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

 November. This kind of case (shai-ed 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. 



9. 23 mm. Head and thorax light grey. Palpi grey-whitish, 

 reddish-tinged, anteriorly greyer, terminal joint very short, 1 of 

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

 Legs light grey, crimson-tinged, postex-ior 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 gi-ey dots in disc before and after 

 midtlle ; a faint roundish pale whitish-ochi-eous spot above middle 

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

 to anal angle ; a dark grey hindmarginal 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.
