and on veins, all parallel; a small blackish discal dot; a cloudy blackish 
line beyond middle, dilated on costa, preceded by a fainter line, and bordered 
posteriorly by a white line, central third forming a broad bidentate projec- 
tion; an indistinct whitish dentate subterminal line, preceded by a dark 
fuscous shade. Hindwings rather elongate, hindmargin rounded; deep 
ochreous-yellow, base mixed with dark fuscous; an angulated median line, 
an irregular subterminal fascia, and hindmargin dark fuscous. Forewings 
beneath yellow, with two blackish posterior streaks from costa, and a 
reddish spot beneath apex ; hindwings beneath reddish, disc longitudinally 
whitish, with irregular median and subterminal blackish bands. 
Constant; it would be interesting to know the cause of the beautiful 
colouring of the under-surface, which is probably protective. 
Mr. R. W. Fereday found this species common in the grassy bed of a 
dry lagoon near Lake Guyon, in February and March; I beat a specimen 
from bush in the Otira Gorge, at 1,800 feet, in January. Twenty 
specimens.
