinal is greater than its transverse diameter. 
The spinners are tolerably strong, hut not very long ; those of the inferior pair are the longest 
and strongest. Such traces of it as were visible indicated that the genital aperture would be 
of small size.

13. — GnaPUOSA STOUCZK2E, sp. n., PI. II, Pig. 12, 3 . 
Adult male : length 4} to 4f lines. 
Cephalothorax oval, rather broad and truncated before, but only slightly constricted 
on the margins at the fore part of the caput ; the hinder slope is rather abrupt, and the 
profile line has a slight slope all the way to the eyes. The colour is a dull orange yellow ; the 
normal grooves and indentations (which are not very strongly marked) are of a more dusky 
hue, the thoracic indentation forming a red-brown line. The surface is clothed with sandy 
grey pubescence. 
lhe eyes are of tolerable size, and placed, as usual, in two transverse, slightly curved 
lows. Ihe convexity of the curve of the hinder row, which is the longest, is directed f° r 
wards, so that the interval between the eyes of each lateral pair is as great as that between 
the eyes of the fore and hind-central pairs. Those of the hind-central pair are narrow-oral, 
placed obliquely, and separated by a rather less interval than their longest diameter, an 
each is, as nearly as possible, the same distance from the lateral eye of the same row, on ib 
side, as the latter is from the fore-lateral eye opposite to it. Those of the fore-centra 
pair are placed on a slight prominence, and are the largest of the eight, 'they are separated 
from each other by an interval of rather less than an eye’s diameter, forming a line per- 
ceptibly longer than that formed by those of the hind-central pair. Each fore-lateral eye i s 
very near to the fore-central on its side, but not contiguous to it. The clypeus, in height, 
exceeds the diameter of one of the fore-central eyes, and is furnished with a few strong 
prominent black bristles. 
The legs are strong and moderately long, their relative length being 4, 1, 2, 3. The} 
are a little paler than the cephalothorax, and are clothed thinly with a greyish sandy-coloure 
pubescence, besides other hairs, bristles, and spines. Excepting a very few on the u PP e ^ 
sides of the femora of all the legs, the spines are confined to the tibiae and metatai si ° 
those of the thfrd and fourth pairs. The two terminal tarsal claws appear to vary in f _ ie 
number of their pectinations, which do not exceed three or four at the most, and which 111 
the third and fourth pairs seem to be fewer than in the first and second. Beneath these 
claws is a small elaw-tuft ; and the tarsi of the first and second pairs have a scopula under 
neath them.
