of you to do something, however Httle, to keep up the reputation that 

 we have gained. 



We have the finest field in the Dominion of Canada for the prosecu- 

 tion of our studies, and there are many perplexing problems waiting 

 to be solved. In Leptarctia californiae and its varieties, to determine 

 if any males can be produced that have red secondaries; all the males 

 that I have seen have yellow ones and the females red, although Dr. 

 McDunnough assures me that he has a red male. In the genus Alypia, 

 Sir George Hampson, in his synopsis of the species, differentiates 

 between octomaculata hind wings marked with white and langtoni hind 

 wings marked with yellow. The species that we have are all listed 

 under the name of langtoni, although in all the specimens that I have 

 seen the males have hind wings marked with white and the females 

 marked with yellow. By breeding we could determine if this was only 

 a sexual and not a specific difference. Again we have a species called 

 Hadena arctica, which Dr. McDunnough claims to be a variety of 

 Hadena castanea. I am of the opinion that it is a western race of the 

 eastern arctica, but by breeding castanea and so called arctica from the 

 eggs of known females, this point could be definitely settled for all 

 time. There are a number of other instances which I could give you 

 along the same lines, but I think these are sufficient to show you that 

 if our systematic members would each take up one of these subjects and 

 carry it to a successful conclusion, they would accomplish something 

 that would add to their credit and be of great taxonomic value to the 

 entomology of Boreal America.
