dark green and the segmental divisions yellow; there are a 
few hairs scattered over the body. 
Latterly the larva of this insect has taken to feed on 
the common broom (Cytisus scoparius) joining up the ter- 
minal shoots and feeding on the small leaves. This new 
habit will enable the species to increase its numbers indefi- 
nitely. It is also causing serious damage to various species 
of introduced pines (Pinus radiata, P. strobus and others) 
by twisting up and feeding on the growing points. 
The perfect insect may be found throughout the 
entire year, but is of course commonest during the summer 
months. The darker varieties are often dislodged from 
the dead fronds of tree-ferns in the depths of the forest, 
but the insect is also abundant in gardens and other culti- 
vated places and frequently enters houses. It is indifferent 
to low temperatures, and is often seen during the coldest 
weather in the depth of winter.

Antennae in ¢@ stout, simple, or very minutely pubescent. 
Palpi long, porrected, clothed with dense rough scales diminish- 
ing to apex, beneath with long rough hairs towards base, in @ 
less developed. Thorax without crest. Fore-wings with veins 7 
and 8 separate, 7 to termen. Hind-wings without cubital pecten, 
3-5 approximated at base, 6 and 7 closely approximated at base 
or short-stalked.

There are eight New Zealand species, all confined to 
the South Island. These are rather large, stoutly built 
insects, of striking appearance, which inhabit the moun- 
tains, and exhibit remarkable differences between the sexes. 
These species, which are closely allied, are very imperfectly 
known at present, and others no doubt remain to be dis- 
covered. Entomologists, working in mountainous country, 
will do well to give these insects their special attention. 
GELOPHAULA TRISULCA. 
(Haimologa trisulca, Meyr., Trans. N.Z. Inst., xlviii., 414.) 
(Plate XXV., fig, 15 @, 16 9.) 
This very striking insect has occurred commonly at 
Arthur’s- Pass. 
The expansion of the wings of the male is 1} inches; of 
the female 12 inches. Very closely allied to Gelophaula aenea, 
from which it differs in the following respects:—The male has 
a very broad longitudinal deep reddish-chocolate-brown band on 
the costa, the extreme costal edge not being margined with grey- 
ish-white; the dorsum is broadly clouded with warm brown, a 
central band of bright ochreous-yellow remaining. The hind- 
wings are dark blackish-brown, paler towards the base. In the 
female the fore-wings are dull ochreous-yellow tinged with grey; 
the veins usually distinctly visible. The hind-wings are whitish- 
ochreous, faintly clouded with grey towards the dorsum. 
The perfect insect appears in January, and is some- 
times common on the mountain side from 3,000 to 4,000 feet 
above the sea-level. The male flies freely in hot sunshine, 
but the female usually remains hidden amongst the rough 
vegetation.

GELOPHAULA AENEA. 
(Teras aened, Butl., Proc. Zool. Soc. Lond., 1877, 402; Harmologa 
aenea, Meyr., Trans. N.Z. Inst., xv., 46.) 
This insect has occurred at Porter’s Pass, Arthur’s 
Pass and Mount Hutt. 
The expansion of the wings of the male is 14 inches, of the 
female 14 inches. The fore-wings are oblong, hardly dilated, in 
male moderately broad, in female narrower, costa moderately 
arched, termen not oblique, in male gently rounded, in female 
sinuate beneath apex; dull greyish-fuscous, irregularly suffused 
in male with golden-ochreous-yellow, in female with light yellow- 
ish-ochreous; in male extreme costal edge whitish, except near 
base, in female costa narrowly white throughout: cilia in male 
ochreous-grey-whitish, basal half suffused with yellowish, in 
female white, base ochreous-tinged. Hind-wings in male deep 
ferruginous-yellow mixed with dark grey, especially posteriorly, 
so as sometimes to form a broad, dark terminal band, and an 
obscure discal spot beyond middle, costa towards middle broadly 
paler, cilia whitish-yellow, at base and on tornus ferruginous- 
yellow; in female dull white, becoming broadly pale yellow pos- 
teriorly, cilia white, at base pale yellow. Conspicuous by its 
large size and distinctly coloured hind-wings. 
The perfect insect appears in January. 
I am unacquainted with this species. The above is 
taken from Mr. Meyrick’s description. 
GELOPHAULA PALLIATA. 
(Harmologa palliata, Philp., Trans. N.Z. Inst., xlvi., 120.) 
(Plate XXV., fiz. 35 @; Plate XLIV., fig. 25 9.) 
This very distinct species was discovered by Messrs. A. 
Hamilton and G. W. Howes on the Old Man Range, Cen- 
tral Otago. It has since been taken by Mr. Philpott on the 
Takitimu mountains, Southland. 
The expansion of the wings of the male is nearly 1 inch, 
of the female { inch. The fore-wings of the male are oblong with 
the termen obliquely-rounded; dark blackish-grey thickly strewn 
with yellowish scales. The hind-wings are very dark bronzy-brown 
with an orange-yellow patch on the costal edge, where covered 
by the fore-wings, and a few greenish scales near the dorsum. 
A form, probably correctly identified as the female of this spe- 
cies, has the fore-wings very pale grey, densely speckled with 
darker grey. The hind-wings are whitish-ochreous, densely spec- 
kled with grey. 
The perfect insect appears from December till Febru- 
ary, and is found on open mountain country at elevations 
of about 3,500 feet above the sea-level. 
Deseribed and figured from specimens kindly given to 
me by Mr. A. Hamilton. 
GELOPHAULA TRITOCHLORA. 
(Harmologa tritochlora, Meyr., Trans. N.Z. Inst., xliv., 120.) 
(Plate XXVII., fig. 3 9.) 
Two female specimens of this rare and interesting 
species have been taken on the high open country around 
Lake Harris beyond the head of Lake Wakatipu. 
The expansion of the wings is slightly over # inch. The 
fore-wings of the female are elongate-oblong with the apex rather 
acute and the termen obliquely-rounded; rather pale ochreous; 
there are two patches of thinly-scattered grey scales in the disc,
