LARENTIDAZ—EUPITHECTA. 5 1 



sprinkled with a few reddish hairs. Varying to pale reddish- 

 brown, with the dorsal line and blotches dingy olive, and the 

 subdorsal lines dusky and very indistinct ; or to a dark, dingy 

 olive ground colour. (Eev. H. H. Crewe.) 



September and October on Mugwort {Artemisia vnhjaris), 

 feeding at night on the upper surface of the leaves, and 

 leaving the cottony undersurface almost untouched; also 

 occasionally upon A. maritima (sea vpormwood), tansy, and 

 even wild camomile. During the day it is seldom to be 

 found on the upper green leaves of the plant but loves to 

 hide among the twisted dead leaves below. 



Pupa dull brown, with the wing-covers green or olive- 

 green. In a cocoon of silk and earth, in the ground. 

 In this condition through the winter. 



The moth is seldom seen in the daytime ; doubtless it 

 hides among its food plant, in the large masses of which it 

 would be well concealed ; at late dusk it flies over the same 

 plants, and on into the night, and will come occasionally to 

 a strong light. It seems decidedly to prefer the coast dis- 

 tricts, though not confined to them, and has been found in 

 Kent, Sussex, Surrey, Dorset, Devon, Cornwall, Somerset, 

 Berks, Middlesex, Oxfordshire, Essex, Gloucestershire, Here- 

 fordshire, Cambridgeshire, Suffolk, Norfolk, Cheshire, Lan- 

 cashire, Yorkshire, and Durham. In Wales Mr. H. W. 

 Vivian has taken it in Glamorganshire, and I have found it 

 rarely in Pembrokeshire. In Scotland the only record seems 

 to be from Ardrossan, in Ayrshire. In Ireland it has been 

 found on the Dublin coast at Howth, also in the Isle of 

 Larabay, in Louth, and Armagh. Abroad it has a wide 

 range, through Central, and (temperate) Northern Europe, 

 North Italy, Dalmatia, Southern Eussia, Bithynia, and the 

 mountainous regions of Central Asia. 



This species was united with the following by Mr. Stainton 

 in his "Manual," doubtless because of the existence of dark 

 forms of both, which seemed to form connecting links. They
