LUCANUS

(Yunanca köken — orijinale bakınız.) A Linnsan genus of Coleoptera, forming the type of a tribe of Lamellicorn beetles {Lucanina), in the system of Latreille, by whom it is thus characterised: — Antennae composed of ten joints, the first of which is usually much the longest; the antennal club has its leaflets or teeth arranged perpendicularly to its axis, in the manner of a comb. The mandibles are always corneous, and most commonly exhibit a sexual superioritv of development and peculiarity of form in the males. 'The maxillae are generally terminated by a narrow, elongated, and silky lobe; but sometimes are entirely corneous and dentated. The ligula in most of the Lucanines is formed of two small silky pencils, projecting more or le beyond an almost semicircular or square mentura. The anterior legs in the greater number are elongated, and their tibiae dentated along the whole of their outer side. The tarsi terminate in two equal and simple hooks, with a little appendage with two setae between them. The elytra cover the whole of the upper part of the abdomen. The insects thus characterised were first divided by the immediate succe ors of Linnaeus into two genera, Lucanus proper and Pa alus, both of which are now elevated to the rank of families, and subdivided into numerous subgenera. See LucANiDjE and PA ALi DiE. [s. 699] A Dictionary of Science, Literature, and Art — W. T. Brande (1st Ed.) ana Sözlük (A–Z)
