of 13 triangular spines, that commence just beyond the notch 

 and extend to the postero-distal angle; these spines are 

 strongly denticulated on the edge that faces posteriorly, 

 and the denticulations become more numerous, and also the 

 spines longer and more acuminate, toward the posterior 

 angle. Parallel with this row is a row of simple setae that 

 extend for a short distance beyond the angle along the 

 posterior border. In the Mt. Kosciusko specimens the palm 

 is strongly convex, and, in addition to the row of simple 

 setse, instead of 13 denticulated teeth there are only 9 and 

 these are of similar form, but not toothed. This character was 

 constant in each of the specimens examined. Secondly, the 

 terminal segment has the inferior margin fringed with 9 spinules 

 (not 15 or 16 as mentioned by Chilton), which gradually increase 

 in length hindwards, and all are more or less pectinated at the 

 tips, with the exception of the last one, which is simple ; also, in 

 addition to these, there is distally a sub-marginal cluster of three 

 little pectinated spinules. The uropoda are similar to Chilton's 

 drawing, with the addition of having a very conspicuous long 

 spine at about half-way along the upper margin of each ramus. 

 In other respects of form they essentially agree. 



DESCRIPTION OF A NEW AUSTRALIAN BUTTERFLY 



XENIGA TASMANIGA. 



By Geo. Lyell, Jnr. 



[Read before the Field Naturalists' Club of Victoria, \0th Sept., 1900.) 



Expanse, — Male, 35 mm. ; female, 37-38 mm. Face brownish- 

 black ; crown ferruginous. Palpi dark-ferruginous above, fuscous 

 below. Antennae ferruginous, club brownish-black, tipped 

 with ferruginous. Thorax and abdomen brownish-black ; legs 

 reddish-ferruginous. 



Wings. — Upperside rich brownish-black, with interrupted 

 transverse bands of whitish-ochreous ; basal fourth clothed with 

 long hairs, greenish-black on primaries and fuscous on secondaries; 

 cell at base and between bands black. Primaries. — First band 

 from upper median vein at 5^ and not reaching vein 1 at ]4, 

 dilated outwardly below cell, that portion within cell much 

 broader in male than in female. Second band from upper median 

 vein at f to lower median at starting point of vein 3. Third band 

 from costa atf to vein 1 at f of dorsum (hind margin), but inter- 

 rupted at veins 4 and 2, and dilated outwardly between veins 2 and 

 3. Between third and fourth bands a transverse row of three 

 white-centred black spots. Fourth band narrow, diminishing, 

 interrupted at veins, from below costa at T \ to just before vein 3.
