Abstract: The anatomy and histology of the male and female reproductive systems of Lycormadelicatula White are described in detail. It is found that the six sperm tubes of the testisare not bound together by a common scrotum, and the ovary is composed of fourteentypical telotrophic ovarioles. The secretions of various subdivisions of the male accessorygland have been identified by histochemical methods as the seminal fluid, the spermato-phore and the spermatophylax respectively. The misinterpretations of some parts of thefemale genital system in previous literatures have been corrected. The so-called femaleaccessory glands are found to be the spermathecum and its glands and the misidentifiedspermathecum is found to receive and to digest the spermatophore and is therefore thebursa copulatrix. Intracellular canaliculi are found in the gland cells of the spermathecalglands, which open into the lumen through the intima. The inner layer of the epithelialfolds of both the corpus bursae and the cervix bursae are found to be composed ofglandular cells, which may secrete a kind of enzyme (or enzymes) to digest the spermato-phore. The secretion is also discharged into the lumen via the canaliculi. Based upon therelationship between spermatophore fertilization and the rate of vitellogenesis, the signifi-cance of the spermatophore as a proteinaceus nutrient for the nutrition and reproductionof the female insect is discussed.
