Glassy Cutworm (Hadena devastatrix Brace), Y'ellow-headed Cutworm 

 (H. arctica Boisd.), Greasy Cutworm (Agrotis ypsilon Rott.), Variegated 

 Cutworm (A saiccia Hiibn.), Spotted Cutworm (Noctua c-nigrum Linn.), 

 Dingy Cutworm (Feltia subgothica Haw.), Striped Cutworm (F. j a cut if em 

 Guen.), Clay-backed Cutworm (F. gladiaria Morr.), Bronze Cutworm 

 (Nephelodes minians Guen.), W-marked Cutworm (Noctua clandestina 

 Harr.), Granulated Cutworm (Feltia annexa Tr.), Dark-sided Cutworm 

 (Euxoa messoria Harr.), Common Striped Cutworm (E. tessellata Harr.), 

 Red-backed Cutworm (E. ochrogaster Guen.), Bristly Cutworm (Mamestra 

 renigera Steph.) ; several Root Web-worms which hide away in silken 

 burrows during the day and feed on the plants when quite young at night, 

 often causing widespread injury (Crambus mutabilis Clem., C. trisectus 

 "Walk., C. luteolellus Clem., and C. vulgivagellus Clem.) ; of less im- 

 portance are the burrowing Web- worms Anaphora popeanella Clem., 

 Pseud anaphora arcanella Clem., Hypoclopus mortipcnnellus Grote. The 

 Stalk-borer (Papaipenia nitela Guen.), the Corn-worm (Heliothis armiger 

 Hiibn.), and the Army-worm (Leucania unipuncta Haw.), complete the 

 list of the Lepidoptera doing injury to corn. Among Coleoptera the 

 following Corn Bill-bugs are troublesome : Sphcnophorus parvulus Gyll., 

 S. venatus Say, S. ochreus Lee, S. pertinax Oliv., S, cariosus Oliv., 

 S. scoparius Horn., »S'. sculptilis Uhl., and S. robustus Horn. Of other 

 insects the Chinch Bug (Blissus leucopterus Say) and various Grass- 

 hoppers are fully described. Some others, like the wire-worm and 

 May-bug, have been dealt with in earlier bulletins. In each case suitable 

 means for lessening the danger of attack are mentioned. — F. J. C. 



Insecticides and their Use. By J. B. Smith (U.S.A. Exp. Stn. 

 Neiv Jersey, Bull. 169). — Recipes and directions for use of various insecti- 

 cides, all of which have recently been referred to in these abstracts.

Insecticide Use of Gasoline Blast Lamp. By S. A. Forbes 

 (U.S.A. Exp. Stn. Illinois, Bull. No. 89, 11/1903).— The ordinary 

 plumber's torch is probably the most dangerous to vegetation of any 

 insecticide apparatus which has ever been brought forward for common 

 use. The margin of safety must be in most cases very narrow. It 

 might, however, be usefully employed in the destruction of those insects 

 that can be lured on to a valueless crop away from a valuable one, and 

 might perhaps be tried for the destruction of chinch bugs as they come 

 out of small grain for their midsummer invasion. — F. J. C. 



Insects, Destructive, in the United States. By C. L. Marlatt 

 ( U.S.A. Dep. Agr. Year Book, 1904, p. 461). — It is asserted that in no 

 country in the world do insects impose a heavier tax on farm products 

 than in the United States. The losses resulting from the depredations 

 of insects on plant products exceed the entire expenditure of the National 

 Government. It is, however, stated confidently that the losses would be 

 much heavier but for the various methods of control, and attention is drawn 

 to these methods. The prevention of loss from the Hessian fly, due to 

 the knowledge of proper seasons for planting and other direct and 

 cultural methods, results in an enormous saving annually. Careful
