342 CLASS VIII. 
ash-grey insect, that resembles a small moth, is found on walls in moist 
situations ; it can turn itself about very cleverly, and springs more than 
it flies. The larva is dirty yellow, with a black-brown head and awl-shaped 
horny tail, and lives in decaying vegetable matter. Boucué Naturgesch.
