THE CHEVRON. 165 



middle of the back is a series of purplish-edged, brown-centred, 

 whitish, triangular markings ; the third ring is swollen, and has 

 a black collar. It feeds at night on the foliage of red and 

 black currant, also on gooseberry, and may be found in April 

 and May, earlier or later according to season, sitting by day 

 upon the bushes. 



The moth flies in July and August, and occurs in gardens, 

 but is said to be partial to sloe bushes and hedges. It is 

 always more or less local, although it is distributed over the 

 greater part of the British Isles. 



This species occurs in the Northern United States of 

 America.

The fore wings of this rather variable species (Plate 63, Figs. 

 5-7) are yellowish or reddish grey, with a darker basal patch 

 and central band ; a reddish blotch below the tip of the wing is 

 edged with white, and the central band is also outwardly edged 

 with white. Hind wings, whitish, with two lines, and dusky 

 hind marginal border, the latter sometimes inclining to 

 reddish. Occasionally, the fore wings are entirely pale 

 ochreous, and the basal patch and the central band only very 

 slightly darker, but the limiting lines are reddish, and the 

 patch under the tip of the wing is bright orange red. Var. 

 insiilicola^ Stand., from the isles of Scotland, has the fore wings 

 rather narrower, and suffused with purplish brown or deep 

 violet grey ; the hind wings are smoky grey. The female is 

 usually smaller than the male, and often more yellow in colour. 



Eggs, whitish brown, mottled with darker. The early stages 

 are shown on Plate 67, Figs. 2-2b. 



The long caterpillar is pale yellowish brown, with three lines 

 along the back, the central one dark brown, and most distinct 

 at each end ; the others are white, irregularly shaded above
