THE FOOD RELATIONS OF THE CARABID.'E AND COCCIN- 

 ELLID.F:. By S. A. Forbe.s. From Bulletin No. 6. 111. State Lab. 

 of Nat. Hist., Normal, 111, Jan., 1883, 8vo., pp. 31. 



Through the kindness of tlic author, we have been favored \\ ith a copy 

 of the above paper, which embodies the results of a very laborious series 

 of microscopic examinations of the contents of the alimentary canal of insects 

 belonging to the Carabidre and Coccinellidai. \\\ the Carabida; the results of 

 the dissection and study of 175 specimens are given, representing 38 species 

 and 20 genera. Of the CoccinellidK, the results of the dissection of 39 

 specimens are given, accompanied by carefully compiled tables presenting 

 the evidence in the most convenient and accessible forms. Prof Forbes' 

 e.xperiments show clearly that the opinions hitherto held by Entomologists 

 as to the food of these insects are in many respects incorrect. While it is 

 shown that the insects belonging to the genus Calosoma live almost 

 exclusively on animal food, those of Chkenius and Galerita to the extent 

 of nine-tenths, and those of Pterostichus three-fourths ; the species of 

 Harpalus take only about 12 per cent, of animal food, Anisodactylus 21 

 per cent.. Amara and Amphasia 2-^ per cent., and Agonoderus about '^2> 

 per cent.: the whole series of Carabidai examined averaging 57 i)er cent, 

 of animal food, the remainder being vegetable and consisting mainl\ of tlie 

 pollen of flowers and the spores of fungi.
