 Scoparia atropicta Hampson, Trans, ent. soc. Lond., 233, 1897. 

 Scoparia atropicta Fernald, Bull. 52, U. S. Nat. Mus., no. 4506, 1903. 



Sir George Hampson has kindly sent me a figure of this species, 

 which shows a form unlike anything known heretofore from North 

 America. He says the label is " Am. Sept. 5, iv, Mus. Z. Mschl 5, 

 79." but adds that the locality is probably a mistake and the species 

 is the same as S. exhibitalis Walker from Australia. I believe this to 

 be correct and, with this explanation, drop the name from the Amer- 

 ican list.
