Extract

This gregarine was found inhabiting the alimentary canal, and especially the midgut, of both larvae and imagines of Anobium paniceum. All the larvae examined, and most of the adult beetles, were found to be very heavily infected, and in some of the larvae almost every epithelial cell harboured one or more of the cephalont stages of the parasite (Fig. 1). The lumen of the midgut of these larvae was densely packed with the freely moving sporonts, and a number of newly formed cysts were visible in the hindgut. In the imago only the cephalont stages were observed, and no sporonts or cysts have been found.
