posteriorly into a narrow transverse ridge; 11th, 12lh and 

 13tli segments gradually diminishing into a conical mass, at 

 the apex of which are the anal clas}Ders, converted into two 

 cylindrical tubes which are nearly parallel, closely approxi- 

 mate and directed backwards ; they are beset both above and 

 beneath with short stiff bristles, and emit a slender drooping 

 filament from the extremity. Colour of the head pearly gray, 

 tinged with purple ; dorsal area of the body divided from the 

 lateral area by a distinct white stripe, which is absent only 

 from the 8th segment ; this commences on each side on 

 the 2nd segment, at the angles already described, ascends 

 obliquely to the dorsal ridge on the 3rd segment, descends 

 obliquely to the spiracle on the 7th segment, is lost and con- 

 fused on the 8th, reappears on the 9th, and is continued 

 thence to the extremity of the anal flap ; on the upper mar- 

 gin of this white stripe, and immediately adjoining it, is a 

 delicate purple stripe, and within this the dorsal area is 

 white, with a median grass-green stripe, and there is also an 

 oblique grass-green stripe on each side of the 7th, 8th, 9th, 

 lOlh and 11th segments; lateral surface apple-green, adorned 

 with numerous roundish, purple spots, each ocellated with a 

 central white dot and enclosed in a white ring ; in addition 

 to these are other larger and amorphous purple spots, pos- 

 sessing the white margin, but wanting the central dot ; the 

 2nd segment has on each side in front a large purple-brown 

 blotch, margined exteriorly with yellow ; and on each side of 

 the 7th and 8th segments are obscure orange patches ; legs 

 principally purple ; ventral claspers apple-green, with a 

 purple, V-shaped, white-margined mark descending into 

 each ; ventral surface apple-green ; anal claspers or cylin- 

 drical horns nearly white above, with a tendency to purple, 

 and a white ring at the tip. When full-fed the larva spins a 

 glutinous cocoon on the bark of the sallow, often towards the 

 bottom of the stem, and changes to a pupa, in which state it 

 passes the winter, the moth appearing about Midsummer fol- 

 lowing, — Edward Netvmrin. 



Description of ihe Larva oj Dicranura hijida. — The eggs 

 are laid separately on the upper surlace of the leaves of 

 Populus balsamilera, about the 1st of July, and the young 

 larva emerges about the 14lh ; it appears to be full-grown 

 about the 26th : it spins a silky coating near the middle of
