'rtj [September, 
which they place their legs. They are not easily perceptible on tlie 
food-plant, since they are the same shade of green, and even their 
bristles have the same colour as the hairs on the leaf-stalk. 
The full-grown larva has a length of 65 — 7 lines. Its body is 
much arched, and so contractile, that the creature can appear 1| lines 
shorter, whereby it naturally becomes more deeply arched. The much 
concealed black head has a whitish transverse streak above the mouth ; 
the dark palpi are whitisli at the base. The ground colour of the body 
is an agreeable pale green ; the deeply-seated, brownish-purple coloured 
dorsal line reaches from the beginning of the mesothorax to the be- 
ginning of the penultimate segment ; the rather flat anal plate is semi- 
oval, and in the middle of each side slightly concave. On each side of 
the body from above obliquely, downwards and posteriorly go faint pale 
stripes, only just perceptible, and in many points of view quite invisible. 
The incisions of the segments are deep above, whereby on each segment 
near the dorsal line an eminence arises, which bears a multitude of 
white bristles of unequal length, almost radiating. Below this wart- 
like eminence is a second less conspicuous, with similar bristles. Both 
eminences have hollows in the middle, which the larva can raise or de- 
press at will. The lateral wart, clothed with longer projecting bristles, 
in which the spiracle is not perceptible, is purple-red, and forms the 
rather broad lateral stripe, which, however, does not reach the head, 
since the prothorax is either altogether green at the sides, or is only 
pale reddish posteriorly. The anal plate is purple-coloured only for 
a narrow space anteriorly at the sides. The belly is pale green, with 
many whitish bristles. The ventral legs are short, pale yellowish, rather 
transparent, with short cylindrical feet, with a darker yellowish circlet of 
hooks ; the pectoral legs are spotted with black anteriorly. 
"When the time of pupation approaches, the larva becomes of a 
paler green, and creeps about restlessly, in order to seek a place for 
spinning. As I once lost the larvae of Lyccena Amyntas at this period 
of their lives, because they could find no place suitable for their change, 
I laid crumpled paper, gauze, dry elm and poplar leaves, and old Arte- 
misia stems, amongst the JSrodium plants. As, however, with the larvae 
which first became restless all this appeared of no avail, I shut up the 
two most bleached and shrunk in a small wooden box, in which both 
gauze and paper lay. Here they changed after five or six days (since 
e entually they merely sat still) to pupse without spinning. The 
others in the flower-pot changed on the earth, nearly free. I had 
almost come to the conclusion that spinning in Medon is altogether
