impossible to make them move again. In many cases both legs 

 and feelers fit in grooves, and the entire insect appears to be des-

 will show the range of their habits.

 other ways ; and our soldiers can tell many a story of ship-biscuits 

 enlivened by the presence of their larvre. In fact the writer has 

 seen biscuits thus infested that contained as much animal as 

 vegetable matter. 



The Cigarette-beetle (Lctsiodcrma serricome Fab.), is a 

 great lover of the weed in all its forms, and neither chewing nor
