Chermes pinicorticis Fitch is always more or less injurious to white 

 pines in Washington Park, Albany, but this year it has been excep- 

 tionally abundant, not only gi^-ing considerable portions of the trunks 

 a whitewashed ax)pearance, but literally plastering the under surface 

 of many limbs. A number of these pines, as a consequence, have a 

 thin foliao-e and are sicklv. 



Mr. Hopkins congratulated the author on the large number of spe- 

 cies recorded, but he doubted that the tent caterpillar had so changed 

 its habits as to attack pine. He was of the opinion that the occurrence 

 of this insect upon pine was merely accidental. 



Mr. Ashmead said that he also was skeptical about the occurrence 

 of the tent caterpillar on pine, and he advised Mr. Felt to ^vithhold 

 that statement from x3ublication until further investigation could be 

 made. 



Mr. Cockerell mentioned that in Xew Mexico the larv?e of CJisio- 

 campa frag ills sometimes crawled up the pine trees and pujoated 

 among the needles, but he did not find any proof that they ate the 

 leaves. With regard to the insect called Fseudococcus aceris in the 

 Eastern States, it could not be placed in Westwood's genus Pseudococ- 

 cuSj but belonged to Phenacoccus. The species was almost certainly 

 not the European P. aceris, but was probably American, and without 

 a name.

The white fly {Aleurodes citri) reached its maximum of destructive- 

 ness last year, and called forth mucli apprehension both within the 

 bounds of its present distribution and outside of them. About 75 jjer
