THE CANADIAN ENTOMOLOGIST. 271 



the food found in the alimentary canals of 82 individuals, belonging to 18 

 genera and 32 species, was of a vegetable character. Collections not 

 made by the writer, and coming from an orchard seriously affected by 

 cankerworra, 71 specimens, and 10 from a field infested by chinch bug, 

 and others from a cabbage patch that had been attacked by cutworms, 

 indicated, in most cases, the partiality of the Carabidae for animal food, 

 where this was abundant and easily obtainable (12th Report State 

 Entomologist of Illinois, pp. 105-116). 



In 1885, Agonoderus pallipes was reported to the U. S. Department 

 of Agriculture, from Illinois and Iowa, as damaging young corn by 

 gnawing the seed kernels and eating the sprouting roots (Bull. 12, O. S., 



U. S. Dep. Agr., Div. Ent., pp. 45-6, 1886), similar reports of injury 

 coming also to the writer from farmers in Indiana during the same year. 

 Since that time it has also been reported to me as working a like injury 

 in Ohio. 



In 1886, Dr. J. A. Lintner reported injury to the foliage of the 

 strawberry by Beinbidiutn qtiadrimaadatinn^ in Connecticut (3rd Report 

 State Ent., N. Y., p. 98). 



From all of this it would appear that many of our Carabidie are 

 naturally, and by preference, of carnivorous habits, but during a scarcity 

 of this kind of food, can subsist upon that of vegetable character. 



PARTIAL LIFE-HISTORY OF DICHOGAMA REDTEN- 



BACHERI, LED. 



EV HARRISON G. DYAR, WASHINGTON, D. C. 



The Pyralid genus Dichogama has not yet been reported from United 

 States territory on the mainland, but at least three species occur in 

 southern Florida. The following notes were made on the larva of one of 

 them, D. Redtenbacheri. 



Stage II. (?) — Head flat before, clypeus high, mouth pointed ; 

 luteous, ocelli black ; width .4 mm. Body a little flattened, translucent, 

 yellowish, a geminate lateral brown stripe. Cervical shield large, colour- 

 less, brown dotted on the tubercles and on lateral edge : anal plate small, 

 not marked. Tubercles small, brown ; sette long, stiff, pale. Skin 

 sparsely granular ; segments scarcely annulate. 



Stage III. — Head whitish with streaks of brown dots on the lobes 

 converging to clypeus, mouth brown ; width .7 mm. Body flattened, green 

 from the food ; a double broken lateral black band reaching from the 

 spotted cervical shield to the colourless, spreading anal feet. Feet all pale.
