having the antennae of <$ shortly pubescent-ciliated, whilst in S. marmarea, 

 which is also very similar superficially, they are ciliated with long 

 fascicles (3), as is usual in the genus. S. ministra differs from the 

 other two in having the antennae wholly dark fuscous, the forewings 

 obviously broader anteriorly, with costa more arched than in either of 

 the others, the white markings of forewings less defined, the white 

 streak of hindwings broader and more irregular, reaching termen at 

 | from apex and continued almost to tornus. 



Simaethis microlitha Meyr. 



cJ $. 9-10 mm. Head and thorax irrorated with white above ; scales 

 of palpi longer and more projecting than in analoga ; antennae dotted 

 witli white : abdomen with segmental margins strongly white. Fore- 

 wings more narrowed towards base than in ministra, fasciae of white irro- 

 ration more strongly marked, fourth slender, but more sharply marked 

 and brightly silvery-metallic above discal mark and at apex of dorsal 

 section. Hindwings with white streak slender, regular, well-marked, ex- 

 tending | across wing from f of disc to middle of termen and thence 

 running partially interrupted near termen almost to tornus. 



Arthur's Pass, 3,000 ft., in January ; two specimens. In my descrip- 

 tion of this species I included also the following, which I now separate 

 from it, and therefore specify the more characteristic points which dis- 

 tinguish the true microlitha from the preceding and following species ; 

 the character of the marking of hindwings is the most obvious of these. 



Simaethis analoga n. sp. 



c?$ . 8-9 mm. Head dark fuscous, face and sides of crown irrorated 

 with white. Palpi with whorls of dark-fuscous white-tipped scales, base 

 white. Antennae dark fuscous dotted with white, in cJ shortly pubescent- 

 ciliated. Thorax dark fuscous, somewhat sprinkled with white, inner 

 edge of patagia white. Abdomen dark fuscous, segmental margins strongly 

 white. Forewings rather elongate-triangular, costa gently arched, apex 

 obtuse, termen slightly rounded, somewhat oblique ; dark bronzy-fuscous ; 

 three curved cloudy transverse lines of white irroration on anterior half, 

 two posterior sometimes irregularly confluent ; a white line beyond middle 

 forming a quadrangular loop behind a transverse-linear white discal mark, 

 upper side of loop silvery-metallic, lower absent, a silvery-metallic dot 

 on upper extremity of dorsal segment ; a straight cloudy line of white 

 irroration from f of costa to tornus, interrupted above middle ; a trans- 

 verse silvery-metallic mark before termen above middle : cilia white with 

 two thick dark-fuscous lines, and dark patches at apex, middle of termen, 

 and tornus. Hindwings fuscous, becoming dark fuscous posteriorly ; a 

 very short white detached transverse mark before middle of termen, and 

 sometimes a dot on tornus ; cilia white, with two thick dark-fuscous lines. 



Mount Arthur, 4,000 ft., in January ; ten specimens. As explained 

 above, I originally regarded this as a form of microlitha, but now think 

 it distinct. Doubtless more species of this group will be discovered in 

 the mountains, and an attempt should be made to ascertain their food- 

 plants. 



Ereunetis acrodina n. sp. 



$. 14 mm. Head whitish-ochreous, hairs of forehead slightly mixed 

 with dark fuscous. Antennae grey-whitish, basal joint with a blackish
