XI—_THE 
CRAMBUS CRENAEUS. 
(Crambus crenaeus, Meyr., Trans. N.Z. Inst., xvii., 135.) 
(Plate XX., fig. 9 9.) 
This fine species is very common on the Tableland of 
Mount Arthur at elevations of from 3,600 to 4,000 feet 
above the sea-level. It has also been found at'similar alti- 
tudes on Arthur’s Pass, and on several of the mountains 
at the head of Lake Wakatipu. It occurs at lower altitudes 
at Springfield and near Dunedin. 
The expansion of the wings is about 14 inches. 
wings are pale brownish-ochreous, slightly brassy tinged and 
much browner in the middle; there is a strdight longitudinal 
white streak from the base to the termen above the middle and 
the dorsum is very narrowly margined with white ‘close to the 
base; there are no other white markings. The hind-wings are 
very pale greyish-white; the cilia of all the wings are white. 
The palpi are very long. The head and thorax are pale ochreous 
with the sides of the palpi and thorax pale brown. 
This handsome insect appears in January and Febru- 
ary. It is often very abundant on grassy mountain sides, 
and flies readily in calm sunny weather. On cold cloudy 
days, however, not a specimen is to be seen, the moths 
retreating into the midst of the tussocks, where their pro- 
tective colouring and secretive habits usually prevent their 
discovery, even when specially searched for. On the Mount 
Arthur Tableland, I have observed this insect assembling 
in large numbers on veronica flowers, in shady places, at 
about 6 p.m.

CRAMBUS HAPLOTOMUS. 
(Crambus haplotomus, Meyr., Trans. N.Z. Inst., xv., 23.) 
(BlalerQxexe tien) 4).) 
This pretty insect has been taken at Castle Hill at 
elevations of from 2,500 to 3,000 feet and at Arthur’s Pass 
between 4,000 and 5,000 feet. 
the head of Lake Wakatipu. 
The expansion of the wings is about 14 inches. The fore- 
wings are rather dull ochreous, brassy-tinged; the costa is very 
finely edged with white; there are two or three very fine, short, 
white streaks below the apex near the termen, a slender, well 
defined central longitudinal white streak from the base to the 
termen, narrower near the base and slightly curved towards 
the termen; it is finely bordered below with dark brown from 
the base to about 4 and with paler brown above near the ter- 
men; there are seven extremely minute black dots on the ter- 
men. The hind-wings are pale grey, shaded with darker grey 
towards the termen. The cilia of all the wings are dull white. 
Mr. Meyrick remarks ‘‘ that this species and C. callir- 
rhoits differ somewhat in form of wing from those most 
nearly allied to them, the fore-wings being somewhat less 
dilated and the termen less perceptibly sinuate and more 
stronely rounded. C. haplotomus differs from all its near- 
est allies in the absence of the broad white thoracic stripe 
(only in the much paler C. simplex is this occasionally 
obsolete) and in the presence of a complete terminal row 
of minute black dots.’’ 
This species frequents the open grassy spaces at Para- 
dise, Glenorehy and Kinloch, near the head of Lake Waka- 
tipu. 
It also occurs sparingly at.

CRAMBUS ENCHOPHORUS. 
(Crambus enchophorus, Meyr., Trans. N.Z. Inst., xvii., 136.) 
(Plate XX., fig. 16 9.) 
This species has occurred on the Dun Mountain, Mt. 
Arthur and at Castle Hill at elevations of from 2,000 to 
4,000 feet above the sea-level. It has also been taken at 
Waikari and on the Otago Peninsula. 
The expansion of the wing is about 14 inches. The fore- 
wings are dull brownish ochreous with the veins marked in pale 
ochreous or dull white; there is an obscure white stripe on the 
costa, a rather slender, almost straight central white streak 
faintly edged with brownish black, a small brown mark on the 
dorsum near the base, a curved row of black dots on the veins 
before the termen and another :row on the termen. The hind- 
wings are pale dull ochreous, slightly darker towards the termen. 
The cilia of all the wings are dull white. The palpi are white; 
there is a central white stripe on the thorax and two short white 
stripes on the sides of the thorax. 
The perfect insect appears in February and March. 
It is not by any means eammon or generally distributed. 
In this species the markings are less definite than 
in C. callirrhous and the two rows of black dots are absent 
in that species. The present insect is larger than C. pedzas, 
which is duller and greyer with the termen more sinuate 
and distinetly dotted with black. 
CRAMBUS. CALLIRRHOUS. 
(Crambus callirrhous, Meyr., Trans. N.Z. Inst., xv., 24.) 
(Plate XX., fig. 34 @.) 
This very neatly-marked species is not generally dis- 
tributed. It has occurred at Christchurch, Castle Hill, 
Lake Guyon, and at New River, near Invereargill. 
The expansion of the wings is 14 inches. The fore-wings 
are deep ochreous, slightly brassy-tinged; the costa is finely 
edged with white; there are two very fine white lines below the 
apex; the upper from about five-sixzths, the lower from half; a 
rather narrow, almost straight central streak from the base to 
the termen above the middle, very finely margined with grey; 
there is a very indistinct fine white streak from the base along 
the :dorsum to 4, thence extending slightly inwards to the tor- 
nus. The hind-wings are greyish-ochreous. 
The perfect insect appears in January, February and 
March, and frequents sandhills. 
CRAMBUS SCITULUS. 
(Crambus scitulus, Philp., Trans. N.Z. Inst., lvi., 390.) 
CPiagte Tiles Zor a.) 
This very distinetly-marked, handsome species was 
discovered by Mr. S. Lindsay, on Mount Arthur, at an 
altitude of 4,000 feet above the sea-level. 
The expansion of the wings is 1} inches. In its general 
markings it closely resembles Crambus callirrhous, but differs in 
the following important respects:—The fore-wings) are somewhat 
broader; their ground colour is very dark brassy brown, appear- 
ing in certain lights almost black, especially towards base; there 
is a series of black terminal marks, and the veins are finely 
marked in black before termen, 
The perfect insect appears in January.
