larger, but only embraces the base of the palpal organs. These 

 are somewhat pear-shaped, and terminate in a stalk bearing 

 one or two minute spine-like apophyses. 



The legs are of a clear yellow-brown colour. The order 

 of lengths is 4, i, 2, 3, but there is not much difference be- 

 tween I and 2. 



The cox^ do not fit into hollows in the sternum, but are 

 separated from that structure by a pale chitinous area which 

 extends between contiguous coxae, and also separates the 

 sternum from the maxillae, and those organs from the labium. 

 All the coxae bear a ridge below near the apex. 



The TROCHANTERS are all small. 



The FEMORA are strong, hairy, and somewhat acuminate ; 

 those of the first pair bear two strong spines on the inner 

 border near the apex. This is an important specific character. 



The PATELLA are short, and similar one to another. 



The TiBiJE are cylindrical. In the first and second legs 

 each bears below two parallel rows of four long spines. These 

 are very strong, and each lies in the direction of the long axis 

 of the leg. These are not present on the third and fourth legs. 



Similarly the metatarsi of the two posterior pairs are 

 unarmed, whilst those of the first two pairs bear beneath two 

 parallel rows of spines. These are similar to, but smaller 

 than those of the tibias, but each row contains only two 

 spines. 



The tarsi are rather short. In the case of the third pair 

 they are about half as long as the metatarsi, but in the others 

 they are even less than this. Near the apex of each there is 

 a deep constriction separating off a terminal subjoint. This is 

 small, is covered with hairs, many of which possess lateral 

 barbs, and terminates in two toothed claws. This description 

 of the legs is taken from female specimens. 



The ABDOMEN is of a greyish yellow-brown or clay colour, 

 and is covered with long hairs. It is provided above with a 

 dark brown, shining, horny scutum. This is of a somewhat
