Notes on Insectivorous Coleoptera. 
Harpalus caliginosus. — A single individual, running 
free upon the ground, had gorged itself with plant and 
animal food — apparently about three times as much of 
the former as of the latter. In the crop were a few hairs 
of a caterpillar and much half-digested muscle, with 
spores of fungi, a little epidermis of some graminaceous 
plant and a few pollen grains of Composite. In the stom- 
ach was a great deal of chyme, with fragments of the 
wings and tarsi of some minute dipter, more pollen of 
Composite and some vegetable parenchyma, apparently 
derived from unripe seeds of grass. In the ileum and 
colon these last-mentioned tissues predominated, al- 
though the latter contained also a large quantity of pol 
len of Composite indistinguishable from that of ragweed 
(Ambrosia). Here were also found two feet of a larva — 
possibly of the previously mentioned caterpillar. It is 
worthy of notice that these Harpali were full of eggs, of 
which there were about six in each abdomen. The crop of 
the second specimen, taken at Normal, in September, was 
distended with a brown, oily fluid, containing no recogniz- 
able material. In the intestine was a small mite and con- 
siderable vegetable parenchyma, apparently derived 
from some young seeds or ovules of plants. A little par- 
allel-veined vegetable tissue was also seen, evidently 
derived from grass. 
Harpalus herbivagus. — A specimen of this beetle, taken 
by Mr. McBride in July, was filled with cryptogamic veg- 
etation which had the form of a dense mat of slender 
branching tubes enclosing many spherical cells. This, 
Professor Burrill, to whom one of the slides of this ma- 
terial was referred, regarded as a fleshy or cartilaginous 
fungus with Palmella cells, although lie thought that it 
might have been derived from a lichen. A second speci- 
men, obtained by Mr. Webster, in March, had evidently 
been feeding on the young shoots of grass. 
C rat acanthus dubius. — One of this species, taken at 
Normal, in August, contained no apparent food except a 
few spores of fungi. In the stomach were great numbers 
of Gregarina, apparently of the same species as those 
found in Harpalus pennsylv aniens. In the colon, espc-
