✦ Synopsis
Female and male first meiotic prophase are analyzed in the grasshopper Arcyptera microptera with special reference to the heteropycnotic chromatin. Differences in the behaviour of the megameric and X-chromosomes, in nuclear size and in the response to C-banding treatment are described. The evidence for a distinctive meiotic prophase in both sexes is compared with results obtained in other species of grasshoppers by other authors using more advanced stages. The discussion centers around the role of the diffuse stage and the differential behaviour of the Xchromosome in the two sexes.
