New insects injurious to agriculture. 



(Amer.Nat., Feb., 1882, xvi, pp. 151-152.) 



An abstract of a paper read at the Cincinnati meeting of the A. A. A. S. ; 

 8tat«8 that the occurrence of previously unnoticed noxious insects is due some- 

 times to the introduction of species from abroad, sometimes to previously- 

 existing unnoticed species, and at other times to the acquisition of new habits 

 by previously-known innoxious species. In the last case the acquisition of 

 new habits may be accompanied by the acquisition of new descriptional char- 

 acters, constituting of the insect a new species. New species may thus be- 

 come developed within brief periods of time.
