 mm. long, 7'6 mm. broad. 



Cephalothorax. — Obovate, yellow, moderatelj^ hairj', and furnished 

 with a few bristles. Pars cephnJica moderately high, ascending, ai'clied, 

 slightly depressed at rear of ocular area, and slightly compressed laterally, 

 segmental groove distinct; ocular area broader than long, raised, arclied, 

 black, furnished in front with a few short black bristles ; clypens hyaline, 

 sloping forward, moderately deep, very gently undulated. Pars tJioracira

 slightly procurved ; rnargiiiAil hand pale, undulated, reflexed, fringed 

 witli rather long fine hairs. l<Jyes. — Distributed over two rows of four 

 each, the front one being procurved and the rear pi'ocurved in front and 

 recurved behind ; front latera.l eyes largest of the group, two-aiid-a-lialf 

 times their individual diameter apart, elliptical, poised obliquely, and 

 mounted upon black rings ; front medians round, and separated from 

 each other by a space equal to about one-half their own individual 

 diameter ; reai- laterals smaller than their anterior lateral neighbours, 

 elliptical, poised obliquely, ringed with black ; posterior intermediate 

 eyes minute, round, widely sepai'ated, each just touching the outer ring 

 of its lateral neighbour ; both rows close togetlier (PI. xxii., fig. 79). 

 Leys. — Short, sturdy, concoloi'ous with cephalothorax, hairy, but display-

 hairs and long coarse bristles, but displaying naked areas ; inner ridge of 

 the furrow of each falx aimed with six strong teeth, aiid the outer with 

 ten smaller ones; between these two rows there is an intermediate sei'ies
