Unabiara, a new genus of Heteropsini Lacordaire, 1869 (Coleoptera, Cerambycidae). Unabiara gen. nov. is proposed to include Callideriphus collaris Philippi & Philippi, 1864 (type species); provisionally it is maintained in Heteropsini Lacordaire, 1869. Unabiara collaris (Philippi & Philippi, 1864) new combination, is redescribed and illustrated, including the mouth pieces, endosternites, wing venation and male and female terminalia.

The genus Physopleurus Lacordaire, 1869 = Basitoxus (Parabasitoxus) Fragoso & Monné, 1995 syn. nov. is revised and redefined based on new characters. The following species are treated (in sequence that appear in the presented key): Physopleurus exiguus sp. nov. (Bolivia and Brazil), P. crassidens (Bates, 1869), P. longiscapus Lameere, 1912, P. rugosus (Gahan, 1894), P. tritomicros Lameere, 1912, P. seripierriae sp. nov. (Brazil, Mato Grosso), P. dohrnii Lacordaire, 1869, P. villardi (Lameere, 1902) = Aplagiognathus guatemalensis Casey, 1912 syn. nov., P. amazonicus (Fragoso & Monné, 1995) comb. nov., and. P. maillei (Audinet-Serville, 1832) comb. nov. The latter two species formerly in Basitoxus (Parabasitoxus) Fragoso & Monné, 1995. Illustrations of Basitoxus megacephalus (Germar, 1824) are included to allow comparisons with Physopleurus species. Key to species of Physopleurus is added.

In this article two aims are pursued: on the one hand, to present arapidly converging algorithm for the approximation of square roots; on theother hand and based on the previous algorithm, to find the Pierce expansionsof a certain class of quadratic irrationals as an alternative way to themethod presented in 1984 by J.O. Shallit; we extend the method to findalso the Pierce expansions of quadratic irrationals of the form $2 (p-1)(p - \sqrt{p^2 - 1})$ which are not covered in Shallit's work.

The experiment was conducted at the Aquaculture Station “Amazonia Aquaculture Service”. We worked with 13 females and 16 males. The main objectives was the inducing breeding with carp pituitary extract. All females spawned, however, five females with negative results on fertility. In an average temperature of 28.12±0.61 °C, it takes 5.68±0.53 hours for spawning or 159.01±14.45 hours-grade. The females of 4 years of 2310±143.2 g, fertilization rate achieved, over 66% on average 1497.60±14,57 eggs are per gram, fertilization and hatching rate of 68.80±1.9% and 53.59±8.7% respectively. Hatching occurred at 11.67±0.32 hours, the water temperature was 28.25±0.09 °C, so that the hatching 331.07±12.56 required hour’s degree.
