The paper deals with results of special fatigue life tests. Random processes of different power spectral densities loaded tube specimens made of a mild carbon steel ČSN 411523.1 (11523.1), notched by a perpendicular hole. It has been found that fatigue lives build similar S-N curves like by harmonic loadings, when the standard deviation s^d of peaks of an effective damaging stress and number of loading blocks Nb are used instead of amplitudes oa, and number of cycles Na, respectively. S-N curves of unaxial and multiaxial loading are compared in the paper.
A new genus, Coniophloeus gen. n., is described for five species of South African weevils known from the Western and Eastern Cape and assigned to the tribe Embrithini Marshall, 1942: Coniophloeus squalidus (Boheman, 1842) comb. n. (type species, transferred from the genus Trachyphloeus Germar, 1817 and tribe Trachyphloeini Lacordaire, 1863), C. alternans sp. n., C. oberprieleri sp. n., C. robustus sp. n. and C. obrieni sp. n. All five species are illustrated and keyed.
