Peculiarly characterized by the strong sinuate black discal streak.
Three specimens taken near Dunedin.
24. Dipt. incessana, Walk.
(Teras incessana, Walk., Brit. Mus. Cat., 304, (Arotrophora) Meyr., Proc. Linn. Soc. N.S.W., 1881, 529.)
Minor, alis ant. fuscis, fascia media directa, macula costæ triangulari, alteraque anguli analis angusta erecta saturatioribus; post. griseis.
Male, female.—13–16 mm. Head and thorax dark fuscous; palpi rather long. Forewings moderately broad, subtriangular, costa moderately arched, hindmargin sinuate, oblique; dull reddish-fuscous, strigulated with darker, with dark reddish-fuscous markings; outer edge of basal patch indicated by an indistinct rather irregular line; central fascia moderately broad, not oblique, from middle of costa to middle of inner margin, anterior edge straight, well-defined, posterior edge suffused, connected with a cloudy spot in disc beyond middle; a triangular spot on costa at ¾; a short erect streak from anal angle, reaching nearly half across wing: cilia pale reddish-fuscous, with a strong blackish basal line. Hindwings grey, indistinctly spotted with darker; cilia pale grey, with a darker basal line.
Considerably broader-winged than the following species, and widely distinct by the fuscous colouring and straight perpendicular central fascia.
I took one specimen at Auckland in January; Mr. R. W. Fereday has two others, taken at Christchurch in November and December.
25. Dipt. imbriferana, Meyr.
(Dipterina imbriferana, Meyr., Proc. Linn. Soc. N.S.W., 1881, 527.)
Parva, alis ant. albidis, area basali, fascia media angulata, macula costæ, alteraque anguli analis griseis; post. griseis.
Male, female.—9½–12 mm. Head and thorax whitish; palpi moderate. Forewings rather narrow, not dilated, costa moderately arched, hindmargin obliquely rounded; whitish, sometimes faintly clouded with grey, obscurely strigulated with fuscous-grey; basal patch more or less fuscous-grey, outer edge irregularly angulated in middle; central fascia suffusedly fuscous-grey, obscurely margined with dark-fuscous, moderate, rather narrower towards costa, running from middle of costa to middle of inner margin, angulated in middle; apical portion of wing more distinctly strigulated with fuscous-grey, strigulæ generally coalescing to form a spot on costa at ¾, a smaller spot on anal angle, and sometimes one on middle of hindmargin: cilia whitish, with a grey basal line. Hindwings grey, darker posteriorly; cilia grey, with a darker basal line.
An inconspicuous species, yet not like any other.
Taken at Auckland and Wellington in January.
