upper part are a little suffused with brownish rusty-red, and its margins have a tolerably dis- 
tinct white border; the sides have a longitudinal brownish rusty-red band, which runs round 
the fore extremity, including the spinners, and joining in with the rusty-red colouring at 
the hinder extremity of the upper side. The under side is of a uniform pale dull yellow. 
Hab . — Route from Yarkand to Bursi, between May 28th and June 17tli, 1871. 
79. — Dma. subargentata, sp. n. 
Adult male : length rather under 2 lines. 
This spider is nearly allied to Dicect (Xysticus) Pavesii, Cambr., J ourn. Linn. Soc., vol. 
x b p. 510, pi. 15, fig. 8, but it may he distinguished without difficulty, if the descriptions of 
the markings on the abdomen, and the structure of the palpi in the two species are carefully 
compared. 
The cephalothorax is round behind, slightly constricted on the lateral margins at the 
caput, the fore extremity of which is broad and slightly roundly truncated. It is of a 
brownish-yellow colour, with a not very strongly defined, longitudinal, darker reddish yellow- 
brown band on each side of the upper part ; the caput is also rather suffused with lighter 
reddish yellow-brown, and there is a somewhat arrow-head-shaped yellow marking on the 
°cciput, with the point directed backwards. The height of the clypeus is just half that of 
tbe facial space. 
The eyes are on round, whitish tubercles in the usual two-curved rows, which are very 
dearly concentric, making the interval between the eyes of each lateral pair nearly equal to 
that between the fore and hind-central pairs. The interval between the eyes of the hind- 
central pair is distinctly greater than that between each and the hind-lateral eye on its side ; 
while that between the fore-centrals is less than that between each and the fore-lateral eye 
011 its side. The four central eyes form a rectangle whose posterior side is the longest and 
a nterior the shortest. The fore-laterals are but slightly the largest of the eight. 
The legs of the first and second pairs are long and moderately strong ; those of the 
second pair are, if anything, slightly the longer ; they are of a brownish yellow colour, the 
?enua, as well as the two extremities of the tibiee, and the fore extremity of the metatarsi, 
being of a darker reddish yellow-brown, giving them an annulated appearance. Those of the 
ibird and fourth pairs are much the shortest, the third pair being the shorter of the two ; 
these are of a plain pale yellowish hue ; and all the legs are furnished with hairs, slender 
bristles, and spines. 
The palpi are short, slender, and of a hrownisli-yellow colour. The cubital and radial 
joints are short, and are furnished with several longisli, tapering, dark bristles ; the radial is 
tbe shortest and has a not very long nor strong tapering apophysis at its extremity near the 
outer side, terminating with a sharp, somewhat corneous-looking point. There is also 
Another apophysis on the under side, apparently rather stronger, and obtusely pointed. The 
digital joint is as long as the radial and cubital joints together, and is of a narrow-oval form, 
s barpish pointed at its anterior extremity. The palpal organs are small and simple in form, 
a Pparently encircled, or nearly so, with a very slender filiform spine. 
The fa Ices are moderate in length and strength, sub-conical, and directed a little back- 
wards. Their colour is like that of the cephalothorax. 
The maxillce and labium are of normal form, and of a light yellowish-brown colour.
