18 THE GENERA OF BRITISH MOTHS. 
The genus Pheosia has the antenne ciliated in the male, and simple in the female. It contains only two species, 
1. P. Dictea (the Swallow Prominent, Nos. 5 and 6), is by no means common, though it has been taken, 
on several occasions, near Dover, London, York, and other places. The Caterpillar is found on Poplar, Willow, 
and Birch, in June and October; the Moth appearing in June and August. 
2. P. Dicteoides (the Lesser Swallow Prominent) closely resembles the preceding, but is generally darker, 
especially the hind-wings, which are nearly brown. It is also smaller. The Caterpillar is said to be pale green, 
and glossy, with a slender yellow lateral line, and underneath tinted with rose colour, It is rather more 
rare than P, Dicteea. 
The genus Lophopteryx has the antenne pectinated in the male, and simple in the female. It contains 
three species. 
1. ZL. Caimelina (the Coxcomh Prominent, Nos, 7 and 8) is at the same time the commonest and handsomest 
species. The Caterpillar has been variously described. That in the Plate is from Hiibner’s figure ; but English 
entomologists describe it as greenish, with a yellow line along the spiracles, which are black, and each followed 
by a red spot, and having two tubercles on the twelfth segment tipped with red. It should be looked for in 
May and September, on Birch, Poplar, or Willow ; the Moth appearing in May and August. 
2. L. Cucullina (the Maple Prominent) is much smaller than the preceding, The ground colour of all 
four wings is a pale ochreous brown or buff, with a darker brown space towards the external edge, through 
which, in the front-wings, passes a narrow waved band of pale grayish white, spreading to a cloudy patch at 
the inner angle. In the hind-wings, a pale line of the ground colour passes through the deeper brown at the 
edge. The larva is green or pale reddish, with low humps on the middle segments, and a red-tipped double 
tubercle on the twelfth. 
3. L. Carmelita (the White-Spot Prominent) is nearly as large as LZ. Camelina, but may easily be 
distinguished by the difference of colour. The anterior wings are deep cool brown at the front, and grayish 
at the back, having two conspicuous white marks on the front edge. The larva is green; the surface being 
tuberculated with raised yellow specks. 
The genus Pterostoma contains only a solitary species. The antenne are pectinated in both sexes, but 
more strongly in the male. The palpi are of unusual length, as will be seen by reference to the figure. 
P. Palpina (the Pale Prominent) is represented at No. 9. The Caterpillar is without the humps or 
tubercles of the preceding genera, and is green, with several pale lines, and freckled with black along the 
back, ete. It is not rare, and is found in woods round London in May and September. 
Spatalia. In this genus the antenne are pectinated in the males, and slightly ciliated in the females. 
Spatalia Bicolora (No. 94). The only British species has been discovered since the first issue of this work. 
It was taken in the South of Ireland by Mr. Bouchore last summer (1858). A fuller description of this insect, 
and other novelties, will be given at the close of the second volume, accompanied by illustrations in a supple- 
mental plate. 
The genus Drymonia contains two species. The antenne are pectinated only in the male. 
1. D. Chaoniw (the Lunar Marbled Brown, No, 10) is distinguished from the other species by the 
presence of a dark spot in the centre of the light portion of the front wings. The Caterpillar is green, with 
yellow lateral and dorsal lines, and is found on Oak, Birch, and Hazel, in September ; the Moth appearing in 
May and June. It is rather rare, but its recent capture is recorded at Bristol, Epping, and other places. 
2. D. Dodonea (the Marbled Brown) is without the black mark alluded to in the preceding species ; all 
the bands of brown being less solid, and the whole colour much paler, except the markings near the base of 
the front wings ; in this respect, however, the specimens are very variable. The Caterpillar is pale green, with 
a gray dorsal line and blue head, and a yellow lateral line spotted with red. It is found in September, and the 
Moth in May and June, but is rather rare. The woods near London appear to be its favourite resort. 
The genus Petasia contained but one native species till the recent discovery of the handsome P. 
Nubeculosa in the Birch woods of Perthshire. The antenne are pectinated only in the male. 
No, 11 is the male of the Pelasia Nubeculosa (the Rannoch Sprawler), and No. 12 the female, drawn from
