Karyological studies were carried out on seven Palaearctic weevils. The following chromosome numbers were found in individual species, i.e. Otiorhynchus niger (F.), Phyllobius viridearis (Laich.), Phyllobius scutellaris Redt., Phyllobius calcaratus (F.), Polydrusus cervinus (L.), and Brachyderes incanus (L.) 2n=22, n%=10+Xyp, in Lixus elegantulus (Boh.) 2n=22, n%=21+Xyp. The heterochromosomes of all the examined species form, in the first meiotic metaphase, a typical parachute bivalent.
