THE eighth sub-family of the Pyralide is that of the Tortricidi, forming a link between the present family 
and that of the Tortricide, the illustration of which we are about to commence. The sub-family of Vortricidi 
includes only two genera, Simuaethes and Nola, which while they begin to assume the general form of the true 
Tortrices, yet retain in their markings the character of Pyralide. This sub-family would appear, however, to 
require a more distinct title, as the same term, Tortricidi, is applied, in the system I am following, to the second 
sub-family of the true Tortricidae. 
The genus Stmaethis, The antenne of the males are strongly ciliated ; the palpi are porrected obliquely, 
and the tips straight. The body is short but not robust. The wings are short and broad, and when at rest form 
nearly a triangle and cover the hind wings. The Caterpillars have sixteen legs and feed in a white web on the 
leaves of various plants. The Chrysalis is formed in a firm white cocoon. There are four species. 
Simaethis Pariana (the Double-barred Nettle-tap, No. 1). The Caterpillar of this species (No. 2) feeds on 
the foliage of the Apple and Hawthorn, in June and August, forming its cocoon (No. 3) on the upper surface of a 
leaf. The perfect insect appears in July and September, and is abundant everywhere. 
The other species are, S. Fubriciana (the Nettle-tap) which is much darker, the hind-wings being as dark 
as the front, and traversed by a pale band ; S; Angustana (the Silver-dotted Nettle-tap), easily distinguished by 
its metallic spots ; and S. Vibrana (the Scarce Nettle-tap), which has the front wings brown, and towards the 
base tawny, with several transverse silvery lines, tinged with a pink or greenish flush. This species is very rare, 
but has been recently taken at Hurst, in Sussex. 
The genus Nola. The males have the antenne ciliated, the palpi rather long, and pointing downwards ; the 
fore-wings have three raised tufts of scales, the hind-wings are rounded and without markings. The Caterpillars 
are Lichen feeders. They have only fourteen legs and are thick and rather hairy. The Pupa is enclosed jna 
boat-shaped cocoon. Figures ‘of the transformations of this curious genus are engraved in Mr. Westwood’s 
Modern Classification of Insects. There are three species. 
Nola Cristulalis (the Least Black Arches, No. 4). The Caterpillar of this species, according to Hiibner, 
is whitish yellow with black lines, a little reddish at the sides. It feeds on the foliage of the Oak in May, and 
the Moth appears in May and June. It has been taken recently near Brighton rather abundantly, and sparingly 
in other places, especially in woody localities, but it is not common. 
The other two species are N. Strigula (the Small Black Arches), which resembles the preceding but is 
much darker, and N. Cucullatella (the Small Cloaked), which has the transverse band of the front wings more 
solid and of a darker tone, the entire base of the wings up to the first band being deep brown. 
The Tortricide helong to a distinct subdivision, the position of which with reference to the whole order 
may be stated as follows :—
