60 Transactions. — Zoology. 



in male. Hindwings broader than forewings. Forewings with 12 veins, 7 

 and 8 separate, 7 to hiiidrnargiu. Hindwings with 8 veins, 3 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.

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 f , 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-ocbreous, 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 varieties 

 of the female in colour and form approach the female of Cacoecia excessana, 

 and are only separated with ease by the family characters.
