29. Cid. rixata, Feld. 
(Cidaria rirata, Feld., cxxxii., 1; Coremia squalida, Butl., Cist. Ent., ii., 505.) 
Male, female.—24-82 mm. Forewings moderate, hindmargin sinuate, 
crenulate; rather dark ashy-grey, somewhat mixed partially with light 
olive-green ; numerous irregular dentate dark fuscous strie, except on a 
median space, containing a black discal dot; basal third somewhat mixed 
with whitish, with two cloudy angulated whitish strie at }, partially suf- 
fused with greenish, and two others less angulated rather nearer base ; 
beyond the posterior pair the dark stria coalesce on lower half to form a 
blackish fascia ; a double whitish line considerably beyond middle, dentate 
anteriorly, sinuate near costa, obtusely bent outwards in middle, emitting 
a long sharp tooth inwards below middle; beyond these a third parallel 
less distinct whitish or greenish line; a very sharply dentate whitish sub- 
terminal line, closely approaching this on lower half, anteriorly suffusedly 
blackish-margined ; an oblique suffused blackish subapical spot. Hind- 
wings moderate, hindmargin rounded, crenulate ; in male whitish-ochre- 
ous, becoming greyish towards base, in female light grey; a grey discal 
dot; an obscure angulated median band somewhat darker, or represented 
by several incomplete strie; an obscure grey dentate subterminal line. 
Constant; immediately recognizable from all other species of the 
family in New Zealand by the very fine acute indentation of the posterior 
margin of the median band below middle.

bush in January; twenty-four specimens. 
30. Cid. purpurifera, Fereday.

sinuate, crenulate; dull rather light olive-green; two obscure irregular 
dentate blackish strie near base, second followed by whitish scales; two 
irregular sinuate dentate blackish strie at 4, curved outwards above middle, 
suffusedly confluent on lower half, first slightly whitish-margined anteriorly ; 
two other very irregular dentate blackish strie beyond middle, forming a 
. broad subquadrate projection in middle third, which is wholly suffused with 
dark fuscous, second posteriorly white-margined, more broadly towards 
costa; between these two pairs of strie the included median band is dull 
greyish-purple; a dentate white subterminal line; an oblique blackish sub- 
. apical spot, white-margined above. Hindwings moderate, hindmargin 
rounded, crenulate ; light brownish-ochreous.
