Geodeyliagous Cohoptera of Japan, 291 
it is more rapidly narrowed towards the base ; the hind 
angles are moderately produced and acute, the Avhole base 
and anterior border coarsely punctured, the lateral plica 
separated from the lateral margin. The striae of the elytra 
are sharp, narrow, and punctulated, the interstices plane. 
The whole insect is glossy black, except the palpi, which 
are tawny-red ; but the antennae are sometimes rufescent. 
Although Motschulsky gives 7^ lines only as the size of 
his species, and says the tliorax is only a little narrowed 
behind, I think it is the same as the Japanese one, espe- 
cially as I have found specimens in a collection made in 
the North of China.
