Anobiides. 

 Anobium (Litropeda) paniceum, Linn. 

 This is a small, dull-coloured, oval-shaped beetle, about one-fifth of 

 an inch in length, which is widely distributed throughout the world, and 

 drills the pin-holes in seasoned wood which are so commonly seen in old 

 furniture in Europe. Both the beetle and its larva tunnel in the wood. 

 The small insect which eats out elongate ramifying tunnels in books in the 

 library in India is this Anobium.
