Gametogenesis is completed in the pupa in both sexes and the gonads degenerate in the non-feeding adult.
Cyst wall cells, which act as trophocytes, accompany each cyst from an axial germinal region to the radiating follicles. A preliminary account is given of a fibrous structure, the lens of Demokidoff, which overlies the germinal region in the testis lobe.
The morphology of the gut and gonads of the male Ochrocydus huttoni are briefly described.
A distinction is drawn between the reproductive patterns of the subfamilies Prioninae and Lamiinae. In the former, where a non-feeding adult is characteristic, gametogenesis is completed in the pupa, after which the gonads degenerate, while in the Lamiinae, where the adult feeds, gamete production continues through adult life. Between these extremes, the Cerambycinae and Aseminae appear to tend toward the prionine condition, and the Lepturinae toward the lamiine.
