The heterochromatin of three species of the montium subgroup of Drosophila, namely, D. nagarholensis, D. jambulina and D. kikkawai has been analysed. Within the basic karyotypic configuration of 2n = 8, interspecies differences in the pattern and the intensity of C-and Q-band heterochromatin particularly of Y and dot chromosomes have been recorded.
