Antennae less than half the length of costa, Avilli clubs long and gradual. Eyes smooth. Forewin?; 
with vein 11 from subcostal before end of cell (in some troi)ical species vein 11 is anastomosed willi

base. IJindwing rounded, and (in all Australian species) with a i)rominent raised sexmark in the male 
between vein la and vein 2. (Fig. E.) 
Typk. Danaida plexippus Linne, from India. 
Ihis genus is of si)ecial interest on account of its immunity from the attacks of birds, and from tlis 
close resemblance to it of butterllies of non-iimnune suI)familios. A few species only occur in America 
and Africa, and one only in Europe: the great majority are confined to the Indo-Australian Region.
