XI.—THE 
and Kaitoke in the North Island. In the South Island it 
has oecurred on the Tableland of Mount Arthur at eleva- 
tions between 3,000 and 4,000 feet above the sea-level as 
well as at Castle Hill, Lake Wakatipu, Fiordland and Sea- 
ward Moss, near Invereargill. It is also found on the 
Chatham Islands. 
The expansion of the wings is about 14 inches. The fore- 
wings are dark brown slightly paler towards the costa and dor- 
sum; there is @ fine silvery streak on the costa from the base to 
the apex often narrowly bordered with brown on the costal edge 
at about 4; a moderately broad central longitudinal ‘silvery 
streak, considerably narrower towards the base, and slightly nar- 
rower towards the termen. The hind-wings are pale brownish- 
ochreous, darker towards the termen; the cilia of all the wings 
are dull white. The head, palpi and central portions of the thorax 
are dull ochreous. 
The perfect insect appears from December till March. 
It is widely distributed, frequenting open swampy situa- 
tions, but is not a common species. 
CRAMBUS APICELLUS. 
(Crambus apicellus, Z., Mon. Cr., 31; Meyr., Trans. N.Z. Inst., 
xv., 26.) 
(Plate XX., fig. 20 @.) 
This very distinct and neatly-marked species seems to 
be generally distributed throughout the country. 
The expansion of the wings is about 1 inch. The fore-wings 
have the costa rather strongly arched, broadly bordered with sil- 
very white from about + almost to the apex; this is followed by 
a dark ochreous-brown longitudinal stripe; at the end of this 
stripe immediately below the! apex there is a minute, triangular 
silvery mark; there is a rather broad, silvery white central 
longitudinal stripe finely edged with brown; the rest of the 
wing is pale brownish-ochreous, shaded with white on the dor- 
sum near the middle; the cilia are grey, narrowly white at the 
base. The hind-wings are pale greyish-ochreous, darker near the 
termen; the cilia are pale ochreous. 
The perfect insect appears from October till February. 
It frequents swampy situations and is often found on 
mountains at elevations of from 2,000 to 3,000 feet’ above 
the sea-level. Although widely distributed it is usually 
very local, and only frequents areas of limited extent. 
CRAMBUS PARAXENUS. ' 
(Crambus paraxenus, Meyr., Trans. N.Z. Inst., xvii., 137.) 
(Plate XX. fig. 17 @.) 
This local, species has occurred at} Macetown and Lake 
Wakatipu at elevations ranging from 2,000 to 4,000 feet 
above the sea-level. 
The expansion of the wings is 1} inches. The fore-wings 
are narrow, with the costa arched and the termen very oblique; 
pale brassy ochreous; there is a slightly curved white streak 
from the base to the ,termen above the middle; this streak is 
rather thicker and a little bent at about % and its edges are 
faintly clouded with greyish, especially ,in the disc; the costal 
edge is very narrowly edged with white on the apical third, and 
there is a small white patch on the termen between the apex 
and the central streak; the cilia are greyish-ochreous barred 
with white. The hind-wings are pale greyish-ochreous, with 
white cilia. 
PYRALIDAE. 167 
The perfect insect appears in November and Decem- 
ber and frequents dry slopes on the mountains. Mr. Mey- 
rick points out that this species is ‘‘ closely allied to C. 
vittellus, with which it agrees in the distinctly barred cilia 
of the fore-wings, and resembling the most simply-marked 
forms of that species, but, constant; larger, more ochreous- 
yellowish, not fuscous; the antennae of the male somewhat 
more slender, the apex of the fore-wings less pointed and 
the termen not distinctly sinuate, the terminal black dots 
absent, and the hind-wings greyer, not ochreous tinged.”’ 
Described and figured from a specimen kindly lent to me 
by Mr. Philpott. 
CRAMBUS ABDITUS. 
(Crambus abditus Philp., Trans: N.Z. Inst., ly., 212.) 
(Plate L., fig. 18 9.) 
uo 
This species was discovered by Mr. C. Lindsay at Ota- 
rama, Canterbury. 
The expansion of the wings is 1$ inches. The fore-wings 
are elongate with the termen extremely oblique; brassy-ochreous; 
the costa is narrowly edged with white throughout; there is a 
broad straight longitudinal white streak from base to termen 
above middle, but no white margin on dorsum and no white band 
on the thorax. The hind-wings are white, faintly tinged with 
ochreous, The cilia, of all the wings are white. 
The perfect insect appears in October. * 
CRAMBUS. OBSTRUCTUS. 
(Crambus obstructus, Meyr., Ent. Mo. Mag., 1911, 82.) 
(Plate XX., fig. 5 @.) 
This interesting species was discovered by the late Dr. 
G. B. Longstaff on March 8th, 1910, three specimens hav- 
ing flown into the train at Lumsden whilst he was passing 
through that place on a New Zealand tour. It has also 
occurred on Ben Lomond and in the Routeburn Valley 
near Lake Wakatipu as well as in other localities in the 
extreme South, but is not a common species. 
The expansion of the wings is slightly over 1 inch. The 
.fore-wings are brownish-ochreous, darker on the costa; there is 
a white longitudinal streak from the base to the termen above 
the middle, broken at about % by an irregular blackish-brown 
blotch; the white streak is suffused on the termen, and there is 
a series of very minute terminal dots. The hind-wings are whit- 
ish-ochreous. 
The perfect insect appears from January till March 
and frequents open tussock country. It has probably often 
been mistaken for the very common and variable Crambus 
vittellus. 
CRAMBUS VITTELLUS. 
(Crambus vittellus, Dbld., Dieff. New Zeal., ii., 289; Crambus 
nexalis, Walk., Cat. xxvii. 178; Crambus transcissalis, 
ibid., 178; Crambus bisectellus, Z., Mon. Cramb., 32; Cram- 
bus incrassatellus, ibid., 32; Crambus vapidus, Butl., Proce. 
Zool. Soc. Lond., 1877, 399; Meyr., T.N.Z. Inst., xv., 27.) 
(Plate XX., figs. 2, 3, 4, varieties.) 
This species is very common and generally distributed 
throughout the country. It is also found on the Chatham 
Islands.
