Amnestus forreri Distant, 1893 , p. 452

Diagnosis. This species can be distinguished from others with five marginal pegs on juga, by the numerous distinct punctures on the pronotal umbones and having most of the disc of the calli coarsely and closely punctuate similar to the lateral parts of the anterior pronotal lobe. It is similar to A. cribratus , but they may be separated, because A. cribratus has the prosternal carina concave ventrally with a strong triangular lobe anteriorly, while A. forreri has the ventral margin of the carina virtually straight. Body length 2.82 to 2.96 mm.

Description. Head. Most of head, anterior lobe of pronotum, scutellum, and most of ventral surface yellowish brown; posterior lobe of pronotum, clavi, coria and appendages yellowish.

Head. Tylus surpassing juga by a distance equaling one-half of its own width; surface coarsely and closely punctuate, except on tylus and apical halves of juga; juga with five marginal pegs. Rostrum reaching almost the bases of middle coxae. Anterior margin of pronotum very feebly concave, cupped behind eyes; lateral margins sinuate near base; transverse impression weak except laterally, marked by a row of coarse punctures; anterior lobe with broad band of coarse punctures laterally and subapically and with numerous close-set moderate punctures along midline and over most of calli; posterior lobe, including umbones, with very numerous, close-set punctures becoming finer posteriorly. Hemelytra. Mesocorium impunctate except for two rows paralleling claval suture; exocorium distinctly and strongly punctuate virtually to costa. Prosternal carina higher than rostral segment II, anterior margin roundly perpendicular, ventral margin straight and almost horizontal, posterior end lower but abruptly terminated. Legs. Fore femora ventrally with premedian oblique spine very unevenly furcated and with subapical small tubercle on posteroventral margin; anterior tibiae ventrally neither angled nor spined at middle; hind femora ventrally with subapical spine stout, oblique, shorter than height of femora, subequally furcated at apex, dorsally with subapical angulation. Paramere as in figure 8n.
