Blackish, front angles of pronotum vaguely reddish; legs brownish-red; antennal club blackish (typical color pattern, Fig. 17 View Figure 11-20 ); sometimes elytra yellowish with several small blackish spots (color pattern of A. euprosopus Bates, 1887 , Fig. 12 View Figure 11-20 ), or elytra basally yellowish with small blackish spots on the distal half, with a wide blackish band, apex yellowish ( Fig. 13 View Figure 11-20 ), or elytra basally blackish posteriorly with two oblique bands of small blackish spots each other joined by opposite angles ( Fig. 14 View Figure 11-20 ), or elytra with three oblique bands of small blackish spots each other joined by opposite angles (color pattern of A. multimaculosus Hinton, 1934 ; Fig. 15 View Figure 11-20 ), or elytra blackish with juxtasutural interval, lateral margins and apex yellowish ( Fig. 16 View Figure 11-20 ). Head with epistome feebly gibbous, distinctly regularly punctured; clypeus sinuate at middle, subangulate at sides, thinly bordered, edge feebly upturned near front angles; genae obtusely rounded, sparsely shortly ciliate, protruding more than eyes; frontal suture feebly trigibbous; frons distinctly evenly punctured. Pronotum transverse, moderately convex, dually punctured, with narrow impunctate longitudinal area on disc; large punctures, two to three times larger than small, irregularly sparse, denser on sides; small punctures rather evenly scattered throughout; lateral margins nearly straight, distinctly bordered, edge glabrous; hind angles obtusely rounded; base faintly bisinuate, distinctly bordered. Scutellum distinctly punctured on basal two thirds. Elytra oval, convex, denticulate at humerus, distinctly striate; striae punctured, feebly crenulate; intervals flat, the discal ones densely punctured, the lateral more coarsely punctured, with extremely short and sparse hairs toward apex. Hind tibiae superior apical spur shorter than first tarsal segment; latter nearly as long as following three combined. Male: head and pronotum relatively more transverse, less convex and less densely punctured; frontal suture distinctly trigibbous; aedeagus Fig. 19-20 View Figure 11-20 . Female: head and pronotum relatively less transverse, strongly convex and densely punctured; frontal suture with gibbosities nearly obsolete.
