Our recent experience in California, as well as that of Messrs. Co- 

 qnillett and Koebele last summer, would indicate that, while there are 

 few plants upon which the insect will not temporarily feed if it hap- 

 pen to fall upon them while in the first stage, yet the number of 

 plants upon which it can thrive and multiply is limited. The larva 

 will survive for weeks withoTit food and will wander about in search 

 of suitable food if it should find itself, for one cause or another, on 

 that which is unsuitable. It undoubtedly thrives best on Acacias, and 

 next to these we should place the Citrus fruits, the Quince, and the 

 Pomegranate, and we doubt if it could thrive upon many other trees. 

 The list of its food-plants, or rather of plants upon which it has been 

 found, is longer than is justified, not only because of its power of 

 endurance above noted, but because the young are easily carried 

 by wind or otherwise to plants more or less uncongenial and on which 

 they ultimately perish, while the adults are often dislodged from in- 

 fested Acacia or Citrus trees onto plants under or near them. 



Among the more valuable trees upon which it certainly cannot 

 thrive, and upon which it does not occur when they are grown at some 

 distance from infested Acacia or Citrus trees, are the following: Pines, 

 Cypress, Eucalyptus, Olive, Apricot, Peach, Pear, and Oleander. 



The plants upon which Mr. Coquillett found females with egg- 

 masses in limited numbers, and which were growing in situations so 

 remote from any infested Acacia or Citrus trees as to preclude the idea 

 that the adult insects had found their way to these plants from such 

 trees, were as follows: 



Pomegranate. 



Quince. 



Apple. 



Peach. 



Apricot. 



Fig. 



Walnut. 



Locust. 



Willow.
