extremely slow. A number of animals showed no movement whatever 

 and some of these held the scalloped outhne without change. 

 Dimensions: Length 225-700 microns. _ 



Host- Harpalus caliqinosus. The gregarines were present m the 

 intestine of the one beetle examined in hundreds, and while no associ- 

 ations were seen, there was a very marked tendency for them to be 

 lying massed closely together. 

 Locality: Wyncote, Pa. 



mirmocystis ovalis sp. u. PL I, Ags- 5-6. 



Evimerite: Usuallv elliptical in outhne, with the longer axis trans- 

 verse, but frequently considerably flattened down. Wall with double 

 contour. Contents hyaline. 



Protomerite: Hemispherical. 



Deutomerite: Cylindrical to oval, but more usually the latter. 

 Always terminating bluntly. _ 



Epicyte: Thin over the anterior part of the protomerite; elsewhere 

 thick. Longitudinal striations not seen. 



Sarcocyte: ?. . , , i i? ; 



Entocyte: Dark brown in the larger individuals, and of approxi- 

 mately the same density in both protomerite and deutomerite. The 

 anterior third of the protomerite is usually, but not always, free from 



granules. 



Nucleus: Not seen. 



Dmensions; Greatest length 70 microns. ■ , ,. 



Host- The larva of a beetle doubtfully identified as belonging to the 

 Cucuiidffi The gregarines occurred sparingly, ten or twelve being the 

 greatest number lound in any one host. About half the insects exam- 

 ined w^ere parasitized. 

 T Euspora lucani sp- n.^ PI. HI, fig. 38. 



lZomt%e:'^m^\\, compressed from before backward. Separated 

 from the deutomerite by a deep constriction. 



Deutomerite: Cyhndrical; sometimes narrower m the middle. 

 Epicyte: Thick.

 Entocyte: ?.
