|Abstract||Length 2 mm., breadth 1 mm. — Oblong, rather broad, slightly convex, but little glossy, of a reddish testaceous colour, provided with a large elongated brown spot on the middle of each elytron, and covered with a very fine and short greyish pubescence; the elytra show moreover a second pubescence which is recumbent, fine and white, covers the base and the extremity, and forms an M- or zigzagshaped band. — Head closely punctured, broad and thick, a little convex on the vertex; eyes black, large, prominent, reaching almost to the posterior border, sinuated in front, rather approximate on the fore-head. Antennae reaching beyond the shoulders, the first joints slender and oblong, the 3rd a little smaller than the 2nd, the following ones a little broader and transverse, the apical joint obtuse oval. — Prothorax punctured in the same way as the head, narrower than the latter and having nearly the shape of a transverse square, truncated anteriorly with rounded angles, hardly narrowed in a curve on the sides, slightly emarginated at the middle of the base with rounded angles and with a feeble depression before the scutellum. The latter is small and rounded. — Elytra rather strongly punctured, subparallel obovate, broadly rounded at the apex, truncated at the base and much broader than the prothorax, the humeral angles raised, rounded, the small swellings rather distinct. — Legs slender, posterior femora but little thick.|
To a certain extent this species resembles X. populneus with respect to the size and facies, but the zigzaglike design of the pubescence on the elytra and especially the disposition of the 2nd and 3rd antennal joints distinguish it at first sight.
