very small triangular yellow spot on inner margin at J ; an equally small 

 rather subquadrate yellow spot on inner margin at f , with a pale yellow dot 

 rather above and beyond its apex ; a very faintly perceptible darker trans- 

 verse line from costa at J 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 f , 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. — 11|— 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. Antenna 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- 

 tinctly 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 f to inner margin at f , 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
