SCARLET TIGER-MOTH.

each of them ornamented mth about a dozen cream- 
coloured or yellowish spots of various dimensions, 
the two largest placed rather beyond the middle. 
The secondary wings are of a fine carmine-red, 
ivith three large and irregular black sjiots; the 
fringe of all the ivings black. The thorax is black 
glossed with green, and marked with two yellow 
longitudinal spots : abdomen the colour of the un- 
der ivings on the surface, the under side, basal 
segment, and a dorsal line, black ; the under side 
highly glossed with green. Several varieties occur, 
of which the most remarkable are those iu which 
the red colour is replaced by pale yellow, and such 
as have the abdomen entirely black, and the under 
ivings dull brown, without any vestige of the gay 
colouring of ordinary specimens. This latter variety • 
is represented on Plate xix. fig. 4. 
On issuing from the egg, the caterpillar is of a 
dirty yellow, with the head and numerous small 
spots over the body black. After its first moult 
it becomes black, ivith three yellow lon^tudinal 
lines, one on the back and another on each side ; 
the black portion with many small blue tubercles, 
from which issue diver^g greyish hairs. The 
moth appears in June ; but is not of frequent oc- 
currence in this country. It has been found in 
some plenty in the vicinity of Cambridge and in 
Darenth Wood; also, but much more sparingly, at 
Blackheath, Oxford, near Reading, &c.
