262 XVII.—THE 
South Rakaia, Dunedin and Lake Wakatipu in the South 
Island. 
The expansion of the wings is slightly under 4 inch. The 
fore-wings, which are elongate with the termen extremely oblique, 
are pale canary yellow, with very pale grey markings thickly 
speckled with dark grey; there is a rather broad costal edging 
from the base to near the middle; a cloudy spot on the dorsum 
near the base; three broken, ill-defined oblique transverse bands 
at about +, 4 and 3, and a cloudy patch at the apex. The cilia 
are pale yellow mixed with grey. The hind-wings are grey. 
There is considerable variation in the grey transverse 
bands, which are sometimes indistinct or absent, and some- 
times replaced by a general vague speckling. The species 
is, however, quite distinct and easily recognised. 
The perfect insect appears from January to March, 
frequenting beech* forests. It is a rare species. 
BORKHAUSENIA AFFINIS. 
(Borkhausenia affinis, Philp., Trans. N.Z. Inst., lvi., 391.) 
(Plate “L1s fig-"3' 3.) 
This narrow-winged species was discovered by Mr. 
Philpott at Nelson. 
The expansion of the wings is slightly under % inch. The 
fore-wings are very narrow, dull grey, very heavily sprinkled 
with dark brownish-grey scales. Except at the extreme base, 
the area below the fold is bright ochreous; there is an ochreous 
discal dot at about # and the apical area is sprinkled with ochre- 
ous scales. The hind-wings, which have the apex acutely pointed, 
are greyish-brown. 
The perfect insect appears in December. 
Described and figured from a specimen submitted by 
Mr. Philpott. 
BORKHAUSENIA PARATRIMMA. 
(Borkhausenia pardtrimma, Meyr., Trans, N.Z. Inst., xlii., 65; 
xlili., 63.) 
(Plate XXIX., fig. 22.) 
This inconspicuous species was discovered at Inverear- 
eill by Mr. Philpott. 
The expansion of the wings is slightly over % inch. The 
fore-wings, which are rather narrow with the termen very 
obliquely rounded, are reddish-brown strongly tinged with ochre- 
ous and more or less speckled with grey, especially towards the 
margins; there are two very indefinite oblique bands of grey and 
the usual discal dots are obscurely indicated. The hind-wings 
are grey. 
The perfect insect appears in November and Decem- 
ber, but is rarely met with. Mr. Meyrick remarks that this 
is a distinct, though inconspicuous species, which may be 
regarded as an early form of the siderodeta group. 
BORKHAUSENIA SIDERODETA. 
(Oecophora siderodeta, Meyr., Trans. N.Z. Inst., xvi., 43.) 
(Plate XXIX., fig. 9.) 
This active, sun-loving, little species is probably com- 
mon and generally distributed throughout the country. 
The expansion of the wings is about 4 inch. The fore-wings, 
which are rather narrow with the apex pointed and the termen 
TINEIDAE. 
very obliquely rounded, are dull greyish-brown very thickly spec- 
kled with dull ochreous or more rarely reddish-brown, interme- 
diate forms often occurring. The hind-wings are dark greyish- 
brown. 
The perfect insect appears from October till Febru- 
ary, and usually frequents somewhat open situations. It 
often flies in the late afternoon sunshine, when it is ex- 
tremely difficult to see. It is also common in cultivated 
places and is frequently seen resting on fences or tree- 
trunks. Whilst thus engaged the antennae are placed back- 
wards and held divergent; the fore- and intermediate legs © 
exposed but placed backwards; the wings closely wrapped 
around the body, the posterior extremity being consider- 
ably elevated and the head depressed. In this position the 
entire insect closely resembles a minute pointed twig. 
Mr. Philpott points out that specimens from Stewart 
Island are larger than those from any other locality.* 
BORKHAUSENIA MELANAMMA. 
(Borkhausenia melanamma, Meyr., Trans. Ent. Soc. Lond., 1905, 
240; ? B. sabulosa, Philp., Trans. N.Z. Inst., 1., 128; ? B. 
terrena, ib., lvi., 392.) 
(Plate XXIX., fig. 2.) 
This small and inconspicuous species was discovered 
by Mr. J. H. Lewis at Ida Valley, Central Otago. It has 
also occurred on Ben Lomond, Lake Wakatipu. 
The expansion of the wings is } inch. The fore-wings are 
pale grey densely speckled with blackish-grey, the darker colour 
tending to form four indistinct transverse bands. The hind- 
wings are grey. 
The perfect insect appears in December and January. 
It is evidently extremely closely allied to B. siderodeta, 
being similar in form of wing but differing im its grey 
appearance, the absence of ochreous-yellow colouring and 
the paler hind-wings. Both species are somewhat variable 
but appear to be quite distinct. Borkhausenia sabulosa, 
Philp., is stated to resemble B. melanamma, but is smaller 
and more speckled. B. terrena, Philp., is described as hay- 
ing a different contour of fore-wing, with complete absence 
of markings. 
BORKHAUSENIA XANTHOMICTA. 
(Borkhausenia xanthomicta, Meyr., Trans. N.Z. Inst., xlviii., 415.) 
(Plate XXIX., fig. 8 9.) 
This very distinct, brightly-marked species has 
occurred at several localities in the immediate vicinity of 
Wellington, at Queenstown, Lake Wakatipu and at Inver- 
eargill. 
The expansion of the wings is about § inch. The fore-wings 
are widest before the middle, with the apex pointed and the ter- 
men very obliquely rounded; blackish-grey, sometimes speckled 
with whitish; the markings are yellow clouded with orange-red 
towards the disc; there is an elongate patch on the fold near 
the base; three broad oblique bands at 4, 4 and #, sometimes 
touching the costa; the cilia are blackish mixed with orange-red 
and yellow. The hind-wings and cilia are rich brown.
