scattered through the woods, where they feed on the wild grape. 
In midsummer they are also often abundant on clover. 
Norr.—Adult specimens of Colaspis tristis were collected by sweep- 
ing the foliage of the strawberry in June, in such numbers that it 
is very probable that this species will be found to have similar 
habits and history to those of C. brunnea. They were feeding on the 
leaves of the strawberry in August.

LITERATURE. 
The first, of the above-named forms, described originally by Olivier*, 
was re-described by Say under the name of Colaspis striata, in 1824+, 
and a form now reckoned a variety of this species was described 
by Leconte in 1859, under the name of Paria opacicollist. 
Paria sexnotata, very doubtfully distinguishable from the species 
just mentioned, has hkewise been frequently described, first by Say 
in 1824+, and again by the same author under the name of 4-notata, 
by Leconte as 4-guttata, and by Dejean as gilvipes. 
As an injurious insect, this was first mentioned in the Report of 
the Ontario Entomological Society for 1873. In the brief account 
of it there given, the adult is said to have been extremely injurious in 
Canada, completely riddling the strawberry leaves in fields near Dela- 
ware. It was next mentioned in this connection by Prof. A. J. Cook, of 
Lansing, Michigan, who, in a paper read before the Ingham Horti- 
cultural Society in i880, and published in the Report of the Horti- 
cultural Society of Michigan, for that year, reported this species as 
a root-worm of the strawberry, occurring in destructive numbers 
near Lansing, Michigan. A review by Prof. Riley of Prof. Cook’s 
paper, with some additional details, appeared in the third volume 
of the American Entomologist, in 1880; and a revision of the origi- 
nal article of Prof. Cook was published in the report of the State 
Board of Agriculture of Michigan, for the year ending August 31st, 
1880. Another account of the species, with some additional notes 
upon its habits, was given by myself in the Transactions of the 
Illinois State Horticultural Society for 1882, and again in the fol- 
lowing year in a paper on ‘‘Insects Affecting the Strawberry,” pub- 
lished in the Transactions of the Mississippi Valley Horticultural 
Society for 1883.
