on the coast of Hants and the Isle of Wight, and generally 

 in the south and south-east the tendency is often to shades of 

 reddish on a white ground, or to a very opaque whiteness, 

 the markings in both cases being often obscured ; on the 

 coast of the Eastern Counties the ground colour is usually 

 whitish, though not of so opaque a quality, or perhaps more 

 of a whitish-drab, and the markings are rarely very strong, 

 usually faint or partially obsolete ; on the north-western 

 coasts more tinged with grey. These forms melt into each 

 other, so that the ground colour varies from pure white 

 through pale reddish, rich reddish, reddish-drab, yellowish- 

 drab, and various shades of pale bi'own to brownish-grey, and 

 the markings to all degrees of distinctness or obliteration — 

 especially the latter. In the collection of the late Mr. Henry 

 Doubleday at the Bethnal Green Museum is a very handsome 

 series of well coloured and well marked specimens, unfortu- 

 nately without locality-labels, but which there is reason to 

 think were obtained near Torquay. In Mr. F. J. Hanbury's 

 collection is a specimen the fore wings of which are of a rich 

 bright light red with the markings and nervures slenderly 

 edged or lined with white ; another with thorax and wings 

 clear smooth white, except faint indications of the three 

 stigmata, and part of the first and second lines ; and a third 

 example of whitish ground colour, but with all the markings 

 clearly shown, and all the interspaces delicately dashed and 

 clouded with grey, reddish, and brown. In the collection of 

 Mr. S. J. Capper is a specimen of a creamy-yellow, with the 

 three stigmata distinctly marked but the transverse lines 

 totally absent. Dr. Mason has a specimen of a greyish-white 

 with a reddish flush, and the stigmata faintly indicated in 

 reddish-brown. It is scarcely possible, in words, to indicate 

 the delicate loveliness of some of these forms. 

 On the wing in June and July. 



Larva elongate, rather flattened, shining, with plates on 

 the second and anal segments ; head rounded and polished.
