Discussion: Forcellinia wasmanni (Moniez) was described from ants' 

 nests and is European in distribution. All stages of the mite are to be 

 found in the nests. According to information from Michael 1903 the 

 mites often appear to increase in great numbers in nests and the hypopi 

 adhere to the ants in such quantities that they cause the death of the 

 ant. Fifty to a thousand mites may be found attached to one ant. They

are most numerous on the head, abdomen, and legs; only a few are 

 found on the thorax. The hypopi are supposed to attach themselves 

 in the direction of the long axis of the segment they are on, their an- 

 terior end being directed toward the point of the segment. 



Scatoglyphiis polytrematus Berlese was found in fowl excrement 

 with other acarids.
