SPECIAL NOTES. 
Prof. Forbes’ Sixth Report.—The Seventeenth Report of the State En- 
tomologist of Illinois has just been issued from the press of the State 
Printer at Springfield. It covers the years 1889 and 1890. Although 
tong 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 the Curculio; the American Plum-borer 
(Huzophera semifuneralis); 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-pune- 
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 avene, and concludes 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. Wiliam 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 cerealella), the Black Weevil (Calan- 
dra oryze), and the Red Grain Weevil (Silvanus cassie). Hementions 
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 
Pteromalus gelechie Webster, Carpophilus pallipennis, Calandra oryze 
(larva, pupa,and adult), Silvanus cassie (larva, pupa, and adult), S. swr- 
inamensis, and Tribolium ferrugineum.
