Elytral intervals 3 with 1 setiferous puncture behind middle only. Head large and wide, at 0.87–0.94 times as wide as pronotum. Posterior angles of pronotum almost obtused, rounded on apex ( fig. 1 ). Antennae very long, at 3.2–3.6 times as long as pronotum. Striae of elytra delicate. Head brown, mouthparts reddish or yellow-brown; pronotum (except lighter narrow lateral margin) dark brown or reddish brown, sometimes with indistinct dark macula on the disk. Elytra with 1 2 3 large brown macula in apical two-thirds part (but schoulders, suture and narrow lateral margin of elytra — yellowish). Legs and antennae pale brown or reddish, the later often slightly infuscated from antennomere 3. Ventral surface of body dark brown, but abdominal sternites sometimes pale-reddish in the middle. .............................................................................................. 1.

Elytral intervals 3 with 3–5 setiferous puncture behind middle. Head small- er and distinctly at 0.75–0.89 times as narrow as pronotum ( fig. 2, 3 ). Posterior angles of pronotum almost right, acuted on apex. Antennae distinctly shorter, at 2.6–3.2 times as long as pronotum. 3 (4). Pronotum with sides already faintly sinuate or almost parallel in posterior third. Pronotum at 1.32–1.39 times as wide as pronotum on base, which almost equal to anterior margin ( fig. 2 ). Width of pronotum at 1.3 times more length. Eyes weakly convex. Antennomere 2 slightly shorter antennomere 3. 3.9–5.2 мм. Head and pronotum reddish brown, mouthparts pale-reddish. Elytra with large indistinct darkened macula. Legs and antennae yellowish, the later often slightly infuscated from antennomere 3. Ventral surface of body yellowish brown, ventral side of head and prosternum sometimes slightly darkened. ............................................................................................................. 2. A. transversalis (Shaum, 1862) . 4 (3). Pronotum with very rounded sides, distinctly narrowed posteriorly, only with a short sinuation before posterior angles ( fig. 3 ). Pronotum at 1.41–1.68 times as wide as of pronotum on base, which distinctly narrower than anterior margin. Width of pronotum at 1.36–1.43 times more as length. Eyes distinctly convex. Antennomere 2 at 1.5 or more times as short as antennomere 3. 3,8–5,1 mm. Head black, mouthparts reddish; antennomeres 1–2 reddish; pronotum from yellow-reddish to reddish-brown, disk usually darkened; elytra pale-reddish or yellow-brown with dark brown elongate macula, varying in size.
