Notes on Insectivorous Coleoptera. 
a fungus which forms small, black specks on dead wood, 
stems of weeds, etc. A third specimen from the same 
source had eaten some undetermined insect and about 
equal quantities of three elements ; viz., the above spores 
of Phoma, pollen and the anthers of grass (doubtless 
blue-grass upon which the insect was taken). A few 
clavate bodies were also noticed, consisting of a single 
row of nucleated cells — evidently the acrospores of some 
fungus. A September specimen was taken at Normal. 
Its crop was distended with an oily liquid, but contained 
no other visible food except a few acrospores of a fungus. 
This specimen had evidently been feeding upon animal 
food of some sort. 
Caiathns gr eg arius— Three individuals of this species 
were examined, all caught on blue-grass in blossom, by 
Mr. Webster, of Waterman, and Mr. McBride, of Free- 
land. The crop and oesoxjhagus of the first were dis- 
tended with a brown mass which proved to be wholly 
made up of the pollen and fragments of the anthers of 
grass. A second specimen contained a smaller amount 
of pollen and anthers of blue-grass, with minute frag- 
ments of a black and sparsely hairy insect. An antenna 
proved that it was a larva — probably a young caterpillar. 
The third contained traces of a similar larva and the 
fragments of the cornea of a perfect insect — evidently a 
remnant of some former repast. 
Anisodactylus baltimorensis. — The single specimen of 
this species had not recently taken food. The stomach 
was empty; but in the intestines was a large amount of 
chyme which possibly indicated liquid animal food. A 
specimen of A. ritsticus gave only similar negative re- 
sults. 
Anisodactylus sericeus. — A specimen taken in June 
showed fragments of anthers and pollen of grass, with 
other vegetable tissues, apparently derived from the 
seeds of grass. A small insect had also been eaten, as 
shown by particles much too few and minute for deter- 
mination. A second specimen had taken precisely similar 
food — the insect here being represented by a few facets 
of the cornea.
