THE OUESTS OF ANTS AND TRP.MITKS, 



205 



being nnattackable, and that finally the ant^^, taking pleasure in licking 

 it, would elevate it to the rank of a true guest. But it is not as simple 

 as it appears. In my observation-nests I have had a number of 

 Hetaerim for more than five years, and I have come to the conclusion 

 that it would be better for this species to be merely tolerated. It is in 

 truth licked by the ants, but this is not to its advantage, as the ants 

 do not feed it. It is often in great danger. Formica mniiuinea and 

 pratensis play with it for a quarter of an hour at a time, like a cat plays 

 with a mouse, trying to get hold of its Jaws, so it is often hurt. Once 

 a Hetaerius was so badly used by a Formica satv/uinca that it Avas half 

 killed and nearly devoured. Whilst licking the wounded beetle the 

 ant's greed had been awakened. 



So as to give before we finish a systematic review of the classes, 

 orders and families of the guests of ants and termites, I have added to 

 this treatise a table taken from my Kritischen Verzeichniss der myrmeko- 

 pliilen und termitophileii Arthropodcn. (Where the Termitophila are not 

 mentioned, the family possess only Myrmecophila.)
