PROTOZOA WITHOUT MOTILE ORGANS 61 



Group D. Stictosporince, Labbe, 1899. Spores biconical, with points slightly in- 

 curved and with papillae on the endospore. 



Genus 39. Stictospora, Leger, 1S93. Epimerite with globular head depressed 

 ventrally, and covered with ribs which project posteriorly as spikes. Spores 

 biconical. One species, S. provincialis, Leger, from the gut of Melolontha and 

 Rhizotrogus larva?. 



Group E. ActinocephalincB, Labbe, 1899. Epimerite always with appendages. 

 Spores regular, navicular or subnavicular, biconical or cylindrical. 



Genus 40. Schneideria, Leger, 1892. Sporont has but one chamber; epimerite 

 a thick plate bordered by rib-like thickenings. Spores somewhat thickened 

 and biconical. Two species, S. mucronata, Leger, from gut of larvae of Bibio 

 marci, and S. caudata from gut of larva of Sciara nitidicollis. 



Genus 41. Asterophora, Leger, 1892. The epimerite is a circular ridge with ribs 

 surrounding a prominent central papilla. The protomerite is as large or 

 larger than the deutomerite. Sporonts solitary; spores cylindrical with 

 conical extremities. Two species, A. mucronata, L., and A. elegans, L., from 

 the intestines of larvae of insects. 



Genus 42. Stephanophara, Leger, 1892. Epimerite large and in form of a convex 

 disk with a crown of digitiform processes. Spores cylindrical with conical 

 ends. One species, S. lucani, Stein, from gut of Dorcus sp. 



Genus 43. Bothriopsis, A. Schn., 1875. Epimerite in form of a large lens-shaped 

 knob with non-motile processes. Sporonts highly developed and very 

 motile. Spores biconical and thickened. One species, B. histrio, A. Schn., 

 1875, from the gut of Hydaticus sp. 



Genus 44. Coleorhynchus, Labbe, 1899. Sporont with sucker-like protomerite 

 extending over deutomerite. The convex septum projects into the proto- 

 merite. Cysts open by simple rupture; spores navicular. One species, 

 C. heros, A. Schn., from gut of Xepa cinerea. 



Genus 45. Legcria, Labbe, 1899. Protomerite enlarged and club-like, with 

 invading septum, as above. Spores with thick sporocysts and subnavicular 

 in form. One species, L. agilis, A. Schn., from gut of Colyrnbetes sp. 



Genus 46. Phialoides, Labbe, 1899. Complex epimerite consisting of a discoid 

 retractile cap surrounded by a circular ridge with collar-like membrane, with 

 ridges ending in triangular teeth. Sporonts solitary, massive ; spores biconical 

 and thickened. One species, P. ornata, Leger, from the gut of Hydrophilus 

 larvce. 



Genus 47. Geniorhynrhiis, A. Schn., 1875. Epimerite in the form of a disk which 

 bears fine pointed teeth and is carried on a long neck. Spores subnavicular. 

 One species, G. monnieri, A. Schn., from intestines of nymphs of libellulidae. 



Genus 48. Actinocephalus, Stein, 1S4S. Epimerite sessile or borne on neck-like 

 process, and is provided with hooks and spines. Spores biconical. Several 

 species from digestive tracts of beetles. 



Genus 49. Pijxinia, Hammerschmidt, 1838. Epimerite in the form of a cup with 

 rim surrounding a central spine. Many species (Fig. 73). 



Genus 50. Beloides, Labbe", 1899. Epimerite in the form of a disk or knob and 

 bearing about ten teeth in addition to a long spike. Spores navicular or oval. 

 Two species parasitic in the gut of species of Dermestes. 



Genus 51. Styloci/stis, Leger, 1899. Trophozoite non-septate; epimerite in the 

 form of a long spine which is usually curved. Sporonts solitary with biconical 

 spores. One species, S. precox, Leger, from the intestine of the larva of 

 Tanypus sp. 



Family 7. Acanthosporidcc, Leger, 1892. Sporonts always solitary; epimerite 

 simple or with appendages; cysts open by simple rupture; spores ornamented 

 with bristles at the poles or at the equator. Parasites of carnivorous insects. 



Genus 52. Corycella, Leger, 1892. Protomerite spherical and somewhat dilated.
