140 THE GENERA OF BRITISH MOTHS. 
The genus Penthina. In this genus the perfect insects have the antenne simple, the thorax tufted, the 
anterior wings more than twice as long as broad, and in the front arching from the shoulder, There is but one 
British species, 
Penthina Satlicella (the White-back T, No. 4). This handsome species is not rare in favourable localities 
in the southern counties. The Caterpillar is described as dull reddish brown, with the head and next 
segment nearly black. It feeds in folded leaves of the Willow in May. The perfect insect appears in July and 
August. 
The Spilonotidi form the fourth sub-family of the Zortricide, and contain two genera, Pardia and 
Spilonta ; the last-named genus being subdivided into sections nearly.according with Hitbner’s genera, Hedya 
and Notocella, and Stephens’ Phaneta. 
The genus Pardia. The insect assigned to this genus have the palpi longer than the head, the antenne 
pubescent beneath, and the fore wings nearly twice as long as broad. The front of the fore wings is arched at 
the shoulder, and those of the males have a fold or crease as far as the middle. The Caterpillars are Rose feeders. 
There is but one British species. _ 
Pardia tripunctana (the Black-cloaked T, No. 5). This species is very common, especially in gardens 
and along road-side hedges. The Caterpillar (No. 6) feeds on the foliage of the Rose, and the perfect insect 
appears very abundantly in July and August. 
The genus Spilonote. The insects assigned to this genus have the palpi broadly compressed and longer than 
the head ; the abdomen tufted in the males ; the fore wings more than twice as long as broad, and deflexed when at 
rest ; the fold of the front wings reaches to the middle. The species, however, differ very considerably, and the 
genus has consequently been divided into sections, pretty nearly corresponding with Hiibner’s genera Hedya and 
Notocella, and Stephens’ genus Phaneta, as previously observed. The species selected for illustration is taken 
from the section edya, as best illustrating the character of the genus in general, the other two sections containing 
but one British species each. There are in all ten British species. 
Spilonta roborana (the Brown-cloaked 4, No. 7). This species is very plentiful and a great garden pest, the 
Caterpillar (No. 8) feeding upon the young shoots and buds of the Rose. The Caterpillar commences its ravages in 
April and May, and the moth appears in Jume and July. The other species in the first section (Hedya) are 
S. rosecolana (the Rose Brown-cloak T), 8. trimaculana (the Triple-blotched T), S. amanana (the Pretty 
Short-cloak T), S. neglectana (the Neglected Short-cloak 1), 8! dealbana (the White Short-cloak T) 
S. Alnetana (the Alder Short-cloak T), and S. Aceriana (the Maple Short-cloak T). In the second section 
(Notocella) the single species is S. ocellana (the Cream Short-cloak T), and in the third section (Phaneta) the 
single species is S. pauperana (the Early Short-cloak T). 
The fifth sub-family of the Tortricidae is composed of the Grapholithidi, This sub-family contains the 
following genera: Lithographia, Phleodes, Anchylopera, Bactra, Cartella, Hypermecia, Ditula, Pacilochroma, 
Halonota, Anisoteenia, Semasia, Coccyx, Heusimene, Panyplusia, Retinia, Carpocapsa, Opadia, Endopisa, 
Ephippiphora, Dicrorampha, Eucelis, Hemerosia, Grapholita, and Theodia. Many of these genera containing a 
great number of species, often of such divergent character as to render it necessary to divide the genera into 
several sections. 
The genus Lithographia. The insects assigned to this genus have the palpi longer than the head, and the 
anterior wings remarkably narrow, being nearly three times as long as broad. There are twelve British species, 
classed into four sections, all of which are subject to variation, especially Z. nisella (the Poplar Blotch-back T), 
of which there are seven or more varieties which have been ranked as species. 
Lithographia nigromaculana (the Beautiful Marbled T, No. 9). This pretty insect, with its anterior 
wings so brightly mottled with dark marks and specks upon a white ground, is very rare and yet widely dispersed, 
having been taken both in Ireland and Scotland, as well as in many parts of England. It appears about the 
end of July. 
The other species are, in the first section (Notocel?ia) L. Paykulliana (the Paykullian T); Z. nisella (the 
Poplar Bloteh-back T); Z. cinerana (the Mottled Gray T); Z. Campoliliana (the Recluse Marbled T), In the 
second section (Asthenia) there is but one species, L. minutana (the Brindled Marbled T). In the third section
