THE CIGAR CASE-BEARER. 35 



A brief account of the life history of the insect is given by Dr. 

 E. P. Felt in the Country Gentleman for November, 1901, and it is 

 referred to by the same writer in his Illustrated Descriptive Cata- 

 logue of Some of the More Injurious and Beneficial Insects of New 

 York Stated 



Prof. S. A. Forbes in 1900 gave a brief note on a similar insect 

 feeding on sugar beet. At the time this was supposed to be C. fletch- 

 erella Fernald, having very similar habits and appearance. Mr. 

 August Busck, of this Bureau, however, has recently examined speci- 

 mens sent by Professor Forbes and finds that they belong to a differ- 

 ent species. 



In 1902 it was included in Banks's Principal Insects Liable to be 

 Distributed on Nursery Stock. 5 It is here recorded feeding upon 

 pear and quince. 



Specimens were received by Doctor Fletcher from Victoria, British 

 Columbia, in 1905, and were sent by him to this Bureau for deter- 

 mination. The moths, which were examined by Mr. Busck, were 

 found to be slightly smaller than those from New York or east- 

 ern Canada. Recently Mr. Busck has been kind enough to reexamine 

 the specimens, and from a comparison of later collected material in 

 the United States National Museum collection considers those from 

 Victoria to be identical. The larvae of the moths mentioned above 

 were found feeding on hawthorn. The difference in size is probably 

 due to local conditions and to the different food plant. 



In a letter dated February 16, 1909, to this Bureau, Prof. R. H. 

 Pettit, of the Michigan Agricultural College, states that he received 

 specimens of the cigar case-bearer from Port Hope, Mich., where in 

 1908 it was reported as being quite a serious pest. 



During the summer of 1908 the writer had the opportunity of 

 studying the cigar case-bearer at North East, Pa. A small orchard 

 of 40 or 50 trees belonging to Mr. A. L. Short was, in the earfy part 

 of June, so badly infested by the insect that literally every leaf had 

 been devoured. 



Mr. R. W. Braucher, of this Bureau, during the summer of 1908 

 observed the insect at Douglas, Mich., where it was found more or 

 less frequently in different orchards. 



DISTRIBUTION. 



The cigar case-bearer is evidently a native insect, feeding originally 

 on crab apples and hawthorn. Although at present recorded only 

 from scattered sections of the country, it is not improbable that it 

 has a rather general distribution. In Canada, Fletcher reports it 



a Bull. 39, N. Y. State Mus., 1900.
