spot on costa at |-, giving rise to a curved cloudy blackish-grey transverse 

 line to anal angle ; all these grey markings are sometimes partially suffused 

 and confluent ; a cloudy dark grey apical spot : cilia white, irregularly 

 mixed with dark grey, forming a cloudy spot at apex and anal angle. Hind- 

 wings pale grey ; cilia grey-whitish. 



Separable from GE. epimylia by the larger size, ochreous-white head, and 

 white ground-colour of forewings ; from GE. hemimochla by the distinct grey 

 costal spots and transverse fascias, and always well-defined oblique streak 

 beneath fold. 



Christchurch, Dunedin, Lake Wakatipu, and Invercargill, in December 

 and January ; rather common.

Minor, alis ant. albidis, griseo-conspersis, striga sub plica posita obliqua, 

 punctis disci duobus, striga anguli analis obliqua, rnaculaque suba/picali 

 nigricantibus ; post, albido-griseis ; capite ochreo-albo. 



Male, female. — 14^—16 mm. Head ochreous-whitish. Palpi ochreous- 

 whitish, basal f of second joint, and base and apex of terminal joint 

 suffused with dark fuscous. Antennas grey. Thorax ochreous-whitish, 

 more or less mixed with grey. Abdomen ochreous-whitish. Anterior and 

 middle legs dark fuscous, central ring of middle tibiae, and apex of all joints 

 ochreous-whitish ; posterior legs ochreous-whitish. Forewings moderate, 

 costa moderately arched, apex rounded, hindmargin very obliquely rounded'; 

 white, irregularly suffused with whitish-ochreous, and sprinkled with grey 

 and a few blackish scales ; costal edge dark fuscous at base ; an oblique 

 dark fuscous streak from fold before middle to near inner margin before \, 

 generally distinct on fold only ; a blackish dot in disc before middle, and a 

 larger one beyond middle, sometimes connected with apex of oblique streak 

 by a cloudy dark fuscous line ; a cloudy dark fuscous bar extending from 

 anal angle almost or quite to second discal dot ; a cloudy dark fuscous 

 apical spot, suffusedly produced along hindmargin ; sometimes a curved 

 transverse cloudy dark fuscous line near hindmargin, indented inwards 

 beneath costa, often obsolete : cilia whitish, with rows of dark fuscous 

 points, forming a cloudy spot at apex and anal angle. Hindwings whitish- 

 grey or light grey ; cilia grey- whitish. 



Closely aUied to CE. contextella, and best separated by the absence of the 

 distinct lighter and darker spots of the costa ; also somewhat larger and 

 duller, less variegated, without entire fasciae, the oblique streak beneath the 

 fold not generally distinct, and the hindwings lighter. 



Hamilton, Wellington, and Napier, in January and March ; rather 

 common. Probably this species may be confined to the North Island, and 

 CE. contextella to the South.
