296 SPECIFIC ESCRIPTIONS OF 



central nearest to each, by an interval not differing 

 much from that between each other ; the hind-centrals 

 are distinctly oval, or rather somewhat semilunar in 

 form, smallest of the eight (except in one example, 

 when they were almost, if not quite, as large as the 

 fore-centrals), and at their hindermost point very near, 

 but not quite contiguous, to the hind-laterals. The 

 eyes of each lateral pair (of which the hinder is very 

 nearly equal in size to the fore one, are very near, but not 

 quite contiguous, to each other ; the interval between 

 them is narrower than that between the corresponding 

 eyes in almost any other yet described species. 



The hys are neither long nor very strong ; their 

 relative length is 4, 1, 2, 3, though between 2 and 3 

 there is in different examples the same variation 

 observed in other species ; sometimes they are equal, 

 and sometimes one, and then the other, very slightly 

 the longest: their colour is pale yellowish, and they 

 are furnished with hairs, bristles, and spines, but the 

 latter are not numerous, and appeared to be both 

 longer and slenderer than usual ; the genual joints of 

 the third pair have spines, from one to three on the 

 outer side, for the most part, three ; the superior tarsal 

 claws are pectinated (but not uniformly on all the 

 legs) beneath their hinder portion. 



The f dices are strong, and similar in colour to the 

 cephalothorax, but they do not appear to call for any 

 special remark. 



The maxilla have a few minute tuberculiform black 

 teeth at their base on the inner side, and, with the 

 labium (which has no hairs at its apex) and sternum, 

 are similar in colour to the legs. 



The abdomen is of an elongated, or cyliudrico -ovate
