Differs from Pyrgotis in the absence of the thoracic crest. Of the three known species, one is Australian, and the other two belong to New Zealand, not closely approaching the Australian species. In all the sexes differ more or less conspicuously.
5. Adox. lotinana, n. sp.
Media, alis ant. dilute oehreis, costæ dimidio anteriori dorsoque auguste fuscis, margine postico late fusco-suffuso, plumbeo-strigulato, fascia media perobliqua fusca dimidium non superante, ciliis albis; post. griseis.
Male, 17 mm.; female, 21 mm.—Head and thorax light ochreous. Palpi elongate, light ochreous, externally suffused with dark fuscous. Antennæ light ochreous, sharply annulated with dark fuscous. Abdomen whitish-ochreous. Legs whitish-ochreous, anterior and middle tibiæ and tarsi suffused with dark fuscous, except at apex of joints. Forewings moderate, in male triangular, in female more oblong, costa gently arched, hindmargin straight, rather oblique, rounded beneath; light ochreous; inner margin and anterior half of costa narrow suffused with dark fuscous, mixed with reddish fuscous; hindmargin broadly suffused with reddish-fuscous, indistinctly strigulated with leaden-grey, the veins remaining pale-ochreous: posterior half of costa strigulated with dark fuscous; a very oblique moderately broad ill-defined reddish-fuscous streak from costa before middle, hardly reaching half across wing: cilia white, with a dark fuscous basal line. Hindwings grey, lighter in female; cilia whitish, with a grey basal line.
Separable from the next species by the darker hindwings, almost wholly white cilia of forewings, and larger size.
The larva feeds on Arundo conspicua ("toi grass"), but I do not know in what manner. Mr. R. W. Fereday informs me that he bred the species from conspicuous firm white cocoons, attached openly to the surface of the leaves.
Mr. Fereday obtained several specimens in this manner near Christchurch, and I am indebted to him for my types.
