EGG MORPHOLOGY IN SOME PSELAPHIDS (Coleoptera) On the basis of materials obtained in laboratory, eggs of 13 species, 5 tribes, have been examined, and nine egg forms have been recognized. According to species, morphological variability affects: l) egg shape (spherical, sub- spherical, ellissoidal, egg-like), 2) corion structure (smooth, wrinkled, pimpled, reticulate), 3) presence of a tubercle, 4) presence of a filament, 5) colour (milk-white, whitish, ivory- or amber-coloured). Very characteristic feature of Pselaphus heisei is a fluid droplet (? mother's secretion) that covers every egg. Both inter- and intrageneric variability has been found. Viene documentata la variabilità morfologica delle uova in tredici specie di Pselafidi di cinque tribù. Essa si esprime nella forma complessiva dell'uovo, la struttura del corion, la presenza o meno di una parte filamentosa. Di molto particolare le uova di Pselaphus heisei presentano una sorta di protezione fluida che ricopre le singole uova
