220 THE CANADIAN ENTOMOLOGIST. 



the entomological writings of the late Dr. Asa Fitch, a list of the insect 

 enemies of the apple-tree, descriptions and notes of Lepidoptera, on the 

 life duration of the moths, followed by a very complete general index 

 covering ^;^ pages, with an additional index to food plants. We have had 

 many excellent reports from Staie Entomologists in the past, but we doubt 

 if ever there was a report published containing so much useful information 

 and so well arranged in every respect as this first report of Prof. Lintner's. 

 The State of New York may well be congratulated in having secured the 

 services of an officer so efficient and painstaking. 



Twelfth Report of the State Entomologist on the Noxious and Beneficial 



Insects of the State of Illinois. 



This twelfth Illinois report is the first of the recently appointed State 

 Entomologist, Prof. S. A. Forbes. It is a large octavo pamphlet of 162 

 pages, illustrated with 30 cuts. An exhaustive account is given of the 

 corn-root worm, Diabrotica lofigicor?iis, Say, with magnified figures of the 

 insect in all its stages, together with details of the injury it has inflicted. 

 This is followed with an account of the remedies, both natural and arti- 

 ficial, wliio.h have been found useful in subduing this pest. The Chinch 

 bug, B/.'ssus Icucopterus, is next noticed, its life history given, and natural 

 enemies enumerated, including a species of bacterium, Micrococcus insec- 

 toruiii, which has been found destructive to the Chinch bug in the west. 



I'he strawberry crown borer, Tyloderma fragaria, is described very 

 fully, and its work illustrated ; also the crown miner, Anarsia liueatella. 

 Following these are descriptions of the melon plant louse, ApJiis cucmn- 

 eris, n. sp., which has been found injuring cucumbers and melons ; the 

 European cabbage worm, Fieris rapce, with details of experiments with 

 various remedies. The cherry or pear slug, Sela?idria cerasi ; the white- 

 marked tussock caterpillar, Orgy i a leucostigma, the bag-worm, Thyri- 

 dopteryx ephemerceformis ; the army worm, Leuca?iia nnipuncta; the 

 stalk-borer, 6^t?r/'j//rt; nitela ; and the zebra caterpillar, Mamestra picta, 

 are also described, following which is an interesting article on the food 

 relations of predaceous beetles, a subject to which Prof. Forbes has de- 

 voted much attention. Next in order is a paper on the Phytopti and 

 other injurious plant mites, by H. Garman, and observations on the 

 angoumois grain moth and its parasites, by F. M. Webster 3 the whole 

 forming an excellent report, one which well sustains the character to which 

 the Illinois reports have attained.
