lines also faint and obscure; close to the hind margin are 

 three black dots ; cilia brown, shading to smoky black. 

 Hind wings dark brown with a reddish flush ; cilia dull 

 white. Female similar, the costa not folded 



Underside of the fore wings smoky brown, shaded 

 behind with pale yellow ; dorsal mai-gin white. Hind wings 

 pale brown, with a yellow flush. 



On the wing in July and August. 



Larva cylindrical ; dirty white, with an irregular dark 

 internal dcrsal vessel ; head light brown ; dorsal and anal 

 plates faintly brownish. 



October to May or June ; in the root-stocks of Artemisia 

 vulgaris (mugwort), feeding under the bark, sometimes in 

 little companies of five or six together. 



Pupa bright brown, in a cocoon within the larval burrow. 



Rather a sluggish species, sitting during the day in the 

 plants of mugwort, from which it is easily disturbed in the 

 warm sunshine, but merely flies about the same plants and 

 settles again. At sunset and till dusk it moves about of its 

 own accord, but is never very active, and rarely leaves the 

 neighbourhood of its food-plant. Not uncommon in the 

 London suburbs, and to be found in the southern counties 

 from Kent to Devon and Somerset, also Berks, Oxfordshire? 

 Herts, the eastern counties to Norfolk ; and in Hereford- 

 shire, Worcestershire, Cheshire, and Lancashire ; but I find 

 no record in the north of England nor in Wales ; though in 

 Scotland it is recorded from Aberdeen and Moray, and Mr. 

 W. Dale says in the Hebrides. In Ireland, the only capture 

 of which I have any knowledge is that of Canon Cruttwell 

 at Renvyle, Galvvay. Abroad it is found throughout Central 

 Europe, and in Sweden and Livonia.
