STUDIES IN AUSTRALIAN LEPIDOPTERA. H$ 
white. Abdomen whitish. Legs whitish ; anterior and middle pairs 
with some fuscous suffusion. Forewings elongate, costa slightly 
arched, apex round-pointed, termen scarcely oblique, rounded 
beneath ; shining white ; well-marked costal and dorsal fuscous- 
brown streaks ; cilia white, at apex and tornus fuscous-brown. 
HindwinLrs with termen rounded ; white ; cilia white. Underside 
dull-white. 
Type in Coll. Turner. 
N.A. -Port Darwin, in December and February ; two specimens 
received from Mr. F. P. Dodd. 
Gen. DIADEXIA. 
I was wrong in describing vein 6 of hindwings as arising from 
the upper angle of the cell (P.B.S.Q. 1905, p. 56). It arises well 
below the angle as in Talis, of which this genus is a derivative. I 
believe Diadexia pa^odes is the same species as Surattha hrunnea, 
Hmps., which I have not seen described. 
DIABEXIA ARGrYHOPASTA n. sp. 
[apyvpoTracrTos, silver-sprinkled.] 
9. 13-15 mm. Head and thorax brown. Palpi long (I|) ; 
brown, towards apex suffused with fuscous. Antennae dark- fuscous 
finely annulated with white ; in $ evenly bipectinate, apical \ 
simple, pectinations L Abdomen fuscous. Legs fuscous; posterior 
pair ochreous-whitish. Forewings elongate, costa gently arched, 
apex rounded, termen straight, slightly oblique ; brown, towards 
apex suffused with fuscous ; a short silvery median streak from 
base ; costal narrowly whitish to f, where is a white spot with some 
silvery scales ; a circular white subcostal spot at -§-, connected with 
dorsum by some silvery scales ; sometimes connected with costa by 
a whitish streak ; a silvery white spot on dorsum at f succeeded by 
a blackish suffusion ; a white dot on costa at f from which proceeds 
a silvery line at first outwards, then parallel with termen to before 
tornus ; cilia silvery-white with a fuscous median line beneath apex. 
Hindwings with termen rounded ; dark-grey ; cilia grey. 
Agrees with Diadexia in neuration, though not near specifically, 
and with different $ antennae. 
N.A. Port Darwin, in October and November ; four specimens 
received from Mr. F. P. Dodd.
