122 BRITISH LEPIDOPTERA. 



green. Third instar (?) (Moulted on 22nd) : Of a lively green 

 colour ; the first eye-spot yellow, with a black border below, 

 the second one smaller, white with a black border ; the head 

 green ; the caudal horn purple, green beneath at its base ; 

 under a lens the larva is seen to be stippled with fine white points. 

 Fourth instar (J) (Moulted on 30th) : Retained the same coloration; 

 the head green with two V-shaped stripes of a light brown colour ; 

 the eye-spot of the 4th segment somewhat oval, with green stippled 

 centre, surrounded by two rings, the outer one dark bluish-green, 

 the inner light yellow; the second eye-spot yellow, surrounded by bluish- 

 green. The lateral (subdorsal) stripes bluish, but dark greenish above, 

 with the lower half white ; the oblique lateral stripes faint whitish ; 

 the caudal horn shorter, purple in colour, the stigmata white. The 

 next moult was not observed, but the fullgrown larva was as figured 

 in vol. vii. The fullgrown larva of this species is figured by Buckler 

 (Larvae, 6°^., ii., pi. xxv., fig. 2). The drawing was made on 

 November 8th, 1865, from a larva found at Newmarket and fed 

 on vine leaves. It is of a dark sepia-brown colour, with a pale 

 greyish-yellow subdorsal line continued from the prothorax to the 

 base of the caudal horn, broad from the prothorax to 2nd abdo- 

 minal, narrower to the base of horn, and then turning down at 

 the base of the horn to the anal segment as a wide yellowish 

 patch. The spiracles small and white, ringed with black, with 

 a small red supraspiracular spot above each on the 2nd, 3rd, 4th, 

 5th, 6th, 7th and 8th abdominal segments. The head is of the 

 same brown hue as the body. The three thoracic segments are 

 striped longitudinally with two broad, pale, greyish-brown stripes (1) 

 subdorsal (2) just above the legs. There is a large ocellated spot 

 with a large black centre and pale ochreous margin placed above 

 the spiracle on the 1st abdominal segment, and a second smaller 

 unicolorous pale ochreous spot, with a black margin above the 

 red supraspiracular dot of the 2nd abdominal segment. These two 

 ocellated spots are in the subdorsal line. The abdominal segments 

 are divided into 8 subsegments. The caudal horn is moderately short 

 but straight, almost erect and pointed. The terminal segments- slope 

 very rapidly from the base of the caudal horn to the anal extremity. 

 Bartel describes (Pal. Gross-Schmett., ii., p. 105) the fullgrown larva as 

 " measuring 8omm.-9omm. ; very variable, occurring in both brown 

 and green forms, usually, however, glossy blackish-brown ; on each 

 side of segments 4 and 5 stand two circular black ocellated spots, 

 margined with yellowish-white or dark green, and with white centre. 

 Instead of the white pupil, which is placed somewhat sideways, 

 there may occur from three to seven whitish-yellow dots in the middle. 

 The small eye-spot behind the first spot may be either distinct or 

 wanting. It is sometimes also replaced by an unicolorous yellow 

 spot, somewhat lighter margined. Above the legs runs a lighter, 

 often yellowish, longitudinal, lateral stripe, interrupted at the segmental 

 incisions, at the upper margin of which stand the yellowish or 

 yellowish-white spiracles, which are enclosed by black. Somewhat 

 lower than the two eye-spots appears, extending from segments 6-1 1, 

 a light brown or whitish-yellow stripe, which is continued on the 

 straight and erect horn. The dorsum is covered with fine black 

 longitudinal streaks. On the venter fine white dots are interspersed
