ALARIA GAURiE. 
PLATE XXIV. Fig. 4. 
Phal. Gaurae, Abbot and Smith, Lepid. Geog., pi. ^9. 
This delicately tinted moth has some relation to the 
preceding, but seemingly not so close as to warrant 
its being included under the same generic appella- 
tion. The ground colour is white, the wings tinted 
with red, that colour deepening at the exterior 
margin of the upper pair, and forming a transverse 
band beyond the middle not reaching to the hinder 
extremity ; thorax crested, inclining to yellow. 
The caterpillar (fig. 5) is rather long and slender, 
having sixteen feet; the under side of the body 
and legs white, the rest yellow, each segment with 
a transverse black band in the middle ; head ferru- 
ginous. It feeds on the Gaura biennis. When the 
moth settles on the blossoms of that plant, there is 
such a similarity between its colours and those of 
the flowers, that it is scarcely possible to distinguish 
them at a small distance.
