SeasonalityMost adults have been collected in May and June, with fewer in April and July. IdentificationThis species, in the subgenus Callisthenes, has completely reduced hind wings and quadrate metepisternum. Deep black, seldom with bluish lustre on sides. Prothorax rather flat, strongly narrowed basally, with backwards protruding, little rounded hind angles. Elytral sculpture with transverse lines at least as strong as the striae, together producing a system of more or less convex, slightly rounded tegulae which are arranged in more or less regular rows and becoming smaller, granulate towards the apex. Length 13 to 21.5 mm.
