Tue eighth Sub-Family of the Noctwide, the Bryophagidi, comprises only one British genus, Bryophila. The 
genus Bryophila is well distinguished from other genera of Noctuide by the smaller and more delicate forms of the 
species which it includes, only two of which are British ; these bave slender and simple antenn in both sexes, 
the palpi are raised upwards, the abdomen is slight, and crested above, and the wings are rather brond. The Cater- 
pillars are slender, and more or less covered with pilose tubercles. They feed on various Lichens. 
Bryophila Perla (the Marbled Beauty, No. 1) is the smallest of the two species. It is extremely variable, 
both in the distinctness of the markings and the intensity of the ground colour of the wings. The hind wings are, 
however, generally pale. The Caterpillar feeds on Lichens growing on trees or walls, and the Moth may be 
found in July and August settled upon old walls or palings. It is a very common species. 
Bryophila Glandifera (the Marbled Green), the other species, is generally rather larger than Perla, and 
may also be distinguished by the full brown tone of the hind wings; it is, however, very variable. The Caterpillar, 
which is greenish, with dark and white stripes, is also a Lichen feeder. The perfect insect appears rather earlier 
than Perla, being often found in June, but also in July and the beginning of August. It is common, but does not 
appear to be quite so abundant as the preceding species. 
The ninth Sub-Family are the Noctwo-Bombicidi, of which there are three genera, Ceratopacha, Cleoceris, and 
Engramma. : 
The genus Cerafopacha. In this genus the insects are distinguished by the form of the fore wings, which are 
either obtuse or angulated; the antennx are thick and short, but simple in both sexes, though pubescent beneath ; 
the palpi are horizontal, with the last joint long and slender; the abdomen somewhat slender, and not crested. 
The typical larvae are rather large-headed, smooth, and rather flattened beneath. They feed on various trees, between 
leaves webbed together. There are seven British species. 
j Ceratopacha Fluctuosa (the Satin Carpet, No. 2) is not a common insect, but is not unfrequently taken in 
woody districts of the southern counties, and has also been taken in the lake district, at Huddersfield, Tenterden 
and Worcester. The Caterpillar is yellowish white, with a dark head, and feeds on Birch. The Moth appears 
about the end of June. 
Ceratopacha Flavicornis (the Yellow-Horned, No. 3) was formerly considered a rare species, though taken 
occasionally in the woods round London. It has, however, recently been taken abundantly near Manchester, and in 
some plenty at Brighton and Bristol. The Caterpillar (No. 4) feeds on Birch, rolling up the leaves. The perfect insect 
appears in March and April. 
The other species are—C\. Dupiaris (the Lesser Satin Carpet), a pretty little species, the fore wings of which 
are pale gray, with numerous darker waved bands. The hind wings are very pale brown, with a light band across 
the middle. C. Diluta (the Lesser Lutestring), a pale toned species, with two groups of bands across the fore wings, 
and other marks. C. Or (the Poplar Lutestring), a larger and darker coloured species, the ground keing dark gray, 
and the bands and markings dull brown. °C, Ocularis (the Figure of Highty), at once distinguished by the marks , 
or stigmata, in the centre of the fore wings, which are white, filled up with black, and resembling the numerals 80. 
And, lastly, C. Ridens (the Frosted Green), which is a very distinct species ; the ground colour of the fore wings
