46 NONAGRIA SPARGANII. 



larva, when it was about an inch and a quarter to an 

 inch and a half long, was considerable, though still 

 slender; the stripes stronger, brighter, and fuller 

 green, yet somewhat of a transparent nature, for when 

 folds of skin occurred at the segmental divisions, as 

 they did when the larva was not stretched to its full 

 extent, the stripes on the folds appeared darker, and 

 the pale interspaces paler. 



The full-grown larva when extended was about one 

 and seven-eighths to two inches long, and very slender, 

 with all the legs fairly well developed, very cylindrical 

 and uniform in substance throughout the body ; the 

 head was of a full roundish form, broadest in front, 

 glossy and of a pale brown colour, with still paler 

 papillae, the mouth darker brown and the ocelli black ; 

 the plate on the second segment and that on the anal 

 flap were also pale brown and glossy ; the ground 

 colour of the back and sides was light semi-transparent 

 yellowish-green, that of the belly rather paler; the 

 stripes, of a brighter and deeper green, were situated 

 one on each side of the back and one below on 

 each side close to the spiracles, the width of the 

 stripes being nearly equal to the spaces between them ; 

 the dorsal space was faintly of a deeper greenish, 

 showing more or less the pulsating vessel ; the spiracles, 

 narrowly ovate, were light reddish outlined with black ; 

 the minute tubercular dusky dots were set within the 

 green stripes, and though lightly ringed with the paler 

 ground colour were inconspicuous, the legs furnished 

 with brown hooks. 



When nearly full-fed it became shorter and stouter, 

 growing more and more translucent as the stripes be- 

 came fainter, the dorsal vessel plainly pulsating, and 

 delicate ramifications of the tracheal system appearing 

 through the skin. 



The pupa was about seven-eighths of an inch in 

 length, moderately stout and nearly uniform in sub- 

 stance throughout, being much of a cylindrical shape, 

 though the upper parts of the thorax and short wing-
