Some British Moths Described 
sugar. In July it comes to flowers. A pest to farmers, 
and, as the larva works under the ground, the damage 
it is doing is not always immediately apparent. Corn, 
Hay, and Turnip roots, are alike destroyed. 
Agrotis exclamationis: the Heart and Dart (Plate 
VIII, Fig. 13).—Expanse, to 14 inches. Quite a 
common moth everywhere at sugar from June to 
August. Larva a root feeder attacking Grass, Turnip, 
etc., and I have found it in the heart of a Cabbage, It 
is found from September to May. 
Agrotts tritici: the White-Line Dart (Plate VIIL., 
Fig. 14).—The genus grotis is a big one, containing 
many variable species, and Tritici mimics about half of 
them, so that it becomes rather difficult at times to dis- 
tinguish them. Once I saw 77itici in thousands at Rag- 
wort bloom on the sand-hills near the Mull of Kintyre, 
and the variations seemed to be endless, many of them 
very striking and beautiful, and very far removed from 
the type. August was the month. Larva at the roots 
of various shore plants in June and July. 
Agrous strigula: the Lovers’ Knot (Plate VIIL, 
Fig. 15).—Expanse, to 14 inches. A very pretty little 
moth commonly found sporting over Heather in day- 
time. By beating the Heather either late in autumn or 
early spring, the larve can usually be had in some 
numbers, It is not difficult to rear, 
Agrotis precox: the Portland Moth (Plate VIIL., 
Fig. 16).—Fairly general wherever there are extensive 
sand-hills, at Ragwort flowers, from July to September. 
The larva feeds on various low plants on the shore,
