nently in advance ; the segments beyond the fourth are well defined, 

 especially beneath, and the deepest wrinkle across the back of each is 

 farther behind than in many Pif rales, but this is not very deep, another 

 rather less deep is near the beginning, and a much fainter one near 

 the end ; the ventral legs slender, the anal pair extended behind the 

 body. The colour of the head is pale drab, the front margins of the 

 lobes freckled with brown, and a group of similar freckles on each 

 cheek, the mouth and a transverse streak above it light brown, the 

 ocelli black ; the dorsal stripe is dark translucent green, showing at 

 times a still darker pulsating vessel within ; this stripe is less distinct 

 on the thoracic segments as they are broadly tinged on the back with 

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

 the back is of an opaque creamy-whitish, or cream colour, or some- 

 times 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 semi-translucent watery-greenish, 

 sometimes having the faintest possible tinge of flesh colour ; on either 

 side of the second segment are two Hack velvety sjjots, viz. : — one in 

 front, elonqate oval, and one behind it, small and round, reminding one 

 of a printer's stumpy-proportioned note of exclamation ; on the light 

 parts of the back, near the beginning of each segment, a transverse 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 aboiit to spin up amongst its food, it cuts partly out a por- 

 tion 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, eyes 

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

 long; the tip of abdomen with a small pointed projection furnished
