They became more white and opaque when towards hatching, and the black eye 

 spots of the inchided larrse could sometimes be detected. They hatched July 3rd. 

 The newly emerged larvse are colourless or whitish, very transparent, with very 

 black eye spots, and , faintly brown jaw tips ; the hairs are long, as long as the 

 diameter of the body, and directed forwards and backwards, but the disposition of 

 the tubercles could not be ascertained, owing to the uniform colourlessness of the 

 larvae, they seemed to be of the usual pattern, with one bristle each. 



The first moult occurred July 7th. It makes no change in the aspect of the 

 larva, which has, however, a greenish tint from the time it begins feeding, from the 

 intestinal contents. 



The second moult occurred about July 11th, and again produced little change 

 in the appearance of the larva. When about to moult, the eye spots present a 

 curious aspect as black spots on the second segment. The disposition of the 

 tubercles and hairs can now be determined with some difficulty ; the dorsal tu- 

 bercles are placed nearly squarely rather than in the usual trapezoidal manner ; the 

 bristles of the anterior pair are directed forwards and inwards, of the posterior 

 backwards and outwards, and of the lateral, or super spiracular, forwards and 

 downwards ; all looking depressed to the larva instead of standing off perpendicu- 

 larly to the surface. 



The third moult occurred about the 15th, one as late as the 18th July. 



My larvae reached me on July 17th, and were then about a quarter of an inch 

 long, transparent, pale yellow, but the dark green alimentary canal, with the green 

 internal organs generally, gave it a strong green appearance ; head very pale yellow, 

 tinged with pink ; eye spots black, jaws pale brown. 



The fourth moult occurred July 20th. 



By July 28th, a length of about five-eighths of an inch had been attained : 

 slender, and of nearly uniform width ; skin of the same glossy transparent texture 

 as before. The dorsal, sub-dorsal, and lateral tubercles are raised bosses, surrounded 

 by radiating lines or plaits which encroach on the dorsal bosses, but not on the sub- 

 dorsal ; in some respects the tubercles from these plaits remind one of the summit 

 of a Noctua egg ; the hairs of the anterior pair of dorsal tubercles are directed 

 forwards and inwards, of the others outwards and a little backwards ; the tubercles 

 of the third and fourth segments are same as the others, but the second pairs are 

 very small ; the sub-spiracular tubercle is a compound one of some length, and 

 cari'ies two bristles, one directed forwards, and one backwards, both rather down- 

 wards. 



Ground-colour pale yellow, but the very conspicuous dark green alimentary 

 vessel showing through, together with the green internal organs along the sides, 

 still form the prevailing colour of the dorsal area : the dorsal stripe is broadly 

 boi'dered on each side with pale greenish-white ; spiracles black ; head pale yellow, 

 with blackish ocelli, and brown mandibles, as before. 



When about to moult, from abstinence from food, the dark gi-een colouring is 

 lost, and the larva appears almost uniformly bright pale yellow. 



Ou and about July 31st, they were inoultiug for the last time, 

 and on August 5th I described them as follows : — 



Length, five-eighths to three-quarters of an inch, and rather slender; head
