Mryricx.—-On New Zealand Micro-Lepidoptera. 129 
and eilia grey, somewhat reddish-tinged, lower margin of third segment 
fringed with coarse black scales on basal half, a patch beyond middle, and 
a small spot at apex. 
Nearly allied to P. haasti, but larger, and readily separated by the 
reddish-fuscous ground-colour, white costal spot beyond the dark triangular 
blotch, and abundant black scales of the cilia of hindwings. 
Otira River, Christchurch, Dunedin, and Invercargill; common from 
December to March, amongst bush. 
12. Platypt. heliastis, n. sp. 
Male.—19 mm. Head, palpi, antennw, thorax, abdomen and legs 
reddish-fuscous, somewhat mixed with whitish, posterior tarsi white. 
Forewings light brownish-ochreous, suffused with reddish-fuseous towards 
base and inner margin, and less strongly on hindmargin, and slightly 
strewn with whitish in dise; costa suffusedly ochreous-whitish towards 2, 
towards base suffused with dark fuscous and obscurely spotted with whitish ; 
a dark fuscous dot before and below cleft: cilia dark reddish-fuscous, on 
costa whitish-ochreous. Hindwings and cilia light grey, slightly reddish- 
tinged, lower margin of third segment fringed with coarse black scales from 
base to 3. 
Immediately recognized by the entire absence of the dark fuscous costal 
triangle, and other markings. 
Castle Hill; one specimen received from Mr. J. D. Enys. 
HYDROCAMPID. 
Maxillary palpi resting on labial, rarely dilated. Abdomen in male 
with uncus well-developed. Forewings with vein 7 separate from 9 (rarely 
stalked with 10). Hindwings with lower median vein naked; vein 7 from 
angle of cell. 
Represented in New Zealand by a single species only, which cannot be re- 
garded as belonging to the endemic fauna; it occurs commonly in South-east 
Australia, and has probably migrated thence in comparatively recent times. 
6. HyGRAULA, n. g. 
Face tolerably vertical. Ocelli absent. Tongue moderate. Antenne $ 
of forewings, in male filiform, shortly pubescent-ciliated. Labial palpi 
moderate, 14, nearly straight, porrected, second joint with short rough 
scales, terminal joint moderate, obtuse. Maxillary palpi moderate, por- 
rected, slightly dilated with scales, truncate. Posterior tibie with outer 
spurs half inner. Abdomen rather elongate, in male with large broad 
exserted valves, and long curved uncus. Forewings with veins 4 and 5 
closely approximated at base, 10 rising out of stalk of 8 and 9. Hindwings 
as broad as forewings, veins 4 and 5 from a point 6 and 7 stalked, 8 
anastomosing with 7 from before origin of 6 to 1.
