I02 LEPIDOPTERA. 



Larva rather short and stout, with the extremities attenu- 

 ated ; dull red or liver colour, the raised dots shining horn 

 colour, each bearing a hair; head chestnut, dorsal plate 

 darker brown, broadly divided ; anal plate narrow, divided, 

 brown. 



April in the catkins of birch, which it completely hollows 

 out, lining the hollow with silk. 



Pupa in the larval habitation, or under dead leaves, in a 

 silken cocoon. 



The moth loves to sit during the day on the trunks or 

 branches of birch trees, and often looks very pretty and con- 

 spicuous on a birch-trunk in a suburban garden, though not 

 equally so on the white papery bark of the same trees. It 

 is lively and active, and not to be captured too easily unless 

 the weather is chilly. It flies rather late in the twilight 

 over the birch trees, and is not very easily seen on the wing 

 at that time. Not rare in the London parks and suburbs, and 

 to be found throughout England wherever birch trees are in 

 any plenty, doubtless also in Wales, though I have no records. 

 In Scotland it is just discovered by Mr. W. Evans in the 

 Edinburgh district, and is found in the Clyde valley, Perth- 

 shire and Aberdeenshire ; and in Ireland, in Kerry, Galway, 

 Sligo, Fermanagh, Armagh and Antrim. Abroad its range 

 is throughout Central Europe, Northern Italy, Scandinavia, 

 and Russia, 



Genus 20. LITHOGRAPHIA. 



Antennae short, ciliated ; palpi short, placed below the 

 head ; thorax very faintly crested ; fore wings rather broad, 

 costa folded to about one-third its length ; hind wings 

 smooth. 



We have four species.
