feels may be found hanging on walls, pales, and 

 branches of trees, in the chryfalis ftate. 



Moths might likewife be procured more per- 

 fect, by collecling the caterpillars, and breed- 

 ing them in the fame manner as butterflies. As 

 the larvae or caterpillars cannot be preferved 

 dry, nor very well kept in fpirit, it would be 

 fatisfaftory if exact drawings could be made of 

 them while they are alive and perfect. It may 

 be neceftary to obferve, that in breeding thefe 

 kinds of infects, fome earth mould be put into 

 the boxes, as likewife fome rotten wood in the 

 corners, and fome mofs mould be put upon it, 

 which mould always be kept damp ; becaufe, 

 when the caterpillars change into the pupa, or 

 chryfalis ftate, fome go into the earth, and con- 

 tinue under ground for many months before 

 they come out into the moth ftate ; and fome 

 cover themfelves with a hard fhell, made up of 

 fmall pieces of rotten wood. Hence alfo, as 

 many go into the earth, valuable infects may 

 fometimes be found by digging after them a 

 foot deep, about the roots of trees, ftirubs, and 

 plants. 



IV- The fourth clafs of infects (neuroptera) 

 may be killed with fpirit of wine, oil of turpen- 

 tine, or by the fumes of fulphur. 



V. Thofe of the next clafs (hymenoptera) 

 may be killed in the fame manner. A pin may 

 be run through one of their wing-fhells and 

 body, as reprefented in pi. 1, fig. 5.
