 to the base of the claws by a comb-like arrangement of 6 longer, 

 regular spines ; thei'e are one or two longer spines on the sides, distally, 

 and setose hairs on remainder of surface. Tarsus II with slightly larger 

 and more distinct scopular patches and a less numerous but more 

 regular row of spines down centre ; distal combs not so pronounced ; 

 2 or 3 more spines than on tarsus I, and slightly swollen distally. 



Tarsus III short, much stouter than metatarsus and swollen over 

 whole of lower surface, particularly in centre ; an entire and dense 

 scopula on under surface ; one or two spines on sides. Tarsus IV" 

 similar but not quite so swollen.

 and with a deep hollow on under outer side ; outer edge of hollow
