Male, 12-15 mm ; female, 15-16 mm. — Head, palpi, and thorax iu male 

 whitish-ochreous, ochreous, fuscous, or grey, in female whitish-ochreous ; 

 palpi elongate. Antennae whitish-ochreous or greyish, in male sharply 

 annulated with dark fuscous. Abdomen whitish-ochreous or grey. Legs 

 varying from whitish to dark fuscous. Forewings in male triangular, 

 moderate, costa moderately arched, somewhat bent in middle, hindmargin 

 almost straight, rather oblique ; in female rather oblong, dilated posteriorly, 

 costa strongly arched towards base, sinuate beyond middle, apex somewhat 

 produced, hindmargin somewhat sinuate, rather oblique ; in male pale 

 whitish-ochreous, whitish-grey, ochreous, fuscous, or dark fuscous-grey, 

 more or less distinctly strigulated or reticulated with darker ; in female 

 whitish-ochreous, reticulated with darker ochreous ; one whitish-grey male 

 has posterior half of wing reddish-fuscous, and one grey male has whole 

 wing except basal patch suffused with blackish-grey ; outer edge of basal 

 patch, central fascia, and costal spot generally ochreous-fuscous or fuscous, 

 more or less distinctly darker than ground-colour, but' sometimes wholly 

 obsolete in male ; outer edge of basal patch in male from \ of costa to \ of 

 inner margin, sharply angulated above middle, in female irregular, from \ 

 of costa obliquely outwards, angulated above middle, thence irregularly 

 concave, ending in middle of inner margin ; central fascia rather narrow, 

 straight, from middle of costa to inner margin before anal angle, generally 

 obsolete beneath, posterior edge dilated outwards into an abrupt suffused 

 projection above middle ; costal spot in male roundish, sometimes produced 

 as a fascia to anal angle, in female flattened semi-oval, often confluent with 

 projection of central fascia ; costal space between central fascia and costal 

 spot often conspicuously paler than ground-colour : cilia in male whitish 

 or whitish-ochreous, basal half blackish-grey, sometimes almost wholly 

 blackish-grey, in female whitish-ochreous, towards base dark ochreous- 

 fuscous. Hindwings in male varying from grey-whitish to dark grey, when 

 light spotted with darker, cilia paler, with a darker basal line ; in female 

 white, apex very faintly ochreous-tinged, cilia white. 



The variability of this species is extraordinary, the sexes being also very 

 different, and the various forms can hardly be included in a single descrip- 

 tion. From the preceding species the female is immediately distinguishable 

 by the white hindwings and different form, the male by the conspicuous 

 dark basal half of the cilia of forewings, the usually perceptible basal patch 

 and costal spot, and the much smaller size. 



Larva moderate, cyhndrical, slightly tapering at both ends ; pale greyish- 

 green, spots concolorous ; head pale greyish-ochreous, lateral margins dark 

 fuscous, mouth spotted with dark fuscous ; second segment greenish-whitish, 

 with an ochreous-tinged dorsal plate ; anal segment greenish- whitish, with a
