cially, scores of these parasites in the “ resting state ’ 9 
formed considerable masses which half filled the intes- 
tines. 
Evarthrus colossus . — One of this species, taken in Sep- 
tember, had eaten a brown beetle of medium size, the 
fragments of which filled the whole alimentary canal. 
From the general appearance of these, from the tips of 
one anterior and one middle tibia and from a maxillary 
palpus, it was inferred that this beetle was one of the 
Scarabaeidse. A fragment of a mandible showing a ridged 
masticatory surface, made it likely that it was a vege- 
table feeder. There was no trace of vegetable food in this 
Evarthrus. Another specimen, taken at Normal, in Sep- 
tember, had eaten a large Coleopterous larva and two 
minute, indeterminable insects. Traces of confervoid 
Algae were also discovered in the intestine. 
Pterostichus sayi . — A specimen of this species, taken 
at Normal, in September, was full of the remains of an 
unrecognized hairy insect with two tarsal claws. 
Pterostichus lucublandus . — This specimen, taken like- 
wise at Normal, in September, contained a multitude of 
fragments of some Hymenopterous insect, .including a 
maxillary palpus and a labrum nearly entire, with pieces 
of the legs and tarsi. This beetle had also eaten a small 
mite and a few acrospores of fungi. 
Chlcenius tomentosus . — One of this species, taken at 
Normal, in September, contained traces of insect food 
not otherwise determined, and a nematoid parasite. 
Chlcenius difinis . — A specimen of this species, taken 
under a log, near Normal, in September, contained traces 
of some crustaceous insect, with pieces of vegetable tis- 
sue (apparently wood) penetrated by the mycelium of a 
fungus. Large vegetable fragments were also seen, which 
Professor Burrill determined as pieces of a large, fleshy 
fungus. The stomach likewise contained acrospores of 
Dematiei. 
Bradycellus dichrous . — A specimen, taken at Bloom- 
ington, in September, had eaten insect food not other- 
wise determinable.
