Ferrpay.—Supplementary Description of Chrysophani. 259 
If the Mount Hutt or the Castle Hill form is a distinct species, as it 
possibly may be proved to be, I propose for it the name of Tama, after 
a traditionary Maori chief of that name; and should it be held to be a 
variety only, the name will serve to distinguish it as the mountain form. 
The individuals of the Mount Hutt and Castle Hill form were taken in 
places where Donatia nove-zealandie grows, and secing them hovering about 
and settling upon patches of that plant in a manner indicating the deposit 
of their eggs, I carefully searched the plants, and succeeded in finding one 
larva, of which I made a coloured drawing and wrote out a description. 
The description has unfortunately been mislaid, but the drawing, a copy of 
which accompanies this paper, I have preserved. From the drawing and 
from recollection, I give the following description of the larva :— 
Onisciform ; pubescent; pale green; dorsal line consisting of a dark 
purplish-brown conical spot on the fourth and following segments, the apex 
of each cone pointing towards the head and joining the base of the 
preceding one at the joint of the segment, the cones margined with white ; 
outside and round the white is a margin of dull red; on the side a row of 
pale pinkish oblique stripes, blended on the lower side with dull red; the red 
extending thence to below the spiracles, except on the posterior side of each 
segment, where a green colour intervenes and is blended with the red ; the 
angles formed by the oblique stripes are shaded with a dark colour. On 
the second segment is a dorsal diamond-shaped dark purplish-brown spot, 
with a longitudinal streak of white in its centre. I kept the larva for 
some time, and fed it upon Donatia, hoping to obtain from it a pupa and 
imago, but, after being apparently full-fed and retreating to the root of the 
food-plant, it died, without assuming the pupa state. One egg, which I 
also found at the same time, did not produce a larva. 
Fig. a represents the larva magnified; b, head front segments, also 
magnified; and c, the natural size. 
The larva is so characteristic of the genus that there can be little doubt 
it would have produced a specimen of the Castle Hill form, had it lived 
and passed through its changes to maturity. I know of no other insect to 
which it could belong ; but there is not sufficient evidence to determine the 
fact. j
