Plate VII. Figure 2. 
This plain and yet beautifully-marked fly, which de¬ 
rives its name from its spotted appearance, measures 
across from a little over two to nearly three inches. 
Male: front wings semi-transparent and pure white, 
thickly spotted over with fine clear blue-black spots with 
a tinge of green. Hind wings white, similarly marked, 
but the spots much fainter in colour. The thorax, which 
is also white, has six large blue-black spots, three on 
each side, in a row, the body ringed with bands of 
bluish black. The spots in the female are less bright 
than in the male. She is of very much larger size, the 
superior measurements given above belonging to her. 
Localities for this species are York, Bromsgrove, Hyde 
Park, St. James’s Park, and other parts near London, 
Cambridge, Exeter, Lewes, Blandford, Birmingham, &c. 
The date of the appearance of the perfect insect is 
in July. 
The caterpillar is pale yellow, with a u good few ’’ 
shining black spots, slightly raised. The head has two 
black spots, and the first segment behind it is also black, 
as is likewise the tail one, so to call it. 
The date of the appearance of the caterpillar is iu 
October, and thence on, I believe, till April or May. 
It feeds on the wood of a variety of trees, the elm 
chiefly, but also the apple, pear, lime, birch, beech, 
walnut, horse-chesnut, ash, and hazel.
