Amnestus pallidus Zimmer Annectus [sic] pallidus Zimmer, 1910, p. 166 Diagnosis. The almost concolorous reddish brown head, pronotum, scutellum, and corium, plus the shorter rostrum which does not reach hind coxae, will separate this species from all with five marginal pegs on juga. Body length 2.08 to 3.26 mm. This species is often confused with A. spinifrons (Say), but the shorter rostrum, which here does not exceed the hind coxae, will separate the two; or in males, the absence of a midventral angulation on the fore tibiae will mark it from A. spinifrons. Description. Tylus as long as juga, latter with five subequal, marginal pegs; surface, except tylus and apex of juga, coarsely punctuate; rostrum attaining middle of metasternum. Pronotum. Anterior margin shallowly concave, almost straight across; lateral margin straight on basal half; transverse impression obsolete, marked by vague row of punctures; anterior lobe with three to four irregular rows of moderate to coarse punctures laterally, subapically and along median band, calli mostly polished, with few fine punctures discally; posterior lobe, except umbones, with widely scattered punctures. Hemelytra. Mesocorium with few scattered, obsolete punctures discally; exocorium abundantly punctuate across full width. Prosternal carina lower than rostral segment II, rounded. Legs. Fore femora ventrally with premedian spine strong, oblique, unevenly bifid, and with blackish, subapical tubercle on posteroventral margin; fore tibiae neither angled nor spined mid-ventrally; hind femora not angled dorsally near apex, ventrally with subapical spine short, less than half height of femur.

Amnestus forreri Distant (Fig. 8 n) 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.

Champion; BCA., Hem 1, Amnestus stali Dist (type); so this specimen is designated as the Lectotype. The other specimen has the same labels, but also has a label: Distant Coll. 1911 - 383, and a yellow circled Paratype label; so this becomes a Paralectotype. New records. Mexico: Chiapas.

Type data. Although Distant (1893) did assigned type labels to the specimens (all females), the Holotype was not designated properly because there are two specimens mounted on one card. So here we assigned the specimen mounted on the right side of the card as the Lectotype, this specimen bears three labels: H.H.S. Mexico city; BCA., Hem 1 Amnestus bergrothi Dist (type); and a round red type label. The specimen on the left of the card is designated as a Paralectotype as well as the rest of the series. So there are three Paralectotypes with the same labels of the Lectotype; another Paralectotype from Teapa, Tabasco, Feb. H.H.S.; another from Pantaleon, 1700ft Champion. The specimens listed by Distant (1893) from Due��as and San Ger��nimo are lost and are not deposited in the Natural History Museum of London. The locality of the specimens here designated as Lectotype and Paralectotypes, cited as Mexico City, in our opinion are probable errors, because all other specimens of this species are from the south part of Mexico and Guatemala. Even though the type locality could be a mistake, the type locality is respected. New records. Mexico, Chiapas, Hoyo Don Nicho 8 mi N of Ocozocuautla, 16 -VIII- 1967, J. Reddell, 1 ♂.
