262 LEPIVOPTERA. 



the markings a darker shade of the same ; basal blotch 

 represented only by its margin — a broad baud sharply 

 angulated in the middle ; central band narrow, placed far 

 back, several times angulated and almost broken : along the 

 hind margin is a series of dark brown dots ; cilia grey. 

 Hind wings ample, smokj^ brown, cilia paler. Female 

 rather larger, stouter, and the wings a little broader, varying 

 in colour from white to grey and grey-brnwii and the 

 markings distinctly black-brown. 



Underside of fore wings blackish-brown with a paler 

 edging, of hind wings white. 



Variable in size and in the shade of ground-colour in both 

 sexes. A permanent local variety found in chalky portions 

 of the coast of Kent has an extraordinary tendency toward 

 chalky colouring, sometimes with the usual markings, but 

 less distinct, in other cases creamy-white or chalky -white, 

 without markings. On the other hand the limestone districts 

 of the west coast furnish specimens of rather large size and 

 great richness of markings, especially in the female. 



On the wing from -June till August. 



L.\RVA sluggish, stout, tapering to each extremity ; pale 

 greenish-grey, yellowish beneath, semi-transparent : I'aised 

 dots small, black ; head and both plates yellowish-brown. 



June; on Chrysanthemum Itiicanthemvni, Apargia hisjnda, 

 Hypochccris radicatn, and other composite flowers, drawing 

 together the ray-florets of the blossoms, and bending them 

 over so as to conceal itself, then eating out the disk-florets 

 and immature seeds beneath ; also upon the young shoots oF 

 Tcucrium scorodonia and Scnccio s/jvaliditi:, drawing together 

 the terminal leaves and eating out the heart. 



Pdpa blackish-brown, spun up anywhere else than in the 

 lai'val habitation. The larva possesses in an inordinate 

 degree the instinct of escape from confinement when full 

 fed and desirous of spinning up. After numbers had de-
