b. Lines ochreous-ycUow. 



1. Discal spot of fore wings sharply triangular, 

 blackish . . . . . . . . . . . . cassalis. 



2. Discal spot of fore wings yellow, or with a few 



dark fuscous scales . . . . . . . . . . chrymplasta. 



A. Antennae of male ciliated with tufts of cilia (Ij). 



Notarcha chrysoplasta, n. s. 

 <y , ? , 22 — 23 mm. Head, palpi, antennae, thorax, abdomen, 

 and legs ochreous-yellow ; palpi with a spot on basal joint, and 

 terminal joint except apex blackish ; anterior tibiae with apical half 

 blackish, tarsi with apex of 1st joint broadly, of others very 

 narrowly blackish. Fore wings moderate, triangular, costa very 

 slightly sinuate, gently arched posteriorly, apex obtuse, hind 

 margin obliquely rounded ; light ochreous-yellow, with darker 

 ochreous-yellow markings ; two irregular lines near base ; an 

 irregular somewhat curved line from one-fourth of costa to one- 

 third of inner margin ; a small discal spot ; an irregular line from 

 costa at two-thirds to middle of inner margin, rectangularly arched 

 outwards in middle and returning to beneath discal spot ; a 

 suffused subterminal band, contracted or interrupted a little above 

 inner margin ; sometimes three minute blackish subcostal dots 

 near base, at one-fourth, and two-thirds, and also one on discal 

 spot, but these are often wholly absent ; cilia with basal half 

 ochreous-yellow, apical half whitish yellow. Hind wings with 

 ground colour and markings as in fore wings, but two basal lines 

 absent, no black dots, subterminal band tinged with fuscous-grey ; 

 cilia as in fore wings. 



Belongs to the same group of closely allied species as 

 N. cassalis, Walk,, and N. trifjalis, Ld. ; distinguished 

 from the rest hy the usual ohsolescence of the blackish 

 dots. Compared with N. cassalis it is larger, the ground 

 colour yellower and markings less defined, and the sub- 

 terminal band of hind wings is distinctly tinged with 

 grey. 



Duaringa, Queensland ; four specimens received from 

 Mr. G. Barnard. 



Notarcha cassalis, Walk. 



Zehronia cassalis (cassiisalis), Walk., 477 ; Z. aiiro- 

 linealis, ib., 478 ; yistura ohrinusalis, ib., 549 

 (nee Ld.) ; Botysfaustalis, Ld., pi. x., 15. 



Lederer's species, figured as ohrinalis {ohrinusalis), 

 Walk., is certainly not this insect, but probably identical
