26 SECOND YARKAND MISSION. 



The female is rather smaller, but resembles the male in general colours and form ; the 

 spiracular plates are of a deep red-brown colour and the genital aperture is small, of a trans- 

 verse-oval shape margined with red-brown, and on each side of it is a longitudinal row of 

 several short transverse red-brown lines, the rows converging forwards. 



Hab. Murree, June llth to July 14th, 1873. 



23. CHIRACANTHIUM APPROXIMATUM, sp. n., PL II, Fig. 18, ? . 



Adult females : length a little over 4 lines. 



In colours, form, and general structure, this spider is exceedingly like ChiracantUum 

 adjacens, Cambr. The falces, however, project rather more forward, and the second or terminal 

 joints of the spinners of the superior pair are longer. The cephalothorax, legs, palpi, and 

 sternum are of a uniform straw-yellow colour; the falces, maxillae, and labium are dark 

 brown, the base of the maxillae yellowish ; and the abdomen is of a dull clay-colour, obscurely 

 marked with whitish cretaceous-looking spots. The spiracular plates being of the same 

 colour as the rest of the abdomen, furnish also a good specific character, those of C. adja- 

 cens being dark reddish-brown ; the form and size of the genital aperture are also quite 

 different, being very small, of a transverse, somewhat, oblong form, edged narrowly with red- 

 dish-brown, and divided across the middle by a broadish pale septum. 



Sab .Murree to Sind Valley, July 14th to August 5th, 1873. 



Genus AGR&ECA, Sund. 



24. AGROECA DEBILIS, sp. n., PL II, Fig. 19, ? . 



Adult female : length nearly 2 J lines. 



This spider scarcely differs in form and structure from Agroeca brunnea, Bl. 



The cephaloihorax is yellow, thinly clothed with brownish hairs. The normal converging 

 indentations are dusky, and the junction of the caput with the thoracic segments is marked 

 by a short, fine, longitudinal, red-brown line. 



The eyes are of moderate size, and placed in two tranverse, curved rows, the convexity of 

 both being directed backwards, but the hinder row is the longest and the most strongly 

 curved of the two ; they differ but little in size, and are all seated on black spots ; those of 

 the hind-central pair are rather further from each other than each is from the hind-lateral on 

 its side, the latter interval being nearly about equal to an eye's diameter ; the eyes of the 

 fore-central pair are contiguous to each other, and each is separated from the hind-central 

 eye opposite to it, by an eye's diameter, and from the fore-lateral on its side by a distinct, but 

 very small, space. The height of the clypeus, in the middle, is equal to the diameter of 

 one of the fore-central eyes. 



The legs are tolerably long and strong, of an immaculate yellow colour, and are furnished 

 with hairs and spines ; the spines on those of the first and second pairs are long, strong, and 

 consist of two (parallel) rows beneath the metatarsal and tibial joints ; each tarsus ends with 

 two rather weak and apparently non- denticulate claws, bereath which is a small, blunt, 

 yellow-brown, corneous-looking projection, furnished with several bristly hairs turned 

 upwards in opposition to the tarsal claws. The relative length of the legs appears to be 

 4, 1, 2, 3.
