128 Observations on Insects. 



1. A species of Cimex, which proves very destructive 

 to the wheat, the Indian-corn, and other important 

 vegetables, in Virginia, and other parts of the 

 United- States. 



2. A species of Phalsena, which destroys the Indian- 

 corn, in various stages of its growth. This is 

 called " Bud-Worm," &c. 



3. A species of Phalaena, which I call Phalsena migra- 

 toria. The larva of this, known bv the name of 

 " Grass-Caterpillar," &c, proves very destructive 

 to different species of gramina, or grasses, while 

 in their growing state, not neglecting the Indian- 

 corn. 



4. Another species of the same family of insects, 

 which has also destroyed the grasses, and the leaves 

 of the Sugar-maple, &x. 



5. Two species of Bruchus, viz. the common " Pea- 

 Bug" (Bruchus Pisi), which commits such dread- 

 ful havoc upon the common Garden-Pea (Pisum 

 Sativum), and another species, principally confined 

 to the southern parts of the United- States. 



6. The common striped " Potatoe-Fly" (Lytta vit- 

 tata of Fabricius ,, destructive to the Potatoe (Sola- 

 num tuberosum), and other vegetables, and so 

 beneficially employed as a substitute for the can- 

 tharides of the shops.
