 which attack peas and beans. 



The oil-bottles and blister-beetles are a curious group, 

 since in their young stages many of them are parasitic 

 upon other insects, while when adults they contain a pecu-

 article of commerce under the name of Spanish flies.

The snout beetles (Rhynchophora) or true weevils are all 

 injurious, since as larvae and adults they feed upon vegeta-

 Certain ones burrow between the bark and solid woods 

 of trees, excavating curious mines, while others bore into 

 the solid wood.
