Additional material examined. AZERBAIJAN: NAXÇIVAN, Culfa, 26.v.1974, M. Volkovitsh lgt., 1♀ ( NMPC).

Redescription. Coloration ( Fig. 36 ). Head dark slate blue to black, mouthparts terra-cotta to chestnut brown, antennae sienna to sepia. Prothorax saffron yellow to orange, meso- and metasternum, ventral part of abdomen, scutellum and elytra dark slate blue. Legs sooty to black, femora with slight bluish tinge, knees more or less infuscate.

Male. Eyes only slightly protruding, slightly reniform, head across eyes moderately narrower than pronotum, head before eyes distinctly longer than length of eyes in dorsal view, head behind eyes straight, narrowed posteriorly. Antenna presumably not reaching elytral midlength (antennomeres 9-11 missing in the examined specimens). Surface of head finely punctate, covered by white, long, recumbent pubescence, semilustrous. Pronotum almost 1.25 times as long as wide, cordiform, its anterior margin straight, anterior corners rounded, lateral margins strongly sinuate, posterior corners rounded, posterior margin very shallowly emarginate in middle. Surface of pronotum finely and sparsely punctate, covered by sparse, white, long recumbent pubescence, lustrous. Pair of anterior pronotal depressions comparatively deep, preapical one shallow, hardly visible. Elytra parallel-sided, narrowing only in apical fourth, each elytron rounded apically. Elytral nervation absent. Surface of elytra imbricatepunctate, covered by long, white recumbent pubescence, matt; sutural pubescence denser than that on the rest of elytra. Last abdominal segment and male terminalia as in Figs. 9-14 ; projections of urite VIII concave and turned apically.

Female. Comparatively more robust than male, antenna reaching ca one third of elytral length, last antennomere constricted closely behind its midlength. Pronotum shorter, moderately longer than wide, anterior pronotal depressions only slightly developed. Last abdominal segment very similar to that of C. fucata ( Fig. 6 ).

Length J ♀: 6.6-9.0 mm.

Distribution. Azerbaijan: Naxçivan.
