ii6 LEPIDOPTERA. 



the red colour is exchanged for green, except that the 

 transverse lines become reddish-white and the cilia continue 

 red-buff. Of this form a very beautiful specimen was ex- 

 hibited at one of the pleasant little gatherings at Mr. 

 Stainton's house, nearly forty years ago, by Mr. A. H. Jones ; 

 it had been captured at Eltham, by his brother, in June 1861, 

 and is still in his collection. Another is in the collection of 

 the late Mr. F. Bond. A third, reared in 1882 from a larva 

 beaten out of pine, with many more, at Brandon, Suffolk, by 

 the Kev. G. H. Kaynor, is of a soft olive-green with pink 

 lines; and one taken at Aldeburgh, Suffolk, in July 1892, 

 by the Rev. C. T. Cruttwell, is of a soft, delicate pea-green 

 with similar lines. In all these the cilia remain red. This 

 form in various shades of green is not scarce in Switzerland 

 and some parts of Germany. In the collection of Mr. J. E. 

 Robson is a Scotch specimen, dull purple-grey; and other 

 specimens from that country are purple-buif and of inter- 

 mediate shades. 



On the wing in June and July, and casual specimens of 

 an extremely partial second generation have been taken in 

 September, Commonly double-brooded on the Continent. 



Larva smooth, skin shining; of even thickness; on the 

 ninth segment is a pair of rudimentary prolegs useless for 

 walking ; two minute dorsal points, on each segment from 

 the fifth, gradually increase in size to the twelfth ; sides 

 puckered ; undersurface rather flattened ; head rounded, 

 orange-brown marbled with red ; general colour orange-brown 

 — the colour of the sheaths of the young pine leaves — with a 

 series of deep dull red dorsal triangles, the apex of each 

 behind, and bisected by an inconspicuous reddish dorsal line ; 

 subdorsal lines whitish, distinct, most so at the sides of the 

 dorsal triangles ; usual spots minute, tubercular, white, emit- 

 ting very short blackish bristles ; sides broadly shaded with 

 red ; undersurface very conspicuously pale greenish-white, 

 dusted in the middle ; legs orange-brown.
