SXOUT-BEETLES, Rhynchophora 5 



The whole vegetable kingdom and every part of each plant serve 

 as food for insects, 5 Enumeration of insects affecting the dif- 

 ferent parts of the apple-tree, 5 Other food-habits of insects, 7 

 Vast extent of the science of entomology, 8 Beauty and sim- 

 plicity of classification in entomology, 8 Each family distin- 

 guished by its general appearance, 8 Unity of habits in each 

 family, 9 Distinguishing characters of snout-beetles, 9 Their 

 larvte, 10 They are among the most injurious beetles, 10 In- 

 jurious snout-beetles in Europe, 11. 

 The common plum Curculio, Conotrachelus nenuphar 11 



It is single-brooded, 11 Experiments to prove this fact, 12 It 

 hibernates as beetle, 13 Form of the egg, 13 Feeding habits of 

 the beetle, 13 Creaking noise produced by it, 14 Stridulation 

 in other insects, 14 It is nocturnal rather than diurnal, 14 

 Habits of the beetle at night, 14 Remedies, 15 The Ransom 

 chip-trap process, 15 ; explanation of the process, 15 ; it is not so 

 successful as anticipated, 15 ; it is not a new discovery, 16 ; num- 

 ber of Curculios caught by it, 16; its success dependent on the 

 character of the soil, 17; directions for using the process, 17; 

 more experiments needed, 17 Offering premiums for collecting 

 specimens, 17 Absurdity of the application of Paris green for 

 the Curculio, 18 Jarring by machinery, 18 The Hull Curculio- 

 catcher defective in several respects, 18 The Ward Curculio- 

 catcher, 20; how it could be improved, 20; rules for using the 

 machine, 21 Curculio-catcher invented by Claxton & Stevens,

 operation, 24 Two true parasites of the Plum Curculio, 24 The 

 Sigalph us Curculio parasite, 24 ; Fitch's account of it, 25; Walsh's 

 doubt about its being parasitic on the Curculio, 25 ; experiments 

 and observations proving that it is a parasite of the Curculio, 

 25; its development and frequent occurrence around St. Lonis, 

 25 ; it attacks also other soft-bodied larvae, 26 ; points in its nat- 

 ural history, 26; its position in the system, 27; description of
