niger, capite cupreo-iiitido, thorace elytrisqne opacis, pal- 
pis, anteunarum articulis 3 basalibiis, pedibusque rufo- 
tcstaceis ; thorace brevitcr ovato, grosse crebre puuctato ;

flava. 
Long. 6 lin. $ . 
Nagasaki; two examples. 
Nearest allied to C. guttatus (Escli., Philippines) and 
punctatus (Chaud., Australia). Elongate and slender ; 
antennie long, Avith middle joints dilated. Terminal joints 
of the palpi Avidening a little from base to apex, and 
squarely truncated. Head shining coppery, Avith green 
reflections, rather closely and coarsely punctured, but less 
densely on the crown. Thorax ovate, all angles obtuse 
and rounded, surfiice very densely covered wdtli large 
punctures tending to become confluent ; basal foveas deep 
and narrow ; the colour is dull bronzed black, nearly opake, 
but with a greenish tinge on the sides. The elytra are 
nearly twice the Avidth of the thorax, and nearly three 
times the length, clothed Avith A'cry short and dark pubes- 
cence; deeply striated Avith A'ery coua'cx and closely punc- 
tnred interstices. Before the apex is a transverse ycUoAV 
S]iot lying on the 4th — 8th interstices, broadest on the 6th. 
The legs are pale reddish, Avith a faint dusky spot under 
the femora at the apex ; the autenna3 have the 3rd — 7tli

C. subhamatus, Chaudoir, Bull. Mosc. 1856, iii. p. 211. 
Widely distributed in Japan ; Yesso, Nagasaki. Taken 
by Mr. LcAvis also at Kiu-Kiang on the Yang-tsze, and 
by Mr. A. Adams on the coast of Manchiiria. 
I hesitated for a long time in referring this insect to 
the subhamatus of Chaudoir, on account of his giving the 
character " antennis articulo tertio villoso ;" Avhicli I take 
to mean that the dense pubescence begins Avith the third 
joint, Avhicli is decidedly not the case. As the species, 
hoAvever, agrees aaxII Avitli the long and excellent descrip- 
tion given by the author, I conclude to adopt his name. 
C. deliciolus, n. sp. 
Elongatus, gracilis; capite viridia^nco nitido, thorace
