The two black femicircles on the thorax and double row of trian. 
gular {pots at the ends of the pofterior wings, are mentioned as pecu- 
liar characters of this fpecies; the latter is, however, liable to con- 
fiderable variations, the {pots being in general, crowded ina con- 
fufed feries, and forming an irregularly interrupted line. It may be 
eafily diftinguifhed from Phalzna Aprilina by its fuperior fize, the 
colours are lefs vivid, and it is deftitute of the broad tranfverfe bar, 
which is confpicuous on the upper wings of Phalana Aprilina. 
The larva is fmooth, of an afh colour with fquare brownifh fpots. 
It feeds on the Oak.
