This is a good genus, allied to Eupselia, though very dif- 

 ferent in appearance, and characterised by the peculiar palpi. 

 Mr. Lower has kindly sent me examples of his xi pho^pma and 

 hiwacula; the following species is nearly related, especially to 

 the latter species, but distinct. 



Heterohatkra tetracentra, n. sp. 



Male, 18 mm. Head pale fuscous. Palpi dark fuscous, 

 white towards base beneath. Antennae fuscous. Thorax 

 whitish-fuscous, irrorated with dark fuscous. Abdomen 

 whitish-grey-ochreous, sprinkled with fuscous. Forewings 

 elongate, costa strongly arched, apex obtuse, termen obliquely 

 rounded ; whitish-fuscous densely irrorated with dark fuscous ; 

 rather large roundish spots of dark fuscous suffusion in disc 

 at |- and § ; a patch beneath middle of disc between these ap- 

 pearing pale throufifh obsolescence of dark fuscous irroration : 

 cilia whitish-fuscous, with irregular subbasal fuscous line. 

 Hindwings fuscous ; cilia as in forewings. 



Geraldton, West Australia, in November ; one specimen. 



Heterochyta, n. g. 



Head with appressed hairs, sidetufts projecting between 

 antennae; tongue developed. Antennae |, in male minutely 

 ciliated (J), basal joint moderately elongate, without pecten. 

 Labial palpi very long, straight, porrected, second joint 

 clothed with dense rough projecting hairscales above and be- 

 neath, terminal joint J-| of second, moderate, acute or toler- 

 ably pointed. Forewings with 2 from J-f , 3 from angle, 7 

 and 8 stalked, 7 to apex. Hindwings 1, elongate-ovate, cilia 

 h ', 3 and 4 connate, 5, 6, 7 parallel. 



Type Id. xenomor'pha. Nearly allied to the preceding 

 genus, but tne palpi are peculiar and cliaracterisUc, approach- 

 ing those of Phurota. The three species are readily sepa- 

 rated by the colour of the stigmata and proportions of the 

 palpi : — 



Stigmata blackish xenomorpha. 



Stigmata pale reddisli-ochreous pyrosema. 



Stigmata white asteropa. 



Heterochyta xenomorpha, n. sp. 

 Male, 19 mm. Head and thorax fuscous-whitish, shoul- 

 ders greyer. Palpi 6, dark fuscous finely sprinkled with whit- 

 ish, white beneath, terminal joint I, acute. Antennae white 

 ringed with fuscous. Abdomen pale fuscous mixed with whit- 

 ish. Forewings elongate, moderate, costa strongly arched, 

 apex obtuse, termen nearly straight, rather strongly oblique ; 

 2 from f ; fuscous very finely sprinkled with whitish points, 

 with a very few scattered black specks ; stigmata small, blackish.
