28 THE ENTOMOLOGIST*S RECORD. 



red) sub-spiracular tubercles. The tubercles of 13 are orange 

 (or rather red) like the rest of that segment ; all the other 

 tubercles are black (trapezoidals, supra-spiracular, and post- 

 spiracular, which is still distinct). There is a white spot in 

 front of the posterior-trapezoidal, and a smaller below it, 

 accompanied by two minute satellites, and in front of these a 

 vertical yellow streak, and two behind them. 



In the 5th skin, the larva is when well grown 18 mm. in 

 length, so abundantly marked as to be difficult to describe at 

 all accurately except at somewhat inordinate length, it now 

 has a good deal of the appearance of the adult larva. The tall 

 dorsal hump on 5th has the appearance of an excrescence, 

 rather than a portion of the segment, which in itself is very 

 little larger than the others in size, and in shape resembles 

 them. Thence the segments diminish in size to 11, which is 

 decidedly small, the 12th large, dropping suddenly to 13. 

 Thirteen may still be described as red, except a trace of 

 marbling at posterior margin, 14 black, with dirty white 

 marbling. Head black. On 6-1 1 a broad pale dorsal band, 

 with irregular margin, narrowing between the tubercles, 

 broadening towards the incisions and running outwards in 

 pale marblings. On the middle of segments it is orange 

 yellow, nearly white at the incisions, where a darker central 

 line is most evident. The next area, including the trapezoidal 

 and supra-spiracular tubercles, is black, velvety black in front 

 of trapezoidals, the white spot between the trapezoidals looks 

 raised and polished like a boss of white porcelain, as is also 

 the smaller one between the posterior-trapezoidal and the 

 supra-spiracular ; in front of this is a square, reddish orange 

 patch, and behind it a vertical redder streak and a small spot 

 behind this. The next lower zone, the spiracular region, is 

 fuscous, marbled with dirty or reddish white, forming circles 

 round the spiracles and post-spiracular tubercles. An orange- 

 red line runs below this, including the sub-spiracular tubercles, 

 which are also red, is continuous over 13th segment, and 

 breaks into great red patches on 3 and 4 (and less on 2), 

 separated by marbled fuscous. The lower surface is marbled 

 fuscous. The prolegs have black lateral plates. The tubercles, 

 except the sub-spiracular, a^re black. The dorsal band on 

 3 and 4 is uniformly orange, narrowing to a white line on 2 ; 

 the globular hump of 5th segment carries a few long black 

 hairs and a thick pile of very short black ones covering the 

 globe, and behind it is a tuft of yellowish white hairs arising
