256 BRITISH LEPIDOPTERA. 



eye-spot as in larva i, except that the ist member ot the eye- 

 spot is the larger, in i it is, if anything, rather smaller, the 

 subdorsal line is interrupted by it, the upper margin being about 

 the middle of the spot. The line does not widen or alter, 

 but looks as if it might go straight through unaffected, and had 

 the spot superposed, hiding a portion of it. (3) The third figure 

 is also brown or orange-yellow, but the dark shade of fig. 2 is here 

 very much darker, nearly black, and occupies the whole area dorsal 

 to the subdorsal line (and a little below it as in 2), it also somewhat 

 invades the subdorsal line on the 8th abdominal. Eye-spots the 

 same, two portions equal. The subdorsal line stops at the front 

 of the 1 st abdominal. There is a black dorsal plate on the ist 

 thoracic segment. On all three larvae are white (shagreen ?) dots 

 along the subsegments, confined to the area that is dark in fig. 2, 

 and invading the subdorsal line on abdominal segments 1, 2 and 

 3. In fig. 2, the dark shade with dots is shown as breaking 

 through the subdorsal line in the middle of the 3rd abdominal. 

 The eye-spots are blue with black border and central white pupil. 

 II. Sepp gives {Ned. Insecten, vol. vi., pi. xxi) two figures (of the 

 same larva?) : (4 — 5) The first is a lateral, the other a more dorsal 

 view, both are green, with a yellowish shade on the thorax, the 

 ist and 8th to 10th abdominal segments distinctly darker green, 

 just above the subdorsal line. The white dots are fewer than in 

 Roesel's figures ; the eye-spots are round, divided by a central 

 subsegmental line ; they consist of a black circle, shading through 

 blue into central white, with a yellow line outside. There are 



7 subsegments shown in abdominal segments. The subdorsal line 

 stops at anterior margin of the 2nd abdominal. A good deal of 

 the drawing has been done by the colorist (of the hand-coloured 

 plate) and one does not trust it all too much. (6) Sepp figures 

 another (loc. cit., pi. xxii*): Abdominal segments 2, 3, 4, 5, 6, 7 

 and 8, above the subdorsal line, blackish-green, thorax and ist 

 abdominal greenish-yellow, 8 (below line) 9 and 10 yellow. A few 

 shagreen-dots shown, and the subdorsal line, (not on 1 but) on the 

 2nd, 3rd, 4th, 5th, 6th, 7th abdominal segments, shows as consist- 

 ing of shagreen-dots, closely placed on the subsegmental lines, on 



8 it is a white stripe. Eye-spot with yellow outer line and central 

 division, outer margin undivided. III. Dubois figures (Lep. Belg., i., fig. 

 103?) the only larva he ever took. (7) This is green, with darker 

 shading dorsally, widening to posterior border of segments. The 

 subdorsal line extends to the front margin of ist abdominal, which 

 is coloured as the other abdominal segments, and shows an abrupt 

 transition to the yellow thoracic segments, a bluish shading below 

 line with a little yellow round spiracles ; head green ; horn yellow ; 

 yellow line on anal plate and 8th, 9th and 10th abdominal ; segment 

 otherwise green ; 9-10 subsegments; 3rd thoracic shown with 9 subseg- 

 ments and eye-spot occupies 6 of these (2-7), it is figured as by Roesel 

 but even more double ; no white dots are represented ; head green. 

 This strikes one as a very honest good figure, if not of good 



* Hoffmann (Raupen Gross- Schmett., pi. viii., fig. 3a), seems to be obviously 

 a copy (not bad) of Sepp's pi. xxii. Barrett's {Lep. Brit., ii., pi. 53, fig. lb) is 

 a copy of this copy.
