DESCRIPTIONS OP TWO NEW SPECIES OF HEPIALIDAE FROM 

 NEW ZEALAND. 



BY G. V. HUDSON, P.E.S., F. X.Z.INST. 



P or ilia oreas, n. sp. 



The expansion of the wing's of tlie male is If inches ; of the female nearly 

 L' inches. The fore-wings of the male are chocoUtte-hrown, timjcd loith rt-ddisli 

 tmoards the dorsum, loith a whitish patch in the middle of the basal area ; there 

 is a very thick wavy black streak at the base below the middle, reachiny about 

 one-third the ktigth of the dorsum ; this is margined with ivhite toioards the disc ; 

 seven blickish-edged white spots are situated on the co-ital area; a small one 

 on the costa at the base, two large ones above the disc before the middle, one 

 each between veins 9 and 10 and 8 and 9, and two between veins 7 and 8 5 

 there is a series of subterminal dusky marks between the veins, one or two 

 white centred, and a cloudy band inside these. In the female the ground- 

 colour of the fore-wings is redder with reddish patches around all the principal 

 markings, which are very much smaller and less distinct than in the male. 

 The hind-wings in botli sexes are brownisli-grey and semi-transparent. The 

 cilia of both wings are browuisb-ochreous irregularly barred witli brown. 



This fine species was discovered bj^ Miss Averil Ly.saght on 

 Mount Egmont, in December, at an altitude of" about 3000 feet above 

 sea-level. 



Porina autiimnata, n. sp. 



The expansion of the wings is ] f inches. The fore- winys are rich chocolule- 

 brown with clear white and golden-ochreous-broicn markings, but no distinct 

 central streak; there is a rather elongate irregular white spot at the ori^-ius of 

 veins 7, 8, and 9 ; six minute white marks between the same veins towards the 

 termen ; a large curved mark at the origins of veins 4, 5, and 6, and three 

 wedge-shaped marks beyond this ; there are several curved marks between 

 veins 2, 3, and 4 near origin, and a terminal series of cuived white marks 

 between veins 2 to 8 inclusive ; below the middle of the wing most of tlie 

 white markings are broadly edged with golden-ochreous-brown. The hind- 

 wings are pale brown, semi-transparent, with the veins much darker. The 

 cilia of both wings are chocolate-brown barred with goldeu-ochieous-brown. 

 The top of the head and the antennae are ochreous. 



Described from a single specimen captured by Mr. F. de J. Clere in 

 May at his residence in the Hutt Valley near Wellington. A second 

 specimen was afterwards caught h}- Master Peter Field in tlie same 

 locality. This species is evidently on the wing very mucli later in tlie 

 season than any of our other Porinas.
