ALARIA GAUR/E. 
PLATE XXIV. Fig. 4. 
Phal. Gaurso, Abbot and Smith, Lepid. Geoff., pi. 99. 
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.
