*“P‘ t- Bsel. Herbstii. (PI. 4. jig. 15.) magnified: the line beneath shows 
the natural size. 
^habits banks and river sides. 
t'ns — The Pselaphi are obtained by seeking at the roots of grass, in 
sand-pits, Sec. hut being so exceedingly minute they easily escape the 
c.fe of the entomologist unless he iooks very close to the ground ; 
the usual practice is either to sit or lie down, and by this means 
uiany highly interesting and rare bisects may lie taken whilst the 
entomologist rests from a more laborious mode of collecting.
