larve of any Australian species, but from the habits of the 
imago, I have little doubt that all will be found to feed in the 
seed-heads of different species of grass and sedge. 
1. G. triselena, Meyrick, l.c. vol. 5, p. 234.—Head and thorax 
dark fuscous. Palpi white at base, second joint with two flat- 
tened whorls of black white-tipped scales, terminal joint black 
with two white rings. Antenne dark fuscous. Abdomen very 
long, whitish-ochreous. Legs whitish-ochreous, anterior tarsi 
with obsolete fuscous bands at the base of joints. Fore-wings 
elongate, narrowed posteriorly, hind-margin slightly indented 
below apex ; pale golden-bronze; an obscure transverse whitish 
spot on inner margin near base; three silvery-white, obscurely 
dark-margined transverse fascie ; first from 44 of costa obliquely 
outwards, angulated in middle, to inner margin before middle ; 
second and third straight, parallel, nearly perpendicular to costa, 
before and beyond middle ; from third below middle proceeds a 
rather narrow longitudinal black band, bent downwards to anal 
angle, thence continued along lower half of hind-margin, contain- 
ing 4 golden metallic spots in a row; the space between this 
and costa is filled by 6 longitudinal ochreous-whitish lines, 
partially confluent or separated by narrow black interspaces ; 2 
oblique nearly parallel silvery-white sub-apical streaks from 
costa immediately before apex to hind margin above middle, 
becoming white in the grey costal cilia ; some dark, metallic-grey 
scales at apex ; cilia whitish, basal third within a fuscous line 
closed with pale golden-bronze scales, except where a white in- 
dentation meets anterior sub-apical line. Hind-wings pale grey, 
cilia whitish-grey, Male, length 4% lines. 
Two males taken in January on the bare dry grassy volcanic 
hills near Christchurch. 
2. G. euastera, Meyrick, l.c., vol. 5, p. 236.—Head, antenna, 
and thorax dark fuscous. Palpi whitish at base, second joint 
with two whorls of dark fuscous white-tipped scales, terminal 
joints black with two white rings. Abdomen blackish-fuscous, 
beneath silvery-whitish. Legs dark fuscous, middle and poste- 
rior tibize with white central and apical rings, all tarsi with white 
rings at apex of joints. Fore-wings elongate, very slightly 
dilated, hind-margin indented beneath apex ; basal and apical 
thirds dark fuscous, densely strewn with whitish scales, central 
third bronzy-ferruginous, more or less broadly suffused with 
dark fuscous on costa and inner margin; a white oblique costal 
streak at %, reaching middle, ending in a leaden metallic spot ; 
an indistinct white spot on inner margin near base; two out- 
wardly curved steel-blue metallic fascie, ending in white spots 
on both margins, first hardly before, second beyond middle ; 
beyond these are three white spots on costa, the first two giving 
rise to obsolete metallic streaks, the last sub-apical, sending a 
steel-blue metallic streak to hind-margin below apex ; a blackish 
spot on apex ; cilia whitish, fuscous-gray at apex and anal angle, 
basal half separated by a strong dark fuscous line, and clothed 
towards base with ferruginous scales, except where a wedge-
