Adaluma, n. gen. 



Forewing with vein 11 parallel with vein 12, vein 6 arising 

 with vein 7, veins 1 to 7 (in male) bordered discally with 

 black scales; costa strongly arched; termen well rounded. 

 Hindwing evenly rounded, apex of cell acute, vein 3 arising 

 some distance below apex of cell. Beneath white, with 

 terminal series of dots. Antennae short, less than half ex- 

 panse of wings. Eyes smooth, palpi long. Type, A. urumeliay. 

 from the Northern Territory. 



Allied to Can-dalides, Hubner, to which it is similar in 

 venation. The shape of the cell of hindwing differs from C 

 xanthospilos, Hubner, in being more acute at apex. The 

 antennae are extremely short; in this character it resembles, 

 the peculiar genus Kesoli/caena^ from which otherwise it is 

 distinct . 



Tlie names chosen, ''adaluma" and "urumelia," are two 

 native (Nungubuyu tribe) words meaning "flowing stream" 

 and "butterfly." The butterfly was first taken on the banks 

 of the Roper River by a native, at the aborigines' reserve,, 

 which is over 70 miles from the sea.
