THE CIGAR CASE-BEARER. oD 
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 Ilustrated Descriptive Cata- 
logue of Some of the More Injurious and Beneficial Insects of New 
York State.¢ 
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.” 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 shghtly 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 larvee 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 early part 
of June, so badly infested by the insect that literally every leaf had 
been’ devoured. 
Mr. Rh. 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 
“Bull. 39, N. Y. State Mus., 1900.
