XVI—THE 
BORKHAUSENIA OPACA. 
(Borkhausenia opaca, Philp., Trans. N.Z. Inst., lvi., 403.) 
(Plate XXTX., fig. 15 @.) 
This species was discovered by Mr. Philpott at Tisbury 
near Invereargill. 
The expansion of the wings is slightly under ~ inch. The 
fore-wings are brownish-ochreous, much paler on the dorsum, 
heavily sprinkled with bright reddish-orange scales in the disc 
and on the fold; there is a conspicuous black spot on the fold 
at about 4; @ broad blackish bar on the tornus and a yery in- 
distinct subterminal line; the cilia are brownish-ochreous mixed 
with yellow and orange-red, with a conspicuous blackish bar 
from the tornal mark. The hind-wings are brownish-grey, with 
very strong bronzy reflections. 
An obscure species, principally characterized by the 
peculiar tornal mark, and heavy sprinkling of orange-red 
scales. 
The perfect insect appears in December. 
Described and figured from Mr. Philpott’s specimen. 
BORKHAUSENIA PHEGOPHYLLA. 
(Occophora phegophylla, Meyr., Trans. N.Z. Inst., xvi., 39.) 
(Plate XXXYVIII., fig. 9.) 
This rather bright-looking species, which is evidently 
very closely allied to Borkhausema basella, has occurred at 
Lake Wakatipu and on the Lake Harris track, Routeburn 
Valley, beyond Lake Wakatipu. 
The expansion of the wings is ~ inch. The fore-wings are 
deep orange-brown darker towards the dorsum, there is a con- 
Spicuous wavy yellowish streak along the dorsum, often edged 
with reddish-orange, and nearly interrupted in the middle by a 
rounded projection of the brown ground colour. The hind-wings 
are grey. 
The perfect insect appears in December, and frequents 
beech forests. Its colouring closely resembles that of a 
dead beech leaf. 
Described and figured from a specimen kindly lent to 
me by Mr. F. S. Oliver: There is some doubt as to the 
correct identification of this form. 
BORKHAUSENIA BASELLA. 
(Incurvaria basella, Walk., Cat. xxviii., 492; Oecophora adenp- 
tella, Walk., Cat. xxix., 698; Borkhausenia basella, Meyr., 
PLANG MIN Zi LOS KOCK Re So) 
(Plate. XXIX., fig. 25 @, 26 9; Frontispiece, fig. 28 
portion of egg-mass.) 
This rather large species has occurred at Kaitoke, Wel- 
lington, the Otira River, Blue Cliff and Invercargill. 
The expansion of the wings is considerably over # inch. 
The fore-wings of the male are unifonm brown with a wavy 
yellow streak along the dorsum. The hind-wings are grey. In 
the female the fore-wings are pale brownish-yellow variegated 
with warm brown; there is a clear yellow wavy streak along the 
dorsum, often broadly bordered with dark brown near the mid- 
dle; there are usually one or two discal dots and a wavy sub- 
terminal line. The hind-wings are grey. 
In some male specimens the fore-wings are greyish- 
brown, in others a warmer brown tinged with yellow. The 
depth of the grey of the hind-wings also varies. In the 

TINEIDAE, 265 
female the extent of the brown mottling on the fore-wings 
is very variable, and in some specimens almost absent. 
The perfect insect, which frequents light forests and 
scrub, appears towards the end of October and is extremely 
abundant during November, but is seldom met with later 
than the first week in December. It becomes very rapidly 
worn and is always difficult to obtain in good condition. 
When disturbed it drops to the ground, where it is very 
hard to find amongst the dead leaves and other refuse. The 
male occasionally flies and its dark colour makes it very 
inconspicuous when on the wing. The female appears to 
be a very sluggish insect. I have taken both sexes in great 
abundance amongst the faded flowers of the wharangi 
(Brachyglottis repanda). Myr. Philpott states it iy a rare 
species in the far south. The eggs of this insect are de- 
posited singly or in masses. They are sub-cylindrical, 
much flattened, often partially collapsed, with rows of 
extremely indistinct hexagonal depressions; dull white with 
faint iridescent reflections. 
BORKHAUSENIA AMICULATA. 
(Borkhausenia anvuiculata, Philp., Trans. N.Z. Inst., lvi., 402.) 
This species, which was discovered by Mr. Philpott at 
the Cobb Valley, Nelson, and has occurred on the Mount 
Arthur Tableland and at Arthur’s Pass, very closely re- 
sembles the male of Borkhausema basella, but the apex of 
the fore-wings is more pointed. Mr. Philpott states that 
there are structural differences in the terminal appendages 
of the male which entitle it to specific rank. In this form 
the differences between the sexes, usually associated with 
B. basella, are absent. 
The perfect insect occurs in December, and is found 
amongst veronicas and other shrubs. 
BORKHAUSENIA POLITIS. 
(Oecophora politis, Meyr., Trans. N.Z. Inst., xx., 81.) 
(Plate XXIX., fig. 24.) 
This species, which is very closely allied to B. basella, 
has oecurred at Wellington and at Dunedin. 
The expansion of the wings is about 3 inch. The fore- 
wings, which are rather broad with the termen oblique and 
almost straight, are pale brown very thickly speckled and clouded 
with darker brown; there is a broad wavy yellow-ochreous streak 
along the dorsum to about #; @ very conspicuous Oblique black 
mark on the fold almost crossing the yellow streak; the two 
other discal dots are faintly indicated; there is a faint wavy 
subterminal line. The hind-wings are brownish-grey. 
The perfect insect appears in October and November, 
and is very common amongst serub but is soon past. It 
occurs in company with B. basella, which it very closely 
resembles. It is, however, slightly smaller. The dark 
markings on the fore-wings are plainer than in the male 
of B. basella, which is almost uniform deep brown. It is 
also less mottled and darker than the female basella. 
According to Mr. Meyrick the antennal ciliations are 
shorter in the male of basella than in the male of politis.
