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. 
b. Adoa. lotinana, n. sp. 
Media, alis ant. dilute ochreis, coste dimidio anteriori dorsoque 
anguste fuscis, margine postico late fusco-suffuso, plumbeo-strigulato, 
fascia media perobliqua fusca dimidium non superante, cilis albis; 
post. griseis. 
Male, 17 mm.; female, 21. mmm.—Head and thorax light ochreous. Palpi 
elongate, light ochreous, externally suffused with dark fuscous. Antenne 
light ochreous, sharply annulated with dark fuscous. Abdomen whitish- 
ochreous. Legs whitish-ochreous, anterior and middle tibie and tarsi suf- 
fused 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, indis- 
 tinetly 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 Christ- 
church, and I am indebted to him for my types.
