Mr. R. Bunker, of Rochester, who has reared this larva from the egg, states that " the 

 habits of the larva are singular ; before the first moult it is much inclined to wander, and 

 goes looping along after the manner of the Geometers ; after the second moult it becomes 

 sluggish. It is a voracious eater — in short, an accomplished gastronome. Its manner of 

 feeding differs from that of any larva I have had the pleasure of rearing. It rests with its 

 body stretched out at right angles to the edge of the leaf, and eats with its feet fixed on 

 the side of the leaf, and as the food is consumed moves backward, and when the leaf is 

 consumed to the mid-rib, leaves it to try its gormandizing propensities on a fresh one. 

 As the worm, while feeding, rests as above mentioned, the reason of its leaving the 

 leaf half consumed will be ob\dous — it would otherwise have no surface to hold on to." 



Moth is very large, expanding nearly six inches. The palpi, head, thorax, and 

 abdomen, olive-coloured ; fore wings denticulated on hind margin ; pale olive colour, 

 with an indistinct irregular darker streak across the middle, and margined towards the 

 base of the wing with a still paler hue ; a broad, deep olivaceous median band, contain- 

 ing a pale angular discal spot, and darkest at base of wing ; two other bands of same 

 colour but different shades across the wings ; hind wings purplish-red in the middle, 

 with a transverse black spot above inner angle, and a blackish olivaceous patch beneath 

 it. In the male, the wing is olivaceous exteriorly and along terminal border.
