262 SPECIFIC DESCRIPTIONS OF 



fore centrals from each other, and each of them from 

 the fore lateral on its side, are as nearly as possible 

 equal, though very slightly, if at all, less than that 

 which separates each of them from the hind central 

 on its side : the interval which separates the fore 

 laterals is double the length of the longest diameter 

 of one of them. 



The legs are short and very strong ; they are like 

 the cephalothorax in colour, but paler underneath the 

 femora; this joint in the third pair is proportionally 

 much stronger than in the other legs ; all are fur- 

 nished with hairs, bristles, and spines, a group of 

 erect bristles among the rest occupies the fore part of 

 the upper side of the metatarsi of the first and second 

 pairs ; strong spines of different lengths are thickly 

 placed beneath and on the lower part of the sides of 

 the tibise tarsi and metatarsi of the first and second 

 pairs. On the tarsi and metatarsi of the third and 

 fourth pairs similar spines are distributed more uni- 

 formly over the whole surface of the joints, and on 

 the genual joint of the 3rd pair there is one short 

 strong spine near its extremity on the outer side, 

 those on the tibiae both of the third and fourth pairs 

 being confined to a few on the outer side, and towards 

 the lower side only. Each tarsus terminates with 

 three claws, of which the two superior ones have 

 a single strong tooth towards the base on the lower 

 side. 



The palpi are rather long, strong, and similar in 

 colour to the legs. They are furnished with hairs, 

 bristles, and spines ; of the latter the radial and 

 digital joints have some short and strong ones, pretty 

 thickly grouped along both their outer and inner
