This species differs in the ^ from kebea, R. -Baker, with 

 which it has hitherto been confused, in the longer palpus 

 (l^ diameter of eye in kebea, twice diameter of eye in 

 oivgarra) ; in the rather smaller size (36 mm. in owgarra, 

 40 mm. in kebea) ; in the broad white subcostal area along 

 SC-SC^ nearly to apex (in kebea the antemedial green and 

 brown shading extends broadly to middle of wing fi'om costa 

 to hind margin) ; in the absence of the white tooth between 

 the apical dark patch and the dark mark behind SC (which 

 in owgarra is merely a diffused purple-grey shade) ; in the 

 reduced and more oblique basal white shade, which in 

 owgarra starts from the base of SC (with narrow white line 

 before it from base of costa) and is crenulate to about two- 

 fifths hind margin, while in kebea it starts from costa and is 

 almost straight to two-fifths hind margin ; the white band 

 proximally to [)Ostraedial line is less straight and regular in 

 owgarrai\\?iX\ in kehea, the postmedial line rather more curved 

 and less dentate ; the white marginal lunule behind M^ is 

 much smaller in owgarra than in kebea. Hind wing with 

 the dark bordering reduced and almost without the black 

 postmedial spots on veins. 



In the ? there is a similar difference in size (36-38 mm. 

 in oivgarra, 44 mm. in kebea) ; the white basal patch is- 

 reduced and has the edge crenulate, as in the ^ , the type 

 $ of kebea being without any dark shading on the white 

 patch, whilst all ? ? of owgarra yet studied have all but a 

 narrow line at distal edge shaded with green marked with 

 brown ; the pale postmedial costal patch extends to a point 

 on M^ in owgarra (in kebea it is intercepted by a violet shade 

 on R^) ; the difference in the apical patch is as in the ^ , but 

 the dark mark behind SC is enlarged and very black in 

 the ? of kebea ; in kebea ? the postmedial line is inwardly- 

 oblique from R^ to hind margin about 2^ mm. from ante- 

 medial line, in owgarra the two lines are about 5 mm. apart 

 on hind margin. 



The description of cebea (in Cat. Lep. Phal. xi.) seems to- 

 embrace some of the salient points of each species, the ? in,
