Notes on Insect imrous Coleopfera. 1.73 



tember, had eaten a brown beetle of medium size, the fraj:;- 

 ments of which filled the whole alimentary canal. From 

 the general appearance of these, from the tips of one ante- 

 rior and one middle tibia and from a maxillary palpus, it 

 was inferred that this beetle was one of the Scaraba'idav 

 A fragment of a mandilde showing a ridged masticatory 

 surface, made it likely that it was a vegetable feeder. 

 There was no trace of vegetable food in this Evarthrus. 

 Another specimen, taken at Normal, in September, had 

 eaten a large Coleopterous larva and two minute, indeter- 

 minable insects. Traces of confervoid Algw were also dis- 

 covered in the intestine. 



Pterostiehus sayi. — A si)ecimen of this species, taken at 

 Normal, in September, was full of the remains of an un- 

 recognized hairy insect with two tarsal claws. 



Pterostichns Incuhlandus. — This specimen, taken like- 

 wise at Normal, in September, contained a multitude of 

 fragments of some Hymenopterous insect, including a max- 

 illary 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. 



ChlcBnius tonientosus. — One of this species, taken at Nor- 

 mal, in September, contained traces of insect food not oth- 

 erwise determined, and a nematoid parasite. 



Chlo&nius diMnis. — A specimen of this species, taken 

 under a log, near Normal, in Sej^tember, contained traces 

 of some crustaceous insect, with pieces of vegetable tissue 

 (apparently wood) penetrated by the mycelium of a fun- 

 gus. 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 diGhrous. — A specimeti, taken at Bloom ing- 

 ton, in September, had eaten insect food not otherwise 

 determinable. 



Twenty-eight specimens of Oarabidae, representing sev- 

 enteen species, are here reported. It will be seen that twen- 

 ty-one specimens, belonging to fifteen species, had eaten 

 animal food, and that twenty specimens, belonging to elev- 

 en species, had eaten vegetation of some sort. I estimat-
