segment, the lobes rounded ; skin soft and smooth. Ground-colour rich dart green, 

 more or less (in different specimens) dusted with yellowish-brown, some, indeed, 

 being entirely yellowish-brown ; head pale brown, the ocelli, mandibles, and some 

 marks near the top of each lobe, darker ; a line, bluish on the posterior segments 

 (paler in the brown larvse), and white on the anterior segments, edged on each side 

 with a smoky line, forms the dorsal stripe ; sub-dorsal lines waved, of the same 

 colour, but less distinct, as is also a straighter line above the spiracles ; the broad 

 spiracular stripe yellowish-white, intersected throughout by a narrow green line. 

 Ventral area, legs and prolegs, uniformly dingy greenish, or yellowish-brown, in 

 accordance with the prevailing colour of the dorsal area. 



I described them again on November 2nd, when they seemed to 

 be hibernating, though even then they evidently fed during mild 

 evenings. 



Length, about three-quarters of an inch, and moderately stout in proportion ; 

 head glossy, with the lobes rounded, a very little narrower than the second segment ; 

 body cylindrical, and of almost uniform width ; skin smooth, and the segmental 

 divisions distinctly defined. Q-round-eolour reddish-brown, marked with smoke 

 colour J head yellowish-brown, with dark mandibles; dorsal line yellowish-white, 

 finely edged with smoke colour, and on it, at the segmental divisions, a smoke- 

 coloured spot ; sub-dorsal lines of the same pale colour, but less distinct, also edged 

 with smoke colour ; a broad pink stripe extends along the spiracular region ; spiracles 

 oblong, black, those on the 12th segment enclosing a pale spot. Ventral surface, 

 legs and prolegs, brownish-pink. 



At the end of May, some of the larvae appeared to be full-grown, 

 and on the 29th I described them as follows : — 



Length, about one and quarter inches, and proportionately stout ; head glossy, 

 with the lobes rounded, a little narrower than the second, and still narrower 

 than the third segment ; body obese and cylindrical, tapering a little towards the 

 head, and somewhat abruptly at the anal extremity ; skin soft and smooth, but 

 when the larva is crawling, the segments are considerably puckered, and that, 

 together with the distinct segmental divisons, gives to it a wrinkled appearance. 

 Ground-colour of the dorsal area ochreous-yellow, thickly freckled with smoke- 

 coloured and purple dots, and on the anterior segments strongly suffused with 

 purple ; head and corselet brown, the former thickly dotted with paler spots ; the 

 straight pale ochreous medio-dorsal line, extending (as do also the sub-dorsal lines) 

 right through the cors«let, clear and distinct ; and at each division of the segments, 

 on this line, is a large conspicuous smoky mark ; sub-dorsal lines waved and less 

 conspicuous, also ochreous ; spiracles large and distinct, black, with pale centre and 

 edging ; below the spiracles and throughout the ventral area the ground-colour is 

 also ochreous, thickly freckled, and anteriorly strongly suffused with purple, but, 

 being without the admixture of smoke colour, is paler than the dorsal area. 



The first larva went down on the 4th, and the last on the 16th of 

 June ; the moths emerged during the early part of July, most of 

 them during my absence from home.
