SPECIAL NOTES. 



Prof. Forbes' Sixth Report — The Sevcuteeutli Report of the state En- 

 tomologist of Illinois has just beeu issued from the press of the State 

 Printer at Springfield. It covers the years 1889 and 1890. Although 

 long delayed, this report is welcome to entomologists, and contains the 

 usual array of excellent and well illustrated articles. The topics treated 

 are the Fruit Bark-beetle {Scolytus rugulosus)', the use of arsenical 

 poisons on Plum and Peach for che Curculio ; the American Plum-borer 

 {Euzophera semifuneraUs)', the common White Grubs; additional notes 

 on the Hessian Fly ; summary history of the Corn Root-aphis ; a bac- 

 teriological disease of the large Corn Root- worm ( Diabrotica 12-punc- 

 tata), and the diseases of the Chinch Bug. Most of these topics have 

 been treated by Prof. Forbes in more or less ephemeral publications 

 during the past three years, and are now for the first time put into per- 

 manent shape. The report is prefaced by three excellent colored plates 

 by the Art Publishing Company of Boston, illustrating Aphis maidis, 

 Aphis maidi-radicis, and Siphonophora aveme, and (joncludes with four 

 plates in black and white, illustrating some of the other insects treated. 

 As an appendix to the report an analytical list of the entomological writ- 

 ings of the late Dr. William LeBaron, second State Entomologist of 

 Illinois, is published, together with a half-tint portrait of Dr. LeBaron, 

 which we find very good and natural. 



Insects injurious to stored Grain — Mr. H. E. Weed, Entomologist of the 

 Mississippi Experiment Station, has just published a little 16-page bul- 

 letin devoted to the subject of stored-grain insects. He finds that the 

 principal insect pests which affect stored grain in Mississippi are the 

 Angoumois Grain-moth {Gelechia cerealeUa), the Black Weevil {Calan- 

 dra oryzce), and the Red Grain Weevil [Silvanus cassice). He mentions 

 several other wide-spread species, and recommends the ordinary bisul- 

 phide of carbon treatment in quarantine bins. The popular idea of the 

 efficacy of China berries has received a careful test with the same neg- 

 ative results obtained by us in 1878-'80. Original figures are given of 

 Pteromahis gelecJme Webster, Garpophilus palUpemiiSy Galandra oryzce 

 (larva, pupa, and adult), Silvanus cassice (larva, pupa, and adult), aS'. siir- 



inamensiSj and TrihoUum ferruyineum.
