very small triangular yellow spot on inner margin at 1; an equally small 
rather subquadrate yellow spot on inner margin at 3, with a pale yellow dot 
rather above and beyond its apex ; a very faintly perceptible darker trans- 
verse line from costa at 4 to first dorsal spot, sharply angulated outwards 
beneath costa ; a suffused darker spot in disc above and beyond middle; a 
small outwardly oblique triangular pale yellow spot on costa at $, some- 
times closely preceded by a faint oblique yellowish costal mark; a very 
small suffused pale yellowish spot on costa before apex ; a dark fuscous dot 
in apex, preceded by a clear white dot; sometimes a white dot on hind- 
margin in upper indentation; a slender dark fuscous hindmarginal line: 
cilia whitish ochreous, with a dark grey line near base, on indentations 
wholly clear white, a dark grey spot at apex, another between indentations, 
a third above anal angle, a fourth on anal angle. Hindwings fuscous-grey, 
with a very indistinct darker line posteriorly ; a dark fuscous hindmarginal 
line; cilia grey-whitish, with a grey line near base. 
Very distinct through the dark purplish-fuscous suffusion of the fore- 
wings, causing the discal spot to be obsolete, and throwing the yellow 
marginal spots into sharp relief; the spotted cilia also afford a good 
character. 
Common at Wellington in January amongst scrub, and also at Lake 
Wakatipu ; probably widely distributed. 
2. Dipt. chrysochyta, n. sp. 
Male.—114-12 mm. Head and thorax pale ochreous. Palpi ochreous- 
yellow, with a dark fuscous spot at base and apical half dark fuscous, in- 
ternally whitish-ochreous. Antenne whitish-ochreous. Abdomen whitish- 
ochreous-grey. Legs pale whitish-ochreous. Forewings triangular, very 
broad posteriorily, costa very gently arched, apex rounded, hindmargin 
oblique, sinuations moderately deep; light yellowish-ochreous, apex and 
hindmargin narrowly suffused with brownish, in one specimen basal half 
wholly suffused irregularly with brownish; a well-defined double dark 
fuscous transverse line from costa near base to inner margin before middle, 
very strongly curved outwards, dentate inwardly a little above inner margin, 
enclosing a pale line becoming almost clear white on inner margin ; an 
oblique dark fuscous mark on costa beyond middle, giving rise to an indis- 
tinetly dentate suffused brown transverse line to middle of inner margin, 
which it hardly reaches; this line bounds the brown suffusion in the darker 
specimen ; on it, rather above middle, is a small transverse 8-shaped spot, 
upper half leaden-metallic, lower half clear white ; a slender rather irregular 
dark fuscous transverse line from costa at $ to inner margin at , upper 
two-thirds very strongly curved outwards, lower half nearly followed by a 
similar line, diverging a little on inner margin; this line is preceded and
