In eight out of twelve Xortli American adult specimens, there is but the 

 slightest amount of spotting on the breast ; in two of these (4,.36fi, Paget 

 Sound, and 12,014, Oregon), none whatever; in 17,228 (<?, Cape St. Lucas), 

 2,512 ((? S. F. B. Carlisle, Pa.), .34,065 ( 9 , Realejo, Central America), and 

 5,837 (Fort Steilacodm), there is just a trace of these spots. 



The specimens described are those having the breast most distinctly 

 spotted. Specimens vary, in length of wing, from 17.50 to 20.50. There 

 appears to be no sexual difference in size.
