Pbs. — The Pselaphi are obtained by seeking at the roots of grass, in 

 sand-pits, Sec. but being so exceedingly minute they easily escape the 

 eye of the entomologist unless he looks very close to the ground; 

 the usual practice is either to sit or lie down, and by this means 

 many highly interesting and rare insects may be taken whilst the 

 entomologist rests from a more laborious mode of collecting,
