followed by a paler yellow line, from $ of costa to $ of inner margin, upper 
half strongly curved outwards, lower half nearly straight; three obscure 
light metallic-grey longitudinal streaks on upper half of wing, extending 
from before second line to hindmargin ; three small quadrate black spots on 
hindmargin below middle: cilia shining grey, with a darker metallic basal 
line. Hindwings and cilia grey. 
A conspicuous species, easily recognized by the uniform deep yellow 
forewings and double black dot representing the discal spot, with grey hind- 
wings; it may be placed after D. auriscriptella, Walk. 
Near the foot of the Otira Gorge, frequenting rock-faces where moss 
grows, in January; I found it very common, but in a very restricted locality. 
17. Dipt. bipunctella, Walk. 
(Eromene bipunctella, Walk., Suppl., 1761.) 
I saw this insect in the British Museum, and identified it as certainly à 
new species of Diptychophora ; from the type I made a brief diagnosis, 
Size of D. auriseriptella. Forewings brown, very neatly marked, mark- 
ings much as in D. auriscriptella, diseal spot small, round, white: cilia 
white except near apex. Hindwings grey. 
Immediately distinguished by the uniform brown forewings, small round. 
white discal spot, and grey hindwings; intermediate between D. holanthes 
and D. epiphea. 
Locality given as New Zealand, without further indication. 
18. Dipt. epiphea, n. sp. 
Male, female.—19-14 mm. Head, palpi, antenne, thorax, abdomen, 
and legs fuseous. Forewings broad, triangular, costa hardly arched, apex 
rounded, hindmargin oblique, slightly rounded, once indented below apex ; 
fuscous, with green reflections; lines slender, irregularly denticulate, dark 
fuscous ; first line from beyond } of costa to before middle of inner margin, 
angulated above middle and bent inwards below middle; discal spot obsolete 
or represented by a faint darker suffusion ; second line from 3 of costa to $ 
of inner margin, angulated above middle, thence tolerably straight; some- 
times two or three whitish longitudinal streaks towards hindmargin above 
middle; a small black apical spot: cilia whitish, with a shining dark grey 
basal and lighter median line. Hindwings grey or dark grey, with greenish 
reflections ; cilia light grey, with a dark grey basal line. 
Allied to D. bipunctella, from which it is distinguished by the much less 
distinct markings, and the absence of the white discal spot. 
Arthur’s Pass, about 8,000 feet, in January; six specimens. 
19. Dipt. elaina, Meyr. 
In this species the discal spot should have been described as terminating 
beneath in a round white dot; this is sometimes obscure, and was therefore 
overlooked previously, but is always present,
