This species is closely allied to the European C. Roeselii ; 
the sculpture of the female is very similar in the two species. 
C. japonicus is considerably larger, broader, and more 
convex ; the upper surface is less green in colour than in 
Rceselii. The large and well defined dark mark on the 
breast, and the dark sutures of the under surface, are also 
good points of distinction. In the female the dilatation of 
the epipleuras of the elytra near the base is very remark- 
able, and much greater than in Roeselii. Abundant* 
throughout Nipon and Kushiu.

This species is not at all closely allied to any described 
species I am acquaiiited Avith ; it belongs to Aube's sec- 
tion b, having the sides and epipleurse of the elytra yellow, 
without any intersecting dark colour. The antennae are 
yellow, with the four or five apical joints pitchy, except at 
their extremities. Palpi yellow, Avith the apical joint a 
little darkened. Head of a dark olivaceous colour, A\dth 
the labrum, and a broad triangular mark above it, yellow ; 
the orbit of the eyes is also yelloAv, narrowly so behind, 
but at the front part, Avhere it is connected with the other 
yellow mark, broadly so ; it appears to be quite smooth 
and shining, but, when examined with a strong magni- 
fying poAver, is found to be very finely coriaceous, and to 
have other larger, fine points sparingly scattered over it. 
The thorax is broadly margined Avith yelloAv ; it has the 
usual punctures at the sides and fi-ont, and is sculptured 
in a similar manner to the head, but the fine scattered 
points are even smaller and less numerous. The scutellum 
is yelloAvish in the middle. The elytra are of a dark 
oliA^aceous coloui*, Avith a bright yeUoAv margin ; this stripe 
is a little dilated at the extreme base ; it is narroAved in its 
posterior third, and a little before the extremity are a fcAV 
* I am greatly indebted to Mr. Lewis for enriching this paper with 
information as to the localities, and rarity or abundance of the species 
mentioned in it.
