40 Transactions. — Zoology. 



Differs from PyrgoUs 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 ochreis, costse dimidio anteriori dorsoque 

 anguste 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. Antennae 

 light ochreous, sharply annulated with dark fuscous. Abdomen whitish- 

 ochreous. Legs whitish-ochreous, anterior and middle tibiae 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- 

 tinctly 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. E. 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.
