This is a very beautiful species, and worthy the name which 

 it bears. 



I desire to make my acknowledgments to Mr. Gulick for a 

 loan of his typical specimens, by which I have been enabled to 

 compare his with the species described by other authors. 

 There is much difficulty in fixing the boundary of varieties, and 

 much must necessarily be left to arbitrary opinion. I have 

 given my own convictions, after ample opportunities for 

 observation and study, but do not claim fur myself absolute 

 accuracy in my powers of discrimination. Those who choose 

 to differ from my conclusions are at full liberty to use their 

 own judgment or opinions, and to draw from this article only 

 such aid as they may find useful.
