โฆ Synopsis
The large heterochromatic chromosome of Drosophila nasutoides reveals distinctive C- and Q-bands. The regions which are negative in C-banding appear positive in Q-banding. The isochromosomic nature of this chromosome and the locality of the satellite DNAs in this chromosome are discussed with respect to these banding patterns.

A phenotypically normal male has a small Y chromosome with no Yq fluorescence, but displays constitutive heterochromatin on the end of Yq. C and Q bands on Yq therefore need not be necessarily identical.
Q-, C-, and G-banding patterns are described for the germ-line and somatic chromosomes of Miastor sp. The chromosome number in the germ line is 36, which is 3 less than that previously reported for the same cultured line 18 years ago. There are 8 chromosome groups: 8 large acrocentrics, 11 large and
