To this u'lMius l)el()iig otif largest members of the family, yet none 

 of them excectl 7 mm. in length. The antenna^ are apparently 10- 

 jointed (the true sei-ond .ioint being very small and concealed) ; 

 second joint (really the third) of male much enlarged and bearing 

 near the base a cnrioiis slender articulated appendage furnished at 

 the tip with a Innisli of stiff, curved hairs. This extends forward 

 and is usually concealed in a deep cavity on the upper surface of 

 the joint. It is supposed to be used in clasping the antenuffi of the 

 female diiritig mating.
