ARANEIDEA. 91 



From the localities recorded, this spider, though perhaps less numerous, appears to be 

 distributed nearly equally with the two foregoing species, and all three are probably found 

 together. The present species is very nearly allied to L. injucunda, Cambr., found in Egypt, 

 but quite distinct. 



113. LYCOSA CREDULA, sp. n. 



Adult female : length nearly 2f lines. 



This spider is very nearly allied to Lycosa nigriceps, Tlior., which it resembles closely in 

 form and general appearance, but may be distinguished by the absence of any constriction of 

 the median, longitudinal yellow band on the cephalothorax, and by the normal longitudinal 

 marking on the fore half of the abdomen being sharp-pointed instead of truncated at the 

 posterior extremity. 



The cephalothorax is of a bright yellow colour, somewhat obscured by a greyish 

 pubescence, which probably soon becomes more or less denuded ; the sides are narrowly edged 

 with black, a very little way above which edging is a narrow, dark, yellow-brown, sub- 

 marginal stripe, with a broad lateral band of the same colour along the upper part of each 

 side, leaving a median, longitudinal yellow band of equal width throughout, and scarcely 

 wider than the lateral bands of the same hue. The ocular area is black. 



The eyes are in the usual position ; the front row is distinctly shorter than the middle 

 one, and its two central eyes are placed on a small prominence ; these two are larger than the 

 laterals of the same row, and the interval between them is greater than that between each 

 and the lateral on its side ; the eyes of the middle row are much the largest, and form a line 

 shorter than those of the third row, though this latter is not so long, proportionately, as in 

 some other groups of Lycosa. The four eyes of the middle and hinder rows form a square 

 whose posterior side is longer than the rest. The height of the clypeus is more than double 

 the diameter of one of the fore central eyes. 



The legs are moderately long, and rather slender ; they are of a yellow colour, indistinctly 

 marked and annulated on the femora with yellowish-brown, and are clothed with hairs, spines, 

 and grey pubescence. Their relative length is 4, 1, 2, 3. 



The palpi are yellow, marked with brown. 



The f aloes are rather long, slender, straight, and directed backwards; their colour is 

 yellow, slightly marked longitudinally with brown. 



The maxillce and labiwm are yellowish, tinged with brown. 



The sternum is oval, rounded before, and pointed behind ; its colour is black-brown, 

 irregularly margined with yellow, and a median longitudinal stripe of the same colour extends 

 from the fore extremity rather more than half-way to the hinder one. 



The abdomen is dark-brown above, spotted minutely and striated with yellow ; a tapering 

 dentated yellowish median band runs throughout the upper side to the spinners ; the fore part 

 of this band contains the normal marking, distinctly defined by a dark-brown line, and sharp- 

 pointed at its hinder extremity ; in the hinder half of the dentated band may be indistinctly 

 traced the usual series of angular bars or chevrons, each of which is charged with two small 

 brown spots in a transverse line. The sides of the abdomen are irregularly striated with dark- 

 brown on a yellow ground, and the under side is paler, with still fewer brown markings. 



The genital aperture is not large, but is, as usual, of characteristic form.
