74 SUBANTARCTIC ISLANDS OP NEW ZEALAND. [Lcpidoptcra. 



and posteriorly expanded into a triangular blotch whose base is connected with costa 

 by three very short arms, and apex connected by a striga with termen below middle ; 

 dorsal edge mostly blackish ; two dots on costa beyond central fascia, and some 

 irregular strigulae along termen : cilia light yellow-ochreous, basal half barred with 

 blackish. Hindwings ochreous-whitish ; a suffused streak of grey strigulae along 

 posterior part of median fold, and a streak of grey strigulae beneath vein 2 : cilia 

 whitish-ochreous, basal third blackish-grey. 



Auckland Island ; one specimen, bred from larva feeding in Hower-heads of 

 Pleurofhylluni speciosum. 



Allied to astrologana, Meyr., but distinct by form of wing anil markings. 



Phaloniadae. 

 Heterocrossa gonosemana, Meyr. 



Carnley Harbour, Auckland Island ; two specimens (male and female). 



These are more irrorated with grey and a few black scales than my Dunedin 

 specimens, but hardly more than some from Wellington ; the black spot on base of 

 costa is more obviously triangular ; but after close comparison I am unable to regard 

 them as distinct. 



TiNEIDAE. 



Proterodesma, ii. g. 



Head densely rough- haired ; ocelli and tongue absent. Antennae 1, in male ? 

 Labial palpi, long, curved, ascending, second joint beneath rough-scaled and with 

 numerous projecting bristles, terminal joint moderately long, slender, obtuse. 

 Maxillary palpi long, filiform, folded. Posterior tibiae clothed with hairs above. 

 Forewings with lb furcate, 2 from towards angle, 7 to costa, 1 1 from J of cell, widely 

 remote from 10, 8-11 becoming obsolete near costa and connected by a more or less 

 developed subcostal bar, most distinct between 10 and 11. Hindwings i, ovate- 

 lanceolate, cilia f ; 2-7 separate, tolerably parallel, 6 to costa. 



A peculiar form, probably related to Tinea terranea, Butl., but the exceptional 

 structure of the costal veins is analogous to that found in TrichopJiagn. 



Proterodesma byrsopola, n. sp. 



I . 20-22 mm. Head pale ochreous, with some dark-fuscous liairs. Palpi 

 and antennae pale ochreous. Thorax pale ochreous, shoulders suffused with fuscous. 

 Abdomen pale greyish-ochreous, more or less inluscated. Forewings elongate, rather 

 narrow, costa moderately arched, apex round-pointed, termen extremely obliquely 

 rounded ; whitish-ochreous tinged with brownish and more or less mixed with 

 fuscous ; an undefined blackish streak in disc from before middle to f . appearing 

 to be terminated by indications of pale spots ; a strong blackish streak along fold 

 from near base to near tornus, interrupted by two whitish-ochreous spots second more 

 elongate : cilia whitish-ochreous. Hindwings light purplish-bronzy-grey, paler and 

 tinged with wliitish-ochreous towards base, margin towards apex suffused with 

 wliitish-ochreous ; cilia whitish-ochreous. 



Carnley Harbour and Norman Inlet, Auckland Island ; three specimens. 



In one of these, in one hindwing only, vein 6 is long-furcate, botli branches 

 terminating in the costa, so that there aj^pears to be an additional vein, an uncommon 

 abnormality which deserves record when noticed.
