Exophthalmus albofasciatus (Champion 1911)

Oblong, shining, black; the prothorax with two narrow interrupted vittæ on the disc, and the elytra with three irregular fasciæ, a transverse patch at the base, and various scattered asymmetrically arranged spots, densely clothed with white or yellowish-white imbricate scales, the rest of the upper surface more sparsely set with minute, brown or whitish scales and very short decumbent setæ; the under surface and legs with small bluish or white scales. Head and rostrum closely punctate, the head foveate between the eyes, the rostrum much longer than the head, sharply carinate down the middle, and sulcate on each side in front of the eyes. Prothorax transverse, subconical, rounded at the sides anteriorly, more or less distinctly sulcate down the middle; very sparsely, irregularly, coarsely punctate, the interspaces minutely punctured. Elytra with rows of closely placed coarse punctures, which become crowded and confused on the outer part of the disc below the base, the interstices almost flat, the apices feebly acuminate, setose, and dehiscent. Tibiæ without denticles on their inner edge.
 
Length 15—17, breadth 5¼—7¼ millim. (♂ ♀.)

Hab.HONDURAS (Mus. Brit.: ♂), Belize River (Stanton, in U. S. Nat. Mus.: ♀).

Two specimens, the male labelled as having been received in 1845. In the latter the prothoracic sulcus is sharply defined and the seriate punctures on the disc of the elytra are very coarse. The minute whitish scales on the upper surface are easily abraded, but when present (as in the female) they give a powdery appearance to the spaces between the markings. The deciduous portion of the mandibles is flattened and falciform (fig. 23 a).
