“Phaiaena Pavonia - ” 
Insects of the Lepidoptera order are 
divided into three genera Papilio 
Sphinx and Phala:na. Butterflies, 
Hawkmoths and Moths. The char- 
acters of the two former hereafter 
those of the Plialcena are. 
Generic Character. 
The Antennae setaceous, decreasing 
in size from the base to the apex. 
The wings when at rest are generally 
deflected. They fly in the night. 
Specific Character. 
Antennae feathered. No trunk. 
Wings expanded, horizontal, rounded 
entire, with a large eye in the centre 
of each; the first red -brown waved; 
the second orange. The antennae of 
the male are broader and the wings of 
the female larger, waved with black 
and white and bordered with yellow. 
Caterpillar green or yellow, spinous ; 
on thorns and brambles. Length of 
the Moth one inch. JSerJcen, out. 
******* The singular prov- 
ision which nature makes for the pro- 
tection of this fly deserves particular 
notice ; when the time of its contin- 
uation in the Caterpillar state is ex- 
pired, like all others it refuses to eat ; 
it then by much labour, forms a kind 
of bag or purse of a very tough sub- 
stance ; this it fixes aginst the trunks 
of trees &c, by a number of hairs or 
filaments which remain on the exter- 
nal surface. It lines the outer case 
by one of a finer texture, the top of 
which is closed by several bristles 
that unite in the centre exactly 
resembling a cap, and excludes almost 
the possibility of its receiving an in- 
jury during this defenceless state. 
In this bag it passes to the aurelia and 
remains till the birth of the perfect 
insect. * *
