528 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, 



Not very near any of the other species ; characterised by the 

 whitish groundcolour, grey markings, and especially the angulated 

 central fascia. 



I took five specimens amongst bush near Auckland and 

 Wellington, New Zealand, in January. 



21. AROTROPHORA, n. g. 



Thorax smooth. Antennae in male somewhat thickened, 

 strongly dentate, ciliated with tufts of hairs. Palpi very long, 

 second joint elongate-triangularly scaled, attenuated to apex, 

 terminal joint short, distinct. Fore wings elongate, costa in male 

 simple, gently and evenly arched, hindmargin obliquely rounded 

 or nearly straight. Hindwings rather elongate, broader than 

 forewings. Forewings with veins 7 and 8 separate, 7 running 

 to hindmargin. Hindwings with veins 3 and 4 rising from a 

 point, 5 approximated to 4 at base, 6 and 7 separate. 



Larva sixteen-legged, stout, feeding in seed-heads. 



Allied to Tortrix, but distinguished by the long palpi, and by 

 the antenna) of male, which are very strongly dentate, and 

 furnished with a tuft of cilia on the apex of each tooth.

A. Head and thorax ochreous-yellow ..2. xythopterana. 



B. Head and thorax dark fuscous . . . . 1. incessana. 

 0. Head and thorax whitish, sometimes 



greyish-tinged. 



1. Forewings without ochreous tinge ..5. confusana. 



2. Forewings with more or less reddish- 



ochreous suffusion.
