The genus is tlie only one in the family, in which the fore- 

 wings have only 1 1 veins. Its nearest ally is the succeeding 

 genus Aeolocosma, from which it differs in the antennae of ^ 

 being quite simple, and in the neuration. The round black 

 metallic-edged hind-marginal spots are a remarkable secondary 

 characteristic, (shared also to some extent by Aeolocosma and 

 HypertrojyhaJ which is very constant and trustworthy. In repose 

 the images rest with the wings forming a rather sloping roof ; 

 E. aristonica extends the furry anterior legs in front, but this 

 habit is not shared by the rest. The species are all more or less 

 retired and sluggish in habit, and hence appear not common. 



The genus is peculiar to Australia, so far as known. Probably 

 it contains a considerable number of species ; the seven here 

 described may be thus tabulated : — 



I. Hind-wings yellow at base. 



A. Fore-wings with a dark fuscous blotch on 



inner-margin . . . . . . . .4. beatella 



B. Fore-wings without dark fuscous blotch 



on inner-margin. 



1. with three black hind-marginal spots 3. carpocapsella 



2. with five black hind-marginal spots . .6. theorella 



II. Hind- wings wholly fuscous-grey or blackish. 



A. Fore-wings brownish-ochreous, irrorated 



with whitish . . . . . . . .7. melanostrepta 



B. Fore- wings with basal half yellow, apical 



purple .. .. .. .. . .5. satrapella 



C. Fore-wings blackish. 



1 . with white spots near base of inner- 



margin and on costa . . . . 1 . aristonica 



2. without white spots . . . . . .2. percussana
