and with three or four black spots near the apex of the costa. 

 Hind wings smoky white with four black dots in the anterior 

 half and a row of the same along the hind margin; between 

 are two partial transverse lines of dark dusting. Body 

 and legs whitish-brown. 



Variable in the ground colour of the fore wings, from 

 dark tawny-brown to pale yellow-brown. 



On the wing in .June, July, August, September and 

 October, even rarely in December. Most irregular in times 

 of appearance. Usually a few specimens are seen in June, 

 but in 1880 it was abundant in that month ; usually far more 

 common in the autumn, at which time in certain years it 

 appears in multitudes. It is still quite uncertain whether 

 there are two or even three generations in the year, or even 

 whether the latest autumn specimens hybernate and re- 

 ap])ear in June ; but very probably there is only one gene- 

 ration emerging at intervals. 



Larva moderately stout along the middle of the body, and 

 attenuated at both ends ; head flattened, widest near the 

 mouth, which is prominent, pale drab, front margins of the 

 lobes freckled with brown, and a group of similar freckles on 

 each cheek ; mouth and a transverse streak above it light 

 brown ; the ocelli black ; dorsal region opaque, cream colour 

 or very pale yellowish-drab, this colour narrow and faint on 

 the third or fourth segment, widening and strengthening 

 along the middle segments, and narrowing towards the end ; 

 dorsal stripe dark translucent green ; thoracic segments 

 broadly tinged on the back with similar green ; dorsal 

 colouring banded on each side by a very hue Hue of dark 

 translucent green, and this by an opaque whitish line which 

 originates on the second segment; well relieved below by a 

 broad stripe of the darker green or greyish-green ; spiracles 

 creamy-white ; undersurface and legs clear watery-green with 

 also a faint tinge of flesh colour ; on either side of the second 

 segment are two velvety black spots, one in front elongate-
