lines; the discal spot is edged with brown in D. auriscriptella also, and is 
not curved at all in that species, though the posterior edge is concave, and 
the anterior as well; the series of longitudinal metallic lines is also present 
in D. auriscriptella ; and I believe the size given is too large. However, the 
white hindwings and the almost wholly leaden-metallie discal spot consti- 
tute in themselves a sufficient distinction. 
The specimen is stated to be from Dr. Hector’s collection ; which I 
understand to have been mainly taken by Mr. J. D. Enys in the neighbour- 
hood of Mount Hutt. 
7. Dipt. auriscriptella, Walk. 
(Eromene auriscriptella, Walk., Brit. Mus. Cat., 976.) 
Male, female—14-15 mm. Head and thorax light yellowish-ochreous. 
Palpi rather long, ochreous-orange, base and apical third dark fuscous. 
Antenne whitish-ochreous. Abdomen paleochreous-grey. Legs ochreous- 
grey-whitish. Forewings triangular, very broad posteriorly, costa gently 
arched, apex rounded, hindmargin oblique, second sinuation slight; pale 
yellowish-ochreous, deeper ochreous on disc, and towards apex and hind 
margin; costa dark fuscous towards base; a slender double dark fuscous 
transverse line from costa at } to middle of inner margin, strongly and 
regularly curved outwards, inner line obsolete on upper half, diverging 
somewhat on inner margin, enclosing on lower two-thirds a leaden-metallic 
line, becoming shining whitish on inner margin; a very small dark fuscous 
spot on middle of costa; a small elongate transverse spot in disc beyond 
middle, narrowed in middle, upper half leaden-metallic, lower half white; a 
slender double dark fuscous transverse line from costa at $ to inner margin 
a little before anal angle, rather obsolete on disc, upper two-thirds strongly 
outward-curved, lower third sinuate, included space indistinctly shining 
whitish ; two longitudinal leaden-metallic streaks between discal spot and 
hindmargin, nearly reaching both, a much shorter streak below them, and 
rest of second transverse line spotted with leaden-metallic on intersection of 
veins ; a leaden-metallic dot in apex; three small subquadrate black spots 
near together on hindmargin below middle: cilia rather dark grey, with a 
deep grey brassy-metallic basal line. Hindwings grey, with a dark grey 
hind-marginal line ; cilia grey. 
Distinguishable from all but D. chrysochyta by the discal spot, which has 
the upper half leaden-metallic and the lower white; it is a duller and paler 
insect than D. chrysochyta, without indentation on the first transverse line. 
Crambus gracilis, Feld., is not a synonym of this species, as stated by Butler, 
but of D. lepidella. 
Several specimens taken at Wellington and Port Lyttelton in January
