Some British Moths Described 
VIII., Fig. 19).—Expanse, to 14 inches. Widely dis- 
tributed and very common, especially at sugar. The 
main brood appears to occur in June, but good speci- 
mens turn up at sugar all through the summer. ‘The 
larva hibernates, and may be had, like many of its tribe, 
feeding on various low plants in the spring. 
Noctua festiva: the Engrailed Clay (Plate VIIL., 
Fig. 20).—Very common and variable. Comes freely 
to sugar in June and July. Where bunches of Heather 
overhang rocks or banks, get your net well under the 
roots, and shake them over it. You can always get 
some larvee in this way, and if the month is May you 
can be pretty sure N. festiva will be amongst your 
captures. It is of a beautiful dark brown, with black 
zigzag lines on the back (see Plate II., Fig. 7); will 
eat a number of plants, but Heather varieties, and 
especially those from the hills, are distinct and dark. 
Expanse of moth, 1+ inches. 
Noctua zantographa: the Square - Spotted Rustic 
(Plate VIII, Fig. 21).— Common enough to be a 
nuisance during the month of August, At light, flowers, 
sugar, or working with the net, every second insect is sure 
to be the Square Spot. If you see Primroses in May 
ragged and bitten, with buds half consumed, if you 
look under the outer leaves during the day or examine 
the flowers by lamplight, the culprit can be caught 
“‘ red-handed.” It may be some other species, but the 
chances are it will be the larva of Zantographa. It is 
reddish clay-colour, with light lines on the back and a 
dark one along the sides. Expanse of moth, 14 inches.
