edge yellow at base; inner margin narrowly pale throughout; hindwing deep fuscous; the fringe yello¬ 
wish. Dunedin, New Zealand. A large species, expanding between 50 and 60 mm. 
I. blenheimensis Frdy. (13 h). Forewing rufous ochreous, the veins dotted fuscous and whitish; 
inner and outer lines formed of black points on the veins; a small streak at lower angle of cell; veins 
at apex slightly dark; the fringe fuscous; hindwing fuscous ochreous, darker towards termen. Blen¬ 
heim and Napier, New Zealand. 
I. sulcana Frdy. (13 h). Forewing ochreous, the costal edge fulvous; inner marginal area and 
costa towards apex with dark dusting; the veins pale; terminal intervals streaked with reddish brown; 
a black streak in base of submedian fold with rufous suffusion above it; an obscure rufous streak 
above vein 4; a black dot at base of cell; inner line marked by black points on submedian fold and 
vein 1; the outer by points on veins 6, 3, and 1; a black dot beyond lower angle of cell; hindwing deep 
brown. Akaroa, Dunedin, New Zealand. 
I. epiastra Meyr. Forewing light brownish with some scattered black specks; suffused towards 
base and costa with light greyish ochreous; inner line marked by 2 or 3 black dots, outer by a series 
of dots; at lower angle of cell two white dots placed longitudinally, connected by some grey scales; a 
terminal row of black dots between veins; hindwing fuscous, paler towards base. Larva dull brownish 
green, with narrow, pale, darker-edged lines; lateral line white, dark-edged above; head yellowish; feeds 
on the leaves of Arundo conspicua, and when fullfed pupates in a chamber formed in the flowering stem. 
Makara, New Zealand. 
I. lissoxyla Meyr. Forewing light brown; vein lb, the upper and lower margins of cell, veins 
2, 3, 4 and 6, 7, 8 with the apical third of vein 5 marked with lines of mixed blackish and whitish 
scales; slight streaks of pale ochreous suffusion beneath cell and between veins 5 and 6; fringe pale 
ochreous, tinged towards base with brown, the tips whitish; hindwing grey. Mt. Arthur tableland, New 
Zealand. Close to unica and toroneura, but distinct from both. 
I. stulta Philp. Fore wing pale fawn colour; markings dark reddish brown; a short dark

this; hindwing fuscous; fringe pale. West Plains, Tuturau, New Zealand. 
37. Genus: Klusa Walk. 
Tongue fully developed; frons smooth; palpi upturned, the second segment reaching to or above 
vertex, the third also varying, slightly porrect; thorax with slight crests; abdomen with dorsal crests 
on basal segments, the crest on third segment large; tibiae hairy; forewing with blunt apex; the 
termen curved and even; a tooth of scales at anal angle; 7, 8 stalked, 9, 10 stalked, 8 and 9 ana¬ 
stomosing, the areole long; hindwing with 6, 7 short stalked; scaling of fore wing somewhat coarse and 
heavy. Type E. ceneusalis Walk. 
A genus of small-sized species, all more or less alike, distinguished by various peculiar antennal 
and tibial developments in the <$<$, and with no close affinity to any other genera of the subfamily. 
Sect. I. Antennae of $ with basal half of shaft bipectin ate, the branches 
short, coalesce n t and contorted; a large rounded knob at middle of shaft, con¬ 
sisting of coale scent branches, hollowed out in front; the terminal third of shaft 
pectinate above, minutely serrate below towards the knob; hind tibiae of $ di¬ 
lated, fringed with very long hair behind. 
The species included in this section appear each and all liable to the same forms of variation; the 
forewing may be of uniform coloration throughout, rufous or dark brown; or the basal half may be darker 
than the outer half; or the basal half and terminal area may be dark while the intermediate space 
is pale lilac grey or dark grey; and in all these forms the reniform stigma, which normally is dark grey, may 
be snow white. 
Subsect. A. ( Elusa) Palpi of $ with second segment straight and very long, 
reaching above vertex, its extremity with a small tuft of hair in front. 
E. ceneusalis Walk. (= limacodoides Walk.) (13 h). Forewing reddish fawn colour slightly deeper 
in basal half; inner and outer lines brown, denticulated, usually indistinct; submarginal line nearly 
straight, whitish or pale, with a darker brown edge internally; orbicular stigma a whitish or pale 
point, often invisible; reniform narrow, figure of 8-shaped, much constricted or even narrowly inter¬ 
rupted in middle, the two circles filled in with leaden grey and finely outlined with pale; hindwing greyish
