Exophthalmus albovittatus Champion 1911

Oblong, rather narrow (♂), broader (♀), black; above somewhat thickly clothed with small green or greenish-olivaceous scales, the prothorax with a denser submarginal vitta of pure white imbricate scales on each side, these stripes being continued down the disc of the elytra to near the apex, the scales around the eyes, along the lower margin of the elytra, and on the body beneath white, or, like those on the legs, white intermixed with green. Head and rostrum rugulosely punctate, the rostrum broad, a little longer than wide, obsoletely carinate, not or feebly foveate between the eyes, the latter rounded and moderately convex; antennæ rather slender, the scape not extending beyond the eyes. Prothorax broader than long, narrowed anteriorly, feebly bisinuate at the base, slightly hollowed or interruptedly canaliculate down the middle, and with a transverse depression opposite the scutellum; densely, rugulosely punctate. Scutellum small. Elytra subparallel for a short distance below the base in ♂, much broader and widened to the middle in ♀, flattened on the disc anteriorly, conjointly acuminate at the tip, the humeri not very prominent; rather finely punctate-striate, the interstices feebly convex and densely rugulose.
 
Length 10 1/5—12, breadth 3 2/5—4 1/5 millim. (♂ ♀.)

Hab.GUATEMALA, Quiché Mountains 7000—9000 feet (Champion).

One pair. This species may be known by the dense pure white stripe extending down the disc of each elytron from the submarginal vitta on the prothorax, the rest of the scales on the upper surface being less crowded and green or olivaceous in colour. The scutellum is small and the humeri not very prominent. The rostrum is much broader and the humeri less prominent than in the Mexican E. duplicatus.
