Phytosus. Paulian (1941) reported it absent in Aleochara , A theta 
and Cyphea. 
Osmeterial Glands 
Through the transparent integuments of the larvae of O. ovi- 
formis there are visible on each side of the area of the osmeterium 
a pair of tubular coiled structures which appear to be connected to 
the osmeterium by convoluted material. These would seem to be 
glands so it may be reasonable to call them osmeterial glands. If the 
osmeterium gives off an offensive odor these could be its source.
