XVII—THE TINEIDAE, 
BORKHAUSENIA THALERODES. 
(Borkhausenia thalerodes, Meyr., Trans. N.Z. Inst., xlviii., 416.) 
(Plate LSScvili slay) 
This bright-looking species has occurred on Arthur’s 
Pass at an elevation of about 3,000 feet above the sea-level. 
The expansion of the wings is about 2 inch. The fore-wings 
are bright orange-brown with a rather indefinite oblique whitish 
mark on the dorsum near the tornus reaching the fold. The 
hind-wings are deep brownish-black. 
The perfect insect appears in January, and frequents 
rough herbage on the mountain side. 
BORKHAUSENIA ROBIGINOSA. 
(Cremnogenes robiginosa, Philp., Trans. N.Z. Inst., xlvii., 200.) 
(Plate Xxx iss Ge) 
This insect, which but for its antennae has a deceptive 
resemblance to Borkhausenia basella, was discovered by Mr. 
Philpott on Longwood Range near Orepuki at an elevation 
of about 2,700 feet. It has also occurred on the Hunter 
Mountains. 
The expansion of the wings is about ? inch. The fore-wings 
are blackish-grey, very densely sprinkled with reddish-brown 
scales; there is a small orange-brown patch near the base and a 
much larger and paler patch near the middle of the dorsum, 
edged with whitish towards the disc. The hind-wings are grey. 
The antennae have long cilia arranged in whorls, 
The perfect insect appears-in December and January, 
and frequents sub-alpine serub, composed of Veronica and 
Cassinia, at elevations between 2,500 and 3,500 feet above 
the sea-level.

pott’s collection. 
BORKHAUSENIA NYCTERIS. 
(Oecophora nycteris, Meyr., Trans. N.Z. Inst., xxii., 219; Bork- 
hausenia nycteris, ib., xliii., 63.) 
(Plate XXX, fig: 34 @,° 35 9%) 
This very dark-looking species has occurred at Well- 
ington, Otira River, Wyndham, Riverton and Invereargill. 
The expansion of the wings varies from about 4 inch to 
slightly over 2 inch. The fore-wings of the male are very dark 
bronzy-brown,; there are three rather indistinct black discal 
dots; the first on the fold, the second before the middle and the 
third beyond the middle. The hind-wings are very dark grey. 
The female resembles a very dark specimen of B. plagiatella, 
except that the basal portions of the fore-wings are clouded with 
grey, and the central portions with rich yellowish-brown. The 
hind-wings are rather dark grey. In both sexes the second joint 
of the palpi is clothed with peculiar erect projecting scales and 
this character separates the species from any of the other mem- 
bers of the genus at present known. 
There is considerable variation in the size of the male, 
specimens from the North Island being smaller and paler 
than those from the South Island.* The female varies in 
colour, some specimens being almost entirely brown like 
the male, and in these the paler variegated colouring is 
confined to the apical extremities of the fore-wings. 

*Tt seems possible that the North Island form may ulti- 
mately prove to be a distinct species. 
The perfect insect appears from October till January, 
and frequents open forests and serub, where it is some- 
times fairly common. Mr. Philpott informs me that in 
the Invercargill district it is found almost exclusively 
amongst manuka (Leptospermum) and is locally very 
abundant. He also states that specimens from the extreme 
south frequently show traces of a white sub-terminal line, 
dorsal streak and tornal band. 
BORKHAUSENIA HOMODOXA. 
(Borkhausenia homodoxda, Meyr., Trans. N.Z. Inst., xvi., 43.) 
(Plate XLVILI., fig. 14 ¢.) 
This very dull-looking, but quite distinct species, is 
common on the lower slopes of Mount Aurum, near Skip- 
pers, Lake Wakatipu. It has also been found on Ben 
Lomond. 
The expansion of the wings is nearly 2inch. The fore-wings 
are very pale greyish-ochreous with a few scattered ochreous- 
brown scales in the disc; there is a very narrow triangular grey 
streak along the costa from. the base to about 4 heavily speckled 
with blackish-grey scales. The hind-wings are grey. The head, 
thorax and anterior legs are grey, heavily speckled with black- 
ish-grey scales. 
The perfect insect appears from November till Janu- 
ary, and frequents open grassy country at an altitude of 
about 35,000 feet. 
BORKHAUSENIA GRISEHATA. 
(Oecophora griseatad, Butl. Proc. Zool. Sec. Lond. 1877, 405.) 
Wings and body above shining grey; primaries irrorated 
with brown, crossed by two widely separated indistinct oblique 
brown lines, the inner one angulated at the median nervure, the 
outer one, which is discal, deeply excavated in the middle; a 
spot of the same colour at the end of the cell; secondaries with 
a feeble brassy tinge: primaries below shining brown, fringe 
grey; secondaries sordid white, speckled with brown; body below 
pale brown; legs white internally. Expanse of wings 7 lines. 
I am unacquainted with this species.

BORKHAUSENIA ANCOGRAMMA. 
(Borkhausenia ancogranma, Meyr., Trans. N.Z. Inst., li., 352.) 
(Plate XLVIL., fig. 6 9.) 
This rather bright-looking little species has occurred 
at Porirua, near Wellington. 
The expansion of the wings is slightly over 4 inch. The 
fore-wings are pale brownish-ochreous with dark brown mark- 
ings; there are two small dark brown marks near the base; a 
large patch placed obliquely on the middle of the fold; two con- 
spicuous discal spots, the first round; the second somewhat cres- 
centic; there are two faint brown patches on the costa and a 
cloudy patch on the termen; the whole wing is more or less 
strewn with scattered brownish scales except on a small dorsal 
area near the base; the cilia are pale brownish-ochreous. The 
hind-wings are pale greyish-ochreous; the cilia pale ochreous 
tinged with grey. 
The perfect insect appears in February, and frequents 
open glades in scrubby forest.
