PART II. 



Subfomily DASYCHiRiE Hiibner. 



Following the law of priority the usual name Liparidse Boisd. must 

 be dropped for Hubuer's terra Dfm/chirs&. This is group " D " " Larrae 

 FascieulatfB " of Deuis aud Schiflfermiller (W. V.). In 1816 it was 

 clearly circumscribed by Hiibner in the '• Verzeichniss bekannter 

 Schmetterlinge" forming " Strips II Hi/pogymnise, Strips III Leiicomse 

 and Strips IV Dasi/cMrse" of his second " Tribus." As thus limited 

 by this author we find the group a perfectly natural one, no genera be- 

 longing to the neighboring groups being found in it. We have selected 

 the name of the last strips for the subfamily name, since it contains the 

 more typical genera.

On comparing the males of this species with two specimens of 0. 

 antiqua received from Professor Zeller of Meseritz, Prussia, I find 

 that, as Dr. Fitch remarks, our species is slightly darker both above 

 and on the under side of the body than its European representative. 

 This species has occurred to me abundantly at Brunswick, Me., where 

 I have never taken 0. leucostigma, but simply seen it on the wing, Oct. 

 5. It flies in the hot sunshine early in September. Mr. Sanborn has 

 given me a specimen less than half the usual size. Norway, Me., Smith
