in male. Hindwings broader than forewings. Forewings with 12 veins, 7 
and 8 separate, 7 to hindmargin. Hindwings with 8 veins, 8 and 4 from a 
point, 5 approximated to 4 at base, 6 and 7 separate or stalked. 
This genus belongs to a group very extensively represented in the 
northern hemisphere, but practically absent from Australia. The single 
New Zealand species stands quite alone ; I at first erroneously referred it to 
Cacoecia, which it closely resembles in most respects, but the basal pectina- 
tion, which I had overlooked, is strongly marked, and I have now no doubt 
of its true position. See Vet XYL F I4 6

Male, female.—16-22 mm. Head and thorax pale ochreous or almost 
whitish, often suffused with fuscous ; palpi elongate. Forewings moderately 
broad, in male posteriorly dilated, costa moderately arched, hindmargin 
sinuate, not oblique; pale greyish-ochreous or sometimes whitish, generally 
strigulated, and more or less irregularly suffused with fuscous or dark 
fuscous, sometimes wholly fuscous; costa shortly strigulated with dark 
fuscous; markings fuscous or dark fuscous, darkest in the paler specimens, 
nearly obsolete in the darker; outer edge of basal patch indicated by a 
darker line, sharply angulated above middle, lower $ in male thick, generally 
conspicuously blackish-fuscous ; central fascia from before middle of costa 
to before anal angle, costal third generally conspicuously darker fuscous or 
blackish-fuscous, moderate in male, very narrow in female, lower two-thirds 
strongly dilated, not darker than ground-colour except on edges, anterior 
edge more distinct, very irregular, posterior edge angulated near inner 
margin; a very ill-defined triangular costal spot about 3, and a small spot 
towards middle of hindmargin, often connected by an oblique strigula ; the 
large triangular space between basal patch and central fascia in male often 
conspicuously paler than rest of wing: cilia whitish-ochreous, with a fuscous- 
grey basal line. Hindwings grey-whitish or light grey, spotted with grey ; 
cilia whitish, with two grey lines. 
An exceedingly variable species, but always dull-coloured ; some varielies 
of the female in colour and form approach the female of Cacoecia excessana, 
and are only separated with ease by the family characters.
