petioles had been eaten away by the larva. This pupa was of a greenish-yellow- 
brown colour, just the tint of the faded sundew leaves, and it looked rather 
like a grass seed which had fallen on to the plant and stuck to the gum; it 
may be added that ripe grass seeds are often so found. 
“Tn confinement the larva exhibits a certain preference for suspension 
from the flower-stalk of its foodplant, whose colour is of a reddish green. 
Even when the stem is growing at an angle, its double set of cremastral hooks 
enables the pupa to keep its ventral surface closely appressed to the lower 
side of the stem, so that it is not suspended freely. It seems possible that 
this pupa possesses a certain amount of colour adaptability, those pup 
attached to the reddish flower-stems having usually an increased red suffusion 
in comparison with those attached to glass or white paper. 
“When on an approximately horizontal surface, the pupa is usually 
found dorsum uppermost ; otherwise it invariably suspends itself head down- 
wards and with the ventral surface appressed to its support. 
“Tn the case of a pupa in a horizontal position the cast larval skin is 
sometimes seen lying near it, but quite free and shrivelled up. The suspended 
pupa always gets rid of the larval skin entirely. This habit is the exact 
opposite of that found in Trichoptilus oxydactylus [Buckleria defectalis], whose 
discarded larval skin is not shrivelled up, but is stretched out along the stem 
just above the pupa. 
“When first formed the pupa is of a light apple-green cclour, the wing- 
covers and appendages of a darker green, and a narrow darker medio-dorsal 
stripe. On either side of this last is a series of eight red tubercles, each bearing 
two black spines, both pointing longitudinally in opposite directions ; on 
about the eighth somite, however, the foremost of these two spines becomes 
obsolescent and quite disappears before the anal extremity is reached. The 
cremaster consists of two portions approximately equal to one another, one 
in the centre of the ventral surface of the twelfth somite, the other at the 
anal extremity. 
‘In some cases the newly-formed pupa is wholly suffused with a delicate 
pink flush, which almost becomes a dull red in some specimens. 
“ After a couple of days the bright green begins to fade and ultimately 
becomes a dull uniform pale yellowish-brown, by which time the eyes and 
antenne are clearly marked in black. 
“The pupa is formed about thirty hours after the larva has suspended 
itself, and the moth emerges after about nine or ten days in the pupal state. 
“The moth always emerges in the morning, usually at about
