Meyrick.—On New Zealand Micro-Lepidoptera. 23 
dark fuscous, basal joint pale green. Thorax pale green, a small spot on 
each side of neck, an oblique mark on each side of back, and a small poste- 
rior spot black. Abdomen whitish-grey. Legs dark fuscous, tibie with 
central and apical rings, tarsi with apex of joints whitish, posterior tibie 
with whitish hairs above. Forewings moderate, costa gently or moderately 
arched, faintly sinuate in middle, apex obtuse, hindmargin oblique, slightly 
sinuate or nearly straight; pale green, with sharply defined black linear 
markings; a dot at base, and a small mark near base on costa, connected 
along costal edge; a dot on inner margin near base; a mark very near 
base and an inwardly oblique bar in disc at 4, connected centrally by a lon- 
gitudinal line; an oblique bar from costa at +, forked at apex, not reaching 
middle; a short longitudinal mark beneath fold at +, anteriorly furcate ; a 
short oblique bar in disc below middle, very shortly furcate beneath; a 
short sinuate oblique bar in disc beyond middle, furcate above, (in Southern 
specimens connected centrally with preceding by a longitudinal line) ; all 
these markings preceded in dise by tufts of raised scales; a spot on costa 
beyond middle, furcate at apex; a sinuate dentate transverse bar in disc 
about 4; a row of small spots along hindmargin and apical third of costa: 
cilia pale green. Hindwings grey-whitish, posteriorly suffused with fuscous 
grey, with an obscure darker central spot, and a dark fuscous interrupted 
hindmarginal line ; cilia whitish-grey, becoming whitish-green round apex, 
with a faint darker line. 
A beautiful insect, mimicking the colour of the long drooping lichens 
on which it always sits, and on which the larva probably feeds; the mark- 
ings are not united to form complete transverse strige, as in S. picarella. 
Butler’s huttonii is merely a bleached specimen. 
Hamilton, Christchurch, Dunedin, in December and January ; tolerably 
common, and probably widely distributed. The slight difference in mark- 
ing between forms from the North and South Islands is worthy of notice.
