Redescription. Coloration ( Figs. 33-34 ). Head iron grey, mouthparts sepia to rusty, antennae terra-cotta to sienna, antennomere 1 mostly somewhat darker. Prothorax iron grey, mostly with slight golden tinge, meso- and metathorax iron grey, ventral part of abdomen entirely iron grey in female, last abdominal segment of male rusty to sienna. Femora sienna to sepia, tibiae and tarsi terra-cotta. Scutellum and elytra dark slate blue to iron grey, with slight metallic blue tinge. Pronotum both in male and in female sometimes narrowly sienna bordered posteriorly, or with sienna spots in its posterior portion in female; in these cases also femora are paler and rusty, and only knees remain darker as in Fig. 34 .

Male. Eyes comparatively large, slightly reniform, moderately protruding, head across eyes as wide or slightly narrower than pronotum, head behind eyes straight, moderately narrowed posteriorly, head before eyes ca 1.5 times as long as length of eyes in dorsal view. Antenna reaching elytral midlength, last antennomere slightly constricted on one side at midlength. Frons very sparsely, vertex and head before eyes more densely punctate, covered by long recumbent white pubescence, semilustrous. Pronotum very slightly to moderately longer than wide, slightly to distinctly cordiform, its anterior margin straight to widely rounded, anterior corners rounded, lateral margins moderately to strongly sinuate, posterior corners rounded, posterior margin widely rounded, straight or shallowly emarginate in its middle part. Surface of pronotum punctate, disc very sparsely so, covered by white, recumbent pubescence, semilustrous to lustrous, with pair of rather deep depressions in its anterior portion. Elytra very slightly narrowing posteriorly, their surface imbricate-punctate, covered by white recumbent pubescence; matt, pubescence on scutellum and basal half of sutural margin of each elytron more or less distinctly denser. Last abdominal segment, tegmen and aedeagus as in Figs. 1-5 and 7 .

Female. Eyes smaller and less protruding than in male, head across eyes distinctly narrow- er than pronotum, antenna shorter, reaching about one third of elytral length. Last abdominal segment as in Fig. 6 .

Length J ♀: 4.8-8.5 mm.

Distribution. SW Russia: Dagestan ( ZAITZEV 1941), Azerbaijan, NW Iran, SW Turkmenistan (see also Fig. 8 ).

Comments. The type material of Probosca cinerea was not examined. However, the original description greatly agrees with the characters of Chitona fucata fucata and the locality is included in the range of this species.
