The reason which induces Baron Chaudoir to consider 
tlie Jajmnese insect as a local form of the widely-spread 
C. hyhrida is api^arently the existence of a numerous 
series of connecting varieties, found throughout the 
Northern Hemisphere of the old world along temperate 
latitudes between Japan and Western Europe. Otlier- 
Avise, the well-marked and constant differences offered by 
C. Japanensis would probably have led him to consider 
it a distinct species, and as such I prefer to treat it. It is 
ahvays smaller than C. hyhrida (5 to 5^ lines), and of an 
olive-green colour, with silky cupreous reflections, and 
Avitli the sides of the breast, and a broad ring round the 
femora and tibite, brilliant coppery. The thorax has 
similar straight sides, but it is more distinctly narrowed 
behind. The elytra in the ? have each, near the suture, 
and at a short distance from the base, a rounded dusky 
depression, which I do not see in C. hyhrida, or any of 
its varieties that I have examined. The white belts and 
spots of the elytra are, in all Mr. Lewis's specimens, as 
described by Baron Chandoir, viz., the humeral lunule 
is separated into two distant sjiots, the submedian fascia is 
oblique and rather narrow, without dentiform projections 
or thickened portions, and the apical lunule is very slender 
in tlie middle. 
Very abundant in the sandy beds of rivers at Osaka 
and Kobe. 
C. Leicisii, n. sp. 
Valde elongata, fusco-nigra leviter cuprascens, infra et 
pedibus cyaneis, pectoris lateribus aureo-cupreis, cinereo- 
villosis; elytris subtilissime granulatis, lunulis liumerali 
ct apicali, fasciaque mediana transversali flexuosa, albis ; 
labro brevissimo, medio hand producto, albo. 
Long. 7 — 7^ lin. $ ?. 
The form of the Avhite marks of the elytra in this species 
is exactly as in the tjq^ical form of C. hyhrida ; the shape 
of the head is also very similar, the eyes being only mode- 
rately ])rominent and the forehead very little depressed. 
But there the similarity ceases. The labrum in C. Lewisii 
is, in both sexes, remarkably short and broad, with nearly 
straight anterior edge (subdcnticulate in 9), and much 
rounded angles. Tlie elytra are greatly elongated, with
