8S LEPIDOPTERA. 



of a house will cause it to emerge from pupa in March, and 

 by a warmer temperature it has been brought out in January. 

 Yet there is no reason to suppose more than a single genera- 

 tion in the year. 



Larva plump, the segments beyond the middle thickened, 

 yet the divisions not deep nor well marked ; head rather re- 

 tractile, rounded in front, pale horn colour, striped down the 

 face with pale brown ; anal segment rather humped but 

 sloping obliquely off; sides wrinkled and a little inflated; 

 colour greenish-white, shining like a piece of porcelain ; down 

 the back is a double row of oblique olive-brown bars, only 

 prevented from meeting by the dorsal vessel, and thus forming 

 incomplete V-marks ; below these on each side is a single row 

 of similar oblique streaks, producing the effect of zigzag 

 markings all over the dorsal portion of the larva, except that 

 the second segment is devoid of them, and longitudinally 

 barred all round with green and white ; legs brownish-white ; 

 prolegs swollen and fatty-looking ; undersurface also shining 

 yellowish-green. 



Or the oblique streaks on each side of the dorsal line united 

 by red-brown streaks into irregular zigzags which almost 

 enclose dorsal diamond shapes ; between these and the lateral 

 streaks is an irregular dark red subdorsal line narrowed and 

 broadened on every segment ; beneath the lateral oblique 

 streaks is an undulating line of pale red and greyish-green, 

 the oblique streaks themselves being darker or tinged with 

 red, and the whole pattern more complex than in the previous 

 variety. Described from examples forwarded from Salop by 

 Mr. F. C. Woodforde. 



June and July, sometimes August, indeed it is as uncertain 

 as the moth, and has been found at the end of April ! On 

 Pyrethrwm inodorum, P. maritimum, Matricaria chamomilla, 

 and Anthcmis cotula, feeding in the bright sunshine, and also 

 at dusk and at night, more especially upon the flowers and 

 seeds. In confinement it devours most ravenously the
