GREGARINA ACUTA (Leger) Labbe 



[Figure 217] 



1892 Clepsidrina acuta Leger 1892 :121-2 



1899 Gregarina acuta Labbe 1899 :11 



Gregarina: Sporonts biassociative. Protomerite short, cylindrical, 

 rounded in front. Deutomerite cylindrical, rounded behind. Nucleus 

 spherical, with one karyosome. Epimerite a sharp point. 



Cyst and spores unknown. 



Taken at Poitou, France. Host: Trox perlatus Scriba. Habitat: 

 Litestine. 



GREGARINA STEINI Bemdt

 1902 Gregarina steini Bemdt 1902 :408-13 



Gregarina: Sporonts biassociative, 42 to 150/i, in length, width 16 to. 

 30/A. Protomerite hemispherical. Constriction at septum. Deutomerite 

 widest at shoulder, tapering to a more or less slender but well rounded 

 posterior extremity. Epimerite a simple globular papilla. 



Cysts ovoidal, 70 to lOO/x by 85 to 160/x. Cysts smaller than those of 

 G. cuneata or G. polymorpha. 



Taken in Berlin, Germany. Host : Tenehrio molitor L. larva. Hab- 

 itat : Intestine. 



The work on this species needs confirmation before it can be ac- 

 cepted absolutely. Leger and Duboscq (1904:351-60) described the greg- 

 arines of the larva of this beetle but made no mention of this species. No 

 one of the previous workers on the same beetle has mentioned it. Not 

 knowing how polymorphic G. polymorpha may be, the present writer 

 does not wish to comment on this species.
