Found, not uncommonly, in many parts of the islands by 

 ]Mr. Lewis, in honour of whom I have named this very tine 

 and distinct species.

7'. car.'fitans, Trich. Illustr , p. 144. 



This -pecies, originally found by Ilerr. Nietner in Ceylon, was 

 met with by Mr. Lewis in various parts of Japan. It may be 

 distinguished from the other Japanese species bv the rufous colour 

 ;iii(l attenuated form of the elytra; but in some individuals the 

 colour of the elytra is much more obscure than in the specimens 

 taken by II. Nietner.
