SPHINGIDjE. 33 



the usually darker portion of the fore wings deeply and 

 broadly black ; the black transverse bands of the hind wings 

 double their usual width and intensely black; the narrow 

 marginal band also clouded with blackish ; the back of the 

 thorax unusually dark, and a broad black stripe down the 

 middle of the abdomen, tapering towards the tail. Two 

 specimens reared by Mr. W. Holland at Reading have the 

 hind wings yellowish white. 

 On the wing in June and July. 



Larva three inches in length ; stout, smooth, segments 

 with slight transverse wrinkles ; incisions of segments 

 compressed ; head rough, with minute depressions ; twelfth 

 segment with a large curved horn pointing backwards. Body 

 bright apple-green, segments five to eleven each with a broad 

 oblique white stripe, edged above with lilac, and continued 

 below in the form of white dots upon each preceding seg- 

 ment ; spiracles dull yellow ; head dull emerald green, each 

 lobe internally margined with a broad brown line ; mouth 

 and tips of legs and prologs brown ; horn yellowish beneath, 

 tip and upper surface black ; anal flap edged with yellowish. 

 (Fenn.) 



When extremely young the larva is green, with minute 

 bristles and yellowish dots, the horn at first bristly and 

 slightly forked, afterwards merely covered with small 

 tubercles. The yellow dots and hairs disappear as it grows, 

 the stripes first appear pale greenish, later yellowish, and 

 the lilac and white colour is not shown until the larva is well 

 advanced in growth. 



Mr. Buckler has figured a magnificent variety of the larva, 

 found at Colchester, in which the body is purplish-red, the 

 stripes white edged with black and shading off to faintly 

 greenish on the back ; head and second segment green above, 

 edged with black.
