ARANEIDEA. 65 



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 17th, 1874. 



79. DlJEA SUBARGENTATA, sp. n. 



Adult male : length rather under 2 lines. 



This spider is nearly allied to Z>ieea (Xysticus) Pavesii, Cambr., Journ. Linn. Soc., vol. 

 xi, p. 540, pi. 15, fig. 8, but it may be 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 denned, 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 

 occiput, with the point directed backwards. The height of the clypeus is just half that of 

 the facial space. 



The eyes are on round, whitish tubercles in the usual two-curved rows, which are very 

 nearly 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 

 on its side. The four central eyes form a rectangle whose posterior side is the longest and 

 anterior 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 

 genua, as well as the two extremities of the tibiae, and the fore extremity of the metatarsi, 

 being of a darker reddish yellow-brown,, giving them an annulated appearance. Those of the 

 third 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 brownish-yellow colour. The cubital and radial 

 joints are short, and are furnished with several longish, tapering, dark bristles ; the radial is 

 the 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, appai'ently 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, 

 sharpish pointed at its anterior extremity. The palpal organs are small and simple in form, 

 apparently encircled, or nearly so, with a very slender filiform spine. 



The falces are moderate in length and strength, sub-conical, and directed a little back- 

 wards. Their colour is like that of the cephalothorax. 



The maxilla and labium are of normal form, and of a light yellowish-brown colour.
