250 BRITISH LEPIDOPTERA. 



setae on the right and 5 on the left (tubercle i) in each segment ; 

 tubercle ii is represented by a single chitinous button, with pigmented 

 area bearing a single seta, and it would be quite lost among the shagreen 

 hairs if it were not for the fact that it bears a longer hair, the 

 hairs occupying primary tubercular areas being longer than the others ; 

 tubercle iii is represented by a group of 3 setae close together, above, 

 and slightly in front of, the spiracle ; iv and v are rather obscured, 

 there are two little groups of setae, 3 in each (sometimes 3 . in one 

 and 2 in the other) rather conspicuous beneath spiracles which 

 appear to represent these tubercles. The whole body is thickly 

 sprinkled with small chitinous cone-shaped black tubercular points, 

 each bearing a short spiny hair (These are referred to above as 

 shagreen tubercles and shagreen hairs respectively). The skin, for 

 a considerable area (compared with the size of the tubercular points) 

 around each point, is dark sepia- or smoky-green, black to the naked 

 eye. Spiracles large, almost level with skin surface, white with a 

 black chitinous rim, placed rather forward on segments (except that on 

 prothorax, where it is, as usual, posteriorly situated). Hairs on 

 head short and numerous ; on body often tapering, but some- 

 times blunt-ended, and apparently slightly notched (but I have not 

 mounted them to make certain) ; the setae arising from the primary 

 tubercles are about twice the length of the others. The 7th and 

 8th abdominal segments are much shorter than the others, and the 

 9th is a mere slip (May 10th, 1900). Third stadium (well-grown): 

 19mm. — 22mm. in length, short, stout, and Sphingid-like in appear- 

 ance, tapering from 2nd abdominal to the small head, does not 

 differ much in general appearance from the 2nd stadium, but is plump- 

 er and of a brighter and more vivid green. Head rather tall, with 

 tendency to squareness, and slopes at an angle of about 45 ; bright 

 green in colour, the cream-coloured subdorsal and lateral bands 

 of thorax continued on head until they meet at base of antennae, 

 between them a dark green band, whilst another borders the lateral 

 and ventral edges, and a third occurs just above the continuation 

 of the subdorsal band, running from crown of head to just 

 inside the antenna ; the area between these last dark stripes and 

 clypeal triangle cream-coloured. A few very small fine hairs occur 

 on the head, but do not form a noticeable feature ; there is but a 

 slight tendency to develop black bases to the head hairs (although 

 this is a conspicuous feature of the body hairs), and, where present, 

 it is most marked on the dark green areas. The dark green stripe 

 at edge of ventral area, which runs beneath the continuation of 

 lateral band, becomes tinged with pink near the antenna, and is 

 continued as a dark pinkish stripe across the mouth. The body 

 is pale whitish-green on dorsal area, deepening to a lovely pellucid 

 apple-green on sides and ventral area ; the black spots surrounding 

 bases of short shagreen body hairs are strongly in evidence, closely 

 crowded together on the ventral and lateral areas, but fading on the 

 upper lateral, and becoming mere black specks on the dorsal, area ; they 

 (the black specks) are also either absent or exceedingly minute on the 

 area of the pale cream stripes. There is a dark green median 

 stripe, almost black, on the prothorax, and quite black where 

 it ascends and descends the stumpy horn on the 8th ab- 

 dominal. The subdorsal stripe on the thoracic segments is 

 faint and poorly marked, but the lateral band on the same segments
