In appearance the caterpillar is rather slug-like, being very " deep '* 

 for its length, with the head small. 



The few taken showed considerable variation, some appearing mainly- 

 green, others almost red. The sides were dull green, ornamented with 

 oblique stripes, which varied in the different specimens from dark brick- 

 red to pink. The hairs showed prominently, being long and numerous. 



Pupa. — The pupa was about 6 mm. in length, and stout for its length. 

 The head and thorax were pale green, the abdominal segments brick-red. 

 A double pink line dorsally. According to my observations, no trace of 

 the wing-markings showed through before emergence. 



Chrysophanus sallustius. 



Although common throughout the South Island, this butterfly does 

 not appear to be as variable here as in the North Island. The first 

 specimens are in flight here early in November, the last at the end of 

 April. 



When collecting near the Upper Hutt with Mr. H. Simmonds he took 

 a single larva of this species when beating Coprosma for Coleoptera, and 

 this larva he kindly handed over to me. It was about 12 mm. long, slug- 

 like, bright green, with a crimson streak down the back. The caterpillar

pupated in a half-curled leaf almost immediately. The pupa was pale 

 green with a paler line down the back, and was 10 mm. in length, and 

 stout for its length. 



Argyrophenga antipodum. 



This butterfly seems to be confined to the South Island, frequenting 

 only the tussock country. Mr. Hudson, in his " New Zealand Moths and 

 Butterflies," gives a description of the larva and pupa. 



In February, 1911, when collecting near Fairlie, I was fortunate enough 

 to secure a single fully fed larva of this species. It remained in the 

 collecting-box for three days before I had time to further examine it, 

 and I then found that in the interval it had changed to the chrysalis. 

 Eight days later the butterfly emerged. The caterpillar, in shape, colour- 

 ing, and markings, closely resembled the chrysalis. 



Pupa. — Length, just f in., but, being late in the season, this specimen 

 was probably undersized ; broad for its length ; two horns tussock-colour,

edged with white, projected from the head, and a similar horn from the 

 tail. A white line from front of head along thorax, then splitting into
