Asterophora cratoparis sp. n.5 pi. ii, fig. 2S. 



Epimerite: Small; consists of a number of ribs projecting from a 

 central knob. 



Protomerite: Nearly reniform, but with a conical projection in front, 

 upon which rests the epimerite. Separated from the deutomerite by a 

 sharp constriction. 



Deutomerite: Lanceolate; terminating bluntly. 



Epicyte: Thick. 



Sar oocyte: ?. 



Entocyte: ?. 



Nucleus: Not small; spherical, with a spherical karyosome. 



Dimensions: Length 540 microns. 



Host: Cratoparis lunatus, a beetle of the family Cm'culionidse. Eight 

 gregarines, all attached to the wall of the host's intestine, were present 

 in the one individual examined. 



Locality: Swarthmore, Pa. 



Stephanophora locustaecarolinae Leidy. 



Gregarina locustcecarolince Leidy (1853), p. 239, PL 11, figs. 35-38. 

 Provisionally placed in the genus Stephanophora on account of the 

 character of the epimerite. I have not yet encountered the species. 



Botliriopsis histrio Aime Schn. PI. II, figs. 15-18. 



Bothriopsis histrio Schneider (1875), p. 596, PI. 21, figs. 8-13. 

 Bothriopsis histrio Leger (1892), p. 136, PI. 13, figs. 1-3. 



This gregarine was described by Aime Schneider in 1875. The diag- 

 nosis then given is as follows : Epimerite wanting. Protomerite form- 

 ing a large rounded mass, of which the anterior part may be either very 

 convex or quite concave. Deutomerite oval. Septum projecting for- 

 ward in such a fashion that it resembles the finger of a glove. Nucleus 

 elliptical in outline, with several karyosomes. Epicyte with double 

 contour, sarcocyte wanting and entocyte very finely granular. Animal 

 highly polymorphic and movements very rapid. 



Hosts: Hydaticus cinereus (larva), Colymbetes fuscus and Acilius 

 sulcatus. 



Leger adds the information that the epimerite consists of a number of 

 long filaments. 



I find what is apparently the same gregarine in the larva of Dytiscus 

 sp., but four or five imagines were opened in vain. My observations, 

 however, differ somewhat from Schneider's, although they do not 

 appear to warrant creating a new species. 



Fig. 15 shows the protomerite of this gregarine. As stated by Schnei-
