Eryphus Perty, 1832 and Tacyba, a new genus of Heteropsini (Coleoptera, Cerambycidae). Some species, up to now, included in Callideriphus Blanchard, 1851 are rearranged in: a) those congeneric with Callideriphus grossipes Blanchard, 1851 and b) not congeneric. The first set of species will be treated in a future paper; the second one, on the other hand, is subdivided into Eryphus Perty, 1832 and Tacyba gen. nov. Eryphus Perty, 1832 (type species: Eryphus bipunctatus Perty, 1832), a valid genus, is redescribed and a key for the species is also provided. The following species are transferred to Eryphus: E. bivittatus (Melzer, 1934) comb. nov., E. carinatus (Zajciw, 1970) comb. nov., E. flavicollis (Fisher, 1938) comb. nov., E. laetus (Blanchard, 1851) comb. nov., E. marginatus (Zajciw, 1970) comb. nov., E. picticollis (Gounelle, 1911) comb. nov., E. transversalis (Fairmaire & Germain, 1864) comb. nov. New synonym proposed: Eryphus bipunctatus Perty, 1832 = Callideriphus atricollis Melzer, 1931. New taxa described: Eryphus tacuarembo sp. nov. (Uruguay, Tacuarembó), E. carioca sp. nov. (Brazil, Rio de Janeiro); Tacyba gen. nov. (type species: Callideriphus maculatus Cerda, 1988). Species transferred to Tacyba and synonyms: T. maculata (Cerda, 1988) comb. nov., T. tenuis (Blanchard, 1851) comb. nov. = Callideriphus testaceicornis Fairmaire & Germain, 1859 syn. nov. = Callideriphus clathratus Fairmaire & Germain, 1860 syn. nov. = Callideriphus niger Philippi & Philippi, 1864 syn. nov. Callideriphus flavicollis m. quadripunctatus Fuchs, 1961 and Callideriphus flavicollis m. reductus Fuchs, 1961, both names of infrasubspecific category (not available under the rules of ICZN), are herein treated as intraspecific variation of Eryphus picticollis (Gounelle, 1911) which occur in southern Brazil and Argentina.

Effect of ninfal density of Aphis gossypii Glover, 1877 (Hemiptera, Aphididae) on feed consumption and biological aspects of Orius insidiosus (Say, 1832) (Hemiptera, Anthocoridae). The influence of different densities of A. gossypii (10, 20, 30, 40, 50, 60 nymphs/day) on consumption rate, development time, survival, and reproduction of Orius insidiosus (Say, 1832) was investigated. The trials were carried out in climatic chamber at 25 ± 1 °C, 70±10% RH, and photoperiod 12:12h (L:D). Consumption rates of nymphs and adults increased under a linear form as the densities of aphids increased. Development time was longest when reared in 10 nymphs density (15.4 days). Nymphal survival was different under the densities of A. gossypii and no significant difference for the periods of preoviposition (4.8 days) and oviposition (8.9 days) were found. The oviposition increased with the prey densities (2.00, 11.33, 10.67, 21.30, 17.89 and 53.38 eggs), as well as the viability: 0.00, 52.49, 57.86, 58.14, 50.11 and 72.89%, respectively. Nymphs of A. gossypii as prey were suitable for the complete development of O. insidiosus.
