Summary

Chromosome studies on 8 species of EuropeanCryptocephalus; C. aureolus Suffr.,C. capucinus Suffr.,C. globicollis Suffr.,C. hypochoeridis L.,C. moraei L.,C. rugicollis Ol.,C. sexpustulatus Vill., andC. violaceus Laich. have shown an identical karyotypic formula, 14II+Xyr, 2n=30. Most species ofCryptocephalus share 2n=30 chromosomes. The only interspecific differences are in the size of bivalents and in the sex-determining systems. The chromosomal interrelationships ofCryptocephalus with other allied groups are also discussed.
