Tue third Sub-Family of the Zortricid@ is composed of the Penthinidi, containing three genera, Brachytenia, 
Antithesia, and Penthina. 
The genus Brachytenia. The insects assigned to this genus have the antenna slender, but setaceous, and 
clothed beneath with scales. The anterior wings are nearly, but not quite, twice as long as broad. The waving 
of the bands is very marked, and angular. Some of the larve feed within the shoots of Sallow. There are two 
British species. 
Brachytenia Hartmanniana (the Short-barred White, No. 1). This pretty species appears in July and 
August, and is found on the trunks of Willows, &c., near London, but is considered scarce. 
The other species, B. semifasctana, may be easily distinguished by its generally darker colour, and th 
nterruption of the principal band, or fascia, which only extends half across the fore wings. 
The genus Antithesia. In this genus the perfect insects have the palpi longer than the head, the thorax 
tufted, and the anterior wings rather more than twice as long as broad. The front of the wing is arched from the 
shoulder. There are fourteen British species, in one ‘of which the sexes differ so considerably in their markings 
as to have been taken for distinct species. 
Antithesia gentianana (the Gentian T, No. 2). This species belongs to the second division of this 
extensive genus, the insects assigned to which correspond closely in character with those of Stephens’ genus 
Endothenia, while the first division have rather more affinity with those of Hiibner’s genus Apotomis. The 
species (A. gentianoides) gives a fair general idea, however, of the whole of the genus. It is said to be common 
near London. The Caterpillar (No. 8) appears in November and March, and is generally found in heads of the 
Teazle. The perfect insect appears in July, and is common in the south of England. 
The other species are A. corticana, A. Betuletana, A. Capreana, A. ochrolewana, A. prelongana, 
sororculanda, A. cynosbatella, A, Pruniana, A. dimidiana, A. swuciana, A. Grevilliana, A. Scllanana, and 
A. marginana. The two last, like gentianoides, belonging to the section Endothenia,
