Meybick. — On New Zealand Micro-Lepidoptera. 129 



and cilia 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 Eiver, Christchurch, Dunedin, and Invercargill ; common from 

 December to March, amongst bush. 



12. Platypt. heliastis, n. sp. 



Male. — 19 mm. Head, palpi, antennas, thorax, abdomen and legs 

 reddish-fuscous, somewhat mixed with whitish, posterior tarsi white. 

 Forewings light brownish-ochreous, suffused with reddish-fuscous towards 

 base and inner margin, and less strongly on hindmargin, and slightly 

 strewn with whitish in disc ; costa suffusedly ochreous-whitish towards f , 

 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 f . 



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. 

 HYDBOCAMPnm 



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. 



Kepresented 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. Hygeaula, n. g. 



Face tolerably vertical. Ocelli absent. Tongue moderate. Antennas % 

 of forewings, in male filiform, shortly pubescent-ciliated. Labial palpi 

 moderate, 1J, nearly straight, porrected, second joint with short rough 

 scales, terminal joint moderate, obtuse. Maxillary palpi moderate, por- 

 rected, slightly dilated with scales, truncate. Posterior tibias 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 f .
