Meyrick. — Descriptions of New Zealand Lepidoptera. 29 



tibiae shortly rough-scaled. Forewings with cell very long, 2-4 short, 

 2 tolerably remote from angle, 3 from angle, 7 to costa, 11 from much 

 before middle. Hindwings under 1, narrowly elongate-ovate, cilia 1 ; 2-4 

 remote, 5 and 6 short-stalked, approximated to 7 at base. 



Allied to Tinea, but characterized by the peculiar maxillary palpi. 



Thallostoma eurygrapha n. sp. 



S $• 18-19 mm. Head and palpi ochreous-whitish, palpi externally 

 blackish except towards apex. Thorax dark fuscous, patagia whitish except 

 shoulders. Forewings elongate, narrow, costa gently arched, apex obtuse- 

 pointed, termen very obliquely rounded ; dark purplish-fuscous ; markings 

 pale whitish-ochreous ; a rather broad irregular streak along dorsum and 

 termen throughout, just reaching costa at base, triangularly prominent up- 

 wards before middle of wing, narrowed to a point at tornus, thence expanded 

 to apex ; a semioval blotch extending on costa from before middle to near |, 

 and reaching nearly half across wing : cilia pale whitish-ochreous. Hind- 

 wings grey ; cilia ochreous-whitish. 



Wadestown, in November (Hudson) ; two specimens, both damaged. 



Trithamnora n. g. 



Head with deilse rough projecting scales ; ocelli absent ; tongue absent. 

 Antennae f, in cj ciliated, basal joint moderate, stout, with slight pecten. 

 Labial palpi moderate, porrected, stout, considerably expanded with dense 

 rough scales projecting beneath, second joint with a few short lateral bristles, 

 terminal joint short, obtuse. Maxillary palpi moderately long, slender, 

 filiform, drooping. Posterior tibiae clothed with long hairs above and 

 beneath. Forewings with subdorsal tufts of raised scales ; cell long. 2 

 tolerably remote from angle, 3 from angle, 7 to costa, sometimes stalked 

 with 8, 11 from \. Hindwings 1, elongate-ovate, cilia f ; 2-4 remote, 

 5 and 6 approximated towards base, 7 nearly parallel. 



Trithamnora improba n. sp. 



<S. 16 mm. Head and antennae fuscous. Palpi dark fuscous mixed 

 with black, apex of joints pale ochreous. Thorax dark purplish-fuscous. 

 Abdomen dark fuscous. Forewings elongate, narrow, costa gently arched, 

 apex tolerably pointed, termen very obliquely rounded ; dark purplish- 

 fuscous, sprinkled with blackish scales and whitish specks, dorsal and ter- 

 minal areas lighter ; a series of four raised tufts of rough pale greyish- 

 ochreous scales beneath fold : cilia dark fuscous sprinkled with ochreous- 

 whitish, beneath tornus with a patch of whitish-ochreous suffusion. Hind- 

 wings dark purplish-fuscous, lighter anteriorly ; cilia fuscous, with dark 

 fuscous subbasal line. 



Wellington (Hudson) ; two specimens. Easily confused with dark forms 

 of Tinea certella, and therefore probably hitherto overlooked ; it may, 

 however, be immediately distinguished by the subdorsal tufts of scales. 

 It is likely that the larva would feed in dead wood, and the imago be found 

 on the trunks in dark forests.
