Abstract
The coccidian dealt with in this paper is a parasite of the blood, fat bodies and connective tissue ofTribolium ferrugineum. W. A. Riley and L. Krogh were the first and perhaps the only ones who noticed stages of this parasite, when studying the histology of the larvae of this beetle. They found the pupae and adults uninfected, but in the course of the present work some of them were heavily infected, though only a small number could be examined.
