I have specimens in my collection which vary considerably in intensity 
of colouration, ranging from with light yellow fore wing and white hind wing to 
an olive-lake (xvi) fore wing and light greyish olive (xlvi) hind wing. The 
antennae of the £s are with rather long pectination. A considerable variation 
is found in the venation of the fore wing as shown in the following table: 
3 cJs, 2 $s, as given in illustration ; 6 from before middle of areole, 7 from end of 
areole; 10 from well before end of areole. 
1 d, 6 as above; 7 from end of areole; 10 from before end of areole. 
1 <$, 6 as above; 7 as above; 10 from end of areole. 
1 d, 1 ?, 6 as above; 7 from stalk 8, 9; 10 as above., 
1 <$, 6 from frd of areole; 7 as above; 10 as above. 
1 A, 6 as above; 7 as above; 10 from before end of areole. 
1 A, right wing. 6 from middle of areole; 7 shortly stalked with 8, 9; 10 from 
before end of areole. 
left wing. 6 free from angle of cell ; 7 on a long stalk with 8, 9 ; 10 anastomosing 
with stalk 7, 8, 9, to form the areole. 
This shows clearly that the position of vein 6 is of no use in separating the 
genus Antheua from Zana and Cleapa and perhaps other allied genera, as done 
by Sir George Hampson, and that the way in which vein 10 comes out of the 
areole is also far from constant. I do not think that any of these characters 
can be used for certain grouping of genera, as is done by Schaus in his paper in 
the Tv. E. S. L. 1901, p. 260.
