Abstract
The C-banding pattern and Ag-NORs in the karyotpye of Bembidion lampros and Bembidion properans are presented. The results indicate that in chromosomes of the examined species the constitutive heterochromatin is located in the proximity of the centromeres. In B. properans the paracentromeric C-bands are similar in size. In B. lampros a large heterochromatin segment occurs on the 1st pair of autosomes and on the X chromosome whereas the other autosomes have shorter paracentromeric C-positive blocks but all nearly the same size. In mitotic stages, from the prophase to the prometaphase stage one silver dot on the end of two autosomes is visible. In prophase I (to diakinesis) one active NOR is observed.
