1 (4) Antenna with last 4 segments expanded to form a feeble club (Figs 13, 14). 2 (3) Surface of elytral epipleura with coriaceous ground-sculpture, without distinct puncturation. Anterior angles of male's pronotum not retracted 1st Group 3 (2) Surface of elytral epipleura shining, with only very fine microscopical ground-sculpture or smooth, separated punctures visible. Anterior angles of male's pronotum retracted 2nd Group 4 (1) Antenna with last 5 segments expanded to form a feeble club (Fig. 12) 3rd Group * Coprophilus (Zonoptilus) schubertii Motschulsky, 1860 The unusually laconic original description of the author was cited by FAUVEL (189 7), LUZE (1904), REITTER (1894) and they have shown its incompleteness. When I had seen the types - to my great surprise - the published comparative measurements proved to be erroneous, thus, the length of types 4-4.2 mm did not reach the smallest length of C. striatulus (F.) (5-7 mm). Considering that C. striatulus (F.) was a wellknown species to MOTSCHULSKY, his erroneous establishment is totally inconceivable to me. This error made the species unrecognizable, for more than 100 years and became a source of some subsequent misunderstandings. I think it necessary to redescribe the species on the basis of its types, giving the differential diagnosis between it and the very similar C. piceus Solsky, 1867: Head, pronotum and abdomen shining black, elytra dark reddish-brown, anterior margin of clypeus, labrum, palpi and legs rusty-red, mandibles reddish-brown darkened apically, the first 2 segments and the 8th to 11th of antennae pale rusty-red, 3rd to 7th segments dark, reddish-brown, the last segment of maxillar palpi partly brown. Head broader than long (27: 12), with compound eyes broader than pronotum between anterior angles. The compound eyes are large, rather prominent. Anterior margin of front above the insertions of antennae forming small, shining tubercles, and between surface of the front rather shining with only a few punctures, at internal side of tubercles 1 round pit-like fovea. Head behind compound eyes with a moderately shallow, curved, transverse furrow, upper surface covered with very fine coriaceous microsculpture and on front with scattered, on vertex and neck with more dense puncturation, under surface - especially postocular region - coarsely shagreened and very densely and confluently punctured. Antenna with thick and large 1st segment, 2nd and 3rd elongate, equal in length, but the 3rd somewhat more slender than 2nd, 4th and 5th scarcely longer than broad, equal in length, 6th and 7th as long as broad, 8th to 11th larger than the former ones, transverse with fine but dense pubescence and some longer setae, separated as a 4 - segmented loose club (Fig. 13). Pronotum transverse, broader than long (34:28), broadest on the middle, sides by gently curving narrowed anteriorly, but in nearly straight line strongly narrowed posteriorly to the obtuse-angular posterior angles. Anterior edge without margin, nearly straight, anterior angles briefly rounded and somewhat produced forrds, sides margined, edge of base curved and margined. Disc arched, from the middle of si«_ s 1 hardly visible, feeble, longitudinal impression extends backwards near to margins and 2 small, ovoidal foveae near base on either side of the middle, surface rather shining, covered with scattered, moderately deep puncturation. - Scutellum shield-like, elongate, rounded apically, margins shining, disc shagreened, coarsely punctured, less shining. Elytra together broader than long (48:40) and distinctly longer than pronotum, a little widened backwards. Humeral angles slightly produced forwards, postero-external angles widely rounded, apical edges extending inwards to the scarcely rectangular suturai angles. On disc 5 punctato-striae extend between humeral knob and suturai edge, not reaching the apex, confluent among irregular puncturation. Interspaces moderately arched, surfaces smooth and shining Original description of the author: "Le genre Zonoptilus des Oxytelides, que j'ai décrit et figuré dans le Bull, de Mose. 1845 et 1858, vient d'être enrichi par une seconde espèce européene du Gouv. Voronesch, ou M. le Dr, Schubert l'a décuverte, et que je me fais un plaisir de lui dédier en la nomant Zon. Schubertii. Elle est de la taille et des couleurs du Coprophilus striatulus F., mais se distingue par son corselet convexe sans aucune impressions. "
