XV—THE TORTRICIDAE. 221 
and the termen slightly curved and rather oblique; the colour 
and markings vary as described below. The hind-wings are 
white, with the apex slightly tinged with ochreous, and the 
cilia white. 
According to Mr. Meyrick this species is distinguish- 
able from Catamacta lotinana in the female by the white 
hind-wings and different form, and in the male by the con- 
spicuous dark basal half of the cilia of the fore-wings, the 
usually perceptible basal patch and costal spot, and the 
much smaller size.* 
The variability of this species is extraordinary and the 
difference between the sexes considerable. Some of the 
principal varieties may be briefly deseribed as follows, 
intermediate forms being constantly met with: 
A. MALEs. 
1. Forewings very pale ochreous-grey, costa margined with 
brown to about 4; often a rather large brown spot on 
the costa before the apex; except a pale basal area, the 
rest of the wing is more or less dappled with light 
brown (fig. 17.) 
2. Fore-wings darker with the markings yellowish-brown 
and several conspicuous white spots on the costa (fig. 
16.) 
3. Fore-wings uniform pale brownish-grey, the termen and 
basal half of the costa edged with very dark blackish- 
brown. 
4, Fore-wings uniform cream colour with the basal half of 
the costa edged with brown. 
5. Fore-wings dark blackish-brown with a large, white, tri- 
angular spot on the costa at about 2 and a smaller one 
before the apex. Hind-wings dark grey. This is a very 
dark and distinct variety but every gradation occurs be- 
tween it and the ordinary pale forms (1 and 2) (fig. 
15.) 
B. FEMALES. 
1. The usual type of female has the fore-wings pale straw- 
colour with the veins marked in brown and a number 
of fine transverse markings often roughly dividing the 
wing into a number of squares; there is a rather darker 
basal area; a broad diffused band from 4 of costa to 3 
of dorsum and a large brown patch on the costa, just 
before the apex, the two markings touching in such a 
manner as to leave a pale spot between them on the 
costa (fig. 18.) 
2. Another form like No. 1 but without the veins or fine 
transverse markings in brown (fig. 34.) 
3, This form also resembles No. 1 but has the brown mark- 
ings much brighter and redder (fig. 35). 
4. Fore-wings pale brown, slightly tinged with purplish- 
grey; no markings except several cream-coloured spots 
on the costa. 
The larva is described by Mr. Meyrick as moderately 
stout, cylindrical, slightly tapering at both ends; pale 
ereyish-green, spots concolorous; head pale greyish-ochre- 
ous, lateral margins dark fuscous, mouth spotted with dark 
fuscous; second segment greenish-whitish, with an ochreous- 
tinged dorsal plate; anal segment greenish-whitish, with 
a small ochreous-tinged plate. It feeds in a light silken

tube, amongst spun-together leaves of Genista in garden 
hedges. The pupa is enclosed in a thin, firm, white, silken 
cocoon in the same place. Probably the larva is polypha- 
gous, the food-plant not being native. 
The perfect insect appears from October till April or 
May. It usually frequents forest and is fairly ‘common. 
Mr. Meyrick states that it flies freely over its foodplant 
for a short time about sunset, and also occurs at light. 
CATAMACTA CHRYSOMELA. 
(Catamacta chrysomela, Meyr., Trans. N.Z. Inst., xlvi., 103.) 
(Plate XXVIIL., fig. 24 @.) 
This very bright-looking species has occurred at Kaco, 
north of Auckland. 
The expansion of the wings is 3 inch. The fore-wings are 
very bright, glossy orange-brown with several rows of extremely 
faint purplish spots in the disc, only visible in a strong light. 
The hind-wings are grey, tipped with orange-brown at the apex. 
The perfect insect appears in January, and is found 
amongst manuka (Leptospermum scopariun). 
CATAMACTA TRANSFIXA. 
(Catamacta transfira, Meyr., Trans. N.Z. Insi!, lv., 203.) 
(Plate ion ties da.) 
This species was discovered in Gollan’s Valley, near 
Wellington. 
The expansion of the wings is five-sixteenths of an inch. 
The fore-wings are oblong with apex pointed and somewhat pro- 
duced; pale dull purple with numerous scattered rather large 
yellowish-brown spots; there are two longitudinal whitish streaks 
from the cell below the apex and a central longitudinal streak 
from the base of the wing to the termen, slightly above the mid- 
dle. The hind-wings are dull ochreous, faintly dappled with grey. 
The head and thorax are deep reddish-purple. 
The perfect insect appears in December, and frequents 
forest. - 
CATAMACTA CALLIGYPSA. 
(Catamacta calligypsa, Meyr., Trans. N.Z. Inst., lvi., 415.) 
(Piate LII., fig. 25 9.) 
This species has occurred at Gollan’s Valley and Pae- 
kakariki, near Wellington. 
The expansion of the wings is about 2 inch. The fore-wings 
have the costa strongly arched at the base and the termen sinu- 
ate below apex; snow white with pale bluish blotches, sparsely 
speckled with black or very ddrk brown; a large irregular tri- 
angular blackish marking on dorsum near base; another much 
smaller mark on dorsum near middle; ‘a small bluish blotch in 
disc; a very large, somewhat rectangular, bluish blotch above 
tornus, extending more than half-way to costa; a small triangu- 
lar bluish blotch on costa at 4; another at 3, and a further irre- 
gular mark before apex; the cilia are blackish-grey. The hind- 
wings are very pale ochreous-grey dappled with grey, darker in 
the male. 
The perfect insect appears in December and frequents 
forest.
