Tyrosine, DOPA, DOPamine and N-acetyl DOPamine have been identified as the only phenolic substances occurring in the eggs or the house cricket, Acheta domesticus (L.). This is the first report or 2-diphenols in insect eggs known to the author. The quantitative variation and histochemical location of these substances indicate that they are involved in the formation of the serosal cuticle. N-acetyl DOPamine is probably the precursor of the quinone which tans the serosal epicuticle at the end or water absorption. Free DOPamine has been identified as the only free phenol in the extra embryonic fluid. The chemical identification and estimation of these aminophenols have involved some techniques that have not previously been applied to the study of tyrosine metabolites in insects.
