The Food Relations of the Carabidce and Coccinellid<e.

Genus Beachynus. 
A single specimen of Brachynus fumans , caught in Central 
Illinois, in May, had taken only liquid animal food. 
Genus Galekita. 
Seventeen specimens of G-alerita farms , four collected in vari- 
ous situations, and thirteen in the orchard in Tazewell County, 
had made a much more varied record. All of the group first 
mentioned had eaten insects, which amounted to eighty-eight per 
cent, of their food, nearly all caterpillars of undetermined species. 
The remaining twelve per cent, consisted of vegetable food eaten 
by two of the specimens, and was apparently derived chiefly 
from the seeds of grass. A larger ratio of animal food is 
noticed in the thirteen taken where canker-worms abounded. 
Here vegetation amounted to only six per cent., all of exogenous 
origin, as shown by the branching bundles of spiral cells in the 
vegetable fragments noticed, while the animal food amounted to 
ninety-four per cent. Insects stand at eighty-five per cent., seven 
per cent, being Diptera, one per cent, unrecognizable insect larvae, 
and the whole of the remainder caterpillars. The last were 
nearly all easily determined as canker-worms, which amounted to 
a little over half the food. Seven individuals of the thirteen had 
eaten these worms. Five per cent, of the food (taken by three of 
the specimens) consisted of spiders, and four per cent, (taken by 
a single specimen) was animal food, not otherwise determinable. 
The remains of a caterpillar in the stomach of a single beetle 
were clearly distinguished as those of a noctuid larva (cutworm). 
If from the ratios of animal food taken by the examples from 
the orchard we subtract the ratio of canker-worms (fifty-two per 
cent.) the remainder is just seven times the ratio of vegetation eaten. 
Recalling the percentages of animal and vegetable food taken by 
the four specimens first mentioned, we find that here also the 
former is almost exactly seven times the latter. This shows beyond 
question that the canker-worms eaten were in addition to the ordi- 
nary ratio of animal food taken by this species under the usual 
conditions.
