I hope these observations will prove a spur to gentlemen more 

 conversant in entomology and agriculture than myself, to excite 

 them to inquire into this subject, the result of which must ul- 

 timately be beneficial to the public at large, by discovering 

 some means of preventing the injury done by these mischievous 

 insects. At present we know of no other than early ploughing, 

 which is not always convenient to the farmer, as he wants to 

 feed his clover land as late as the season will admit of. Un- 

 slaked lime has been tried without success*; although it is well 

 known, if laid thick upon the land and ploughed in immediate- 

 ly, it will destroy insects of every kind, that are in the soil ; but 

 in many places the expense of procuring lime is too great to 

 think of using it in sufficient quantities to answer the intended 

 purpose-)-. 



As the drawing is from the accurate pencil of Mr. Sowerby, 

 no description of the insect is necessary.
