BOARMIDjE—MACARIA. 379 



tawny-brown, and in the fore wings is suddenly extended, in 

 part, to the hind margin ; above this the apical area is 

 silvery-white dotted with brown and purple-grey ; cilia all 

 yellowish white clouded and dashed with smoky-black. Body 

 and legs pale drab ; tarsi pale brown. 



Usually very constant in colour and markings, though the 

 slate-grey of the wings fades rapidly even during life ; but 

 there seems to be a tendency to variation in the Western and 

 Midland districts ; a striking variety found occasionally in 

 Delamere Forest, Cheshire, is of a suffused, smoky black- 

 brown colour with the lines obscured, but the tawny trans- 

 verse band ill-defined and extended toward the costa into a 

 rusty blotch. A very striking example of this form is lent me 

 by Mr. F. N. Pierce. A somewhat similar variation has been 

 obtained by Mr. F. C. Woodforde in Salop. A specimen in 

 the collection of Mr. S. J. Capper has the three transverse 

 lines of the fore wings and two upon the hind wings much 

 intensified ; and the late Mr. W. G. Blatch took at Knowle. 

 near Birmingham, one which has upon the fore wings four 

 such lines. 



On the wing in June and July, or even occasionally as 

 early as the end of May ; and as a very partial second genera- 

 tion, in favoured localities, in August and September. 



Larva rather slender, smooth and even in thickness ; head 

 rounded, green, the lobes edged and barred with black ; 

 body dark green ; dorsal line indistinctly darker, darkest at 

 the divisions of the segments ; subdorsal lines, two in number, 

 white, the lower edged with a very dark green spiracular 

 line, below which is a more slender similar line ; under- 

 surface and legs paler green. When younger lighter green 

 with three white subdorsal lines and a yellowish white line 

 below the spiracles. The resemblance of this larva to a 

 little bundle of leaves of its food plant is, at all ages, extra- 

 ordinary. 



July and August, possibly sometimes in September and
