PYXINIA FRENZELI Laveran and MesnH 



[Figure 89] 



1900 Pyxinia Frenzeli Laveran and Mesnil 1900 :554-7 



Pyxinia : Sporonts solitary, obese. Lengtli 200ft. IVEaximum length 

 of cephalonts 150/i,. Maximum width 40fi. Cephalonts only illustrated." 

 Ratio length protomerite : total length : : 1 : 4 ; width protomerite : 

 width deutomerite ::1 : 2. Protomerite (of cephalonts) cylindrical to 

 subglobose, constricted at septum. Deutomerite subglobose, nearly as 

 wide as long. Epimerite in two parts, a slender cylindrical base equal 

 in length to protomerite, and superimposed upon same, and a short, 

 sharp, apical style equal in length to the cylinder. Nucleus spherical, 

 containing a large karyosome. 



Cysts not seen ; spores ovoidal, 14 by 6/i. 



Taken at Paris. Hosts: Attagenus pellio (Dermestes sp.). Habi- 

 tat : Intestine. 



PYXINIA MOBUSZI Leger and Duboscq 



[Figures 97, 98] 



1900 Pyxinia Mobuszi Leger and Duboscq 1900 :1566 



1902 Pyxinia Mobuszi Leger and Duboscq 1902 :409-18 



Pyxinia : Sporonts solitary. Length 100 to I'Mi/x. Width not given. 

 Ratio length protomerite : total length : : 1 : 5 to 1 : 6. Width protome- 

 rite : width deutomerite : : 1 : 1. Protomerite hemispherical, lower 

 margin straight, projecting beyond deutomerite at septum, Deutome- 

 rite regularly cylindrical, ending in a blunt point or in a well rounded 

 extremity. Epimerite persistent, a long slender sinuous style attached 

 to base of the epithelial cell, i. e., to mesothelial wall, of the host, extend- 

 ing through this cell, longitudinally, to lumen, the cephalont body re- 

 maining in lumen, beyond cilia. Epimerite as long or longer than the 

 whole cephalont itself. Endocyte containing paramylin granules and 

 small yellow refractile bodies. Nucleus spherical, with one karyosome 

 and several chromatic granules. 



Cysts spherical, 60 to lOfi in diameter. Spores elongate, barrel 

 shaped, 6.5 by 7/a long. 



Taken at Grenoble (?), France. Host: Anthrenus verbasci Olivier, 

 larv. (A. verbasci L.) Habitat: Intestine.
