334 EEPORT OF THE SECRETARY OF THE 



such reports were not based on facts, and that we may never 

 expect to subdue this insect by the jarring process. It is not 

 as timid or as much inclined to drop as the Plum Curculio, 

 and, though it can occasionally be brought down, it generally 

 remains defiantly on the fruit or on the bough, through the 

 gentlest as well as the severest jarring of the tree. Indeed, its 

 habit of transforming in the fruit, places it in a great measure 

 beyond our control, and I fear that this is one of the few 

 insects with which we can do but little by artificial means. 

 But we have only just commenced to understand this foe, and 

 there is much yet to learn about it. I sincerely hope that the 

 few facts which have been here given, will increase your 

 interest in this insect, and enable you to carry on future 

 observations and experiments with a better understanding; so 

 that they will at last result in making us masters of this 

 rather difficult situation. Mr. H. Lewelling of High Hill, 

 Montgomery county. Mo., who has had much of his fruit 

 injured by this insect, informs me that Tallman's Sweet is 

 preferred by it to all other varieties, and our observations 

 should, as much as possible, tend in the direction of deciding 

 which varieties are most subject to, and which most exempt 

 from its attacks ; and which varieties fall most readily when 

 infested by it. For it is obvious that with our present knowl- 

 edge, the only real remedy which yet exists, is the destruction 

 of the infested fruit, whether upon or ofi" the tree ; and it may 

 turn out that although we cannot jar down the beetles we can 

 jar down much of the infested fruit, which would, without 

 jarring, remain on the trees. 



Anthonomus quadrigibbus, Say — Larva (Fig. 8, h) — Average dorsal 

 length when full grown 0.45 inch ; soft and white, with a very few 

 sparse soft hairs ; arched and wrinkled Lamellicorn-fashion, the space 

 between the wrinkles, and a distinct dorsal vascular line, bluish-black. 

 Head free and almost perpendicular, yellowish-brown with the mandibles 

 darker. A pair of polished ventral tubercles on each of the three thor-
