Very distinct through the peculiar three-toothed discal spot and the 

 white hlotch towards base ; allied to D. lepidella and D. leucoxantha, and in 

 respect of the hindwings intermediate. 



Three specimens taken by Mr. E. W. Fereday at Christchurch, Nelson, 

 and Akaroa respectively, in January. 



4. Dipt, lepidella, Walk. 



(Eromene lepidella, Walk., Brit. Mus. Cat. Suppl. ; Crambus gracilis, Feld., Eeise der 



Novara, PI. CXXXVIL, 26.) 



Male, female. — 19^-2(H mm. Head, antennae and thorax pale ochreous. 

 Palpi dark fuscous, at base white beneath. Abdomen whitish-grey-ochreous. 

 Legs whitish-ochreous. Forewings triangular, broad, costa slightly arched, 

 apex rounded, hindmargiu oblique, sinuations moderate ; pale yellowish- 

 ochreous ; costa somewhat suffused with brownish towards base ; a very 

 slender sometimes indistinct dark fuscous transverse line from costa at ^ 

 to inner margin before middle, costal third straight, outwardly oblique, 

 thence irregular, rather strongly bent inwards a little above inner margin ; 

 a small longitudinally-placed semicircular silvery-white spot in disc 

 beyond middle, its anterior angle shortly and narrowly produced up- 

 wards ; a short linear dark fuscous mark along middle of costa ; a 

 very slender sometimes indistinct dark fuscous transverse line from 

 costa at f to inner margin at f, suddenly bent outwards beneath 

 costa, thence moderately outwards-curved, lower third sinuate ; some- 

 times a triangular brown patch on costa immediately beyond first 

 transverse line, extending suffusedly to beneath discal spot ; a small suf- 

 fused brown spot on costa a little beyond second transverse line, sometimes 

 giving rise to a brown suffusion extending to beneath discal'spot where it 

 meets the first suffusion, but both these are sometimes wholly obsolete ; 

 three short linear longitudinal leaden-metallic streaks crossing second 

 transverse line above middle, and three very short similar streaks below 

 middle ; a dark fuscous hindmarginal line ; three small roundish black 

 spots close together on hindmargiu below middle : cilia shining grey, with 

 a dark metallic-grey basal line.. Hindwings fuscous-grey, with an indis- 

 tinct darker posterior line, and a dark fuscous hindmarginal line ; cilia 

 grey with a faint darker line. 



Most allied to D. leucoxantha, which it resembles in the character of the 

 discal spot, but is immediately known by the duller ground-colour and grey 

 hindwings ; in superficial colouring it is very similar to D. auriscriptella, 

 but is considerably larger, and the discal spot is wholly different. The 

 brownish suffusion in this species is very variable, as in D. cJiryso- 

 chyta.
