 com.ing darker near tips, usually banded twice on the apical half with black- 

 ish, in darkest specimens the hind pair frequently broadly black and the bands 

 confluent ; tibiae beset with stiff hairs but not with true spines except at tips, 

 in dark specimens the hind pair may sometimes be annulated with fuscous on 

 the basal half ; tarsi infuscated at tips, first and second segments subequal in 

 length; claws brownish translucent, deeply cleft or toothed at base, arolia
