than transversely; much wider than thorax, gradually widening towards posterior 2/3, thence gradually narrowed; apex not pointed; humeral callus prominent; base of elytra a little swollen, concave, so receiving scutellum, what seems a peculiar feature of this species of Cyrtosoma; striae deep, extending from base to apex, with no trace of punctures; interstriae smooth and shining, flat near suturai margin, slightly concave toward sides. Ventral surface dull in thoracic portion, abdominal ventrites shining. Prosternai process lanceolate, prolonged caudally extending to intercoxal process of mesosternum. Mesoventrite short, metaventrite long, with very thin midlongitudinal sulcus. Abdominal ventrites 1 to 3 shining, with dense and strong punctation tending to form longitudinal striolae, last two ventrites completely smooth. Legs long, slender,- smooth, tibiae very slightly curved, last tarsomere as long as the preceding together; claws very long. Length 10 mm. Type material - Holotype sex unknown (HNHM): "Sto Paulo Amazones M de Mathan 8bre9brc 1879"; "Slg. R. Oberthür Eing. Nr. 4, 1956"; "Cyrtosoma sp. det. Kaszab". Distribution - Brazil. Remarks - The large angulosity on the anterior half of the pronotum is different from all species of Cyrtosoma known to author. Cyrtosoma novagranadae sp. n. (Fig. 6) Description - Wingless, black (Fig. 6); elytra short, subovate barely dilated posteriorly, pronotum much narrower than elytra. Head transverse, closely but very minutely punctate; clypeus short, slightly emarginate anteriorly; frontoclypeal suture shallow; genae with rounded sides, convex, prominent; eyes slightly wider than genae; labrum well developed, covered with golden pubescence. Pronotum transverse, broadest at middle, much more convex transversely than longitudinally; surface with rather close, but extremely minute punctation, so that almost shiny; sides rounded, sinuate before posterior angles, base narrower than apex; posterior angles rectangular; lateral and basal margins bordered, except median part of basal margin; apex slightly emarginate, base slightly bisinuate. Elytra with maximum width at posterior 2/3; striae very fine on disc, deeper toward sides and apex, impunctate; interstriae flat, except for 9th a little convex; surface with extremely minute, barely visible punctation; epipleura impunctate; apex not prominent. Legs short and relatively thick. Ventral part of thorax and abdomen smooth and shining. Length 8 mm. The poor state of conservation of the only available specimen prevents any more accurate examination. Type material - Holotype, sex unknown (HNHM): "Colombie"; "coll. R. Oberthür ex coll. Deyrolle", "Cyrtosoma melanarium Dej."; "aff. freudei Marc. det. Kaszab". Distribution - Colombia. Remarks - The affinities could be looked for in Cyrtosoma trinitatis MARCUZZI, 1976 (Trinidad) and Cyrtosoma freudei MARCUZZI, 1976 (Colombia). The new species is different from them because of smaller size, with head, pronotum
