 land. Iii Scotland, in Roxburghshire, Clydesdale, and other 

 parts of the south of that country, and, rarely, in suitable 

 spots, in the Moray district. Very scarce in Ireland, but has 

 been taken in Wicklow, Kerry, Galway, and Tyrone. 

 Common in all the temperate parts of Europe, and in Asia 

 Minor and Tartary. In China and Japan a form is found 

 of double the size of our specimens, but otherwise agreeing 

 most accurately, and apparently the same species. It is 

 known as P. Sinica. 



Genus 7. PTILOPHORA. 



Antennae of the male with such long slender pectinations 

 as to be plumose ; fore wings narrow, thinly scaled, dorsal

 to sweep round the anal angle and dorsal margin — which is 

 very short, not more than one half the length of the costa, 

 and curved to near the base ; a short loose triangular mar- 

 ginal mass of scales forms a sort of prominent tuft, which lies 

 much nearer the base of the dorsal margin than usual. Very
