94 X.—THE GEOMETRIDAE. 
The expansion of the wings is 1 inch. The fore-wings are 
dull rosy-brown, traversed by numerous obscure blackish trans- 
verse lines, somewhat concentrated towards the middle and form- 
ing an ill-defined median band; the termen is slightly shaded 
with blackish, and the veins are marked with dotted lines. The 
hind-wings are grey, tinged with rosy-brown; there are numerous 
very faint blackish transverse lines and the veins are marked 
with blackish dots. The cilia of all the wings are dark grey. 
The termen of the hind-wings has rounded projections at veins 
3 and 4. 
The larva, which feeds on the leaves and blossoms of 
the common veronica (Veronica salicifolia), during the 
summer and early autumn, is about ? inch in length, much 
flattened with prominent lateral ridges; the head and seg- 
ments 2, 3, and 4 are small, and the posterior segments 
are slightly attenuated; the general colour is dark reddish- 
brown tinged with purple on the ventral surface; there 
is an obscure yellowish lateral line and darker dorsal line. 
The head, legs and prolegs are bright orange-brown. This 
larva rests firmly grasping the foodplant, its body rigidly 
extended like a twig: 
The pupa is enclosed in a very light cocoon of silk 
and refuse, on the surface of the ground. 
The perfect insect appears from November till May, 
and is also oceasionally observed in mid-winter. It is 
attracted by light. 
CHLOROCLYSTIS ACOMPSA. 
(Chloroclystis acompsa, Prout, Trans. N.Z. Inst. lviii., 76; Chloro- 
clystis modesta, Philp. (nec. Warren), Trans. N.Z. Inst., 
XLV LOS) 
(Plate XV., fig. 19 @.) 
This is rather an obscure species which has been found 
on Mount Egmont and Mount Ruapehu in the North Island 
and on Ben Lomond and Bold Peak, Lake Wakatipu, in 
the South Island, at’ altitudes of from 3,000 to 4,000 feet 
above the sea-level. 
The expansion of the wings is about 1 inch. It is very 
like Chloroclystis dryas in almost every respect, apparently dif- 
fering only in its slightly larger size, more acutely produced 
apex of fore-wings, and dark greyish-black colouring. There 
is hardly any trace of the warm pinkish-brown suffusion charac- 
teristic of C. dryads. 
The perfect insect appears from December till Feb- 
ruary. 
Described and figured from Mr. Philpott’s specimens. 
CHLOROCLYSTIS ARISTIAS. 
(Chloroclystis aristias, Meyr., Trans. Ent. Soc. Lond. 1897, 385.) 
(Plate XI., fig. 26 9, 27 @.) 
This beautiful insect was discovered on the Mount 
Arthur Tableland at an elevation of about 4,000 feet. It 
has sinee occurred plentifully on Mount Egmont, at Dun- 
edin and on Ben Lomond, Lake Wakatipu. 
The expansion of the wings is 14 inches. All the wings 
are very pale greenish-grey. The male has three distinct dark 
brownish bands near the base, an irregular broad suffused band 
near the middle, becoming obsolete before it reaches the dorsum, 
a dark patch at the apex, another patch on the termen below 
the apex and another near the tornus. The hind-wings are 
traversed by numerous, very fine, wavy blackish lines, becoming 
darker towards the dorsum. In the female there are three wavy 
reddish-brown bands on the costa of the fore-wings, becoming 
obsolete towards the dorsum, then a wavy yellowish line, followed 
by two rust-red patches. The hind-wings resemble those of the 
male. Both sexes have the veins dotted with black, and the cilia 
of all the wings are grey barred with black. 
The perfect insect appears in December and January, 
and frequents sub-alpine forests. It is attracted by light. 
CHLOROCLYSTIS FURVA. 
(Chloroclystis furva, Philp., xlix., 239.) 
(Plate XI., fig. 34 @.) 
This dark-looking little species was discovered by Mr. 
Philpott on Mount Cleughearn at an altitude of about 
2,300 feet above the sea-level. 
The expansion of the wings is ~ inch. The fore-wings are 
dark grey heavily speckled with dull reddish; the markings are 
very indistinct; there is a wavy dull reddish subterminal band, 
partially bordered by a fine white line on its inner edge near 
the costa. The hind-wings are dark grey with a few whitish 
lines on the dorsum. The cilia of all the wings are greyish- 
ochreous barred with blackish-grey. The veins are dotted in 
black. The ciliations of the antennae in the male are very long. 
The perfect insect appears in January. It flies freely 
around Veronica buaxifolia and other sub-alpine shrubs. 
Described and figured from specimens kindly given 
to me by Mr. Philpott. 
CHLOROCLYSTIS RUBELLA. 
(Chloroclystis rubella, Philp., Trans. N.Z. Inst., xlvii., 193.) 
(Plate XII., fig. 19 4.) 
This large, very dark-looking species was discovered 
by Messrs. Fenwick and Oliver on Bold Peak, at’ the head 
of Lake Wakatipu. It has also occurred on Ben Lomond, 
and on the Lake Harris Saddle in the same district, as 
well as on the Hunter Mountains. 
The expansion of the wings is almost 14 inches. The fore- 
wings are rather broad with the apex rounded and the termen 
very oblique, dark blackish grey strongly flushed with pinkish- 
ochreous; there is a dark basal patch, two distinct black edged 
sub-basal bands; no clear median band; a pale area above the 
tornus; an extensive cloudy shading on the apical and terminal 
area, with a paler somewhat crescentic mark below the costa; 
a bluish-white faint jagged subterminal line; the veins are dotted 
with black, partially ochreous in the disc. The hind-wings are 
pale grey heavily mottled with blackish-grey towards the body. 
The cilia of all the wings are pinkish-grey strongly barred with 
black. The female is considerably paler than the male with the 
veins more distinctly marked in ochreous-brown. 
The perfect insect appears in December and January. 
It is found on the upper edge of the forest, at elevations 
of about 4,000 feet above the sea-level, and is attracted by 
the flowers of Veronica buxifolia. 
CHLOROCLYSTIS ERRATICA. 
(Chloroclystis erratica, Philp., Trans. N.Z. Inst., xlviii., 420.) 
Plate XI., fig. 35 @.) 
This rather obscure species was discovered by Mr. C. 
C. Fenwick on Bold Peak, Lake Wakatipu. It has also
