Potentilla fragai'iastrum was still more commonly selected. 

 Mr. Harwood subsequently found larvje also on P. reptans. 



I'UPA thick and stumpy ; the eyes prominent, the wing- 

 cases well developed ; the whole skin rather rough and the 

 middle of the head, the eyes, and the back, set with short, 

 stiff hairs ; the ground colour reddish grey ; wing-cases 

 piukish grey ; abdominal segments tinged with brownish red 

 along the back ; on the centre of the head, on the eyes, and 

 on either side of the thorax above the wing-cases, are some 

 blackish brown marks ; smaller marks down the middle of 

 the thorax ; and transverse rows of spots on the segments of 

 the abdomen, the largest and darkest being next the wing- 

 cases ; hairs brownish red ; anterior spiracles black ; the 

 remainder black ringed, and placed within the largest dai'k 

 blotches. Enclosed in a habitation similar to that of the 

 larva, composed of two or three leaves, but fastened with 

 stouter silk, and the openings protected by a loose pale 

 yellow webbing. (Hellins.) 



A very brisk little butterfly, delighting to rest on the bare 

 ground, and on stones, in the rough places which it frequents ; 

 sitting with wings half erect, or darting oS" with a swiftness 

 which the eye can hardly follow, to attack another of its own 

 species, or of any other, which may fly past ; then, returning 

 to almost the same spot, to dash off again on the faintest 

 provocation. It frequents broad wood paths and open places 

 in and near woods, the slopes and hollows of chalk hills, 

 sometimes in great abundance, old quarries and other shel- 

 tered sunny rough places. On the Continent it is understood 

 to be regularly double-brooded, but here it is very rarely 

 observed otherwise than in a single brood, emerging in May 

 and continuing through part of June. In 1858 the Rev. C. 

 M. Perkins stated that at Wootton-under-Edge, Gloucester- 

 shire, it was of regular occurrence in August. This district 

 is much sheltered by the Cotswold and other hills, and but 

 few similar instances are known. Mr. W. R. Jeffrey states
