355] STUDIES ON GREGARINES— WATSON 145 



Ellis removed this species from the genus in which it was first 

 placed, and included it among the members of the genus Anthorhynchus. 

 This genus and Asterophora are differentiated by the character of the 

 epimerite and spores. In our present discussion, the latter factor may 

 be omitted since the spores are not known. The epimerite of Anthor- 

 hynchus is a large canaliculated button ; that of the Asterophora con- 

 sists of a circular cushion with a central knob and with a fluted, crenu- 

 late periphery. Crawley's species, therefore, coincides with the latter 

 description and should be returned to that genus. 



BELOIDES FIRMUS (Leger) Labbe 



[Figures 116, 214] 



1892 Xiphorhynchus firmus Leger 1892 :137-9 



1899 Beloides firmus Labbe 1899 :26-7 



Beloides: Sporonts solitary, elongate. The adults 80/x in length, 

 Protomerite conical, dilated in center, constriction at septum. Deuto- 

 merite widest at shoulder, tapering to a sharp point. Ratio length pro- 

 tomerite : total length : : 1 :3.8 ; width protomerite : width deutomerite 

 : : 1 : 1.2. Nucleus elongate ellipsoidal, with several karyosomes. Epi- 

 merite a stalked globose papilla with 12 large lateral curved spines and 

 a long rigid central style (SO/x long in adults). 



Cysts spherical, 180 - 200/x in diameter, dehiscence by simple rup- 

 ture, biconical, 14.5 by 6/x. 



Taken at Poitiers, France. Host: Dermestes lardarius L., larva. 

 Habitat : Intestine. 



BELOIDES TENUIS (Leger) Labbe 



[Figure 117] 



1892 Xiphorhynchus tenuis Leger 1892 :139 



1899 Beloides tenuis Labbe 1899 :26-7 



Beloides: Sporonts solitary, elongate. Epimerite a stalked globu- 

 lar papilla, with 12 stiff lateral curved spines surmounted by a long 

 slender sinuous style. 



Cysts spherical, spores biconical, pointed. 



Taken at Poitiers, France. Host: Dermestes undulatus Brahm, 

 larva. Habitat: Intestine. 



Labbe changed the genus name of this and the foregoing species be- 

 cause of priority.
