292 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, XVIII., 



shoulders and a dorsal stripe fuscous. Abdomen greyish- 

 ochreous. Legs dark fuscous ringed with ochreous-whitish. 

 Fore wings pointed; 6 separate; whitish-ochreous, irregularly mixed 

 with ochreous and somewhat sprinkled with dark fuscous; costal 

 edge whitish, irregularly spotted with dark fuscous, with larger 

 cloudy spots at f and 4; a small dark fuscous spot on dorsum 

 near base, and one on fold at i; a fuscous dark-edged somewhat 

 reniform blotch on dorsum before middle, reaching | across wing, 

 pointed above; second discal stigma dark fuscous : cilia whitish- 

 ochreous, basal half more ochreous. Hind wings grey, lighter 

 towards base; cilia light greyish-ochreous. 



Broken Hill, New South Wales; Geraldton, West Australia; 

 in October, three specimens (including Mr. Lower's type). 



8. Thiotricha, Meyr. 



Antenna 4, in ^ strongly ciliated (3-5), basal joint elongate, 

 without pecten. Labial palpi long, recurved, second joint smooth- 

 scaled, terminal joint as long as or longer than second, acute. 

 Fore wings : 2 and 3 separate, 4 absent, 7 out of 6, running to 

 costa, 8 absent, 9 out of 6 or approximated. Hind wings under 

 1, elongate-trapezoidal, apex acute, more or less produced, termen 

 more or less emarginate, cilia 2-6; 3 and 4 connate, 5 rather 

 approximated to 4, 6 and 7 stalked. 



Type T. thoryhodes, Meyr., from New Zealand. This genus, at 

 present known only from Australia and New Zealand, is well 

 characterised by the long antennal ciliations of (J, and absence 

 of veins 4 and 8 of forewings (I formerly regarded 2 as the lower 

 absent vein, but now think it to be more probably 4); in the 

 narrower-winged species 9 rises from 6, whilst in one New Zealand 

 species (probably the most ancestral form) 6, 7, and 9 are all 

 separate, but I do not consider these differences call for generic 

 subdivision, the species being all evidently allied together. The 

 genus seems to be probabl}^ a derivative of the Dectobathra 

 group. Imago with forewings elongate, pointed. The only larva 

 known lives in a portable case and mines blotches in leaves, in 

 the manner of Coleophora.
