Aut the Moths in this Plate are of the family Bombycide, with the exception of the Lymantria Monacha, 
which belongs to the Arctiide, For the sequential arrangement adopted in the British Museum, see page 16. 
The genus now called Zymantria is the Psilura of Stephens, Hiibner’s original name having been eventually 
preferred. This genus, though seemingly allied to some recently described, is yet in some respects very distinct, 
as in the elongated abdomen and oyipositor of the female ; also in the habit of leaving the eggs uncovered after 
they are deposited, instead of covering them with the fur taken from the body of the parent. 
Lymantria Monacha (the Black Arches, No. 1) is the only English species. It is a remarkably handsome 
insect, and is by no means rare, especially in the south of England. The male has the antenna strongly bipec- 
tinated ; the female (No.2), which is much larger, having them simply ciliated. The Caterpillar (No. 3) feeds 
upon Scotch Fir, Bramble, Birch, Apple, ete., and is found in June and July ; the Moth appearing in August. 
The genus Odonestis is distinguished by the long and pointed palpi, which haye the appearance of a kind 
of beak ; also by the gently waving external margin of the anterior wings and their pointed extremity, and by 
the disparity of the male and female ; the male being much smaller and with a tufted tail, while the body of the 
female is much more robust and not tufted. The antenne of the male are very strongly, while those of the female 
are but slightly, bipectinated. There is but one English species. 
Odonestis Potatoria (the Drinker-Moth, No. 4) is a very handsome and very common insect ; the conspicuous 
Caterpillars being found on every bank as soon as the grasses and other spring foliage appear, to furnish it with 
suitable food. The’male (No, 4) is much more richly coloured than the female ; while the female (No. 10) has 
the advantage in size. In rearing broods of Caterpillars, female specimens are obtained much more frequently 
than males. The Caterpillar (No. 6) is full grown in June, and the Moth appears in July. 
The genus Clisiocwmpa has received its name from the gregarious nature of the Caterpillars, the term being 
formed of two Greek words, which have reference to Caterpillars of that habit. The two English species are 
both popularly termed Lackey-Moths, in allusion to the gay colouring of the larvae, which are striped with lines 
of many colours, like the lacings of a rich livery. The females of this genus arrange their eggs in the form of 
_ bracelets of small beads round the branches of trees, the foliage of which forms suitable food for the Caterpillars. 
The males have the antenne pectinated, the females only ciliated. There are two British species. 
Clisiocampa Neustria (the Common Lackey-Moth, No. 7) is very abundant everywhere, though not often 
seen, as it is almost exclusively a night-flyer, and is remarkably swift on the wing, The Caterpillars are, 
however, but too frequently seen in our gardens, where they are most destructive, and the best way of obtaining 
good specimens of the perfect insect is to rear them from the larva, The female is rather larger than the male,
