Fereday. — Supplementary Descnption of Clirysopliani. 259 



If the Mount Hutt or the Castle Hill form is a distinct sj)ecies, 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 disting-uish it as the mountain form. 



The individuals of the Mount Hutt and Castle Hill form were taken in 

 places where Donatia novm-zealandice grows, and seeing them hovering about 

 and settling uj)on 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 

 fi'om recollection, I give the following description of the larva : — 



Onisciform ; i^ubescent ; pale green ; dorsal line consisting of a dark 

 purphsh-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 obhque 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 hved 

 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.
