Apparently indicates the connection of the genus with Zacorisca , 
but exhibits the singular 3 peculiarities of lieuration fully deve¬ 
loped and unexplained. 
ZACORISCA, Meyr. 
I find that Megnlocloris cannot be maintained as distinct from 
this; veins 0 and 7 of hindwings are usually closely approximated 
at base, seldom short-stalked, but this is not constant- specifically. 
The species are therefore all transferred to Zacorisca , and form a 
single natural genus, remarkable for its bright and conspicuous 
colouring, and for the curious enlarged vesicular formation of the 
2 genitalia in all the species ; it is characteristic of the Papuan 
subregion. 
Zacorisca pliaeoxesta, n. sp. 
3 $ . 30-34 mm. Head, palpi, thorax, abdomen deep blue, 
in 3 two pale ochreous dots behind antennae,anal segment ochreous- 
whitish. Antennae 3 rather thickened with scales on back at 
about i. Forewings suboblong, costa gently arched, in 3 with 
short broad fold on basal fifth, termen rounded, somewhat oblique ; 
3 brownish-grey, 2 greyish-ochreous or brownish-ochreous ; a 
short dark blue mark on base of dorsum ; a broad whitish-yellow 
or ochreous-white costal streak from base finely attenuated to ; 
termen 3 slenderly suffused coppery-fuscous, in New Guinea § 
more broadly, in Ceram 2 hardly perceptibly : cilia 3 light glossy 
grey, 2 light greyish-ochreous. Hindrvings dark brown-grey, 
browner posteriorly ; cilia 3 whitish-grey, a dark grey subbasal 
line, ^ pale greyish-ochreous.
