354 LEPIDOPTERA. 



spots crowded in the basal half of the wings, the outer halves 

 being almost spotless ; one from Mr. Bond's collection has a 

 broad band of coalesced black spots, another a band of elon- 

 gated spots or bars ; and one specimen is almost wholly dark 

 orange-brown, the costa a little more yellow. Mr. J. A. Clarke 

 also has one almost wholly dark brown, and another with a 

 broad black-brown band near the base of the fore wings ; and 

 in Professor Meldola's collection is one richly coloured, but 

 with the usual black spots only indicated in deeper yellow. 

 In a specimen which I took in Surrey many years ago more 

 than one-half the spots are absent from the fore wings and 

 the rest altered in shape, while the hind wiDgs have only a 

 few dark dots. Most of these seem to be mere aberrations, 

 but Mr. W. H. B. Fletcher has pointed out that there seem 

 to be racial variations in the North of Scotland, where, in 

 Sutherland shire, the black blotches are frequently very much 

 enlarged, or else greatly crowded towards the base of the 

 wings. 



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



Larva smooth and without projections ; head rounded, 

 shining green, body longitudinally and alternately striped 

 with green and white ; the dorsal stripe dark green or 

 purplish-brown ; parallel with it on each side are three 

 slender white subdorsal lines, divided by stripes of green, 

 which are in each case darkest at the edge, and the lowest of 

 which includes the spiracles ; these are white, in black 

 ovals ; below them is a broad greenish-white longitudinal 

 stripe ; legs green. 



July and August on wood sage (Teucrium scorodonia), 

 Lamium jpurjpurium, Stachys syJratka, and almost certainly 

 Galcobdolon luteum. 



Pupa very thick in the middle, the tips of the wing-covers 

 considerably raised from the adjoining segments, tapering a 

 little forward, and very considerably behind ; head rather 

 full and prominent, the palpus-covers forming a round button ;
