The morphology of the chromosomes of the grasshopper, Zonocerus variegatus was studied from mitotic metaphase and meiotic stages in squashed preparations of fresh testicular material. The chromosomes (2n_??_=19) were found to be acrocentric as in most of the Pyrgomorphidae and not metacentric as reported in one study. No meiotic aberrations were detected.
