Heterocera from the Australian Region. 385 



apex rounded, outer margin slightly convex, very oblique, con- 

 tinuous with the inner margin, which is also slightly convex ; the 

 neuration of all the wings utterly unlike that of any of the white - 

 coloured genera of Liparidce ; costal vein of primaries terminating 

 at about the third fourth of costa; subcostal five-branched, the 

 first branch emitted before the end of the cell, and the four others 

 form a long footstalk ; of these four short branches the first and 

 fourth start almost from the same point, but from opposite sides of 

 the vein, the first running to costa, the last to outer margin, and 

 the intermediate pair form a short fork to apex; upper radial 

 emitted from the anterior angle of the cell, lower radial from the 

 posterior angle, where it appears as a fourth median branch ; disco- 

 cellular veinlet inangled ; median branches nearly equidistant ; 

 secondaries short, subpyriform ; costal vein running to apex ; dis- 

 coidal cell short, not reaching the middle of the wing ; subcostal 

 vein forked from a long footstalk at one-third the distance between 

 the cell and outer margin ; disco-cellular extremely slender, in- 

 angled ; no radial vein ; second and third median branches emitted 

 from a short footstalk ; head and thorax clothed with woolly hair ; 

 palpi depressed ; antennae short, pectinated ; abdomen with a large 

 anal tuft ; legs tolerably robust, clothed somewhat sparsely with 

 long silky hairs. 



In the branching of the subcostal nervure of the 

 primaries, the forking of the subcostal and median 

 veins of secondaries, and the total absence of a radial 

 vein in these wings, this genus is most abnormal. 



5. Chionophasma paradoxa, n. s. 



$ . Wings sernitransparent snow-white, with a faint silky gloss ; 

 two very slender greyish lines on the fringe ; body white, sparsely 

 scaled ; abdomen with golden ochraceous anal tuft ; under surface 

 coloured as above. Expanse of wings, 32 mm. 



Eockhampton. 



This species was sent as the female of the succeeding 

 Porthesia, to which, in common with many other 

 Liparidce, it bears considerable resemblance ; an exami- 

 nation of the structure would, however, convince the 

 most sceptical that there is no relationship between 

 them.
