140 Mr. G. I’. Mathew’s life-histories of 
being devoured by small red ants, which appear to 
attack them when they are on the point of changing, 
and before the tissues have had time to harden. 
The newly-laid egg, viewed through a lens, is perfectly 
globular, smooth, shining, and pale straw-yellow. In 
the course of twenty-four hours it turns to a pale 
yellowish green, and a few hours before it hatches 
the black head of the young larva becomes plainly 
visible. 
The young larva is pale straw-yellow, with a few short, 
scattered brown hairs; head black and shining, with 
minute rudimentary spines upon the crown. The anal 
processes are scarcely visible’ After its first change it 
becomes pale green with a darker dorsal stripe, pale 
yellowish green subdorsal and spiracular lines, and a 
few bristly hairs upon the head and each segment; head 
black and shining, with the spines upon the crown 
slightly more developed. 
After the second change it is pale yellowish green, 
with dorsal, subdorsal, and spiracular lines brighter, 
and anal processes more conspicuous ; crown, and sides 
of face black; spines on crown well developed, black ; 
other portion of head covered with short, black, bristly 
hairs ; just above the mouth an oval, and on each side 
of the face, a linear-shaped, green blotch. 
After the third change the larva becomes altogether a 
brighter green, the head the same; spines on crown 
reddish brown, forming a dark line on each side of the 
face to the mouth; head, spines, and anal processes 
clothed with fine whitish hairs; hairs on body replaced 
by raised yellowish dots. The full-grown larva is 
elongate and subcylindrical with the second segment 
very narrow, and the anal segment produced into two 
processes terminating in sharp points; head very large 
and conspicuous, apple-green, and furnished with two 
carmine, rigid, spines on the crown, the carmine 
changing to black from the base of the spine to near 
the mouth on each side of the face, and bordered pos- 
teriorly by a narrow white stripe; whole of the upper 
surface bright apple-green, sometimes inclining to 
golden-green, irrorated with raised yellow dots, which, 
seen through a lens, emit short whitish airs, and give 
the larva a somewhat roughened appearance; between 
the subdorsal stripe and spiracles a stripe of darker
