38 THE GENERA OF BRITISH MOTHS. 
The other species are 7. Subsequa (the Lunar Yellow Underwing), 7. Orbona (the Lesser Yellow Underwing), 
T. Interjecta (the Least Yellow Underwing), and 7. Janthina (the Lesser Broad Border). The commonest of these is 
7. Orbona, and the rarest T. Subsequa. 
The genus Thalpophila is very closely allied to Triphena, both in its preparatory and perfect states, on which 
account the insects now belonging to it were separated from the genus Polia, where they had been located by 
Ochsenheimer, and placed next to Triphena, 
Thalpophila texta (the Straw Underwing, No. 5) is the only British species. The Caterpillar is pale grey, 
darker on the back ; it feeds on the goat’s-beard and other plants in spring and autumn, and the Moth, which is very 
rare, appears in June and July. 
The genus Segetia, like the preceding, has also been brought nearer to Triphena by recent arrangement. 
The antenne of the males are strongly ciliated. 
Segetia Xantographa (the Square-spot Rustic, No. 6) is a common Moth, and appears in August. The Cater- 
pillar, is pale, dirty yellow, with a lighter line on each side, and feeds throughout the winter. There is only one 
British species. 
The genus Rusina is remarkable among the Noctwide for its deeply pectinated and Bombyx-like antennx. 
Rusina ferruginea (the Feathered Rustic, No. 7) has received its popular name from the full feathering 
antenns so unusual among the allied genera. The Caterpillar is dusky brown with pale stripes. The perfect 
insect has been taken in July near Darenth and at Wimbledon, but is rare, and is the only British species. 
The genus Lytew has the antenne somewhat robust, and distinctly ciliated in the males, the two species 
differing, however, considerably in this respect. 
Lytaa Umbrosa (No. 8) is known as the Six-striped Rustic, from the number of rather distinct bands by which 
the fore wings are traversed. The Caterpillar is greyish white, with a dusky stripe, and is to be sought in the 
spring and early summer, the perfect insect appearing in July and August. It is rather rare. 
The genus Cerapteryz is distinguished from the preceding genera by the smaller size of the Moths, the 
light coloured stripes which follow the direction of the veins on the anterior wings, and several anatomical distinc- 
tions too technical for detail in a popular work. 
Ceraplerye Graminis (the Antler, No. 9) occasionally appears in great numbers, especially in mountainous 
districts, the larvae committing great ravages among the roots of the grass, by which whole meadows are some- 
times destroyed. The Moth appears in July and August.
