XVIL—THE TINEIDAE. 
The expansion of the wings is about 2 inch. The fore-wings 
are elongate with the termen oblique; the basal half is pale 
purplish-grey spotted and speckled with black, especially at its 
edges and on the fold; the apical half is rather bright ochreous- 
yellow; there is a small pale ochreous patch on the dorsum at 
the base; a fine strongly-indented blackish sub-terminal line and 
a pale grey sub-apical patch. The hind-wings are pale ochreous, 
tinged with grey towards the apex and termen. 
The perfect insect appears from October till December, 
and frequents forest. 
Deseribed and figured from a specimen in Mr, Phil- 
pott’s collection. 
BORKHAUSENIA PLAGIATELLA. 
(Tinea plagiatella, Walk., Cat., xxviii, 485; Gelechia contextella, 
ib., xxix., 656; Borkhausenia plagiatella, Meyr., Trans. N.Z. 
Inst., xliii., 64; Borkhausenia crotala, Meyr., ib. xlvii., 213.) 
(Plate LI., fig. 5 @ typical form; 6 pale variety @; 7 dark 
variety 9.) 
This pretty, variegated species is probably common and 
generally distributed throughout the country. 
The expansion of the wings varies from slightly under 3 
inch to slightly under # inch, The fore-wings are white move or 
less clouded with yellow; there are five brownish-grey or black- 
speckled patches on the costa; the first and largest at the base, 
reaching across the fold, the second before the middle, the third 
beyond the middle, the fourth before the apex, emitting a fine 
wavy line which nearly reaches to the tornus, the fifth is situ- 
ated on the cilia at the apex; there is an irregular grey mark on 
the fold and two distinct discal dots at 4 and #%, often centred 
with yellow, or yellowish-brown; a yellowish-brown blotch from 
dise to tornus and two grey blotches on the dorsum. The hind- 
wings are pale grey. 
There is great variation in the extent and depth of 
both the yellow clouding and the grey markings, many of 
which are often obsolete; also in the depth of the colouring 
of the hind-wings. 
A rather large, pale coloured variety of this species is 
common on the lower slopes of Mounts Egmont and Rua- 
pehu, about 4,000 feet above sea-level. Forms heavily- 
suffused with black are also occasionally met with in the 
same localities.. (See Plate LI., figs. 6 and 7.) 
The perfect insect appears from November until Janu- 
ary, and is very common amongst light forest or scrub. 
When resting it stands on all its feet, the fore-legs being 
placed forwards, the intermediate pair outwards, and the 
hind-legs backwards and close to the body. The antennae 
are held backwards in contact with the wings, the wings 
themselves being folded over the body, like the roof of a 
house. 
This species often occurs abundantly in gardens and 
plantations, where it seems to have a great liking for the 
foliage of Pinus insignis and Cupressus macrocarpa. 
The form known as Borkhausena crotala, Meyr., is 
stated to be distinguished by the absence of any yellow 
colouring. 
BORKHAUSENIA HEMIMOCHLA. 
(Oecophora hemimochla, Meyr., Trans. N.Z. Inst., xvi., 38.) 
(Plate XXIX., fig. 32 @.) 
This species has occurred in the North Island at Ham- 
ilton, Cambridge, Napier and Wellington. 
The expansion of the wings is almost % inch. The fore 
wings are pale ochreous-grey thickly strewn with slightly darker 
greyish scales; there is an ill-defined longitudinal white streak 
below the costa, extending from near base to apex, and a narrow 
incomplete whitish sub-terminal line; an oblique blackish-brown 
mark on dorsum at 4; a cluster of blackish-brown scales in disc 
above this; a similar but larger cluster in disc at #; an almost 
clear pale ochreous patch beyond this; there are several scattered 
blackish-brown scales around this patch and towards the apex 
and tornus; the cilia are pale greyish-cchreous with a few scat- 
tered blackish-brown scales. The hind-wings are pale brownish- 
ochreous; the cilia are pale ochreous. 
The perfect insect appears from December till March. 
BORKHAUSENIA SECLUSA. 
(Borkhausenia seclusa, Philp., Trans. N.Z. Inst., liii., 340.) 
(Plate XXIX., fig. 16 @.) 
This obscure-looking, but distinct species has occurred 
on Ben Lomond, Lake Wakatipu and at Lake Luna at ele- 
vations between 1500 and 2000 feet above sea-level. 
The expansion of the wings is 8 inch. The fore-wings are 
dull whitish with ill-defined patches of blackish-grey and pale 
brown scales; the basal area near the costa is strongly clouded 
with blackish-grey; there is a patch of brown scales on the costa 
near the middle, another beyond the middle, another at the apex 
and a much more extensive patch near the tornus; two rather 
well-defined spots composed of black scales are situated in the 
dise and there are two oblique black marks on the dorsum, one 
near the middle and the other before the tornus; a well-marked 
wavy black sub-terminal line extends from the costa at about 
4 and loses itself in the tornal blotch; beyond this line and on 
most of the dorsum there are irregular confluent patches of 
pearly-white scales; the cilia are pale grey, clouded with black- 
ish-grey at the apex and tornus. The hind-wings and cilia are 
greyish-white, speckled with darker towards the apex. 
‘“ Nearest to B. crotala, Meyr., but greyer than that 
species and without any ochreous admixture. The hind- 
wings are also darker.”’ 
The perfect insect appears in December. 
Described and figured from a specimen kindly sup- 
plied by Mr. Philpott. 
BORKHAUSENIA MOROSA. 
(Borkhausenia morosa, Philp., Trans. N.Z. Inst., lvi., 403.) 
This species was taken by Mr. Philpott at Nelson. 
The expansion of the wings is slightly over 4 inch. It is 
considerably darker in colour than either Borkhausenia plagia- 
tella or B. crotala, with less white on the fore-wings. According 
to Mr. Philpott it differs from all other closely allied forms in 
the structure of the terminal appendages of the male. 
The perfect insect appears in December. 
Described from a specimen in Mr. Philpott’s collection.
