 Male, female. — 25-37 mm. Forewings moderate, hindmargin rounded, 

 crenulate ; pale whitish-ochreous ; very numerous fine slightly dentate 

 ochreous-fuscous stria3 parallel to a line from f of inner margin to apex, 

 but somewhat bent near costa, and tending to form darker dots on veins ; 

 one about \, a second before middle, and a third slightly beyond middle 

 generally more conspicuous and partially marked with blackish, except 

 towards costa, third often more irregular and with a variable projecting 

 median tooth ; a minute black discal dot on second, sometimes enlarged 

 into a small round spot ; a sinuate dark fuscous or blackish line from 

 middle of disc to apex, suffused beneath. Hindwings moderate, hind- 

 margin slightly rounded, crenulate ; colour, transverse striae, and discal 

 dot as in forewings. 



Very variable, but always easily recognizable. 



Wanganui, Wellington, Nelson, Christchurch, Dunedin, "amongst bush, 

 common from November to June ; thirty-four specimens. 



21. Scot, deltoidata, Walk. 



(Coremia deltoidata, Walk., 1321; Cidaria inclarata, Walk., 1411; Cidaria per ductata, 



Walk., 1412; Cidaria congressata, Walk., 1412; Cidaria conversata, Walk., 1413; 



Cidaria descriptata, Walk., 1414 ; Cidaria bisignata, Walk., 1415 ; Cidaria aggregata, 



Walk., 1415 ; Cidaria congregata, Walk., 1415 ; Cidaria plagifurcata, Walk., 1416; 



Coremia pastinaria, Gn., E.M.M., v., 64 ; Cidaria inopiata, Feld., cxxxii., 3 ; Cidaria 



monoliata, Feld., cxxxii., 8; Cidaria perversata, Feld., cxxxii., 14, 24.) 



Male, female. — 30-36 mm. Forewings moderate, hindmargin slightly 



rounded, straight, or somewhat concave, more or less crenulate ; ochreous- 



brown ; numerous dark grey or dark fuscous somewhat irregular shortly 



dentate stria? ; a narrow dark fuscous fascia before middle, and a rather 



broader one beyond middle, more or less approximated, sometimes both cut 



below middle by a broad biconcave bar of ground-colour ; included median 



band often grey ; a small black transverse discal spot ; often first fascia 



preceded and second fascia followed by a narrow whitish or white fascia ; a 



very obscure whitish subterminal line. Hindwings moderate, hindmargin 



rounded, crenulate ; light brownish-ochreous, greyer towards base and 



inner margin ; numerous obscure incomplete dark grey stria?. 



Extremely variable, yet not so as to justify so long a list of synonyms. 

 Wellington, Christchurch, Mount Hutt, Dunedin, Lake Wakatipu, and 

 probably throughout the islands, abundant from December to February ; 

 fifty-two specimens. Mr. E. W. Fereday informs me that this species is 

 now scarce near Christchurch, where it was formerly very abundant, having 

 been nearly exterminated by the increase of birds.
