Some British Moths Described 
_ Acronycta rumicis: the Knot Grass (Plate V., Fig. 9 ; 
larva, Plate X., Fig. 9).—Also comes to sugar in June, 
and is very common everywhere. Expanse, 19 inches. 
The beautiful larva can be found in August and Sep- 
tember on all manner of roadside herbage, having, 
perhaps, a preference for Dock and Lady’s-Mantle 
(Alchemilla vulgaris). 
Diloba ceruleocephala: the Figure 8 (Plate V., 
Fig. 16; larva, Plate X., Fig. 10).—-A common species, 
widely distributed. The figure 8 on the wings is 
obtained by an apparent doubling of the orbicular 
stigma—a very unusual proceeding. It will be noted 
that these spot-like marks persist in one form or another . 
all through the Noctue. They are useful guides to 
identification, and by reference to Fig. 2, p. viii, the 
names and position of these spots will be learned. The 
moth is out in September. Expanse, 13 inches. The 
larva is found on fruit trees in May and June. 
Family LEUCANIIDA. 
Lucania conigera: the Brown Line (Plate V., 
Fig. 12).—Expanse, 14 inches. Comes to sugar and 
light ; it is also taken abundantly in some districts 
at flowers. The writer has taken thirty in twenty 
minutes at the bloom of Willow-Herb on an evening 
early in July. Larva on grasses from March to May. 
Leucania impura: the Smoky Wainscot (Plate V., 
Fig. 19).—It requires some little discrimination to 
identify correctly each member of the Wainscot family.
