326 LEPIDOPTERA. 



Pupa stout, taperiug considerably toward the tail ; anal 

 segment with a long slender spike ; colour reddish-purple, 

 with a bluish efflorescence like a ripe plum. (C. Fenn.) In 

 a rather loose cocoon under moss or dead leaves on the 

 ground or among loose earth. 



The moth hides by day in elm-trees, and may occasionally 

 be beaten or shaken out. At night it comes readily to light, 

 also to sugar and honeydew. It appears never to travel far 

 from its favourite elms {Ulmus campestris), and used to be 

 very common in the London suburbs, and its larva a familiar 

 object, crawling on the ground under them, or on their 

 trunks. Now it seems to have removed farther into the 

 country, but to be found in suitable places pretty commonly 

 all over the South, East, and West of England, and more 

 locally in the Midland Counties and Yorkshire, becoming 

 rare in Lancashire and Cumberland. I have no record for 

 Scotland, but in Wales it has been found near Swansea ; and 

 in Ireland very rarely, single captures being on record in 

 the Dublin district, Wicklow, Galway, and even Derry. 

 Abroad it ranges through Central Europe, Southern Sweden, 

 Southern Russia, Northern Italy, Corsica, and Spain ; and 

 since it is found in Japan, some extent of distribution in 

 Asia is probable.
