 with variable epimerites; sporocysts open by simple rupture; sporoblasts 

 biconical, cylindrical, or navicular. 



21. Genus Sciadophora, Labbe (1899). The epimerite is large and flat- 



tened, protomerite umbrella-shape, with radiating ridges, sporo- 

 blasts biconical , gut of Phalangium sp. 



22. Genus Anthorhynchus, Labbe (1899). Epimerite in the form of a large 



grooved knob or button, sporoblasts ovoidal, pouated, gut of 

 Phalangium opilio. 



23. Genus Pileocephalus, Sclm. (1875). Epimerite lance-like or simply 



conical, sporoblasts biconical, different species in intestines of 

 Necrobia ruficollis, Blabera daraziana, and Mystacides of the Coleop- 

 tera, Orthoptera and Neuroptera respectively. 



24. Genus Amphoroides, Labbe (1899). Protomerite short and cup-like, 



epimerite a globular papilla, sporoblasts curved, gut of myriapods. 



25. Genus Discorhynchus, Labbe (1899). Protomerite larger than deuto- 



merite which is cylindrical and truncated posteriorly, epimerite large 

 and globular with a thin collar around the base, cysts spherical; 

 sporoblasts biconical and slightly bent; gut of neuropteron, Seri- 

 costoma sp. 



26. Genus Stidospora, L^ger (1893). Epimerite with globular head de- 



pressed ventrally and covered with ribs which project posteriorly 

 as spikes; sporoblasts biconical and slightly curved; intestines of 

 species of Melolontha and Rhizotrogus larvae. 



27. Genus Sdineideria, Leger (1892). Gamonts without protomerite; 



epimerite a thick plate bordered by rib-like thickenings ; sporoblasts 

 biconical; intestines of Bibio marci and Sdara nitidicollis larvae, 

 Diptera. 



28. Genus Asterophora, Leger (1892). Epimerite a circular disc with ribs 



surrounding a prominent central style; sporoblasts cyhndrical with 

 conical ends, intestines of insect larvae. 



29. Genus Bothriopsis, iichn. (1875). Epimerite an ovoidal structure with 



six or more long slender filaments; individuals motile; transverse 

 septum convex anteriorly; sporoblasts biconical, gut of Hydaticus 

 dnereus. 



30. Genus Coleorhynchus, Labb^ (1899). Protomerite a circular shallow 



disc depressed sucker-like in center, the septum projects into the 

 protomerite, sporoblasts biconical or navicular, gut of Nepa dnerea. 



31. Genus Legeria, Labbe (1899). Protomerite enlarged and club-like with 



invading septum as above , j^ sporoblasts sub-navicular, gut of 

 Colymbetes sp. 



32. Genus Phialoides, Labb^ (1899). Complex stalked epimerite consisting 



of a discoid retractile cap surrounded by a circular ridge with a 

 collar-like membrane and with ridges ending in triangidar teeth, 

 sporoblasts biconical, gut of Hydrophilus larvae.
