DICHROMA HISTRIONALIS. 
PLATE XXX. Fig. 2. 
The head is white, with a patch of fulvous on the 
crown ; the thorax white, ornamented with fulvous. 
The fore wings are of a splendid golden fulvous 
hue, ornamented with many silvery white marks, 
strongly relieved by being edged with black scales ; 
the fore margin of the wings is also white. At the 
base of the fore wings are two divergent white bars, 
the anterior of which is strongly forked ; the upper 
bar of the fork abbreviated and succeeded by an 
oval patch ; across the middle of the wing, in an 
oblique direction, are four oval white patches, the 
anterior being, as it were, duplicated ; then follows 
an oblique white bar, broken in the middle, from 
the outside of which several straight white bars 
extend to the outer margin of the wing. The hind 
wings and abdomen are of a silvery white, slightly 
shaded with brown. 
The expansion of the fore wings is twelve lines 
and a half.
