Meyrick. — On New Zealand Micro-Lepidoptera. 27 



to anal angle ; a white dot in disc at J, a second hardly beyond middle, 

 and a third somewhat larger on fold between these ; a row of whitish- 

 ochreous dots along hindmargin and apical fourth of costa : cilia dark 

 fuscous. Hindwings dark fuscous ; cilia fuscous, with a darker basal line. 



The conspicuous white discal dots afford an easy point of recognition. 



Dunedin, in January ; one specimen received from Mr, A. Purdie. 

 11. Thamnosaea, n. g. 



Head with appressed scales, sidetufts moderate, loosely spreading. 

 Antennas in male moderate, biserrate, moderately and evenly ciliated (1), 

 basal joint rather long, without pecten. Palpi moderate, second joint not 

 exceeding base of antennas, densely scaled, beneath with long projecting 

 hairscales, forming a large square tuft, terminal joint slightly shorter than 

 second, slender, curved. Thorax smooth. Forewings moderate, apex 

 rounded, hindmargin oblique. Hindwings as broad as forewings, elongate - 

 ovate, hindmargin rounded, cilia -f . Abdomen moderate. Posterior tibial 

 shortly rough-haired above. Forewings with vein 7 to costa, 2 from rather 

 before angle of cell. Hindwings normal. 



Allied to Gymnobathra, of which it is probably a development ; differs 

 from all New Zealand genera except Aochleta in the tuft of the second joint 

 of palpi ; but in Auchleta the tuft is much less developed. Vein 2 of the fore- 

 wings is widely remote from the angle of the cell ; and veins 3 and 4 of the 

 hindwings are stalked. Only one species is known, peculiar to New Zealand. 

 25. Thamn. chirista, n. sp. 



Minor, alis ant. albido-fuscis, saturate fusco creberrime irroratis ; post, 

 griseis. 



Male, female. — 13-14 mm. Head, palpi, antennas, and thorax fuscous- 

 grey ; terminal joint of palpi grey-whitish, anterior edge dark fuscous. 

 Abdomen grey, anal tuft pale greyish-ochreous. Legs dark fuscous ; pos- 

 terior tibiae and apex of all tarsal joints whitish. Forewings moderate, 

 costa moderately arched, apex rounded, hindmargin very obliquely rounded ; 

 whitish fuscous, very densely and finely irrorated with dark fuscous ; a few 

 scattered black scales : cilia whitish fuscous, on lower half densely irrorated 

 with dark fuscous. Hindwings grey, somewhat darker towards apex ; cilia 

 whitish-grey, with a darker line near base. 



A very dull-coloured and inconspicuous insect. 



Christchurch, in December ; three specimens amongst bush, in indif- 

 ferent condition. 



12. Gymnobathra, Meyr. 



Head loosely scaled, sidetufts large, appressed, projecting over fore- 

 head. Antennas in male moderate, moderately and evenly ciliated (1), 

 basal joint rather elongate, moderate, without pecten. Palpi moderate,
