DEROTMEMA Scudder. 
haydeni Thos. This is a very common species throughout the State 
up to an altitude of about 9,000 feet, Light colored speci¬ 
mens that seem to be the true ciipidineiim of Scudder seem to 
me to grade insensibly into true haydeni , so I am including all 
under this name. Mr. Caudell distinguished cnpidineum by 
the narrower black band of the wings which does not seem to 
hold true in all the spread specimens I have examined.
