176 SCOPOLA FEKRUGALIS. 



similar green, but beyond them, on either side of the 

 dorsal stripe, the back is of an opaque creamy-whitish 

 or cream-colour, or sometimes a very pale tint of 

 yellowish-drab, commencing narrow and faint on the 

 third or fourth segment, widening and strengthening 

 from thence along the middle segments, and then 

 narrowing gradually to the end ; this is bounded by 

 a very fine line of the darh translucent green, closely 

 followed by a much stouter line of opaque whitish, 

 which originates on the second segment and ends on 

 the thirteenth, well relieved below by a broad stripe 

 of translucent darkish green or greyish-green, the pale 

 tracheal thread showing along its lower edge through 

 the clear glassy skin ; the spiracles of the same pale 

 tint of creamy- white ; the belly and legs are semi- 

 translucent watery greenish, sometimes having the 

 faintest possible tinge of flesh-colour; on either side 

 of the second segment are tivo blade velvety spots, viz. one 

 in front, elongate-oval, and one behind it, small and 

 round, reminding one of a printer's stumpy-propor-

 back, near the beginning of each segment, a trans- 

 verse row of fine green freckles can be seen, and on 

 the anal flap a few black ones ; the tubercular warts 

 are slightly raised, each having its small summit 

 green, bearing an extremely fine hair ; hairs proceed 

 also from the head. 



When about to spin up amongst its food, it cuts 

 partly out a portion of a leaf, and draws it over around 

 itself, much in the fashion before mentioned, and then 

 spins its cocoon as a silken lining, and pupates 

 therein. 



The pupa is about five- sixteenths of an inch in 

 length, of moderate substance in proportion, the head 

 and all its parts well produced, the eyes prominent, the 

 thorax well developed ; the wing-, leg-, and antenna- 

 cases long; the tip of the abdomen with a small 

 pointed projection furnished with two curled-topped 

 spines crossing each other ; four rows of minute warts,
