 vation is found feeding. As many insects as 

 possible should be raised under observation. 



2. In carrying on the above work 

 instances where the caterpillar has been 

 attacked by parasites are sure to come under 

 observation. Careful note should be made 

 of these, and specimens of the parasites should 

 be reared, drawn and described.

 from time to time, of the insects found upon 

 particular crops, keeping specimens of the 

 insects, drawings or descriptions, with notes 

 of the parts of the plants attacked and of the 

 injuries caused. Thus lists may be made of 

 insects found upon corn, sweet potatos, 

 cacao, limes, oy sugar-cane ; these lists, may
