AntennaeAntenna:

: antennal length reaches between basebase:
the part of any appendage or structure that is nearest the body
and end of elytraelytron:
the leathery forewing of beetles, serving as a covering for the hind wings, commonly meeting opposite elytron in a straight line down the middle of the dorsum in repose
, antennal flagellar segments elongateelongate:
much longer than wide
, scapescape:

smooth/punctate at apexapex:
end of any structure distad to the base
, antennal scapescape:
the first proximal segment of the antenna
≥ segment 3, rarely segment 3 > scapescape:
the first proximal segment of the antenna

: pronotumpronotum:
the upper and dorsal part of the prothorax
shape subquadratesubquadrate:
not quite a square

lateral armature absent. 
Prosternum: prosternal process dilated at apexapex:
end of any structure distad to the base
or not dilated at apexapex:
end of any structure distad to the base
, procoxal cavities open posteriorly, rarely closed posteriorly. 
ElytraElytron:
the leathery forewing of beetles, serving as a covering for the hind wings, commonly meeting opposite elytron in a straight line down the middle of the dorsum in repose
: elytral length reaching or close to end of abdomen, elytral apicesapex:
end of any structure distad to the base
rounded or truncatetruncate:
cut off squarely at the tip
, emarginateemarginate:
notched at the margin
or with tooth or spinespine:
a protuberance with an acute (sharp) distal end
, elytral color black or yellow, elytral color pattern present or absent. 
Legs: visible tarsomeres: 4, femora slender, protibial spurs: 2, tarsal claws simple.

Frons frons:
the upper anterior portion of the head capsule, usually a distinct sclerite between the epicranium and clypeus
comparatively broad, flat, without carinaecarina:
an elevated ridge or keel, not necessarily high or acute
, with longitudinal smooth line or groove in middle part of posterior half, and produced tubercletubercle:
a small knoblike or rounded protuberance
near antennal basebase:
the part of any appendage or structure that is nearest the body
. AntennaeAntenna:
in larval and adult insects, paired segmented appendages, borne one on each side of the head, functioning as sense organs and bearing a large number of sensilla
shorter than body, thicken slightly toward apexapex:
end of any structure distad to the base
[C. japonicus (Chevr.)], rarely longer than body, thin [C. gracilipes (Fald.), male], contiguouscontiguous:
so near together as to touch

the part of any appendage or structure that is nearest the body

truncate at apexapex:
end of any structure distad to the base
or with truncatetruncate:
cut off squarely at the tip
sharp outer angle; as an exception rarely rounded (C. motschulskyi); with dark brown and lightcolored adherent hairy coat forming characteristic pattern for each species, consisting of spots and transversetransverse:

Differential diagnosis

The spine-free antennaeantenna:
in larval and adult insects, paired segmented appendages, borne one on each side of the head, functioning as sense organs and bearing a large number of sensilla
, slender femora, and first metatarsomere shorter than remaining 3 combined will distinguish among most close relatives.
