Small (cylindrical species, eovei-ed witli slioi-t, line appressed 

 pubescence. The antenme of male have the third joint elongate- 

 cylindrical, with a basal process as long as the joint itself, and 

 joints 4 to lU strongly tiabellate or with long fiat processes folding 

 like a fail; tarsi as long as the tibia3, with the first joint as long 

 as the two or three following. Two species have been taken in In-
