484 Mr. E. Meyrick on some 



beneath silvery-metallic on lower half; glandular swelling of hind 

 wings rather dark fuscous. 



Port Moresby (Koivald) ; two specimens. A curious 

 and very elegant species. 



Xenocentris, n. g. 

 Face smooth. Palpi short, slender, porrected. Antennae in S' 

 bideutate, ciliated with very long fascicles. Abdomen in (^ with 

 extremely large expansible tufts of hairs on genitalia. Middle 

 tibiae and much elongated basal joint of tarsi in ^ clothed with 

 long dense rough hairs above, inner spur very long and thick and 

 clothed with dense rough hairs above ; posterior tibiae in ^ very 

 short, without spurs, tarsi bent, abbreviated. Fore wings with 

 vein 6 remote from 9, 10 out of 9 below 8, 11 anastomosing with 9. 

 Hind wings with veins 3 and 4 stalked, 6 and 7 stalked. 



Also a development of the first group of Acidalia, 

 specially characterised by the peculiar middle legs ; the 

 extreme development of the genital tufts is noteworthy, 

 but probably less reliable as a generic character.
