DESCRIPTION OF A NEW ARANEIAD RAINBOW. 83 



the two comprising the second row are separated from their 

 anterior neighbours by a space equal to rather less than twice 

 their diameter, and from each other by about three diameters ; 

 the remaining two lateral eyes are located in the angles of the 

 cephalic segment at a distance from the tubercular eminence of 

 about 0"5 mm. 



Legs long, robust, armed with strong spines, yellow-brown with 

 dark annulations, clothed on the outer margins with hoary grey 

 hairs, on the inner margins with ferruginous grey ; coxse densely 

 clothed undei'neath with grey hairs. Relative lengths 1 = 2, 4, 3. 



Palpi long, similar in colour, armature, and clothing to legs. 



Falces long, robust, arched, glossy, sparingly clothed with black 

 hairs, apices divergent, yellow at base to about one-third their 

 length, where it terminates suddenly, and is thence dark brown 

 to tips ; the upper margin of the furrow of each falx is armed 

 with a row of four teeth, of which the two nearest the base are 

 the longest and strongest ; the lower margin is armed with two. 



Maxillce broad, arched, moderately long, divergent ; laterally 

 they are yellowish-brown, and clothed with rather long, hoary 

 greyish hairs ; inner surfaces glossy, pale flesh-coloured and naked, 

 but the edges are furnished with dense hoary scopulte. 



Lahiiun broader than long, arched, obtuse at apex, yellow-brown 

 from base to about one-half its length, thence pale flesh-coloured. 



Sternum shield-shaped, moderately arched, densely clothed with 

 short greyish hairs. 



Abdomen large, ovate, boldly projecting over base of cephalo- 

 thorax, grey, with dark brown markings, and a large brown patch 

 at the centre; sides grey; at the highest point of the anterior 

 extremity there is a recurved row of nine tubercles, the central 

 one of which is by far the largest and most prominent ; besides 

 these there are on each side of the superior surface of the abdomen 

 twelve tubercles, the first nine of which are distributed over three 

 slightly procurved I'ows of three each ; the fourth row on each 

 side consists of two each, and the twelvth tubercle is solitary; the 

 total number of tubercles is 33 ; the median portion of the superior 

 surface is, with the exception of two rather deep circular depres- 

 sions, smooth ; inferior surface yellow-brown with dark markings 

 and moderately clothed with hoary hairs laterally, and yellowish 

 pubescence in the median line. 



Epigyne, a small tri-lobed tubercular eminence, arched in front, 

 hollow within.
