 from Eucalyptus. Most allied to H. acmaea and probably also 

 H. lihylacopis, bvit not veiy near either. 



EucHAETis, Meyr. 



To the characters of this genus should be added : Hind wings 

 with veins 3 and 4 separate at origin. This character readily 

 separates it from Heliocmista, to which the discovery of the 

 additional species recorded below shows that it is otherwise very 

 nearly allied. The antennal cilia tions of the ^ vary specifically 

 from 3 to 5.

(J^. 31-33 mm. Head pale greyish-ochreous, face more 

 whitish. Palpi grey-whitish, mixed with rosy. Antennae whitish- 

 grey, ciliations 3. Thorax pale greyish-ochreous, with a ferruginous 

 irroration forming a diamond-shaped posterior spot, a narrow 

 central longitudinal streak, and a small spot in middle of each 

 patagium. Abdomen and legs pale whitish-ochreons, anterior legs 

 rosy, middle tarsi rosy except apex of joints. Forewings rather

 with very pale greyish-ochreous ; markings very pale greyish- 

 ochreous ; costal edge rosy ; a short streak along base of inner

 costal streak, rather broad at base, emitting two irregular oblique 

 wedge-shaped projections, at J and middle, first running to fold 

 before middle, second to a whitish dot in disc at I ; three ill- 

 defined grey-whitish dots beneath posterior half of costal streak, 

 almost confluent with it ; a grey whitish submarginal line, becom- 

 ing marginal on lower half of hindmargin, anterior edge waved : 

 cilia very pale whitish-grey, with a pale grey-reddish line beyond 

 middle, tips whitish between apex and anal angle. Hindwings
