 femora beneath more or less ferruginous ; the anterior coxae armed 

 with stout ferruginous spines ; the anterior tarsi pale testaceous 

 and broadly dilated, the basal joint produced into an oblong process 

 that projects forwards over the following joints ; all the joints 

 covered with short white pubescence above, and with a thick long- 

 fringe of white pubescence behind, which is bright fulvous on its 

 hinder margin ; the first joint of the tarsus is narrowly margined 

 with fuscous anteriorly ; the posterior tarsi have bright fulvous 

 pubescence beneath, the first joint having a floccus of white at the
