Inhabits moist places ; rare near London, more 

 abundant in Norfolk and Suffolk. 



This little insect is seldom met with from the cir- 

 cumstance of its inhabiting the muddy banks of 

 ponds and covering itself over with sand or dirt, 

 most probably to evade the numerous Carabidcs 

 which feed on other insects and are common in the 

 above places. 



They are found during the spring months, and 

 possibly amongst sedges (at the roots) during the 

 winter,
