SEIUCORID.t:- HA L ONO TA. 141 



Pupa slender, red-brown ; in a cocoon in the eartli. 

 (Hoffmann.) 



This species regularly accompanies Penthina betuketana, 

 emerging from pupa almost at the same time, and frequent- 

 ing, more particularly, the birches which grow on open 

 heaths and bogs ; it is easily disturbed in the day time, and 

 flies with vigour a short distance ; but at dusk it is rather 

 later on the wing and more slow of flight. After dark it 

 will visit the sugar placed on tree-trunks to attract Noctuaj. 

 Widely distributed and to be found in suitable places 

 throughout England and the Lowlands of Scotland to 

 Moray; but I find no record for Wales; and for Ireland 

 only Kerry, Tyrone, and Antrim. Abroad it is distributed 

 throughout Central Europe, Scandinavia, Piedmont, and 

 Eastern Siberia, and in North America is recorded from 

 Maine and Massachusetts.
