two "cotypes" which lack abdomens, all in the Fernald collection. 

 These are quite different in appearance from the paratype of exclama- 

 tionis, but all come well w^ithin the range of variation of our series, 

 and in it there are specimens which approach Walsingham's paratype 

 rather closely. An even more remarkable variation from the normal 

 is found in a specimen in our series from Aweme, Man. (Criddle) 

 which is small and dark, with the discal triangle conspicuous and a 

 very evident powdering of black scales on the primaries. Dr. McDun- 

 nough sent us for identification a second S from Aweme and two 

 females from Trenton and Ottawa, Ont., all of this dark, small form 

 and even more extreme than our specimen. The transition shown in 

 our series is so gradual that we think it useless to recognize any of 

 these forms by names. 



The specimens listed by Grinnell (Can. Ent. XL, 321, 1908) as 

 coloradcnsis proved to be a series of Platyptilia fragilis with a specimen 

 or two of albidorsclla. We do not know that cxclamationis reaches 

 southern California. 



The early stages have apparently not been studied.
