272 LEPIDOPTERA. 



upper side between the first and second broods, the former 

 being the whiter, the latter more creamy ; also, in the second 

 brood especially, there is often in the markings of the fore 

 wings a tendency to tawny shades and clouding, while the 

 shading of the hind wings varies as already stated. 



On the wing in May and the beginning of June, but 

 sometimes, in very forward seasons, at the end of April \ 

 and as a more or less partial second generation at the end of 

 July, and in August, or even September. 



Larva smooth, short, stout and cylindrical; head small 

 and rounded, whitish-ochreous edged with dark brown ; 

 mouth green ; general colour dark emerald-green ; three 

 dark red dorsal spots, edged on each side with white, one each 

 situated on the fifth, sixth, and seventh segments ; two large 

 yellowish-red lateral spots surround the spiracles on the sixth 

 and seventh segments, and two smaller ones those on the 

 eleventh and twelfth, between the two former is a large 

 dark brown blotch ; spiracles black faintly shaded with 

 reddish-ochreous ; legs and prolegs brownish-pink ; on the 

 ventral surface is a broad yellowish stripe. (C. Fenn.) 



Some larva?, figured and described by Mr. Buckler, had on 

 the anterior part of each of the sixth, seventh, eighth, 

 eleventh, and twelfth segments a bright red elongate spot, 

 bordered on either side by a black, and then a white line ; 

 they had also thread-like subdorsal and spiracular white 

 lines. 



Another variety, described by the late Rev. J. Hellins, 

 has the ground colour above grey-brown ; a broad ochreous- 

 yellow dorsal stripe, widest in the middle of each segment, and 

 contracted at the segmental divisions ; very thin subdorsal 

 and spiracular white lines ; on the front of each of segments 

 four, five, six, and seven are two dorsal white spots, and on 

 each segment ten black dots ; undersurface and sides of the 

 first five segments of the same colour as the back, but for 

 the remainder ochreous-yellow ; the lateral blotches on seg-
