THE CANADIAN ENTOMOLOGIST. 231 



Very severe injury had been done during the present year by the insect 

 in the pear orchards of the Hudson River Valley. 



Mr. Schwarz said that four species had been confused as Psylla pyri 

 by various European authors ; that Dr. Franz Loew had, in the Verh. z. 

 b. Ges. Wien, written exhaustively on the subject, and that Schmidberg- 

 er's pyri is identical with pyrisuga, Foerster, which does not occur in 

 North America. He had observed pyricola in Michigan, where it is not 

 common and where, late in the fall, it assumed that intense coloration 

 which indicates hibernation in the imago state. 



Mr. Lintner spoke further 



ON THE EYE-SPOTTED BUD-MOTH {TlUetOCera OCClland) IN WESTERN 



NEW YORK. 



This insect had been very destructive in the orchards of the western 

 part of the State — many of the orchardists representing it as having 

 caused them more harm in their apple orchards than all other insect pests 

 combined. The caterpillar fed upon the unopened buds, on the blossoms, 

 on the young leaves as they first put forth, webbing them together, on the 

 advanced foliage, and it was also reported as boring into the young twigs. 

 Its habit of concealment, after its operations disclosed its presence, made 

 it almost impossible to reach by the usual application of the arsenites. 

 From the severe injury that it was occasioning, it was very desirable that 

 some method of destroying it should be discovered and recommended to 

 our fruit growers. He had believed that eggs were deposited in the 

 month of April by the parent moths, from some imperfect and denuded 

 specimens that had been captured fluttering about the fruit trees at this 

 time, and which seemed to be that species ; but Prof. Fernald and others 

 had stated that the insect hibernated as a half-grown larva under a silken 

 tent spun upon the fallen leaves. Some of the larvae which Mr. Lintner 

 had hatched from the eggs in June, had attained such size in early July 

 when they died, that they should certainly have attained full maturity 

 during the early autumn. He also exhibited specimens of the very 

 remarkable, extremely flattened and disc-like egg, which he thought could 

 not be the same with that which Prof. Fernald had described in Bulletin 

 No. 12 of the Hatch Experiment Station for April, 1891. If the egg is 

 deposited in the early spring, it could be killed by a kerosene emulsion ; 

 if the larvae hibernate in the fallen leaves, they could be kept from 

 ascending the tree, or destroyed by collecting and burning the leaves.
