This elegant little weevil is very like a Folydrusus, 

 but is distinguished by the scrobes being placed quite on 

 the front of the very short rostrum. 



Bukenji : one individual. 



Anosimus.

 A. pallidus, Roelofs, I. c. 



The species exhibits two distinct forms, which I believe 

 are the sexes, the male having the tibiae dilated and

 as a separate species. Neither can I treat the genus as 

 being provided with an ocular lobe on the prothorax. 



Nikko and Hitoyoshi, in May and June : apparently 

 very rare. 



Chlorophanus, Germar, Auct. 



Considerable difference of opinion has prevailed as to 

 whether the peculiar chin-piece found in some members 

 of this genus be a specific character or not. It is 

 certainly a sexual character peculiar to the male sex, aud 

 occurring only in certain species of the genns. The 

 females are characterised by the possession of an ex- 

 tremely long mucro at the extremity of the middle tibia ; 

 this sex is also provided with a peculiar structure, in the 

 form of a very hard chitinous body, probably an ovi- 

 positor or piercing instrument, which, being frequently 

 protruded, looks like an organ of the other sex ; it is, 

 however, bifid, whereas the oedeagus of the male is single
