ROVARTANI KÖZLEMÉNYEK (SERIES NOVA) TOM. XXIII. 1970. Nr. 3. A Comparative Anatomy of the Insect Head I. Muscles and Nerves of the Regio verticalis, R. antennalis and R. labralis By Dr. H. Steinmann Hungarian Natural History Museum, Budapest The typical insect head is discussed rather briefly in the entomological handbooks. Details may be had from larger and comprehensive works, e.g. SNODGRASS's or WEBER's, but these authors had studied its morpho- and organology in all cases as an accumulation of examples or in the mirror of exceptions hence there is no possibility give

n to obtain a uniform nomenclature concerning the typical insect head. One of the main objectives of the present series of papers is therefore to establish the common characteristics of the insect head,to summarize the typical and thus to serve as a basis for the anatomist when demarcating the differentiated from the common or typical.I have summarized all which is common and typical for the insect head in the mirror of the musculature and the* central nervous system. Both organ systems reflect concurrently also a common basic pattern from which the single types deviate merely by morphological or numerical features. The purpose of the work is thus twofold: first to submit a generalization for students who are interested only in the general and characteristic and secondly a typified picture for those who, availing themselves of this basis, propose to study measurable deviations leading from the general to the individual.
