In the intestine of the beetle, TriboUum ferrugineum F., I have 

 found four polycystic! gregarines, of which one is referable to the 

 already known species Gregarina cuneata F. STEIN, while the remain- 

 ing three are forms apparently not yet described. The host beetles 

 were collected in the Province of Izu in the early part of October 

 last year.
