Hi.Ai'Yi.rs. 



This name is proposed for a sub-generic division of Eleodcs, in which the basal joints 

 (usually three) of the anterior tarsi of the male are clothed with a dense silken pubes- 

 cence, obliterating- entirely the median groove, evident in the remaining joints and in the 

 entire tarsus of the female.
