Philpott. — New Species of Lepidoptera. 121 



Differs from C. oxyina in the larger size, absence of lateral thoracic 

 spots, and more uniform colour. 



Ben Lomond, in November. Common on Nothofagus Solandri, at 

 2,000 ft, to 3,000 ft. 



„ . . Hepialidae. 



Ponna fusca sp. nov. 



cJ. 32-35 mm. Head and thorax dark brownish-ochreous. Antennae 

 shortly bipectinate. Abdomen grey. Forewings, costa straight, apex obtuse, 

 termen obliquely rounded ; dark fuscous-brown ; veins outlined with 

 darker ; a triangular white dot below costa at ^, margined beneath with 

 black ; an irregular more or less triangular white spot beyond this, mar- 

 gined with black ; an irregularly sinuate white mark from, base at middle to 

 before \, suffusedly margined with black ; a white dot on dorsum at \, mar- 

 gined beneath by a A-shaped black mark ; an indistinct chain of white- 

 margined fuscous spots from costa near apex to tornus, ending on tornus 

 in a A-shaped black mark ; a subterminal series of obscure white-centred 

 fuscous marks ; a series of interneural triangular fuscous dots on termen : 

 cilia ochreous, indistinctly barred with fuscous. HindAvings fuscous : cilia 

 as in forewings. 



$. 35 mm. Forewings light fuscous, markings almost obsolete ; indi- 

 cations of a dark streak from base below costa, another below this, and a 

 white spot in disc at about \ : cilia fuscous mixed with ochreous. Hind- 

 wings pale fuscous-grey : cilia as in forewings. 



Nearest to P. despecta, but smaller, and with a different arrangement 

 of spots. The lower basal streak seems to be the most distinctive marking. 



Bold Peak, Humboldt Range ; and Ben Lomond, Wakatipu. The first 

 specimen brought under my notice was taken by Mr. C. Fenwick, who 

 found it common on Bold Peak, at 4,500 ft., in December. Mr. M. O. 

 Pasco also met with it commonly on Ben Lomond in the same month. 

 Probably the species is distributed throughout the Wakatipu region. 



Porina aurimaculata sp. nov. 



cj. 70 mm. Head and thorax dark brown. Antennae reddish, strongly 

 bipectinate. Abdomen ochreous - fuscous. Forewings elongate, termen 

 strongly oblique ; bright brown tinged with ochreous and suffused with 

 darker on basal half of costa ; an irregular dark-fuscous blotch on dorsum 

 at base ; a similar blotch beyond this, irregularly margined with white ; 

 a large broadly oval, dark-fuscous spot below middle at £, touching similar 

 spot obliquely beyond, irregularly white-margined ; several white, or dark 

 fuscous margined with white, spots in disc ; some bent linear whitish marks 

 on costa at | ; a double series of irregular dark -fuscous spots parallel with 

 termen, more or less white-margined, and those toivards middle golden- 

 centred ; a terminal series of small white-margined fuscous spots : cilia 

 ochreous, barred with dark fuscous, tips somewhat whitish. Hindwings 

 ochreous-brown : cilia as in forewings. 



This magnificent species differs from all the other members of the genus, 

 except P. dinodes, in the strongly bipectinated antennae of the £. From 

 P. dinodes it can be separated by the narrower wings and the golden-centred 

 spots. The pectinations of the antennae are also slightly shorter in P. auri- 

 >naculata. 



The Hermitage, Mount Cook. A single specimen taken at light on 

 the 28th March by Mr. F. S. Oliver.
