Extract

An account is given of a series of experiments on the feeding habits of Cryptophagus acutangulus, Gyll. It was shown that this species will feed readily on a wide variety of fungi and will only rarely ingest other foods. It thrived when fed exclusively on Penicillium conidia. C. acutangulus is capable of the internal mechanical and external transmission of fungi. Approximately 15 per cent. of the Penicillium conidia germinate after passing through the alimentary canal, and these conidia are so affected that they have an enhanced germination rate. The larvae feed exclusively on the spores and hyphae of fungi.

A complete life-history from egg to adult is given. The larvae and pupae are described for the first time, and a description of the adult is also given.
