Extract

Cis Bidentatus, which acts as host to this gregarine, is a small fungus-eating beetle. Almost all the beetles examined proved to be infected, but the parasites were never very numerous in each host. As a rule the infected beetles contained from four to eight of the sporont associations, and sometimes a few of the cephalont stages or cysts. The adult gregarines may be seen by transparency through the wall of the mesenteron: they lie either straight or else bent in the form of a U, but always with their long axis parallel to the sides of the gut. They are restricted to the posterior region of the midgut, and are never distributed along its whole length.
