 broad, feathered in the same way as the tip of the first 

 joint; on the underside the first and second joints have a 

 black point. Of the hind tarsi the first joint likewise is

 and have no tuft of black hairs, but they are a little in- 

 fuscated at the tips. Pulvilli and claws yellow , the latter 

 with a black tip.
