110 THE GENERA OF BRITISH MOTHS, 
Clematis vitalba, from which its specifie name is derived. The perfect insect appears both in June and 
October. It has been taken in plenty at Bristol and Cambridge, and more sparingly in other places. 
There are three other species: P. tersata (the Fern) is rather larger and of more dusky brown, with 
the transverse bands passing evenly across the wings. P. lignata is a smaller and rather more delicately 
formed insect, which may be readily distinguished by two short but strong stripes, and three slenderer but 
longer streaks on the hind wings. P. polygraminata (the Many-lined) is grayish in tone, with rather irregular 
brown bands, one of them running transversely and terminating towards the centre of the wing; and within 
the dark bands are others of a whitish tone. 
The genus Plemyria of Hiibner has been adopted for the purpose of locating more appropriately two 
British species, removed from the last described genus. The insects assigned to the genus under description 
have the antenne simple in both sexes ; but the bodies are without the spots which distinguish those 
retained in the last. 
P. gemmata (the Narrow-barred Carpet, No. 5), formerly Phibalapteryx angusta, is an inconspicuous 
insect, and was supposed by sonre collectors to be an imported insect, as the specimens found in the State 
of Georgia in North America are identical with those considered British. It has however occurred recently 
at Brighton, Bristol, in the Isle of Wight, and other places. The Caterpillar is unknown. 
The second species, P. lapidata, closely resembles the last described, but has the wings rather more 
pointed and the waved transverse lines more distinct. It is very rare, having only been taken at Rannoch 
in Perthshire. 
The genus Philereme of Hiibner is now made to contain the insects assigned by Stephens to his own 
genus Scofosia, in consequence of the priority claimed for the term adopted by the German Entomologist. 
The insects have the antenne simple in both sexes, the abdomen of the male is tufted, the wings are 
slightly dentate, and in some species the hind wings have a tuft of scales near the terminal angle. The 
Caterpillars are thick, and feed at first in folded leaves. The Chrysalis is formed in the earth, There are 
two British species. 
Philereme Rhamnata (the Dark Uiber, No. 6), is a much larger insect than any yet deseribed in 
this sub-family. The Caterpillar, which is described by Hiibner as variable, is usually dark brown on the back, 
and white, speckled with brown, at the sides; or green, with a white line at the side, edged below with dark 
reddish brown. It feeds on the foliage of the Buckthorn. The moth appears at the end of May, and is found 
in woods; but is not a common species. It has been taken recently near Brighton, Bristol, Lewes, York, 
and other places, 
The genus Schidav. This genus of Hiibner’s has heen adopted for the reception of a single species, 
lately located in the genus Scotosia as Scotosia Sparsaria, The antenne of the male are simple; the body is 
rather longer than the wings; the palpi extend beyond the head ; and the hind wings slightly dentate. The 
Caterpillar has not been described. 
S. Sparsaria (the Broom Scallop, No. 7) is an inconspicuous insect, not likely to be much sought except 
by thorough Lepidopterists, especially as it is very rare, having only been taken in the New Forest and near 
Cambridge. It appears about June. 
The genus Triphosa. The insects assigned to this genus have the antennae simple in both sexes. The 
palpi form a short beak, The wings are broad, and generally strongly marked with transverse bands, which 
are conspicuously sinuated or sharply dentated. The Caterpillars are robust, and marked with pale stripes. 
Triphosa dubitata (the Tissue, No. 8), is a rather large and handsome insect. The Caterpillar feeds 
on Buckthorn, and is described by M. Guénée as being green with white lines, and a yellow line at the side. 
There are two broods, the Moth appearing both in May and August. It frequents gardens, and is a common 
and widely-distributed species. 
The other species, 7. certatu (the Scarce Tissue, No. 84), may be known by its rather smaller size, and 
deeper and redder colowy, especially in the hind wings, and the lighter band of ochreous tone in the front wings. 
The genus Camptogramma. The insects assigned to this genus have the antenne simple in both sexes. 
The wings are broad, like those of the last genus, and have similar markings ; but their surface is entirely without
