THE CANADIAN ENTOMOLOGIST. 233 



the National Museum collection it became necessary to examine some of 

 the species for determination, and the facts gleaned in this way were 

 noted. The localities given are very incomplete, as here I failed. I 

 neglected localities for structure, and the list does not, therefore, give a 

 fair idea of the distribution of many of the species. 



The economic literature has been almost entirely omitted, since it 

 rarely became necessary for me to refer to it. Mr. Hy. Edwards's list of 

 the early stages will supplement the present catalogue in this respect. 

 The object sought here is to bring within reach of the student the 

 knowledge of where the literature of the family can be found, if he 

 desires to study it systematically. I have also given my own observations 

 which may serve as a starting point for others, and may aid in determina- 

 tion and a knowledge of the characters upon which the genera are based.
