Mr. J. W. Douglas's Description^ Sfc. 21 



IV. Description of a new British Moth. By J. W. 

 Douglas, Esq., M.E.S. 



[Read 1st February, 1847.] 



Family TORTRICID.E. 



Genus Anchylopera, Stephens. 



Anchylojoera suharcuana, Douglas. (PI. II. fig. 4.) 

 Head and palpi white. Upper wings somewhat falcate, dull 

 ferruginous, having a darker flexuous line extending down the 

 centre from the base, about two-thirds of the length, forming a 

 small arch in the middle of the wing, and then continued angu- 

 larly to the apex. The base of the costa is ashy white, and the 

 colour is much lighter along the lower edge and within the pos- 

 terior angle. Lower wings rather dusky. Body griseous. Ex- 

 pansion of wings about six lines. 



This is a very distinct species, and is intermediate between 

 A. biarcuana and diminutana, from both of which however it may be 

 known at a glance by its white head and palpi. I have only one 

 specimen, which I took May 12th, 1844, at Wimbledon Common. 

 Mr. S. Stevens has a specimen which differs from mine in having 

 the upper wings narrower and darker, but I believe it to be this 

 species. Mr. Henry Doubleday also informs me that he has one 

 taken near Whittlesea Mere last September, so that it would 

 appear to be double brooded. I may add that M. Guenee has 

 seen my specimen and that it is new to him.
