Meyrick. — Xotes on New Zealand Geometrina. 49 



Islands ; the genus is not yet known elsewhere. The character 

 of the ciliation of the antennae in the male separates the genus 

 into three well-marked natural sections : one Australian and the 

 Tongan species belong to section B ; the other Australian species 

 belong to section C. In all the New Zealand species, vein 6 of 

 the forewings rises from a point with or near below 9 (varying 

 to this extent within the same species) ; veins 3 and 4 of the 

 hindwings are remote and tolerably parallel ; G and 7, stalked.

§ A. Antenna? of male with long fasciculated ciliations (3-4). 



Pas. plinthina, n. sp. 

 Male. — 19 mm. Head, thorax, and abdomen whitish- 

 ochreous, irrorated with reddish. Palpi 3, whitish-ochreous, 

 towards base blackish beneath. Antennae whitish-ochreous, 

 spotted with fuscous above, ciliations 4. Legs blackish, apex 

 of joints ochreous-whitish, posterior pair wholly pale whitish- 

 ochreous. Forewings with hindmai-gin very oblique, somewhat 

 bowed, slightly sinuate above anal angle ; whitish-ochreous, 

 suffusedly irrorated with reddish, tending to form very obscure 

 lines ; a blackish irroration towards costa on basal fourth ; edge 

 of median band marked by series of black dots on veins, anterior 

 from | of costa to f of inner margin, curved, posterior from 

 before f of costa to § of inner margin, upper f tolerably regularly 

 curved ; a pale waved subterminal line preceded by a reddish 

 fascia, forming a darker red spot above middle, another above 

 anal angle, and a blackish costal spot ; a black hindmarginal 

 line : cilia ochreous-whitish, with an obscure reddish line, basal 

 half with reddish-fuscous spots on veins. Hindwings with hind- 

 margin unevenly rounded, upper half rather deeply sinuate ; 

 pale whitish-ochreous, with obscure waved reddish lines except 

 towards costa ; a conspicuous black discal dot before middle ; 

 posterior edge of median band and a subterminal line more 

 strongly marked ; a blackish hindmarginal line ; cilia as in 

 forewings.
