Exophthalmus scalptus Champion 1911

Oblong, narrow (♂), broader (♀), black; densely clothed (the head and rostrum more sparsely) with pearly-white scales (which sometimes have a cupreous or greenish tinge), the prothorax and elytra with small, scattered, bare—transverse, oblique, or foveiform—asymmetrically-arranged spots; the surface also set with minute, widely scattered, adpressed, setiform scales. Head and rostrum rather sparsely punctate, the rostrum short, about as broad as long, hollowed on each side of the stout, arcuate median carina, the latter followed by a small inter-ocular fovea, the eyes large and somewhat depressed; antennæ rather slender, the scape extending beyond the anterior margin of the prothorax. Prothorax transverse, convex, rounded at the sides, feebly bisinuate at the base; the spaces between the scattered, bare, irregular, foveiform depressions densely punctulate. Scutellum well developed. Elytra elongate-triangular in ♂, broader and widened to the middle in ♀, separately mucronate at the tip, the humeri not very prominent; interruptedly seriate-punctate, the interstices (except in the places occupied by the bare transverse marks) densely punctulate, 3 usually a little raised and the space between it and the suture flattened or depressed. Anterior tibiæ feebly denticulate and with a long claw at the tip.
 
Length 3—5, breadth 9½—13 millim. (♂ ♀.)

Fifteen examples. This species has the facies of a Compsus, but it is really related to E. impositus (Pasc.), having a similarly formed rostrum, &c. The irregular scattered bare transverse scratches on the prothorax and elytra give the insect a peculiar appearance; the eyes, too, are depressed, the rostrum short and arcuately carinate, and the vestiture of the elytra is so dense as to make the seriate punctures appear quite small.
