Description.
Male. Size, 9.8 mm x 3.8 mm. Irregular rough dorsally, shining black-bronze with elytral foveae dull brassy, more shiny ventrally than above. Head with frons dull brassy green, slightly depressed, bronze between antennae, greener adjacent to eyes and near clypeus with greenish-bronze margin, slightly rounded on each side of median notch and greener than rest of frons, two irregular raised bronze callosites with minute punctures slightly above middle of frons, and dull transverse bronze area above antennal sockets, with cells larger than on frons, surface covered with white setae; antennae bronze with slight reddish cast on first five antennomeres; occiput with broad smooth grooved longitudinal carina with adjacent areas more heavily punctured than frons. Pronotum about 1.6 times wider than long, widest just behind middle; anterior margin slightly sinuate; posterior margin strongly sinuate; disc convex, uneven with longitudinal median depression on middle 3/5 of disc, depression margined by smooth raised, irregular, slightly-punctured lateral areas; another less distinct lateral raised area with larger punctures, nearer lateral margin than to longitudinal median depression. Elytra wider than pronotum, sides rounded basally then subparallel to widest at posterior 1/3, two indistinct, brassy foveae at 2/5 and 4/5 from base; four longitudinal costae present, first and strongest, runs parallel to elytral suture and from base to near apex, less distinct on posterior ¼ of its length; 2nd costa bisects anterior fovea, runs parallel to first costa, and merges with first costa at 1/6 distance from apex; 3rd costa is lateral to 2nd costa, less distinct, and much interrupted; 4th costa runs along lateral margin, is weak and wavy. Underside: long white prosternal setae; last abdominal ventrite semicircularly emarginate. Male genitalia as in
Fig. 19
; parameres sloping to middle and then narrowing toward base. Female. Size, 11.1 mm x 4.1 mm wide. Frons brassy-bronze with two bronze callosities; clypeus bronze, margin bronze-black. First and 3rd elytral costae merge about 1/6 distance from apex. 4th costa indistinct and interrupted; posterior abdominal tergite with shallow depression on either side of median carina (

Hosts.
At Okemos, Michigan 15 beetles were collected (
4-VI-72
and
5-VII-70
) on
Juglans cinerea
Linnaeus
, and
12 specimens
were reared from same host in
1974 and 1976
from pupal cells in the bark of a large dead butternut tree. These specimens key to
C. quadriimpressa
,
and have similar male genitalia, but their dorsal elytral sculpture is more rough and irregular, and the elytral foveae are less distinct. These beetles may represent a new species; however, additional studies are needed. Other specimens collected in Texas on
Celtis laevigata
Willd.
, near recently cut oaks key to
C. quadriimpressa
. These specimens are somewhat larger (10.0
–
13.0 mm long), have more setae on a mottled dull bronzy-green frons, less sculptured elytra and less distinct elytral foveae than beetles typically collected on oak. As is common for many species of the
C. femorata
species group, some variation exists in shape of male genitalia in this species. The specimen reared from black walnut in Idaho may represent an introduction, likely in nursery stock, but perhaps via imported firewood (
Westcott, 2005
).
Comments.
The male
holotype
(MNHN) of
C
.
quadriimpressa
Gory & Laporte
was compared with the
type
of C.
misella
LeConte (1859)
(MCZC), and are the same species. This common oak inhabiting species is usually smaller than, and the male frons is lighter green than, that of
C
.
femorata
Olivier.
