The species llypocyptus live mostly on moist or half-iiioist 

 ground beneath plant-surface; and are therefore often found in al- 

 luvium, but also at rotting plant-parts, in plant-dung and in gnav.- 

 crumblings under bark. In North- and Middle-Europe £ species are 

 found, of which 4 or 5 in Denmark.
