Observations on Insects. 129 



7. Different species of Phalaenae, the larvse of which 

 destroy the leaves, &c, of the common apple tree, 

 the Crab-apple (Pyrus coronaria), the Wild- cherry 

 tree (Prunus Virginiana), &x. 



8. Different species of Curculio, or Weavel, particu- 

 larly those which destroy the young fruit of the 

 peach, the plumb, the apricot, the nectarin, &c. 



9. The Zygaena Persies , and other insects, which 

 prove destructive to the roots, and branches of the 

 peach-tree. 



10. The Periodical Locust (Cicada septendecim), of 

 which some account is given in the First Part of 

 this Journal*. In the memoir, however, the author 

 has confined himself principally to an account of 

 the injuries inflicted by this insect, and the means 

 of preventing these injuries. 



11. The Crioceris Cucumeris, or Cucumber-Fly, 

 which commits such depredations upon the vines 

 of the cucumber, the melon, squash, and other 

 plants of the natural order Cucurbit ace a, as well 

 as upon other plants, not of this family. 



12. A species of Cimex, or Bug (perhaps the Cimex 

 htcmorrhous of Linnaeus), which also ravages the 

 cucurbitaceous vines, particularly the large ones, 

 such as the squash and pumpkin.
