A careful and systematic inquiry, into the food-plants of the larvae of 

 different genera of butterflies and moths is desirable, and it will probably 

 be found that each genera, although able to survive on many different 

 kinds of plants, is identified with certain natural orders, e.g., Pieris with 

 Cruciferae, Argynnis with Violaceas, Vanessa with Urticacas, &c., or with 

 orders which stand nearest to them. The key of this line of investigation 

 will probably be found in the relation which the mature insects bear to 

 ihe colour, shape, and other characters of the flowers, &c., of the plants 

 and trees on which their larvae feed, as they are generally found in the 

 neighbourhood of such plants. Here, again, is another interesting sub- 

 ject for investigation — the relation of mature insects to flowers and their 

 fertilizations — which remains to be worked out in detail on the lines laid 

 down by Darwin, Lubbock, and other naturalists.
