it seems to have moulted, and bad become entirely green, 

 with darker green dorsal line ; sub-dorsal line paler than the 

 ground colour; and the spiracular line yellowish; the head 

 brown. When it is one third of an inch long its figure is stout, 

 with the back swelling in a curve, which is highest about the 

 seventh segment ; the head globular, rather narrower than 

 the second segment ; the tail set with two short spines ; the 

 colour grass green, the dorsal line darker green, finely edged 

 with yellowish ; sub-dorsal line yellow, edged with dark 

 green, followed by a finer yellow line ; then the green spira- 

 cular stripe, and a broad, well-defined, whitish-yellow, sub- 

 spiracular stripe ; the spiracles brown. This coloration 

 continued unaltered, as long as any of the larvfe lived, except 

 that in the spring the yellowish lines grew more whitish. 

 Mr. Wailes obtained larvae in 1857, in the same manner, 

 which he described " pale green, with numerous darker green 

 longitudinal lines .shading into the ground colour, and with 

 a well-defined white line along each side in the region of the 

 spiracles." He does not state whether he was able to keep 

 them alive until the spring, but his description sufficiently 

 agrees with that of the Rev J. Hellins. 



In confinement, these various larvae fed on Poa annua, 

 Fcstuca oxina, Aira prcccox, and A. ca'spitosa, but Mr. 

 Buckler's young larvee showed a preference for the mat grass 

 (Nardtis stricta), forcing their way through the gauze of their 

 covering, in order to feed on the tips of this hard and wiry 

 grass ; and in all probability this is its natural food plant. 



July to October, and, after hybernation, probably until 

 May. 



Pupa, little more than three-eighths of an inch in length, 

 rather thick in proportion ; colour of the back of the thorax 

 and the wing cases light green, rather glaucous; abdomen 

 pale drab, or dirty whitish ; there is a dark brown dorsal line 

 on the thorax, and the faintest possible indication of its being 

 continued as a stripe along the abdomen ; the eye- trunk-
