Mr, Green tells us that this species is not uncommon in the district 

 of Pundaloya; in the larval stage, at least, it is to be found under 

 stones, or under moss on rocks, or under loose bark on trees. It is 

 extremely active, and the adult insect flies by night, and may be taken 

 at light.
