46 LEPIDOPTERA. 



anal points, is bordered above by a fine brown line ; next a 

 broad lateral stripe sprinkled closely with brown freckles, and 

 bearing two fine pale lines, the lower of which is whitish 

 throughout the last four segments, and in the hinder part of 

 each of the others ; then the pale puffed spiracular ridge 

 bearing reddish-yellow spiracles ringed with brown ; under 

 the ridge, just beneath each spiracle, is a longitudinal dark 

 brown dash ; undersurface greyish-ochreous with two faint 

 dusky lines; the usual dots wide apart, blackish in colour; 

 the lateral stripe ceases on the front of the thirteenth segment, 

 leaving the anal flap and the long points pale. The difficulty 

 in this description is to speak of these lines and markings 

 with sufficient clearness, and at the same time not to give 

 too strong an idea of them. (Rev. J. Hellins.) 



September till June or July, hybernating when rather 

 small ; on Thymus scrpylhim, Achillea miUefolimii, Potcntilla 

 rcptans, Meclicago lupulina, Veronica scrpyllifolia, Polygonum 

 aviculare, and probably many other herbaceous plants. 

 Hofmann adds Onolrychis, Hippocreins, Cytisus, Hypericum 

 and Tcucrium. It has the same curious habit as the last 

 species, of coiling itself, when alarmed, so as to look like 

 a faded snail shell ; when undisturbed it remains stretched 

 out at full length upon its food-plant ; but when induced to 

 coil it will allow itself to be rolled about like a wheel. 



Pupa long and slender; head, wing-cases and anal segment 

 shining dark brown, rest of the abdomen rather pale red- 

 brown, with spots and transverse streaks of dark brown. 

 (Rev. J. Hellins.) In any small interstice between bits of 

 earth, sticks or stones, in a cocoon of a few threads of 

 siik. 



An exceedingly local species in this country, and usually 

 confined to chalk downs and rough fields on the chalk. In 

 such situations locally plentiful in Kent, at Dover, Deal, 

 Walmer, Folkestone, Rochester, and elsewhere ; also on the 

 chalk hills of Surrey about Reigate and Leatherhead. It is
