tubercle in the centre. Wings absent. Legs slender, the 

 hind legs less than twice the length of the body. Coxa, of 

 fore legs only, with a spine ; those of the hind legs carinated 

 on the outer side. Femora of the fore and middle legs un- 

 armed, except a pair of distal spines ; those of the hind legs 

 slender, smooth, without any oblique ridges on the outer side, 

 channelled beneath, armed with a row of six small spines on 

 the inner inferior keel, and numerous very small and blunt 

 ones on the outer ; the distal spines quite blunt. Tibice of the 

 fore and middle legs with two rows of four spines in each 

 and a terminal pair : those of the hind legs are not expanded, 

 the spines on them irregular, 11 to 13 in a row, some of them 

 very small, tbe last pair very large ; two pairs of terminal 

 spines, the upper of which are the smaller. Tarsi without 

 pads, four-jointed : the relative length of the joints is 1, 4, 

 2, 3 — the third considerably shorter than the second in the 

 fore and hind legs, but nearly equal to it in the middle

Female differs from the male in the following cha- 

 racters : — 



Head has the epicranium smooth ; in the maxillary palpi 

 the third and fourth joints are about equal, and the last joints 

 of both the maxillary and labial palpi are rounded at the 

 end. 



Thorax : The lateral margins of the metanotum are 

 slightly thickened.

 stout, and but slightly curved.
