maxillary palpus fairly long, the terminal joint about as long 

 as the preceding two together. Mentum transverse, emarginate 

 in front ; ligula divided into two strongly diverging slender 

 branches, with long fringes at the anteri(jr edge ; the labial 

 palpi with the basal joint very long and slender, the 2nd short, 

 the .'}rd long. Pnmotum more or less rectangular and parallel- 

 si<led, without lateral angulation, iinely margined at the sides 

 and base, generally with a median dorsal groove. Hcutellum 

 wanting or reduced to a very narrow vestige. Elytra narrow, 

 with dorsal stria:" and very narrow epipleura?. Prosternum not 

 much elevated behind the front coxa> and not pointed behind. 



The two sexes do not differ externally, the only exception 

 known to me being Fujidus caviceps, the male of which has 

 a very remarkal)le backward extension of the mentum. 



A small but imj)ortant distinctive feature of the genus is 

 the reduction of the scutellum, which is either absent or 

 represented only by a very narrow vestige. Various other 

 distinctive features render the genus quite unmistakal)le, viz., 

 the elongate shape, the strongly deveio})ed canthus com[)letely 

 dividing the eye and the very peculiarly formed club of the 

 very short and compact antenna. The three-terminal joints 

 have not the usual dull downy inner and outer faces, but are 

 hard and shining, with the sensory surface confined to the 

 hollowed terminal ])art alone of the very short joints.
