112. LTCOSA STELLATA, sp. n. 



Adult female : length from 4 to 5^ lines. 



The cephalothorax of this distinct spider is of a brown colour, and clothed with a 

 short sandy-grey pubescence ; there is a large, very distinct, star-shaped or radiate yellow- 

 ish marking at the occiput, divided longitudinally by a dusky red-brown line, strongish at 

 each end, and produced before into an obtuse, somewhat transverse, oblong marking a 

 little way behind the ocular area, notched at its fore-margin, and often marked with the bifid 

 continuation of the bisecting line on the stellate portion ; there is also a pale yellowish sub- 

 marginal, and generally broken, band on each side ; these markings, seen very distinctly on 

 immature examples, are more or less obscured by the pubescence in adult specimens. 



The eyes of the foremost row form a line distinctly shorter than the middle row, and 

 its central pair are distinctly larger than the laterals, and are divided by an interval larger 

 than that which separates each from the lateral eye on its side ; the height of the clypeus 

 very little, if at all, exceeds the diameter of one of the fore-central eyes. The ocular area 

 appears to be broader behind than it is long, and the eyes of the middle row are considerably 

 larger than those of the hinder one, forming a line nearly about equal to that formed by the 

 laterals of these rows. 



The legs are rather long, tolerably strong, of a yellowish hue, and pretty distinctly 

 annulated with dark brown ; they are furnished with hairs and spines, and the colour and 

 markings are liable (in adults) to be obscured more or less by a rather dense, short, sandy- 

 grey pubescence; their relative length is 4, 1, 2, 3. 



The palpi are similar in colour and armature to the legs. 



The f aloes are long, strong, straight, and perpendicular : they are of a reddish-yellow- 

 brown colour red-brown at the base and extremities in front, and furnished with numerous 

 long, prominent bristles. 



The maxill(B are yellow-brown, and the labium deep brown with a pale-yellowish apex. 



The sternum is deep brown, clothed with grey pubescence. 



The abdomen is of a blackish-brown colour on the upper side. The normal longi- 

 tudinal marking on the fore half is indicated by broken, surrounding, submarginal, reddish- 

 yellow markings, and its posterior extremity is truncated : following it is a series of opposed, 

 oblique, yellowish markings, these being the broken portions of the normal angular bars, which 

 are, however, sometimes perfect ; and each bar contains a black spot : outside these angular 

 bars is, on each side, a longitudinal row of yellowish spots. The sides are brownish-yellow, 

 spotted and marked with black-brown ; and the under side is also brownish-yellow, without 

 any markings. The genital aperture is of a characteristic form, and its colour is red-brown. 



The male resembles the female in colours and markings, but is rather smaller.
