Simocephalus vetulus (O. F. Müller) is coloured by carotenoids, which may befree in globules in the gut wall and fat body, or associated with proteins in the cytoplasm of the fat cells, carapace epidermis, ovary and eggs. A green carotenoprotein is foundin the blood. The transfer of carotenoids from one tissue to another is described; these pigments can be excreted via the gut in fully developed embryos. An intermoult cycle, related to egg laying is shown to cause variation in the pigmentation of the fat cells, carapace and blood.
