1. Dichelia, Gn. 



Thorax smooth (rarely crested). Antennae shortly ciliated in male. 

 Palpi rather short, porrected, densely rough-scaled above and generally 

 beneath, often tufted beneath. Forewings with costa simple in male. 

 Hindwings hardly broader than forewings. Forewings with 12 veins, 7 and 

 8 stalked, 7 to hindmargin. Hindwings with 8 veins, 3 and 4 from a 

 point or stalked, 5 approximated to 4 at base, 6 and 7 stalked. 



Immediately distinguished from the other genera with veins 7 and 8 of 

 the forewings stalked, by the absence of the costal fold in male. Only one 

 New Zealand species is known, but the genus is well represented in Australia. 



1. Dich. luciplagana, Walk. 

 (Padisca luciplagana, Walk., Brit. Mus. Cat., 381; (Dichelia), Meyr., Proc. Linn. Soc. 



N.S.W., 1881, 470.) 



Media, alis ant. dilutissime ochreis, triangulo costse magno saturate 

 fusco, spatio incluso semiovali saspius albo, macula marginis postici elongata 

 ciliisque saturate fuscis ; post, albidis, apice leviter ochreo. 



Male, female. — 18-19^- mm. Head and thorax whitish-ochreous. Fore- 

 wings moderate, posteriorly dilated, costa arched towards base, faintly 

 sinuate in middle, hindmargin sinuate, oblique ; whitish-ochreous, finely 

 strigulated and sometimes suffused with darker ; a moderately broad dark 

 reddish-fuscous outwardly oblique streak from costa at J, and a similar 

 inwardly oblique streak from costa at § , uniting on disc below middle so as 

 to form a triangle enclosing a semi-oval white or pale ochreous patch ; a
