NEW ZEALAND MICRO-LEPIDOPTERA. 33 
rather long, filiform. Labial palpi moderately long, ascending, 
arched, slender, cylindrical; second joint smooth, sometimes 
loosely scaled beneath, terminal joint nearly as long as second. 
Fore-wings elongate, very narrow, parallel-sided, costa bent at 
apex or evenly pointed. Hind-wings very narrowly lanccolate, 
much narrower than fore-wings, cilia thrice or four times as 
broad. Abdomen elongate, slender. Legs long, slender; 
middle tibia: often much thickened with scales. Fore-wings 
with 12 or II veins, 5 branches to costa, no secondary cell, I 
simple. Hind-wings with from 8 to 6 veins, 3 and 5 sometimes 
being obsolete; 5 and 6 stalked, cell open. 
All the species are elegant, and some of great beauty ; when 
at rest they sit with the forepart much raised, and the two 
anterior pairs of legs, which are often elegantly marked, con- 
spicuously displayed. ‘They are somewhat retired in habit, and 
may often be easiest found at rest on fences. 
The larvze are fourteen-legged, slender, always mining in 
leaves when young; afterwards many of the European and 
American species construct hollow cones for habitations, by 
rolling up pieces of the leaves they feed on; others remain 
miners all their life. All the Australian species, with the larve 
of which I am acquainted, are miners throughout life ; nor have 
I ever seen indications of the familiar cones of this genus in 
Australia. The mining larve usually leave the mine in order to 
form their cocoon. 
1. G. adelina, Meyrick (l.c., vol. 5, p. 142)—Head and thorax 
ochreous, reddish with violet reflections, face snow-white. 
Maxillary palpi whitish, externally ochreous, reddish. Labial 
palpi reddish-ochreous, white at base, lower half of terminal 
joint externally purple-fuscous. Antenne longer than fore- 
wings, pale reddish-ochreous, annulated with dark fuscous. 
Abdomen fuscous-grey, pale ochreous at base, beneath metallic- 
yellow. Legs pale ochreous ; anterior tibize blackish ; middle 
tibiz very much thickened, deep reddish suffused with violet 
black. Fore-wings deep reddish-ochreous with violet reflections, 
with a very broad, pale metallic-yellow costal band, covering 
more than half the breadth of wing, and extending almost from 
base to apex ; the ground colour sends a conical projection into 
this band before middle, cutting half through it, and midway 
between this and base is a much shorter, obtuse projection, both 
suffused with deep cobalt-blue ; the lower % of the reddish- 
ochreous inner-marginal portion is marked from base to apex 
with regular transverse strigule of brilliant deep cobalt-blue, 
appearing black in some lights; cilia reddish-ochreous round 
apex, thence dark fuscous-grey. Hind wings and cilia dark 
fuscous-grey. Male and female, length 6 lines. 
This magnificent species is unsurpassed in the elegance and 
intensity of its colouring. I took one pair in dense swampy 
forest in January, near Hamilton, on the Waikato. It seems to 
be nearly allied to the North American G. violacella, Clem., and 
G. blandella, Clem:
