383] STUDIES ON GREGARINES WATSON 173 



Schmidt'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 1'une des varietes que nous aliens 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. 



GEEGARINA AMARAE Frantzius 



1838 Clepsidrina ovata Hammerschmidt 1838 :356 



1848 Gregarina amarae Frantzius 1848:195 



1851 Gregarina Amarae Diesing 1851:12 



1863 Gregarina Amarae Lankester 1863:94 



1899 Gregarina amarae Labbe 1899:36 



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 cuprea, in intestinus tenuibus (Hamm.)." 



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

 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.
