followed by a paler yellow line, from f of costa to ■§ of inner margin, upper 

 half strongly curved outwards, lower half nearly straight ; three obscure 

 light metallic-grey longitudinal streaks on upper half of wing, extending 

 from before second line to hindmargin ; three small quadrate black spots on 

 hindmargin below middle : cilia shining grey, with a darker metallic basal 

 line. Hindwings and cilia grey. 



A conspicuous species, easily recognized by the uniform deep yellow 

 forewings and double black dot representing the discal spot, with grey hind- 

 wings ; it may be placed after D. auriscriptella, Walk. 



Near the foot of the Otira Gorge, frequenting rock-faces where moss 

 grows, in January; I found it very common, but in a very restricted locality. 

 17. Dipt, bipunctella, Walk. 

 (Eromene bipunctella, Walk., Suppl., 1761.) 



I saw this insect in the British Museum, and identified it as certainly a 

 new species of Diptychophora ; from the type I made a brief diagnosis. 



Size of D. auriscriptella. Forewings brown, very neatly marked, mark- 

 ings much as in D. auriscriptella, discal spot small, round, white : cilia 

 white except near apex. Hindwings grey. 



Immediately distinguished by the uniform brown forewings, small round 

 white discal spot, and grey hindwings ; intermediate between D. holanthes 

 and D. epiplxaa. 



Locality given as New Zealand, without further indication.

Male, female. — 12-14 mm. Head, palpi, antennae, thorax, abdomen, 

 and legs fuscous. Forewings broad, triangular, costa hardly arched, apex 

 rounded, hindmargin oblique, slightly rounded, once indented below apex ; 

 fuscous, with green reflections ; lines slender, irregularly denticulate, dark 

 fuscous ; first line from beyond ^ of costa to before middle of inner margin, 

 angulated above middle and bent inwards below middle ; discal spot obsolete 

 or represented by a faint darker suffusion ; second line from f of costa to f 

 of inner margin, angulated above middle, thence tolerably straight ; some- 

 times two or three whitish longitudinal streaks towards hindmargin above 

 middle ; a small black apical spot : cilia whitish, with a shining dark grey 

 basal and lighter median line. Hindwings grey or dark grey, with greenish 

 reflections ; cilia light grey, with a dark grey basal line. 



Allied to D. bipunctella, from which it is distinguished by the much less 

 distinct markings, and the absence of the white discal spot. 



Arthur's Pass, about 3,000 feet, in January ; six specimens. 

 19. Dipt, elaina, Meyr. 



In this species the discal spot should have been described as terminating 

 beneath in a round white dot ; this is sometimes obscure, and was therefore 

 overlooked previously, but is always present.
