ARANEIDEA. 19 



on the fore-half, may be traced in two longitudinal central lines converging backwards, as is 

 indicating the position of the normal, but here obsolete, dorsal marking ; the fore margin if 

 furnished beneath with a tuft of long, strong, upturned bristles ; the under side is of a uni- 

 form yellowish mouse-brown colour : the spinners of the inferior pair are yellow-brown, and 

 much the largest and strongest. 



The male resembles the female in all general characters, colours, and markings, and 

 differs but very little in size. The palpi are short but moderately strong. The radial joint 

 is a little shorter than the cubital, and has its fore extremity, near the outer side, produced 

 into a tolerably strong, rather long, tapering-pointed apophysis, the point spinous-looking, red- 

 brown, and slightly bent or curved ; this apophysis is about equal to the joint itself in 

 length. The digital joint is large, of an elongate-oval form, hairy, and rather longer than the 

 radial and cubital joints together ; the palpal organs are well developed, but simple, with a 

 tolerably strong, sharp pointed, slightly curved process of a brightish red-brown colour 

 situated on their inner side, and directed to their fore extremity.

The female only of this spider has been described. The following is a description of the 

 male. 



Adult male : length 2 lines. 



Cephalotliorax oval, broadest towards the hinder part, whence it narrows gradually 

 to the fore extremity ; its upper side is flattened-convex above, and a little highest at its 

 posterior extremity ; it is smooth, of a deep, rich brown colour, and thinly clothed with hairs. 



The eyes are in two very slightly curved rows, the curves directed backwards, and the 

 front row the shortest ; those of the hind-central pair are small, oval, but not placed 

 obliquely, near to each other, but separated by a distinct interval, less than that which divides 

 each from the hind-lateral on its side ; the fore-lateral eyes are the largest of the eight, and 

 the hind-centrals the smallest ; the fore-centrals are divided by an interval rather greater than 

 a diameter, and each is almost contiguous to the fore-lateral on its side ; the interval between 

 each hind-lateral eye and the hind-central next to it is nearly about the same as that which 

 divides the eyes of each lateral pair. The height of the clypeus is less than half that of 

 the facial space. 



The legs are moderate in length and strength, the femora strongly incrassated on their 

 upper sides ; they are furnished with hairs, bristles, and spines, the last chiefly on the tibiae 

 and metatarsi of the third and fourth pairs. Their colour is deep blackish-brown, that 

 of the metatarsi and tarsi being of a dull yellowish-brown hue. 



The palpi are moderately long and strong and of a brownish-yellow colour ; the radial is 

 rather less than the cubital joint in length, and has its fore extremity on the outer side pro- 

 longed into a strong, tapering, pointed, dark red-brown, straight, and rather prominent 

 apophysis, as long as, if not longer than, the joint itself ; the digital joint is large, oval, hairy, 

 and of a yellowish-brown colour ; its length exceeds that of the radial and digital joints
