Annual Report.] 178 [May i, 
Harris Collection has been several times re-examined, and at 
last a plan has been devised by which the trays can be made 
insect tight. This will save the Society the great expense of 
furnishing new boxes, and will be just as safe. A sample 
of one of these trays is upon the table and may be examined 
by the members of the Society. The work upon the type 
collection has already been sufficiently described in the gen- 
eral report. 
The larger collections received during the year are as fol- 
lows: from Mr. James Boll, 150 specimens of European Lep- 
idoptera, and 300 of Coleoptera, notable for their fine condi- 
tion, and the care exhibited in their preparation; and in ad- 
dition to previous gifts of valuable material the bequest of 
his entire cabinet, consisting chiefly of North American in- 
sects, coupled with a sum of money ‘for its preservation by 
our late associate, Mr. Wm. H. Dale. 
Contributions of exotic specimens in small lots are chroni- 
cled from Messrs. Samuel Wells, W. H. Holden, and Benj. P. 
Mann, besides a fine living specimen of Mygale Hentzii Gir., 
with its “trap-door” nest, from Miss Nellie Stone of Califor- 
nia. New England specimens, living and otherwise, have 
been presented by P.S. Sprague, Dr. G. F. Waters, I. G. Shute, 
F. A. Sherriff, A. B. Warren, F’. A. Clapp, Luther Hills, Henry 
L. Moody, Miss C. Guild, and Mrs. McLean. Boreus bruma- 
lis Fitch, was found in great numbers by Mr. Moody, in Mal- 
den, upon the snow, Dec. 17th, 1871, and over fifty specimens 
of both sexes were presented to the Society by him. Subse- 
quently, B. nivoriundus Fitch, the only other species known in 
this country, and new to the Society’s collection, was obtained 
in smaller numbers and added to the cabinet by the Commit- 
tee on Jan. 21st, 1872. Many of the specimens presented by 
Mr. F. A. Clapp are chenilles sifjiées, carefully prepared by 
him in the manner recently suggested by European ento- 
mologists, by emptying the larval skin and inflating it ina 
current of heated air.
