smaller leaves are dead, and the others are almost entire skeletonized 

 by the insect. We have no definite data as to just how much damage 

 the insect did in 1894. Apparently it now ranks next to the bud- 

 moth (Bulletin 50) in destructiveness ; and the two insects are often 

 seen at work on the same branches. 



Thus this new case bearer affords an additional emphasis to the 

 fact that eternal vigilance on the part of the fruit grower is now the 

 price which must be paid for the finest and best fruit. 



Its Past History and Distribution. 



Doubtless this case bearer has been present in limited numbers in 

 New York orchards for many years ; and it may have been pre- 

 viously noticed by some fruit growers, but it was not until 1888 

 that public attention was called to it, by Mr. P. Barry of Eoches- 

 ter, IST. Y. He found it boring holes in newly-set pear fruits, and 

 specimens were sent to Dr. Lintner ; these specimens furnished the 

 text for the first published account of the insect, by Dr. Lintner in 

 1890. In 1892 Dr. Lintner received some apples from Oswego 

 N. Y., which had apparently been bored by this case bearer. 



Nothing further seems to have been heard of the insect in our 

 State until last year (1894.) Then specimens began to come into 

 the insectary from western New York as early as February, and 

 continued coming in increased numbers during the months of May 

 and June. Specimens were received from the following localities : 

 Kochester, West Brighton, Moreton Farm, North Rose, Albion, 

 Newark, Sodus and South Byron ; this winter we have also received 

 specimens from North Parma, and have seen the insect here in 

 Ithaca. The specimens sent in indicated that it was present in 

 alarming numbers in nearly every case. Doubtless it will be found 

 generally distributed throughout the State, and it probably also 

 occurs in neighboring States. 



The insect is also very numerous in Canada. It first attracted 

 attention there in 1889 at Charlottetown, Prince Edward's Island. 

 In 1891, it appeared in alarming numbers . at Adolphustown, 

 Ontario ; and a few were also found at Port Williams, Nova Scotia. 

 Last year it did very serious damage in several localities in Ontario ; 

 specimens were also sent to the insectary from Lakeville, Nova 

 Scotia. 



Thus, this case bearer has so far been recorded only from New 

 York and Canada, and has appeared in alarming numbers only in
