383] STUDIES ON GREG ARINES— WATSON 173 



sclimidt's original determination, the three species which Stein had dif- 

 ferentiated, and added another variety. He described 1) Clepsidrina 

 polymorpha var. cuneata, 2) C. polymorpha typica, 3) C. mimosa, and 4) 

 disposes of Stylorhynchus ovalis Stein as 



" simplement le cephalin de Tune des varietes que nous allons decrire." 



Of these forms, the first has been designated Gregarina cuneata 

 Stein; the second remains Gregarina polymorpha; the third has been 

 dropped as an authentic species for it is obviously immature and prob- 

 ably from its shape a young individual of G. cuneata; the fourth is now 

 Steinina ovalis (Stein) Leger and Duboscq. 



Berndt separated the species G. polymorpha from G. cuneata, de- 

 scribing each in detail, Leger and Duboscq corroborated his work and 

 created the genus Steinina for the species previously known as Stylo- 

 rhynchus ovalis Stein. Ishii found the species in Japan, from one of 

 the Tenebrionidae. No description of adults is given. 



GREGARINA AMARAE Frantzius 



1838 Clepsidrina ovata 



1848 Gregarina amarae 



1851 Gregarina Amarae 



1863 Gregarina Amarae 



1899 Gregarina amarae 



This parasite has not been found since the original discovery of 

 Hammerschmidt. Frantzius mentioned it by name only; Diesing gave 

 this description : 



"Gregarina Amarae Frantzius. 



Proboscis Receptaculum ovatum breve. Corpus subglobosum. Longit. 



9/40 ' ' ', crassit 



Clepsidrina ovata Hamm. (Individua bina postice juncta)". . Habitac- 



ulum Amara ciiprea, in intestinus tenuibus (Hamm.)-" 



Labbe says that the host is probably the beetle known now as Foecir- 

 lus cupreus (L.). 



That this species is a member of the genus Gregarina is attested by 

 Diesing 's words "Individua bina postice juncta" which indicates the 

 biassociative nature of the sporonts. No drawing accompanies any 

 available mention of the species.
