Some British Moths Described 
and mostly kept up by breeding. In some parts of the 
United States of America, where it was accidently intro- 
duced, it has proved a veritable scourge, and the 
Government have spent large sums in trying to exter- 
minate it. ‘The larva (Plate VI., Fig. 6) feeds on most 
kinds of trees during May. Moths out in July. Ex- 
panse, 14 to about 2 inches, 
_Psilura monacha: the Black Arches (Plate IV., 
Fig. 8).—A rather local species, While it only holds 
its own with us, it is occasionally a plague in other

fruit trees from May to July. The moth appears in 
August. Expanse, 14 to 12 inches. 
Dasychira pudibunda: the Pale Tussock (Plate IV., 
Fig. 9).—A common species, but confined to the South, 
where it is sometimes numerous enough to be destruc-

feeds on most trees and bushes during August and 
September. The moth is out in May and June. Ex- 
panse : male, 14 inches ; female, 2 inches. 
Orgyia antiqua: the Vapourer (Plate IV., Fig. 10;

and noteworthy little moth. The male flies during 
the day, and loves to dash about in the sunshine. 
There is not, however, much dash about the poor little
