 disputable facts were added to our stores of Natural History. 



In addition to the instructions thus given, I should be dis- 

 posed to add a further suggestion. No provision is here made 

 for preserving the insect for dissection. So, if several specimens 

 of a larva could be found, I should suggest that a larva, pupa,
