NORTH AMERICAN LEPIDOPTERA. 81 



In 188G in a very well wi-ittcn pamphlet on "The Sj)hingi(Ue of 

 New England," Prof. Fernald gives very carefnl and acenrate de- 

 scriptions of the genera and species of this section. Many of my 

 suggestions are adopted, while the Professor differs considerably in 

 his estimate of certain genera. 



The generic descri})tions are careful and con]})lete, and in this 

 paper I have drawn largely from them, finding them in almost every 

 instance absolutely correct. Characters not noted by previous au- 

 thors are here fully described, and the papei", limited as is its scope, 

 is a positive and valuable addition to our knowledge. As far as 

 possible the descrijDtions of the early stages are also given, and to the 

 beginner this little pamphlet is invaluable, as it is clear and simple, 

 and yet scientifically accurate.
