species, which showed an enormous variation in size, venation, and colour- 
pattern, and included not only all the supposed species already described 
from Australia, but also all the known New Zealand forms, о with a 
striking new variety which had previously been sent me fro ew Zealand 
but had remained undescribed. Of this series the doeet varieties 
far were humilis McL. (almost unicolorous brown or fawn) and 
instabilis McL. (with irregular broken fasciae and irrorations). The rarest 
of all, totalling only three specimens out of the whole lot, was the original 
type described ‘by Newman as Drepanepteryz binocula in 1838, which had 
remained undiscovered ever since. This form has a conspicuous circular 
eye-spot (black centre and pale outer ring) covering the fork of Cu, and 
extending down to the fork of 1A, in the g. 
It follows that ie specific name of the met Australian and New Zealand 
species now becomes Drepanacra binocula (Newman), while McLachlan’s 
species," together with those subsequently described by Haret and myself,{ 
must sink to the status of.varieties. Of the two New Zealand species 
described by Hare, D. maori appears to me to be barely distinct from var. 
instabilis McL., while D. humilior is only a small form of var. humilis McL., 
such as occurs on the Dun Mountain, pere in company with larger and 
more typical forms. Such dwarf forms c pen be obtained by restricting

ry light irrorations), or fuscous, with heavier irrorations, tending to 
the 2 instabilis type, but is remarkable in having a large irregular pale patel 
placed so as to cover the upper portion of the space between the distal and 
middle gradate series, and extending up on to the costa. This gives the 
insect, when at rest, the appearance of a small dead leaf with a big piece 
cut out of it, and ought to be very effective as a protection against birds 
and other enemies. Taken at Opoho Hill, Dunedin, on the 31st December, | 
1919, by myself (this specimen is dark fuscous, and has the anal area 
of forewing very pale); at Nelson, on the 8th December, 1921, by Mr. A 
Philpott (forewing dark fuscous); and at Forest Hill, өбө ‚ on the
