Abstract

The female reproductive system of Pachylophus proximus Adams (Chloropidae) is descriptionbed, with additional notes concerning two other species of the genus. In these species one ovary is atrophied, and the other is reduced to a single ovariole. In addition, one large egg is retained in the terminal part of the reproductive tract (uterus) until a fully developed first instar larva develops within the chorion. The female reproductive system of several undescriptionbed species of Cyrtona Séguy (Curtonotidae), with its brood pouches, is descriptionbed and illustrated. The brood pouch retains a number of eggs after fertilisation, and the first instar larvae are kept there until deposition.
