1068 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, 



A conspicuously distinct and elegant species. 



Larva feeds in a portable case on Eucalyptus hemiphloia, eating 

 holes in the leaves ; case formed of a single stout cylindrical 

 twig, hollowed down the centre and open at both ends ; found in 

 November. This kind of case (shared at least by the following 

 species and probably others) is not known to me as employed in 

 any other genus of Lepidoptera. 



Sydney, New South Wales ; one specimen bred in December. 



373. Ocyst. tyranna, n. sp. 



Media, alis ant. griseis, albido-conspersis, serie obliqua antica 

 macularum trium parvarum lutearum, punctis disci duobus lineaque 

 postica obscuris saturatioribus, ciliis flavis ; post, dilutius ochreo- 

 flavis. 



Q. 23 mm. Head and thorax light grey. Palpi grey-whitish, 

 reddish-tinged, anteriorly greyer, terminal joint very short, ^ of 

 second. Antennae grey-whitish. Abdomen light yellow-ochreous. 

 Legs light grey, crimson-tinged, posterior pair light yellow-ochreous. 

 Fore wings elongate, moderate, costa rather strongly arched, apex 

 round-pointed, hindmargin sinuate, rather oblique ; clear grey, 

 densely irrorated with whitish hair-scales except towards base and 

 on margins ; three small round pale whitish-ochreous spots arranged 

 in an inwardly oblique row from beneath | of costa to above inner 

 margin near base ; two indistinct grey dots in disc before and after 

 middle ; a faint roundish pale whitish-ochreous spot above middle 

 of inner margin ; an indistinct irregular grey line from | of costa 

 to anal angle ; a dark grey hindrnarginal line : cilia ochreous-yellow, 

 becoming light reddish-purple towards base, on anal angle broadly 

 grey. Hindwings elongate-ovate, round-pointed, veins 3 and 4 

 slightly remote ; light ochreous-yellow, extreme apex grey ; cilia 

 pale ochreous-yellow, on an apical spot and between middle of 

 hindmargin and anal angle light grey. 



Certainly allied to the preceding but very different : the terminal 

 joint of palpi is relatively much shorter than in any other species 

 of the genus.
