XI—THE PYRALIDAE. 208 
The expansion of the wings is barely { inch. The fore- 
wings are very pale brownish-ochreous, almost white, with a dull 
brown shading on the costa near the base and @ very conspicuous 
blackish discal spot; there is an indistinct, jagged, whitish, sub- 
terminal line, edged with pale brown towards base, sometimes 
emitting a faint loop which almost touches the discal spot; there 
is a series of blackish-brown terminal marks. The hind-wings 
are white, with a rather large dusky lunule and a wavy white 
sub-terminal line extending to within + of the tornus; near its 
termination this line is brilliant white and iridescent beside 
being here strongly edged with black; there is’a series of black- 
ish-brown sub-terminal marks. 
The perfect insect appears from December till Febru- 
ary. It frequents swampy forests. Sometimes it is fairly 
common amongst sedge (Gahnia setifolia), but is very loth 
to fly, usually secreting itself amongst the leaves of the 
sedge near the ground, and thus eluding pursuit. 
PYRALIDES. 
Maxillary palpi present. Fore-wings with q and 8 out of 9. 
Hind-wings without defined pecten of hairs on lower margin of 
cell, 4 and 5 closely approximated or stalked, 7 out of 6 near 
origin, free or anastomosing with 8. 
A family of moderate extent and general distribution, 
but the only three New Zealand species are not indigenous. 
Three genera are represented in New Zealand. 
1. DIPLOPSEUSTIS. 2. ENDOTRICHA. 
3. PYRALIS. 
Genus 1—DIPLOPSEUSTIS, Meyr. 
Labial palpi rather long, porrected, second joint with dense 
rather short projecting scales, forming a short apical tuft be- 
neath, terminal joint moderate, slender, obliquely ascending. 
Maxillary palpi moderate, triangularly dilated with scales. Fore- 
wings with 4 and 5 stalked. Hind-wings with 4 and 5 stalked, 7 
anastomosing with 8. (Plate D., figs. 50, 51 neuration of Diplop- 
seustis perieralis; fig. 52 head of ditto.) 
Perhaps contains only the following species. 

Sub-family 5. 
DIPLOPSEUSTIS PERIERALIS. 
(Diplopseustis perieralis, Walk., Cat., xix., 958 (perieresalis) ; 
Cymoriza minima, Butl., Proc. Zool. Soe., 1880, 684; Dip- 
lopseustis minima, Meyr., Trans. Ent. Soc. Lond., 1884, 
285; Trans. N.Z. Inst., xx., 63.) 
(Plate XXII.,; fig. 44 @.) 
This rather inconspicuous species has occurred at 
Auckland, Wanganui, Wellington, Christchurch, Dunedin, 
Wyndham and Invercargill, but is not common. 
The expansion of the wings is about 2 inch. The fore-wings 
are rather narrow, with the termen rather deeply indented below 
the apex, pale yellowish-brown or dull greyish-brown; there is a 
slightly curved, white-edged, blackish, transverse line at about 
4; a black discal dot; a brownish shading on the costa with 
several minute white dots bordered with blackish-brown; a very 
conspicuous blackish transverse line at 3%, edged with white to- 
wards the termen, and strongly curved outwards near the middle; 
the terminal area is shaded with yellowish brown, and the ter- 
men itself with blackish-brown or darker grey; the cilia are 
pale ochreous, barred with dark brown. The hind-wings are grey, 
speckled with black; the termen is slightly indented, with a wavy 
pale terminal line which cuts the apex of a blackish triangular 
spot. 
The perfect insect appears in February and March, 
and is sometimes attracted by light. According to Mr. 
OV 
Meyrick it is common in Sydney and Melbourne, but Aus- 
‘tralian specimens, although identical, are darker than New 
Zealand specimens. It also occurs in Fiji, Formosa, Bor- 
neo, and Assam. It is usually found near towns, and is 
probably attached to some cultivated plant. 
Genus 2.—HNDOTRICHA, Zell. 
Antennae in male fasciculate-ciliated. Labial palpi ascend- 
ing, second joint with projecting scales beneath, terminal short, 
exposed. Maxillary palpi very short. Thorax in male with 
patagia much elongated, terminating in long tuft. Fore-wings 
with veins 4 and 5 connate or stalked. Hind-wings with 4 and 
5 connate or stalked, 7 anastomosing strongly with 8. 
An Indo-Malayan genus of moderate size, of which 
only one species has reached New Zealand. 
ENDOTRICHA PYROSALIS. 
(ELndotricha pyrosalis, Guen., Lep., viii., 219.) 
(Plate XLVIIL., fig. 14 @.) 
A single specimen of this very distinct Australian spe- 
cies was taken by Mr. Hamilton at Mount Dennan in Feb- 
ruary, 1911. 
The expansion of the wings is slightly over # inch. The 
fore-wings, which have the costa strongly arched before the apex, 
are deep ochreous, there is an almost straight dark pink trans- 
verse line beyond the middle; inside this line there are a few 
scattered pink scales; outside it the whole wing is heavily sprin- 
kled with pink except on a fine sub-terminal line; the cilia are 
whitish with a brown basal line and pinkish tornal tuft. The 
hind-wings are bright ochreous, clouded with pink towards the 
termen; the cilia are pinkish with a brown basal line. 
Described and figured from an Australian specimen 
kindly lent to me by Mr. Philpott. 
Genus 3.—PYRALIS, Linn. 
Labial palpi ascending, second joint rough-scaled, terminal 
joint moderate. Maxillary palpi filiform. Fore-wings with 4 and 
5 stalked. Hind-wings with 4 and 5 stalked, 8 free. 
A genus of about 20 species, chiefly Indo-Malayan, but 
some of the species have been very widely spread. 
The single New Zealand species is a very common 
domestic insect, introduced through civilization. 
PYRALIS FARINALIS. 
(Pyralis farinalis, Linn., Syst. Nat. (10), 226; Meyr., Trans. N.Z. 
Inst., xvii., 122.) 
(Plate XXIV., fig. 23 9.) 
This well-known species is probably common in most 
eranaries and bakehouses throughout the country. 
The expansion of the wings is about 1 inch. The fore-wings 
are dull reddish-brown on the basal and terminal areas with the 
space between the first and second lines ochreous; the first line 
is pale ochreous strongly bent outwards near the middle; the 
second line is also pale ochreous with a very prominent rounded 
projection in the middle, almost reaching the termen; except at 
the apex, the terminal area is tinged with grey. The hind-wings 
are greyish-ochreous with two very wavy transverse lines. 
The larva feeds on flour and corn refuse. 
The perfect insect appears in March and April. It is 
generally distributed in Australia and occurs also through- 
out most of the world, but is probably Central Asiatic in 
origin.
