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, and 

 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, but 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.

Genut GNAPHOSA, Latr. 



13. GNAPIIOSA STOLICZK^;, sp. n., PI. II, Fig. 12, t . 



Adult male : length 4J 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. 



The eyes are of tolerable size, and placed, as usual, in two transverse, slightly curved 

 rows. The convexity of the curve of the hinder row, which is the longest, is directed for- 

 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-oval, 

 placed obliquely, and separated by a rather less interval than their longest diameter, and 

 each is, as nearly as possible, the same distance from the lateral eye of the same row, on its 

 side, as the latter is from the fore-lateral eye opposite to it. Those of the fore-central 

 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 is 

 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, ], 2, 3. They 

 are a little paler than the cephalothorax, and are clothed thinly with a greyish sandy-coloured 

 pubescence, besides other hairs, bristles, and spines. Excepting a very few on the upper 

 sides of the femora of all the legs, the spines are confined to the tibise and metatarsi of 

 those of the third and fourth pairs. The two terminal tarsal claws appear to vary in the 

 number of their pectinations, which do not exceed three or four at the most, and which in 

 the third and fourth pairs seem to be fewer than in the first and second. Beneath these 

 claws is a small claw-tuft ; and the tarsi of the first and second pairs have a scopula under- 

 neath them.
