460 DESCKIPTIOlfS OF ATJSTRALIAJf MICEO-LEPIDOPTEEA, 



Palpi moderate, second joint hardly reaching base of antennse, 

 much dilated with dense scales, beneath with loose somewhat 

 projecting scales beyond middle ; terminal joint almost as long 

 as second, rather stout, somewhat roughened anteriorly, strongly 

 recurved. Thorax smooth. Eorewings elongate, rather broad, 

 apex somewhat rectangular, acute, hmdmargin slightly oblique, 

 almost straight or slightly concave beneath apex. Hiudwings 

 slightly narrower than f orewings, oblong- ovate, hindmargin faintly 

 sinuate, cilia | to i. Abdomen stout, strongly margined. Posterior 

 tibi« clothed with long fine hairs. Eorewings with vein 7 to 

 hindmargin, 2 from somewhat before angle of cell. Hindwings 

 normal. 



A small well-marked genus, nearly allied to Ileliocausta, of 

 which is is probably a development, and also with marked affinity 

 (perhaps collateral) with Eochroa ; it is well distinguished 

 amongst the group with unpectinated basal joint of antennae and 

 vein 7 terminating in the hindmargin, by the structure of the 

 palpi. The species are handsome and strikingly marked insects ; 

 the six known to me may be thus distinguished : 



A. Thorax wholly black anteriorly. 



1. Posterior fascia straight, dark fuscous... 29. clerota. 



2. Posteriorfasciairregular, ochreous-brown 31. decisana. 



3. Posterior fascia suffused, grey... ...HO. r/Iauco?ie])Jiela. 



B. Shoulders only black. 



. 1. Forewings pinkish-grey, without fasciae. 

 a. Porewings with a blackish costal spot 



before middle ... ... ...SH. quadripicsfuleUa. 



h. Porewings without blackish costal spot 



before middle ... H2. melanoma. 



2. Porewings white, fasciated ... ...28. divisella. 



28. Zon. divisella, Walk. 

 (Oecophora divisella, Walk., Brit. Mus. Cat. 677, (non 685).
