174 FAUNA HAWAIIENSIS 



reddish-ochreous or reddish-ochreous-brown, strigulated with dark fuscous, in % whitish- 

 ochreous irrorated with dark fuscous ; first Hne curved, in ^ partially marked with dark 

 fuscous, in $ with three dark fuscous dots ; median more or less dark, curved outwards 

 on upper half ; a transverse-oval fuscous discal spot before median, sometimes obsolete ; 

 second line waved, in ^ more or less dark-marked, in % dotted with dark fuscous, curved 

 outwards on upper |, nearly approximated to median on lower third, space between 

 these sometimes suffused with dark fuscous in middle and on dorsum ; subterminal 

 faintly indicated; sometimes an oblique dark subapical streak. Hindwings with termen 

 waved ; colour and lines as in forewings, but first line obsolete, median and second not 

 much approximated dorsally. 



4 specimens ; 3 near Honolulu, Oahu, at 2000 feet ; i Pauoa Valley, Oahu, at 1 500 

 feet ; in March, April, and October. This species, isospora, aruraea, and probably 

 corticea, are closely related together, and may be regarded as representative forms of a 

 common stock, each being confined to a different island. This species is particularly 

 distinguished by the dorsal approximation of the median and second lines of forewings ; 

 it is also the smallest in averag-e size.

(4) Scotorythra epicyma, sp. nov. 



$. 43 mm. Head and thorax light ferruginous-brown. Antennae pale brownish- 

 ochreous. Abdomen brownish-ochreous, sprinkled with dark fuscous. Forewings 

 rather elongate-triangular, apex slightly prominent, termen somewhat bowed, little 

 oblique ; ferruginous-brown, slightly sprinkled with blackish ; first, median, second, and 

 praesubterminal thick cloudy dark fuscous shades, three former rather near together, 

 first and second waved, hardly curved, not reaching costa, median and praesub- 

 terminal almost straight, entire, but latter faint at tornus ; a cloudy dark fuscous 

 terminal patch beneath apex. Hindwings with termen hardly waved ; colour, median, 

 second, and praesubterminal shades, connecting blotch, and subapical suffusion as in 

 forewings. 



I specimen, Kaholuamano, Kauai, at 4000 feet, in April. Evidently allied to the 

 isospora group, but distinguished from them all by the straighter lines, larger size, and 

 hardly waved termen of hindwings ; the dark suffusion of the markings is probably 

 variable as in the allied species.

%. 35 mm. Head, thorax, and abdomen brownish, segmental margins finely 

 whitish. Antennae ochreous-whitish, hardly ringed. Forewings rather elongate-
