The expansion of the wings is about 4 inch. The fore-wings 
are rather narrow with the termen obliquely rounded; pale 
whitish-ochreous or pale brownish-ochreous; there is a brownish- 
black basal area, a broad curved central band broader on the dov- 
sum and a more or less well-defined darker apical patch. In many 
specimens these bands are extremely faint, except on the costa 
and dorsum, and this is usually the case with those having a 
brownish-ochreous ground colour. The hind-wings vary from 
pale gray to pale greyish-ochreous. 
The larva, which feeds in the dead branches of Fuch- 
sia excorticata, is about three-sixteenths of an inch in length, 
very stout, slightly tapering posteriorly. The head is large 
brownish-green highly polished; the second segment has a 
shining brownish-green dorsal plate; the rest of the body is 
pale green; the prolegs are very short; there is a large 
blackish-green spot on the penultimate segment. It inhabits 
the hardest portions of the wood, generally near the junc- 
tion of branches, where it is much knotted. 
The pupa is enclosed in a slight cocoon usually secreted 
in one of the old burrows made by the larva. 
The perfect insect appears from November till April, 
specimens emerging from the pupa as late as the second 
week in March. It frequents forest, or scrub, and is often 
met with amongst the dead fronds of tree-ferns. It rests 
with the wings closed flat and overlapping. The dark cen- 
tral patch on the dorsum of the fully exposed fore-wing 
combines with the visible portion of the same marking on 
the opposite wing and makes a dark spot in the middle 
of the insect. At the same time the antennae are concealed 
and only the tips of the intermediate tarsi visible. When 
thus resting the entire insect very closely resembles a small 
patch of ordinary grey lichen. 
CNEPHASIA MICROBATHRA. 
(Cnephasia microbathra, Meyr., Trans. N.Z. Inst., xliii., 62.) 
(Plate XXVI., fig. 39 9.) 
_ This distinct, though rather inconspicuous species, was 
discovered by Mr. Philpott at West Plains near Inverear- 
gill. It has also oceurred at Otira, Dunedin, and Orepuki. 
The expansion of the wings is nearly 3 inch. The fore- 
wings are light brown; there is a conspicuous blackish-brown 
basal patch; several dots in the disc; a narrow dark brown patch 
on the costa near the middle, continued obliquely half-way across 
the wings as a faint brownish bar; three small blackish-brown 
spots on the costa before the apex and several on the dorsum near 
the tornus; there are two irregularly-curved series of fainter 
brown spots crossing the wing before the apex. The hind-wings 
are blackish-grey. 
The perfect insect appears from September till Febru- 
ary, and frequents damp forests. It is a rare species. 
Described and figured from a specimen in Mr. Phil- 
pott’s collection. 
CNEPHASIA PATERNA. 
(Cnephasia paterna, Philp., Trans. N.Z. Inst., lvi., 391.) 
(Plate LIL, fig..26 74.) 
This remarkable-looking species was discovered by Mr. 
S. Lindsay, at Little River, near Christchurch, 
XV.—THE TORTRICIDAE. 
The expansion of the wings is nearly { inch. The fore- 
wings, which have the costa almost straight, the apex pointed and 
the termen very oblique, are dull brown, very slightly purplish- 
tinged, with numerous blackish strigulae; there are dark mar- 
gined orange spots on the costa near the base, near the middle, 
and immediately before the apex. The hind-wings are pale brown. 
The antennae are blackish broadly ringed with white with whorls 
of cilia at each joint. 
The perfect insect appears at the end of March. 
Deseribed and figured from a specimen submitted by 
Mr. Philpott. 
Genus 16—OCHETARCHA, Meyr. 
Palpi rather slender, curved, ascending, with appressed 
seales, terminal joint extremely short. Thorax with posterior 
crest. Fore-wings with vein 2 from before 4, 3 from angle, 7 to 
termen. Hind-wings without cubital pecten; 3 and 4 connate, 5 
approximated, 6 and 7 short-stalked. 
Represented by a single species only. 
OCHETARCHA MIRACULOSA. 
(Olindia miraculosa, Meyr., Trans. N.Z. Inst., xlix., 246; lv., 661.) 
(Plate XLV., fig. 9 @; Plate XXV., fig. 33 variety.) 
Two specimens of this very striking insect were taken 
by Stella Hudson at Wainuiomata near Wellington. It has 
also been found in Gollan’s Valley. 
The expansion of the wings is slightly over 1 inch. The 
fore-wings are pale brownish-ochreous shaded with darker brown 
towards the apex and thinly covered with numerous minute 
brownish strigulae; there is a very large heavy deep chocolate- 
brown crescentic marking in the disc, the horns of the crescent, 
which are of unequal thickness, resting on the dorsum dnd its 
outer curved edge almost touching the costa. The hind-wings 
are dark greyish-brown, becoming pale ochreous-brown on the 
costa near the base. 
This species may be variable as another somewhat 
similar form, with two thick brown bars on the dorsum in 
place of the crescentic mark, was taken on the Waitakere 
Ranges near Auckland. (Plate XXV., fig. 33.) 
The perfect insect appears late in December, and fre- 
quents scrubby forest. It is thus referred to by Mr. Mey- 
rick: ‘‘This is a most surprising species, its strikingly con- 
spicuous markings being unlike anything else, whilst its 
generic affinity is equally unexpected. I think, however, 
that it may possibly prove identical with the species figured 
by Felder (without description) as Paedisca mahiana (Reis. 
Nov. pl. exxxvii., 40) from New Zealand, and not otherwise 
known to me, which has a somewhat similar scheme of 
marking, but totally different and in fact reversed colour- 
ing, the dark fascia being represented by a pale area and 
the enclosed semicircular dorsal blotch dark instead of 
light. Such an excessive range of variation cannot be 
-assumed without evidence, and therefore I have been con- 
strained to treat the species as new. Felder’s generic attri- 
bution is of no scientific authority, and the colouring of his 
figure recalls some South American insects, whilst his local- 
ities are sometimes erroneous. Special effort should be 
made to find further examples of this curious insect, which 
may be very local,’’
