XV—THE TORTRICIDAE. 
brownish-grey. The female is Smaller with the wings narrower; 
there is a large, pale patch at the extreme base of the fore-wings 
converting the basal marking into a broad band and the pale 
central portion of the large costal patch is much more pronounced 
than in the male. 
The perfect insect appears in January. It frequents 
damp grassy places, but seems to be very loeal. 
EPICHORISTA ERIBOLA. 
(Proselena eribola, Meyr., Trans. N.Z. Inst., xxi., 156.) 
(Plate XLV., fig. 13 ¢@.) 
This very dark-looking little insect has oceurred at 
Otira and at Poherua near Greymouth. 
The expansion of the wings is barely 2 inch. The fore-wings 
are rich brown with dull purplish-grey reflections; there is a mot- 
tling of clear bright brown; a wavy, clear brown band from 
about 4 of costa to the dorsum before the tornus and a narrower 
curved band from the costa before the apex, reaching «a little 
more than half across the wing. The hind-wings are deep black- 
ish-brown. 
The perfect insect appears in January, and frequents 
damp forests, sometimes ascending as high as 3,000 feet 
above the sea-level. 
EPICHORISTA ZATROPHANA. 
(Harmologa zatrophana, Meyr., Trans. N.Z. Inst., xv., 46; 
Proselena zgatrophana, ib. xvii., 144.) 
(Plaverexivis ales 6 aes) 
This bright-looking little insect was discovered by Mr. 
Meyrick on Arthur’s Pass in January, 1883, at an elevation 
of about 3,000 feet above the sea-level. It was also taken 
at Christchurch about the same period, but so far as I am 
aware, has not been detected by subsequent collectors. 
The expansion of the wings is about ? inch, The fore-wings 
are oblong with the costa strongly arched, warm yellowish-brown 
clouded with leaden grey on the sub-terminal area; the basal 
patch is yellowish-brown and is followed by an ill-defined silvery 
grey band; there is a broad oblique orange-brown costal bar near 
the middle reaching more than half-way across the wing; beyond 
this are several irregular yellowish-brown blotches with silvery- 
grey lines between them. The hind-wings are bronzy-grey. 
Deseribed and figured from one of the original speci- 
mens kindly given to me by Mr. Meyrick. 
EPICHORISTA EMPHANES. 
(Proselena emphanes, Meyr., Trans. Ent. Soc. Lond. 1901, 571; 
Harmologa achrosta, Meyr., ib. 572; Harmologa epicura, 
Meyr., Trans. N.Z. Inst., xliii., 86; Mpichorista thedtralis, 
Philp., Trans. N.Z. Inst., 1, 128; Hpichorista candida, 
Clarke, ib. lvi., 419.) 
(Plate XXVL, fig. 15 4; fig. 30 9, 31 9 variety.) 
This very variable species has occurred in the North 
Island at Gollan’s Valley and Wainuiomata near Welling- 
ton. In the South Island it has been found on the Dun 
Mountain, Mount Arthur, Castle Hill, Routeburn Valley, 
Lake Wakatipu, and Lake Manapouri, at elevations of from 
about 200 to 5,000 feet above the sea-level 
The expansion of the wings is about 4 inch. The fore-wings 
are rather elongate with the termen almost straight and slightly 
oblique. In the male the ground colour varies from dark brown- 
ish-black to dull yellowish-brown; there are often a few very 
seattered yellow scales becoming more numerous towards the 
termen; sometimes a patch of steely-bluish scales on the disc 
beyond the middle and usually similar but much smaller patches 
between the veins near the termen. The hind-wings are dark 
brown or brownish-black. In the female the fore-wings are 
usually deep reddish-brown irregularly speckled with bright 
ochreous. There is generally a very broad oblique faint silvery- 
purple band from 4% of costa to + of dorsum; a rather narrow 
outwards-curved silvery-white mark on the costa at about 4, fol- 
lowed by a spot beyond the middle of the wing; there are several 
small silvery-white marks near the apex and termen and the cilia 
are reddish-ochreous. The hind-wings and cilia are dark brown- 
ish-grey. 
There is considerable variation in the brillianey of the 
general colouring as well as in the extent and intensity of 
the silvery-white markings. Sometimes the reddish-brown 
ground colour of the fore-wings is replaced by dark grey 
(fig. 31). Generally speaking specimens from the North 
Island have the fore-wings considerably brighter and red- 
der, the hind-wings darker, and the white costal marking 
seems to be often absent. A very striking variety of this 
insect (Hpichorista theatralis, Philp.), from Mount Cleug- 
hearn, Hunter Mountains, is depicted on Plate XLV., fig. 
12. Another striking form (2. candida, Clarke) has the 
whole of the median area of fore-wings greyish-cream- 
colour, traversed by two ochreous-yellow bands. I have a 
similar specimen taken at Gollan’s Valley, near Wellington, 
where forms intermediate between ‘‘ candida’’ and the 
type also occur. 
The perfect insect appears from November till Febru- 
ary. It usually frequents glades in beech forests, often at 
considerable elevations, flying actively in hot sunshine. 
Occasionally it is found above the limit of forest growth 
and my earliest specimens were captured resting on the 
snow on Mount Peel (Nelson), at an altitude of about 5,500 
feet. A smaller and duller form, found by Mr. Philpott 
in this locality, is ranked by him as a distinct species, under 
the name of Epichorista abdita.* 
EPICHORISTA ALLOGAMA. 
(Harmologa allogama, Meyr., Trans. N.Z. Inst., xlvi., 105.) 
(Plate XXVI., fig. 20 @, 21 9.) 
This richly-coloured little species has occurred com- 
monly in my garden at Karori and on the hills on the East- 
ern side of Wellington Harbour. 
The expansion of the wings of the male is about 4 inch; of 
the female nine-sixteenths of an inch. The fore-wings are very 
deep purplish-brown,; there is a small, very bright, reddish-brown 
patch on the costa before the apex and the termen is narrowly 
edged with reddish-brown; a large oblong patch of dull greenish- 
grey scales is situated near the middle of the dorsum. The hind- 
wings are very dark blackish-brown. The female has a very 
large semicircular creamy yellow mark occupying about half of 
the costal edge. , 
A variety oceasionally occurs in which the fore-wings 
are entirely cream-coloured.
