This species agrees fairly well with genuine specimens of this genus 

 obtained from Europe, except that there is a distinct areolet in ante- 

 rior wing. It is placed here only temporarily, however, as the dis- 

 tinct areolet will exclude it from this genu.s, and at present I can 

 find no other genus in whicli to place it.
