FROM VARIETIES AND ABERRATIONS OF RHOPALOCERA FAUNA OF THE BAKONY MOUNTAINS, Part I. Analysis of the applied definitions In the introduction of this first part I have to speak shortly from last decades'deviations researches. I analysed critically in a few words, that the described aberrations' unnecessarying in what size presented in the teipdopterological literatur. Moreower, the used of these definitions, weren't generally exact and true. For example, in more comprehensive works, the authors continually using the ,form" locution for all irregular specimens. In opinion of aberrations and varieties also there arent not concord. Very common case, when the researcher put sign of equality, in between the two definitions. Therefore I have thought, that we have to clear up the usage of these. Here only shortly: Varieties They are such irregular specimens, which occur within the area of nomenclatural and subspecifical primarily described populations. In these cases there are not individual, external effects and this varyied morphological aspect, is always hereditary, such genetical consequence. Aberrations Mostly, the consequences of the climatical and the different moistly parameters. The morphological symptoms occuring generally on the ground colour, and in the drawings. These différents are exclusively individual and there are not hereditary. Melanism In the case of melanism on all wings, rarer or only forewing, with more dark scales visible than on normal drawing. The melanims is not genetical process and not hereditary. Albinism Due to a reduction or occasionally absence of dark and black pigments are reduced to mauwish grey or whitish-grey. Occurs mostly the Argynninae, Satyridae families and in species of the Lycaenidae tribe. L e u ci s m Incorrect expression, but use in the practice. In fact, contrast with melanism, when the dark pigments reduced. Examples from Bakony: Clossiana selene, euphrosyne, but mostly only at marginal bands. Gynandromorphism In this case shows indications of both sexes apparent in one specimen. In earlier times there specimens were described as hermaphrodities. Naturally this idea is not correct. Occur in the Bakony Mountains on the species Of Plebeius, Lycaeides and Lysandra genera. Homoeosis Altough mostly very rare and in our area yet did not occur. Its' very few specimens known only from British Islands. The homoeosis visible on Satyridae and Pieridae, where the markings of wings and areas of ground colour of the forewing may be reproduced on the hindwings. Mutations It is also incorrect application, because this is a quick varying and the cause still unknown. That is sure, the mutation genetically continue and generally harmful. It stands in loose connection with varieties throughout on chromosomatical changes (translocation,reduplication etc.). This mutation' process lasts to while the back-mutation will begin. Finally, the end of this first part visible, - on illustrations too, - four freshly described abberations which yet did not occur in lepidopterological literature. The four species are the following. Pseudophilotes vicrama schiffermiilleri HEMM. ab. dahlstroemi ab. nova Lysandra coridon PODA ab. erythiana ab. nova. Melitaea britomartis centroposita ISS. & KOV. ab. cymothorina ab. nova Coenohympha arcania cephalus Geoffroy ab. cessexa ab. nova.
