404 I.I-IPIDOPTEKA. 



we(]<re-shaped streak of darker pink exteuds from behind the 

 legs upwards ; from this each segment to the ninth has, on 

 tlie miihlle of the hack, a broad trilobed iiKirl< of darl< pink 

 connected, in the short intervals, l)y a stout dorsal line of 

 the same colour; on the back of the tentii the pink marking 

 is more rudimentary, and on the three liindermost segments 

 is little more than a dorsal, and imjieriect subdorsal stout 

 line, all merging' together at the anal tip ; along the pale 

 green side is a faint and interrupted pink line, and on it the 

 raised dots are whitish ; elsewhere they are not noticeable, 

 as is the case with the spiracles. 



A second variety has the ground colour very ])ale and 

 slightly glaucous-green, a little strengthened in depth in 

 front ; the dorsal mark on the third and fourth segments is 

 a line of purplish-pink which occurs again on the last four, 

 while on each of the intermediate segments is a jjurplish- 

 pink broad-arrow mark with its point close to the division in 

 front, extending backwards about two-thirds of the segment, 

 the ground colour of the remaining third being rather paler 

 than usual ; these arrow-heads are deepest in colour and 

 rather suffused on the fifth and sixtli segments, and each 

 following one is paler but more distinct by degrees: sub- 

 dorsal line pink, distinct and continuous throughout. 



A third variet}- is of the second generation, and before its 

 last moult of jirecisely the same tint as the young ivy -buds 

 among which it was found, and destitute of markings; but 

 afterwards though the same pale grey -green ground colnur 

 was retained, it became conspicuously marked with dark 

 crimson on the head, more faintly on the second segment 

 where was a dorsal line of the ground colour ; with large 

 crimson blotches on the fourth and iifth segments on which 

 a dorsal line could be seen of a still darker crimson ; part of 

 these Ijlotclies extending to the uudersurface and there 

 uniting on the juncture of the fourth and fifth, and neaily 

 so on that of the fifth and sixth ; while towards the end of 

 the sixth, seventh and eighth segments, on the dorsal portion.
