XVII—THE 
BORKHAUSENIA INNOTELLA. 
(Oecophora innotella, Wialk., Cat. xxix., 652; griseata, Meyr., 
Trans NeZee LS te xvi oo.) 
(Plate XXIX., fig. 21.) 
This rather obscurely-marked species is generally dis- 
tributed throughout the country. 
The expansion of the wings is slightly over § inch. The 
. fore-wings, which are dilated towards the termen, are pale oclre- 
ous-brown with darker brown markings; there is a rather broad 
wavy line from the dorsum at 4 nearly reaching the first discal 
2 
dot; the second discal dot is situated at about ? and is often 
connected with the tornus by an oblique line; there is a doubly 
curved sub-terminal line frem the costa before the apex to the 
tornus. The hind-wings are grey. 
There is considerable variation in the depth of the 
ground colour and also in the distinctness of the markings. 
The perfect insect appears from December till March. 
It frequents open forests or scrub and is sometimes fairly 
common. Apparently it has a distinet preference for the 
silver tree fern (Cyathea dealbata.) 
BORKHAUSENIA MARCIDA. 
(Borkhausenia marcidd, Philp., Trans. N.Z. Inst., lvii., 706.) 
This very obscure form was found by Mr. S. Lindsay 
at Bottle Lake, near Christchurch. It has also occurred at 
tovernor’s Bay and Mount Grey, Canterbury. 
It is very like some of the pale forms of B. innotella, from 
which it apparently differs in its peculiar opaque-looking whit- 
ish colouring, very indefinite brownish speckling and absence of 
any distinct sub-terminal line. Some specimens ‘have no mark- 
ings. Mr. Philpott considers that the differences in the terminal 
appendages of the male entitle this form to specific rank. 
Described from a specimen lent by Mr. Philpott. 
BORKHAUSENIA SERENA. 
(Borkhausenia serena, Philp., Trans. N.Z. Inst., lvi., 403.) 
(Plate LI., fig. 10 9.) 
This species was discovered by Mr. Philpott, at Sunny- 
side, Southland. 
The expansion of the wings is nine-sixteenths of an inch. 
The fore-wings are very pale ochreous, more or less densely 
strewn with brown scales; a broad longitudinal streak of deep 
brown scales on basal third of costa; a cluster of blackish-brown 
scales below middle of fold; a much less distinct patch above 
this near end of fold; @ conspicuous streak of blackish-brown 
scales from disc to tornus; very large irregular patches of thinly 
strewn pale brown scales in disc, and along termen, the inter- 
vening spaces having a few isolated pale brown scales. The 
hind-wings are pale brownish-grey. The head, thorax and dbdo- 
men are brown, except two pale ochreous patches, one on each 
side of the anterior portion of the thoraz. 
The perfect insect appears in January. 
Deseribed and figured from a specimen kindly lent to 
me by Mr. Philpctt. 
BORKHAUSENIA FENESTRATA. 
(Borkhausenia fenestrata, Philp., Trans. N.Z. Inst., lvi., 404.) 
This is a very obscure greyish-brown species, found by 
Mr. Philpott on the Dun Mountain, near Nelson, and stated 
TINEIDAE. 269 
to be chiefly distinguished by the second discal spot, which 
has the lower half white. It is fairly common in forest, at 
altitudes of from 2,000 to 3,000 feet above sea-level. Ex- 
panse of wings $ inch. 
BORKHAUSENIA BRACHYACMA. 
(Borkhausenia brachyacma, Meyr., Trans. N.Z. Inst., xli., 13.) 
(Plate XXIX., fig. 23 4.) 
This is another very obscure, but distinct species, 
which was discovered at Invereargill by Mr. Philpott. 
The expansion of the wings is slightly under 3 inch. The 
fore-wings are whitish-ochreous densely speckled with brown; 
there is an obscure brownish patch on the dorsum near the base 
limited by a fine inwardly oblique blackish line; a rather con- 
spicuous spot on the fold; a very large brown discal spot at 2; 
a small patch on the dorsum just before the tornus and a wavy 
sub-terminal line. The hind-wings are pale grey. The terminal 
joint of the palpi is very short and the antennae are pubescent- 
ciliated. 
The perfect insect appears in October and November, 
and is common amongst manuka (Leptospermum) and 
other shrubs. It also occurs in forests and open swamps. 
In general appearance it is very similar to B. innotella, but 
may be distinguished by the special characters italicised in 
the above description. 
BORKHAUSENIA PENTHALBA. 
(Borkhausenia penthalea, Meyr., Trans. Ent. Soc. Lond. 1905, 
239.) 
(Plate XX, fig. 13 4.) 
This rather distinctly-marked species has occurred in 
the neighbourhood of Wellington and at Mangatariri River, 
Tararua Range. 
The expansion of the wings is slightly over § inch. The 
forewings are creamy-white more or less speckled with pale 
brown, especially towards the base and costa; there is an oblique 
brown mark on the fold at 4, a minute discal dot above it and 
a larger discal dot at 2; a very large irregular dark brown patch 
extends from a little before the apex almost to the tornus, leav- 
ing a narrow terminal band of the ground colour; the cilia are 
dull white. The hind-wings are pale grey, darker towards the 
termen. 
There is considerable variation in the brown patch on 
the fore-wings, which is occasionally divided into two dis- 
tinct spots. The ground colour also varies, being much 
whiter in some specimens than in others; the discal dots 
are sometimes clouded with orange-brown. 
The perfect insect appears from December till Febru- 
ary, and frequents forests. It is a rare species. 
BORKHAUSENIA AMNOPIS. 
(Borkhausenia amnopis, Meyr., Trans. N.Z. Inst., xlii., 65; ibid. 
xliii., 65.) 
(Plate XXIX., fig. 33.) 
This rather pretty variegated species was discovered 
by Mr. Philpott at Invereargill. It has also occurred at 
Mataura.
