fuscous, median ring of tibia? and apex of all joints whitish-ochreous. Fore- 

 wings moderate, costa gently arched, apex rounded, hindmargin oblique, 

 hardly rounded ; dull fuscous, mixed with darker and lighter ; the lighter 

 tint appears to form an obscure transverse fascia before middle parallel to 

 hindmargin, and a curved transverse line from f of costa to before anal 

 augle ; a tuft of dark fuscous scales beneath fold at ^ ; an arched dark 

 fuscous mark in disc beyond middle ; hindmargin and apical fourth of costa 

 obscurely spotted with darker : cilia fuscous, with a darker line. Hindwings 

 dark fuscous, somewhat lighter towards base ; cilia fuscous, with a cloudy 

 darker line. 



Conspicuously distinct by its deep fuscous colouring. 



Wellington, in January ; two specimens. 



10. Lathicrossa, n. g. 



Head with appressed scales, sidetufts moderate, loosely spreading. 

 Antenna? in male moderate, strongly serrate towards apex, very shortly 

 ciliated (J), basal joint moderate, without pecten. Palpi moderately long, 

 second joint not exceeding base of antenna?, thickened with dense appressed 

 scales, terminal joint as long as second, rather stout, curved. Thorax 

 crested posteriorly. Forewings moderate, apex obtuse, hindmargin oblique. 

 Hindwings as broad as forewings, trapezoidal, hindmargin slightly sinuate, 

 cilia f. Abdomen moderate. Posterior tibia? with short rough hairs above. 

 Forewings with vein 7 to costa, 2 from rather before angle of cell. Hind- 

 wings normal. 



Allied to Gymnobathra, from which it is distinguished by the very short 

 ciliations of the antenna?, and the thoracic crest. The single species is 

 confined to New Zealand. 



24. Lath, leucocentra, n. sp. 



Minor, alis ant. saturate fuscis, maculis costa? duabus parvis serieque 

 punctorum marginis postici albido-ochreis, punctis disci tribus niveis; post, 

 saturate fuscis. 



Male. — 15 mm. Head whitish-ochreous, suffused on crown and fore- 

 head with dark fuscous. Palpi whitish-ochreous, externally sprinkled with 

 dark fuscous, anterior edge marked throughout by a slender dark fuscous 

 line. Antenna? dark fuscous. Thorax and abdomen dark fuscous, with a 

 few whitish-ochreous scales. Legs dark fuscous, central ring of tibia?, hairs 

 of posterior tibia?, and apex of all joints whitish-ochreous. Forewings 

 moderate, somewhat dilated, costa gently arched, apex obtuse, hindmargin 

 oblique, almost straight, very faintly sinuate beneath apex ; dark fuscous, 

 with irregularly scattered whitish-ochreous scales ; a very small whitish- 

 ochreous spot on middle of costa, and a rather larger transverse spot on 

 costa at f , giving rise to a very faint curved line of whitish-ochreous scales
