In one case I have found a free sporont which was apparently 

 without protomerite. It was slightly narrower at one end of the 

 body. Probably I had only a detached satellite before me. 



Infection not heavy, nor common. 



This form resembles in some points Grcgarina Steini which was 

 described by BERNDT 1;> from the intestine of Tenebrio nwlitor, but differs 

 from this in the much smaller protomerite, in the thicker deutomerite, 

 and in the frequent absence of protomerite in the satellite. 



4. Steinina obconica sp. nov. (Fig. 4). 

 In trophic stages always solitary. 



Epimerite not deciduous, somewhat conical in shape, small and 

 short, having an average length of only 6 fi. On several occasions
