The expansion of the wings varies from about $ to seven- 
sixteenths of an inch. The fore-wings are narrow with the ter- 
men very oblique and the apical lobe distinct; dull brown, 
sometimes clouded with white near the costa, with dark-edged 
white markings; there is a broad curved longitudinal streak 
along the dorsum reaching beyond the middle of the wing; a 
series of rather indistinct costal streaks; a rather short oblique 
tornal streak terminating in a silvery spot and another small 
metallic mark near the termen. The hind-wings are brownish- 
grey, ! ot ba 
There is considerable variation in the intensity of the 
eround colouring. Some specimens are quite brown with 
distinet costal streaks; others have a few faint bluish dots 
on the apical portions of the wing. 
The perfect insect appears from November till March, 
and frequents dry grassy places, where it is sometimes 
fairly common. 
GLYPHIPTERYX CALLIACTIS. 
(Glyphipteryx calliactis, Meyr., Trans, N.Z. Inst., xlvi. 112.) 
(Plate XXXIV., fig. 12 4, 13 9; Plate III., fig. 35 larva.) 
This large and very handsome species has occurred at 
Days Bay, Silverstream, and Kaitoke near Wellington. 
The expansion of the wings is slightly over % inch. The 
fore-wings are elongate-trianguldr with the apical lobe well- 
developed and the termen strongly bowed and very oblique; 
black with bronzy reflections; the male has Several slender 
metallic blue stripes on the costa from about 4 to % and two 
short crescentic white markings before the apex; there is a 
subterminal series of elongate dull metallic-green spots and a 
fine metallic-green stripe on the dorsum just before the tornus. 
In the female the markings are much more numerous and dis- 
tinct; there are seven oblique white costal streaks, tinged with 
vivid metallic blue or purple towards the disc; three broad 
curved white bars on the dorsum—the two outermost tinged 
with vivid metallic purple towards the disc, and two metallic 
purple spots near the termen. In both sexes the hind-wings 
are grey becoming almost black at the apex. 
There is sight variation in the size and intensity of 
the markings in both sexes, and some male specimens have 
faint traces of the conspicuous white dorsal markings of 
the female. 
The larva lives inside the flower-stems of sedge 
(Gahnia setifolia), from November till September, feed- 
ing on the soft inner pith. Its length when full-grown is 
slightly over $ inch. The head is very small, brown and 
shining; the rest of the body soft, very stout, suddenly 
tapering towards each extremity; bright yellowish-ochre- 
ous; there is a brown horny plate on the second segment; 
the posterior edge of the twelfth and the whole of the 
anal segment are horny and blackish-brown, the anal seg- 
ment being furnished with four rather prominent tuber- 
eles; the legs and prolegs are small. 
The pupa is enclosed in a thin silken cocoon within 
the flower-stem of the sedge, and is usually placed near a 
joint. The larva drives a tunnel almost through the wall 
of the stem, the outermost skin alone remaining intact so 
that its dwelling place is not revealed from the exterior. 
This provides a safe means of exit for the future moth. 

TINEIDAE. 
The perfect insect appears in September, October and 
November, specimens bred from flower-stems kept indoors 
emerging fully a month earlier. It flies actively in hot 
sunshine, amongst sedges in beech forests. 
GLYPHIPTERYX IOCHEAHRA. 
(Glyphipteryx iocheaera, Meyr., Proc. Linn. Soc. N.S.W., 1880, 
243.) 
(Plate XXXIV., fig. 18 9; Plate III., fig. 22 larva; 23 pupa.) 
This rather dull-looking species is apparently com- 
mon and generally distributed throughout the country. 
The expansion of the wings is slightly over % inch. The 
fore-wings are rather elongate, the apex with a distinct lobe and 
the tornus rounded very dull greenish-bronze with black-edged 
dusky-white markings; there is a very oblique stripe on the 
costa beyond the middle, five oblique stripes near the apex and 
two on the termen; the apical lobe is black with a tuft of black 
cilia above and below it.. The hind-wings are dark grey with 
bronzy reflections. 
The larva lives in the stems of the common rush 
(Juncus), during the autumn and winter, feeding on the 
pith amongst which it drives numerous galleries. These 
communicate with the exterior by round openings through 
the green outer stem of the rush; but, prior to the exit of 
the perfect insect, the openings are covered with a thin 
pellicle evidently left by the larva as a protection. The 
termination of the burrow is, however, visible from the 
outside as a round brown spot on the stem of the rush. 
The length of the larva when full-grown is about + 
inch; stout with minute legs and prolegs. The head is 
blackish-brown and shining, the second segment has a 
large horny blackish dorsal plate, the other segments are 
pale green, darker beneath, each has a pale brownish dor- 
sal mark; there is an interrupted blackish dorsal line on 
the anterior portion of the larva, the last segment is black- 
ish-brown and horny, there are a few short isolated 
bristles. 
The pupa is very elongate, pale ochreous-brown; the 
anterior wing-case is dull silvery-white, the posterior wing- 
case and abdomen are pale green, the cremaster is rounded 
and furnished with several black bristles, the eyes are 
black and very conspicuous. 
The perfect insect appears in November and Decem- 
ber. It delights in hot sunshine and is occasionally found 
swarming amongst rushes, but the best specimens are 
obtained by rearing them from the stems containing the 
larvae. 
GLYPHIPTERYX LEPTOSEMA. 
(Glyphipteryx leptosema, Meyr., Trans. N.Z. Inst., xx. 87; 
xliii., 75.) 
(Plate XXXIV., fig. 9 @.) 
This very distinct little species has occurred at Auck- 
land, Waimarino, Kaitoke near Wellington, and at the 
Bluff. 
The expansion of the wings is 2 inch. The fore-wings are 
elongate-triangular with a distinct apical lobe and oblique 
rounded termen; bronzy-black; there is a small white mark on 
the dorsum near the base; two very oblique fine whitish bars
