104 [October, 



The full grown larva measures from six-eigMlis to seven-eigliths 

 of au inch in length, tapering at each end, the segments well divided, 

 and beyond the fourth each is sub-divided by a deep transverse wrinkle 

 on the back into two nearly equal portions ; on the belly they are 

 more deeply divided and very plump ; the ventral and anal legs slender, 

 the anal pair extended behind in line with the body : in colour the 

 head is of a pale watery drab, finely dotted on the crown with black, 

 and freckled with brown on the sides of the lobes, and a pair of blackish 

 dots are a little above the mouth ; the second segment has much the 

 same pale ground colour as the head, and is also freckled with light 

 brown on the side, where there is a conspicuous black elongated dot, 

 and on the dorsal region is broadly marked, somewhat triangularly, 

 with rich semi-ti-anslucent full green, which continues from thence aa 

 a broadish dorsal stripe of equal breadth as far as the eleventh seg- 

 ment, from whence it becomes gradually narrower to the thirteenth, 

 having within it a darker pulsating vessel ; this green stripe is bordered 

 on either side by a rather narrower stripe of opaque-whitish, with its 

 outer edge a little ragged and slightly melting into the rich translucent 

 full green of the sides, inclining a little in part to bluish-green, this is 

 again relieved by the sj)iracular stripe of yellowish-white, extending 

 to the anal legs, having throughout its course along each segment a 

 straight lower edge and a concave upper edge, thickening the stripe at 

 each segmental division and thinning it in the middle of a segment, 

 just where each round black spiracle is placed on it ; the belly is of a 

 very pale w^atery tint of greenish, and has the faintest possible paler 

 line a little below the spiracles ; the tubercular warts are of the ground 

 colour on which they occur, each having a small central black dot with 

 a fine hair ; the whole skin very glassy and shining. 



The cocoon is more or less of an oval shape, about half-an-inch in 

 length by a quarter in breadth, externally covered with fine grains of 

 sand or of earth, and internally lined smoothly with greyish-white 

 silk, very tough in texture. The pupa measures three-eighths of an 

 inch in length, is moderately slender and quite of the usual pyralideous 

 form, the thorax being slightly keeled, the spiracles on the fixed rings 

 of the abdomen rather prominent and larger than those on the flexible 

 rings, the wing covers long, the leg and antenna eases longer still, ex- 

 tending a little free beyond them, the bluntish tip of the tapering 

 abdomen has a more pointed dorsal prolongation, furnished with two 

 very minute converging bristles ; its colour is ochreous-browu and 

 rather shining.
