AXVI.—_THE 
P. steropucha. A very bright-coloured form occurs at 
Kaeo, north of Auckland, and is depicted on Plate 
XXXIV, fig) 3. 
The larva, which feeds on Oarex Solandri, and probably 
other native grasses, is about 4 inch long; cylindrical, attenu- 
ated at each end, very much. attenuated posteriorly. The head 
is pale green with several very fine brownish-black stripes; the 
body brilliant green with broad paler yellowish-green dorsal 
line; intersegmental spaces yellow, very conspicuous; two rows 
of minute black warts around each segment, each wart emitting 
a short black bristle; legs brownish ochreous. 
The larva is generally sluggish, resting at full length 
on the leaves of its foodplant, where it is hard to see. 
When disturbed, however, it moves with great rapidity. 
The cocoon is elongate-elliptical, with the ends long- 
pointed, pale brownish, the black spots on the enclosed 
pupa sometimes faintly visible through the texture of the 
cocoon. There is a distinct ridge along the top of the 
cocoon, and the larval skin is ejected through a sht at 
its posterior end, the skin usually remaining attached to 
the outside. In most cases this slit closes up so that the 
manner of the ejection of the cast larval skin from the 
cocoon is not apparent. The cocoon is usually attached 
to one of the leaves of the foodplant. 
The perfect insect generally appears in February 
and March, and is found in open grassy glades amongst 
beech forest or sub-alpine serub. An early brood was 
found, by Mr. Philpott, on Mount Arthur in November. 
PROTOSYNAEMA ERATOPIS. 
(Protosynaema eratopis, Meyr., Trans. N.Z. Inst., xviii., 174.) 
z GEAR. RO OMINY gales Tb 480) 
This very clearly-marked species has occurred at 
Mount Arthur, Castle Hill, and Otira River at clevations 
of from 2,000 to 3,000 feet above the sea-level. It is a 
very local insect, though usually abundant where found. 
The expansion of the wings is about 4 inch. The antennae 
in the male are clothed with dense scales from the base to 
4, in the female to 4. The fore-wings are rather broad, oblong, 
with the termen slightly oblique; bright yellow-ochreous with 
the markings margined with brown; there is a curved white 
streak from the base, almost touching the dorsum at #4, fol- 
lowed by a curved silvery band from the costa near the base 
to the dorsum beyond 4; a broad curved white streak on the 
costa at 4; two straight transverse bars cross the wing near 
the middle, the first thin, silvery in the middle; the second 
broader, clear white, almost throughout; a large, oval white, 
patch is situated in the disc beyond the middle traversed by 
six fine black lines; there is one short white mark and one sil- 
very band on the costa near the apex; «a large black tornal spot 
containing three coppery- or violet-metallic spots and a black 
spot nearer the disc containing one metallic spot. The hind- 
wings are grey. 
The perfect insect appears in December and Janu- 
ary and generally frequents sub-alpine scrub. It flies 
most freely in the hottest sunshine. When resting it 
stands very erect with the head slightly raised and the 
antennae extended forwards and upwards, each often 
alternately waved; the wings form a very steep roof. In 
this posture the insect is evidently very much on the 
TINEIDAE. 327 
alert, and ready to take wing at the slightest alarm. As 
already pointed out by Mr. Meyrick the general resem- 
blance of this species to a typical Glyphipteryx is very 
extraordinary, and this resemblance is most marked when 
the insect is resting. 
Genus 5.—PHYLACODES, Meyr. 
Antennae thickened with scales on basal halt, basal joint 
without pecten. Fore-wings with vein 7 and 8 stalked. Hind- 
wings with 3 and 4 rather approximated. 
An endemic genus represented by one species only. 
PHYLACODES CAUTA. 
(Phylacodes cauta, Meyr., Trans. Ent. Soc. Lond., 1905, 242.) 
(Plate XXXIV., fig. 16.) 
This very rare species was discovered by Mr. J. H. 
Lewis at Ida Valley, Central Otago. 
The expansion of the wings is somewhat under ¢; inch. 
The antennae are densely scaled from near the base to consider- 
ably beyond the middle. The fore-wings are elongate with the 
costa abruptly arched near the middle and the termen slightly 
oblique; warm brownish-ochreous,; there is a broad brown longi- 
tudinal central streak extending from the base to the termen; 
this streak is darkest on the fold and becomes fainte1’ and wider 
towards the termen; there are one or two bluish or black discal 
dots beyond the middle and a few scattered brown dots. The 
hind-wings are greyish-brown, darkest near the apex. 
Evidently very variable in the depth of the general 
colouring; in some specimens the central longitudinal 
streak is very faint and diffused and extends as far as 
the dorsum. 
Genus 6—CADMOGENES, Meyr. 
Head with appressed scales, side-tufts somewhat raised; 
ocelli posterior; tongue developed. Antennae #, basal joint 
elongate, without pecten. Labial palpi long, recurved, second 
joint reaching base of antennae, thickened with appressed scales, 
terminal joint shorter than second, scaled, pointed. Maxillary 
palpi obsolete. Posterior tibiae smooth-scaled. Fore-wings vein 
2 from angle, curved, 6-8 straight, slightly approximated towards 
base, 7 to costa, 9 and 10 somewhat approximated at base, 11 
from middle. Hind-wings 1, elongate-oblong-ovate, cilia 3; 2 
from rather near angle, 3 from angle, 4 rather approximated to 
3 towards base, 5 parallel, transverse vein inwards-oblique from 
4 to 5, 6 and 7 rather approximated towards base. (Plate G., 
figs. 31, 32, 33 neuration and head of Cadmnogenes literata.) 
Belongs to group of Orthenches, from which genus it 
differs by terminal joint of labial palpi shorter than 
second, absence of maxillary palpi, and costal termina- 
tion of vein 7 of forewings. This interesting form sug- 
eests some affinity with Depressaria and Cryptolechia, and 
may indicate the origin of the Oecophorides from the 
Plutellides, in which case it would be of high phyloge- 
netie importance. 
Only one species is known at present. 
CADMOGENES LITERATA. 
(Cadmogenes literata, Meyr., Trans. N.Z. Inst. liv., 168.) 
(Plate XLIX., fig. 11 @.) 
This species has occurred at Kauri Gully and Taka- 
puna, near Auckland, and at Silverstream Upper Hutt, 
near Wellington.
