Phytophagous Coleoptera of Japan. 167 



fulvous, the rest black. Thorax nearly twice as broad as 

 long; above transversely convex, impressed with large 

 shallow punctures. Elytra broader than the thorax, regu- 

 larly punctate-striate, interspaces smooth and shining, 

 impunctate. Thighs armed beneath with a minute tooth. 

 Easily distinguished from the preceding species by its 

 broader and more closely punctured thorax and by its 

 broader form.

It will be seen that the present species is very variable 

 in colour, it also varies greatly in the degree of punctation 

 of the thorax.
