towards base, especially round apex. Hindwings whitish, faintly yellowish- 
tinged posteriorly, and spotted with grey; cilia whitish, with a grey basal 
line. 
Remote from all its congeners in superficial appearance ; the peeuliar 
angulated subcostal mark at base, (differing in the sexes), is unique in its 
way, but only conspicuous in the male. 
Common at Christchurch, Wellington, and Dunedin, generally in 
gardens, in January, February, March, and August. 
7. Cacoxrcra, Hb. 
Thorax smooth. Antenne in male ciliated. Palpi moderate or rather 
long, porrected, second joint triangularly scaled. Forewings in male with 
strong costal fold. 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 at base to 4, 6 and 7 separate (rarely 
stalked). 
Distinguished from Harmologa by the origin of veins 8 and 4 of the 
hindwings from the same point, from Tortrix by the costal fold of male. 
Of the species which I originally referred here, four have been satisfactorily 
determined to be mere varieties, three have been transferred to the neigh- 
bouring Harmologa, one (of which the male had been unknown) to Tortriz, 
and one is removed to the Grapholithide, the basal pectination of the hind- 
wings having been overlooked. I have now only two true species of 
Cacoecia from New Zealand; the genus 1s numerously represented in 
Australia.

Var.a. Alis ant. macula disci ante medium parva albida. 
Male, female.—19—298 mm. Head and thorax varying from ochreous to 
dark fuscous or purple-fuscous (sometimes discolorous); palpi rather long. 
Forewings moderately broad, posteriorly dilated, less in female, costa 
moderately arched, in female straighter posteriorly, hindmargin sinuate, 
not oblique ; varying from ochreous to dark ochreous-fuscous, finely strigu- 
lated with darker, sometimes wholly suffused with purple; markings very 
ill-defined, hardly darker than ground-colour, often wholly obsolete; outer
