248 [April, 



and the dark embryonic larva coiled round within is plainly visible, 

 and in a few hours hatches. 



The newly hatched larva is 3 mm. long, stoutish, with shining 

 black head and black velvety body with dark green segmental divisions, 

 and conspicuously marked with a patch of creamy-white on the seventh 

 and eighth segments ; the pale pinkish tubercles, in some instances 

 yellowish, rather bnstly, are in two rows down either side, and in about 

 eight hours turn darn drab, and in a day or so blackish like the third row 

 beneath, except those on the white patch which remain white. 



After the first moult, in three days the length is 8 or 9 mm., the 

 stoutness in proportion ; the head black, and the body velvety-black 

 bearing two orange dots on the front margin of the second segment, 

 the shining, rather pointed, black tubercles having their bases reddish- 

 ochreous, after being for a day or so green ; the white patch as before, 

 but now bearing black tips on the tubercles. 



After the second moult the length by the third day has increased 

 to 14 mm. with increase of stoutness ; the black shining head is 

 marked on the face with a yellow chevron, and with pale yellow upper 

 lip and bases of papillae ; the black velvety body has the w r hite patch 

 yet more conspicuous and encroaching a trifle on the ninth segment ; 

 the front dorsal margin of the second segment is marked with orange- 

 yellow, and minute twin dorsal bright yellow dots are on the third and 

 fourth, and a faint narrow transverse divisional streak of yellowish 

 or greyish between them, other similar short streaks occur on the 

 ninth and tenth ; of the three rows of conical black tubercles on 

 each side of the body, the two top rows have their upper bases half 

 ringed with bright orange colour (excepting those on the white patch 

 which have pale yellow), the lower third row have orange bases like 

 slanting slashes ; the anterior legs are whitish, tipped and spotted 

 above with black, each ventral leg with a white crescentic mark above 

 the foot ; and there is some white on the anal flap. 



After the third moult, in two or three days the length is 22 mm. 

 and the thickness in proportion ; the design now more developed shows 

 the head yellow marked with black, and when protruded the horns 

 coloured orange-red, the ground colour is of the palest greenish-yellow, 

 though it is still white on the seventh and eighth segments, but show- 

 ing only in transverse rings a little wider than the very narrow green- 

 ish-yellow ones round the others, for the middle of each segment is 

 transversely banded with velvety black, but narrower on those two 

 with white ground; the segmental divisions are greyish-black; the 

 black velvety bands are intersected with three lines of the ground-
