346 LEPIDOPTERA. 



In Professor Meldola's collection is a specimen in which 

 the usual darkened portions of the wings are entirely pale 

 fuscous ; Mr. S. J. Capper has a pale yellow male, with 

 orange longitudinal stripes, and the Rev. Joseph Greene one 

 of a deeper yellow. Aberrations in the female are not so 

 extreme ; some in the paler form are almost or quite devoid 

 of the small perpendicular streaks, while those of the banded 

 form vary in the colour of the bands from purple-brown to 

 purple-drab. One of Mr. Webb's specimens has the central 

 blotch of ground colour of the fore wings of a very warm 

 soft orange ; another is wholly of a pale primrose ; and one 

 in Mr. Capper's collection has the bands of an excessively 

 pale fuscous, yet delicately visible. The Rev. T. W. Daltry 

 tells me that in North Staffordshire, where he does not find 

 the banded forms, the perpendicular streaks and speckles are 

 very dark. 



On the wing at the end of June and in July. 



Larva twig-like, rounded, slightly tapering towards the 

 head ; there is a small transverse hump on the fifth segment, 

 and a large transverse prominence, with four points, on the 

 ninth, the two outer points being the larger; two small 

 dorsal points on the twelfth, and similar but smaller on the 

 tenth and eleventh, while two little points protrude from the 

 anal segment ; head flattened, brown, not shining, having a 

 whitish projection on each side of the mouth. Body ochreous- 

 brown or pale ochreous, sparsely mottled with dark brown, 

 especially on the humped segments ; dorsal line much inter- 

 rupted, dark grey, most apparent on the third and fourth 

 segments ; undersurface paler than the ground colour, but 

 dotted with black, and with two indistinct blackish lines on 

 the segments, most conspicuous before the first pair of pro- 

 legs. (C. Fenn.)
