L0B0PH0RA HEXAPTERATA. 55 



over with delicate hexagonal reticulations ; the colour 

 at first pale green, afterwards whitish. 



The young larva is at first pale dull white all over, 

 afterwards becoming greenish. 



When full-fed the larva is about three-quarters of 

 an inch long, its figure rather stout, of even bulk, 

 cylindrical, but showing to the eye as if almost 

 squared; this appearance seems to be caused, first, 

 by the absence of a dorsal line, for the pulsating 

 dorsal vessel is scarcely to be seen without a lens, 

 and so the eye catches the subdorsal line as forming 

 the edge of a flat back ; and secondly, by the habitual 

 position of the larva, which, when at rest, contrives 

 to lie perfectly flat on the surface of a leaf, somewhat 

 in the fashion of those species which spin leaves 

 together, though in this case I have never detected 

 any spinning whatever; the lobes of the head are 

 horny, and well defined; the hinder segments taper 

 a little, and there are two short anal points ; the skin 

 is somewhat wrinkled ; the ground colour is pale 

 yellowish-green; the head is dull pale green with 

 small black ocelli, the mouth reddish-brown; the 

 subdorsal line (the only ornamentation) is pale yellow ; 

 below it the side is more yellowish-green in tint than 

 the back ; the spiracles very indistinct, pale yellow ; 

 the belly whitish-green ; the segmental folds yellowish 

 when the larva is at rest, when it is in motion they 

 appear green; the anal points pinkish-white; alto- 

 gether this is a very dull-looking larva, having so 

 little variety of colour. 



When spinning, it makes a neat cocoon, three- 

 eighths of an inch long, and just half as w T ide, com- 

 pactly woven of dark silk, with fine grains of earth, etc., 

 stuck over it. 



The pupa is five-sixteenths of an inch long, cylin- 

 drical, the eyes prominent, the abdomen about one- 

 third of the length and tapering off in a curve, and 

 ending in a bifid spike ; the colour on the thorax and 

 wings very dark greenish, on the abdomen deep red-
