INSECTS INJURIOUS TO THE HEMLOCK. 241 
\ 
a common beetle. A few other borers are mentioned below which we 
have found the past summer in dead hemlock trees. 
2. A large longicorn borer. 
Order COLEOPTERA; family CERAMBYCID®. 
Mining under and loosening the bark of failen hemlock logs near the Glen House, 
White Mountains, N. H., a large longicorn borer with the general appearance of Mono- 
hammus, but belonging to a different genus. Lengthof the different specimens from 
anonyeoon, 
. 3. A short, thick longicorn borer. 
Order COLEOPTERA; family CERAMBYCID. 
Found under the bark of dead hemlocks at Bath, Me., July 30, a short, thick un- 
known longicorn borer. 
4. A Buprestid borer. 
Order COLEOPTERA; family CERAMBYCID%. 
Found under the bark of dead hemlocks at Bath, Me., July 30, a Buprestid larva of 
different sizes, perhaps a species of Dicerca. 
5. THE WHITE PINE WEEVIL. 
Pissodes strobi Peck. 
This weevil and its cells were found in hemlocks among a number of 
small standing dead spruces, which had, like them, been killed by the 
attacks of longicorn borers, and by the following species of bark-borer: 
6. THE LEAST SPRUCE BARK-BORER. 
Crypturgus atomus Leconte. 
This minute bark-borer was observed in considerable numbers in 
standing dead hemlocks at Bath, Me., July 30. 
7. THE HEMLOCK BARK-BORER. 
Hadrobregmus foveatus (Kirby). 
_ Order COLEOPTERA; family PTINID®. 
The bark of hemlock trees and of hemlock logs, as well as the sep- 
arated bark piled up by the roadside near the Glen House, in the White 
Mountains, last summer, was found to be perforated in all directions 
by this beetle, which has been obligingly identified by Dr. G. H. Horn, 
of Philadelphia. Not only the bark of dead trees, but that of healthy 
jarge trees had harbored great numbers of these beetles. They, how- 
ever, had disappeared from the holes at the date (July 22) I was at 
the White Mountains, and but a single dead specimen was found. Simi- 
lar mines were found in a hemlock at Brunswick, Me. 
8. THE BROWN PRIONUS BEETLE. 
Orthosoma brunneum (Forster. ) 
» Order CoLeoPpTERa; family CERAMBYCID. 
Mr. F. G. Schaupp writes me as follows concerning this beetle, which 
is not harmful to the tree, attacking it usually when in the last stages
