Length 25-35 mm. Length 25-35 mm. C. maximoviczi, has the pronotum less transverse than the species of the C. sycophanta group, regularly rounded, less narrowed behind having sides not sinuate, almost parallel. Head and pronotum have dense punctures and fine transverse wrinkles. The elytra are elongated, with moderately convex and incised intervals. The punctures in the striae are just visible. The upper part is constantly dark having metallic, bronze, or rarely bluish, lustre.
It is quite common in southern Tibet (Linzhi and Changdu pref.), and in most of China, spreading southward up to Laos border (Lapouge, 1924). It is also found in Mongolia and in the Far East of Russia (Ussuri and Primorsky Krai), Sakhalin and Kurili Islands, Taiwan, Korea, and Japan.
From the north of Mongolia only one finding is known, that according to Obidov (2010: 63), should represent a new subspecies. Reading the original description this subspecies should be distinct from the typical populations because of the more rough sculpture of head and pronotum, the narrower prothorax, the color of the upper body without green or bluish luster, the elytral foveoles indistinct. These are very tenuous characters that also appear in isolated specimens of other populations and that do not justify the creation of a subspecies based on the specimen in question.

Notes: C. maximoviczi is diurnal, fully winged and a good climber on trees. It has been noted feeding mostly on caterpillars and sometime it is a conspicuous predator of the beech caterpillar, Quadricalcarifera punctatella (Kamata & Igarashi, 1997). In most countries where it lives, C. maximoviczi has one generation per year. Adult beetles begin active life starting from mid-May, They oviposite in early June and the full development takes about 30-45 days. The adult remains active until the middle of October, and overwinter in small cavities in soil.
The species has been named after Karl Ivanovich Maximovicz (1827 – 1891), a Russian botanist that collected and studied the flora of the Far East.
