on sloe, but does not mention it further ; and I am unable to find 
any account of its habits or appearance in other works.

Expands 0'87 to 1‘12 in. Wings brownish black. The fore 
wings in the female and sometimes in the male exhibit faint traces 
of a brownish orange band running parallel to the hind margin. 
The hind wings have a short tail something like that of T. Spini, and 
parallel to the hind margin is a row of well-defined semilunar spots 
of an orange-brown colour, decreasing as they approach the costa. 
The colour of the under side is paler than that above. The fore 
wings have a blnish white interrupted line running from the costa 
to the inner margin. The hind wings have a similar line which 
does not assume a W-shape. The hind margin has an orange band 
bordered with bluish white, and having a row of black spots, one 
being placed in each inter-nenral space. Fringes black. Antennae 
black, ringed with white. 
Time of Appeakange. — June. 
Habitat. — Woods in Central Europe (including England), 
Northern and Central Italy, and Dalmatia. It also occurs in 
the Altai. 
Laeva. — Similar in shape to those of the allied species. 
“ Green, darker on the back ; two rows of long yellow spots on the 
back, and a row on each side above the legs ; six long oblique 
yellow stripes on each side” (Stainton, from Diiponchel). “The 
chrysalis is attached by a belt and by the anal extremity ; it is 
obese, blunt-headed, and hump-backed ; and has a niedio-dorsal 
series of five rather conspicuous warts or tubercles” (Newman, 
from Hulmer). The larva feeds on the leaves of Prunus Spinosa, 
on the twigs of which the eggs are laid in the summer and remain 
all the winter, the larva ap])earing in May.
