436 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, 



blotch is a short black longitudinal streak in middle of disc ; 

 beyond the oblique line are two or three obscure dark fuscous 

 transverse lines from costa, uniting with it : cilia greyish-fuscous, 

 barred with dark grey, and with a slender black waved basal 

 line. Hindwings fuscous-grey, cilia rather darker, with a dark 

 basal line. 



<j> . 13". Forewings rather abruptly arched near base, dull 

 greyish-fuscous indistinctly clouded with darker ; markings as 

 in male but very suffused and indistinct, central blotch obscured, 

 black longitudinal streaks before and beyond middle slender but 

 clearly perceptible. Hindwings more ochreous-tinged than in 

 male. 



Recognisable in both sexes by its dark and suffused colouring. 

 Described from my own specimens, the identity of which with 

 Walker's species is not absolutely assured ; Walker's type is a 

 single female (one of the Geometrina has been subsequently added 

 as a second example), of which the f orewings appear to be some- 

 what roughened with raised scales, and more blackish-tinged ; 

 but in the absence of sufficient material I think it will be best to 

 consider the specimens as forming only a single species. 



I have two specimens (male and female) taken near Melbourne 

 by Mr. GK H. Eaynor. Walker's specimen is from Tasmania. 



Note. I have another female of this genus (also from Mel- 

 bourne), which may either be a variety of the above, or a new 

 species; it is smaller (11-a-") but similar in shape, the f orewings 

 more variegated with lighter fuscous and ochreous, the hind wings 

 pale ochreous spotted with grey, with dark grey hindrnargm.
