crop can be saved by spraying; a second contribution to the knowledge 

 of the life history of the Hessian fly, indicating that the development 

 of a third brood of larvae may sometimes detract from the effect of late 

 sowing; the life history of the u Wheat Bulb-worm" (the American 

 Meromyza) showing three broods in Illinois; Mr. Weed's article upon 

 an outbreak of injurious locusts in Illinois (the same paper as read be- 

 fore the Society for the Promotion of Agricultural Science in 1888) and 

 an article by the same author upon some common insects affecting the 

 foliage of young Apple trees in the nursery and the orchard. There is 

 an appendix by Professor Forbes on the present condition and prospects 

 of the Chinch Bug in Illinois which was summarized on page 222 of Vol. I 

 of Insect Life. The only illustrated article is that by Mr. Weed 

 upon Apple insects. 



The fifth report is more extensive, covering 104 pages and includes 

 three chief articles, viz : Studies on the Chinch Bug, II, the Corn Bill- 

 bugs, and .Notes on Cut Worms. The report is illustrated by six beauti- 

 ful heliotype plates, two and one-half devoted to Bill Bugs, and the others 

 to Cut Worms, the Wheat Thrips, and the Burrowing Web- worm (Pseuda- 

 naphora arcaneila). Professor Forbes gives an excellent account of 

 former observations upon the species of Sphenophorus, ordinarily known 

 as Bill Bugs. As an appendix to the report, an extensive analytic 

 economic bibliography of the Chinch Bug from 1875' to lb88 is given, 

 covering one hundred and twenty-two pages. It seems to be as full 

 and complete as great pains can make it. 



Mr. Whitehead's third annual report* has also just been published. 

 It includes a consideration of some thirty topics, several of which are also 

 considered in Miss Ormerod's report. The articles are all short, nearly 

 all are illustrated, and though containing little that is original, the re- 

 port, as a whole, is well adapted to the use of British farmers and 

 gardeners. 



Work at the Cornell Station — Professor Comstock, in Bulletin 15 of 

 the Cornell Agricultural Experiment Station, December, 1889, entitled 

 " Suudry investigations made during the year," gives an account of 

 the Apple-tree Tent-caterpillar (Clisiocampa americana). Though this 

 is a well-known insect, yet, on account of its great increase of late years 

 as a pest, a brief restatement of its habits is not at all out of place. 



Iu the second annual report of the Station, for the year 1889, Pro- 

 fessor Comstock presents an outline of his work as entomologist for 

 the year. The Wheat Saw-fly (Cephus pygmams) has been studied and 

 the i( clematis disease "has been determined to be due to Heterodera 

 radicicola, the same Nematode worm, of the family Anguillulidre, which
