XVIU—THE 
BORKHAUSENIA SIDEROTA. 
(Cremnogenes siderota, Meyr., Trans. N.Z. Inst., xx., 82.) 
(Plate XXIX., fig. 27.) 
This very rare and local species was discovered by Mr. 
Meyrick on Mt. Arthur at an elevation of about 4,500 feet 
above the sea-level. 
The expansion of the wings is ? inch. The fore-wings are 
dark brownish-grey with rich orange-brown markings more or 
less distinctly margined with metallic silver; there is a yellow 
patch on the dorsum at the base; two pale metallic angulated 
transverse lines at about 4; a dark brown transverse band at 
about 4, containing a very dark spot on the fold; a broad costal 
bar of orange-brown near the middle; a large metdllic-edged 
round spot beyond this, followed by a broad sub-terminal band; 
the dorsum and the cilia are more or less clouded with yellow. 
The hind-wings are dark brown, darker towards the termen. 
The perfect insect appeared in January, and was 
abundant on the flowers of Acitphylla within a limited 
locality. 
Described and figured from a damaged specimen in 
the Fereday collection. 
BORKHAUSENIA HPICHALCA. 
(Cremnogenes epichadica, Meyr., Proc. Linn. Soc. N.S.W., 1885, 
793.) 
(Plate XXXVIII.,-fig. 7 @.) 
This rather dull-coloured but very distinct species has 
occurred on Arthur’s Pass and’ on the mountains around 
Otira at elevations of about 3,000 feet above the sea-level. 
The expansion of the wings is 3 inch. The fore-wings are 
elongate-oval with the termen very obliquely rounded; dark grey- 
ish-ochreous and very glossy, sometimes very slightly tinged with 
reddish; there are no markings. The hind-wings are darker and 
browner than the fore-wings. The antennde are long, stout, with 
long cilia arranged in whorls. 
Varies considerably in the depth of colouring. 
The perfect insect appears in January, frequenting 
rough alpine vegetation, on the edges of serees, on the 
mountain side, between 3,000 and 4,000 feet. 
BORKHAUSENIA APHRONTIS. 
(Cremnogenes aphrontis, Meyr., Trans. N.Z. Inst., xvi., 46.) 
CPlate xoxox VIE ie. 22 a.) 
This rather bright-looking speckled yellow species has 
occurred on Mount Arthur and on Arthur’s Pass at eleva- 
tions of about 4,000 feet above the sea-level. 
The expansion of the wings is 3 inch. The fore-wings are 
elongate-oval with the termen very obliquely rounded, leaden- 
grey densely clothed with deep yellow scales; there are several 
very irregular leaden-grey patches on the basal third, a ring- 
shaped mark in the disc and a sub-terminal line; the usual three 
stigmata are plainly indicated by patches of three or four black 
scales. The-hind-wings are dark brown speckled with blackish. 
The palpi are very long with the middle joint yellow and the 
apical joint black. The antennae are stout black. 
Variable in the extent of the lead-coloured patches 
which in some specimens appear to be almost absent. 

TINEIDAE. 267 
The perfect insect appears in January. It is found 
on open country, amongst rough alpine vegetation, between 
3,000 and 5,000 feet. 
BORKHAUSENIA OXYINA. 
(Cremnogenes oxyina, Meyr., Trans. N.Z. Inst., xvi., 45.) 
(Plate XUVi; fig. 6 9.) 
This rather dull, rusty-looking species was discovered 
by Mr. Meyrick at Lake Wakatipu in December, 1882. 
More recently it has occurred on Ben Lomond and at 
Greenhills, near Invereargill. 
The expansion of the wings is about 4 inch. The fore-wings 
are rather pale dull brown very thickly speckled with deep red 
scales; there are dark brown spots on the fold and in the disc 
beyond the middle and sometimes an indented ochreous-whitish 
streak along the dorsum from the base to #. The hind-wings are 
greyish-brown. 
The perfect insect has been found very commonly 
amongst Nothofagus Solandri at elevations of from 1,000 to 
3,000 feet above the sea-level. At Greenhills Mr. Philpott 
found it abundantly amongst Leptospermum. It is evi- 
dently a very local insect. 
Described and figured from one of the original speci- 
mens kindly given to me by Mr. Meyrick. 
BORKHAUSENIA MONODONTA. 
(Oremnogenes monodonta, Meyr., Trans. N.Z. Inst.; xliii., 75; 
Cremnogenes nigra, Philp., Trans. N.Z. Inst., xlvi. 120.) 
(Plate XXXVIII., fig. 10 @.) 
This rather dull-looking species was discovered on 
Mount Holdsworth by Mr. R. M. Sunley and has since been 
found on Mt. Arthur, Arthur’s Pass and the mountains 
around Lake Wakatipu. 
The expansion of the wings is slightly under 3 inch. The 
fore-wings, which are rather elongate with the apex obtuse and 
the termen very obliquely rounded, are dark brownish-black with 
bronzy reflections; there is a whitish-ochreous elongate mark on 
the fold near the middle of the wing and a cloudy pale ochreous 
band along the dorsum. The hind-wings are dark brownish-black 
with bronzy reflections. The dntennal ciliations, which are very 
conspicuous, are four times the breadth of the stalk and whorled. 
The perfect insect appears in November and Decem- 
ber, frequenting beech* forests, at elevations of from 2,500 
to 3,000 feet above the sea-level. 
BORKHAUSENIA AFFLICTA. 
(Borkhausenia afflicta, Philp., Trans., N.Z. Inst., lvi., 401.) 
This species was discovered by Mr. Philpott on the 
Dun Mountain, near Nelson, at an elevation of about 2,000 
feet above the sea-level. 
Extremely similar to Borkhausenia monodonta, from which 
it is stated to differ in less dilated fore-wings and shorter anten- 
nal ciliations of the male. 
*Nothofagus Solandrt.
