102 [October, 



after feeding a little its dark green colour becomes fresher, and the 

 outer margins of the dorsal tubercles more conspicuously yellowish- 

 green. 



Immediately after the next moult it seems to be thickly enveloped 

 with radiating bristles of a tender bluish-green, mixed with whitish as 

 it sits to recover strength, and as soon as it recommences feeding its 

 growth quickly brings the length of 10mm. and a more lively colouring; 

 the bluish-green dorsal tubercles ai'e strikingly defined by a creamy- 

 white subdorsal stripe on which their outer margins encroach a little, 

 a w^idish stripe of dark green follows, contrasting with the lighter green 

 tubercles and skin below. 



After the last moult, full growth being attained, when stretched 

 out the larva measures from 13 to 14mm. in length, the greatest width 

 across the middle of the body 5mm., it tapers a little at either end and 

 is rounded off behind, and also in front when at rest with the first two 

 segments retracted ; the head is extremely small and flattened, the 

 segments are plump and very deeply divided, the second is smooth and 

 glossy, the tubercles are slightly raised, large, occupying nearly the 

 length of a segment, except the lowest just above the feet which are 

 rather smaller, in shape they are roundish ovate, the dorsal pair side 

 by side on each segment are set close iind obliquely together in front, 

 leaving between them a small central arrow-head-like space behind at 

 the division ; the legs are rather short and w^ell under the body, the 

 belly flattened and smooth : in colour the head is black, the antenna! 

 papillae greenish-white tipped with black, the second segment greenish 

 with broad black marking or plate tapering toward the front, the 

 tubercles on the back are of rather bluish light green, the dorsal row 

 of markings black, the white subdorsal marking inclines to creamy- 

 white, sometimes to yellowish-white, this is contrasted strongly below 

 by a broadish stripe of dark green tapering towards the head and a 

 little also to the hinder part of the body ; on the smooth skin between 

 the dorsal tubercles at the beginning of each segment, and of the 

 white subdorsal marking are sprinkled some most minute black dots, 

 only a few are on the white where it is broadest but they arc numerous 

 on the dark green stri2)e following it, the side below is entirely green 

 including the tubercles, and the whole of them are studded thickly 

 with short and fine blackish bristles, the spii'acles black, anterior legs 

 black, the belly and ventral legs green. 



The situation of the cocoons could be detected by very slight 

 elevations on the surface of the deep pot of earth, where, before the 

 larva? had buried themselves, all had been quite level, and when the
