Beetle 21–29 mm long with a stocky, wide and highly convex body. Lower body, head and pronotum - black. Elytra, legs and antennae, palps and pygidium from light brown, red-brown to almost black-brown. Elytra elongated-oval, with 5 narrow rather strong or weak ribs, spaced in thick, fine dashed lines and wrinkles. Pygidium is large. The process of the pygidium is shorter and pointed at the end, in the female, for the most part, is absent. The larva is indistinguishable from the larva of the western and eastern May Khrushchev .

Caucasus, Middle and partly Southern Europe - France, southern Germany, Austria, Hungary, Romania, Northern Italy. Prefer places moderately moist with woody vegetation.

Beetles are found from late April to early June. At the same time, mating, nutrition and egg laying occur. Beetles eat leaves of fruit and deciduous forest species, as well as damage flowers. Females lay eggs in the soil to a depth of 15-25 cm, in heaps of 5-20 pieces. Prefer warmed soils with sparse soil cover. The eggs are oval, white. At first, the larvae feed on humus and small roots, in the future - large roots. Sensitive to soil moisture. During drought, they migrate to deeper layers of the soil; in spring and autumn, with increased moisture, they rise closer to the surface. Pupation of larvae of the last age occurs in June-July in an earthen cradle at a depth of 15–20 cm. The pupa is free, yellowish. Pupa stage 30–40 days. Three-year generation. Beetles and larvae hibernate in the soil.
