 from which drawings may be taken for illustrating this report, 

 and which are thereafter to be deposited in the Entomological 

 department of the Museum of the Society. 



It has been common in treatises upon economical entomology,

 viduals in our country possess. A person who meets with a 

 worm, say, mining a cavity in the leaves of the apple tree, and 

 consuming their parenchyma, -knows not whether that worm is the 

 larva of a Coleopterous, a Lepidopterous, or some other Order of 

 insects, and consequently is at a loss in what part of a work upon
