In the male sex the following cephalic limb armament is 

 found. Femora with four discoidal spines, ventro-external mar- 

 gin with four moderately elongate spines, all genicular lobes 

 with a very small conical spine, ventro-internal margin with 

 the formula Iililiiil. Cephalic tibiae with ventro-external 

 margin showing three minute and one large distal spine, the 

 first separated a greater distance from the others than they are 

 from each other; ventro-internal margin with six or seven spines, 

 the first two or three minute, the next large, the next half as 

 large, the last two very large and elongate, the last above the 

 ventral margin and adjacent to the side of the apical claw. 

 In the female this armament is similar except that the til)ial 

 spines are microscopically serrulate and proportionately heavier, 

 while the third spine from the end of the ventro-int(>rnal margin 

 is scarcely a third as long as the preceding spine. 



Compared with the male sex, females are seen to be decidedly 

 larger and heavier and apterous. The ocelli are exceedingly 

 minute, the pronotum with lateral margins v(M-y slightly more 

 heavily denticulate, the supra-anal plate similarly medio- 

 longitudinally carinate, linguliform, but slightly over twice as 

 long as proximal width, instead of being less than twice as long 

 as that dimension as found in the male.
