My last Plate brought to a close the great Family of the Geometride, with its nineteen Sub-Families and 
107 genera. The present Plate includes the next family, that of the Platyptericid, containing only three genera : 
also a portion of the following Family of Pyralide, to the end of its two first Sub-Families, the erminidi and the 
Cledeobidi.* 
FAMILY I.—Tur PLatryrrericips. 
This Family, the second of the third great Sub-Division, Lepidoptera Semidiurna, contains three genera of 
remarkable character, both in the preparatory and perfect stages. In the perfect state, from the singular form 
of the anterior wings, with their gracefully-curved hook, they have been thought by some Entomologists to display 
an affinity with the group to which the exotic Atlas Moth belongs. In the larva state, on the other hand, the 
singular Jacertine, or lizard-like form of the Caterpillars, led the great naturalist Latreille to unite them with the 
genus Cerwra, in a group which he termed Aposura. There are, however, certain links of character which appear 
to justify Mr. Stephens’ arrangement, in placing them next after the last of the Geometride. Such, for instance, 
as the breadth and slight texture of the wings, and the shortness of the legs, in the perfect insect, while the 
Caterpillars of the last species of the Geometride, those of Ennomos fiexuola, resemble in character those of the 
Platyptericide. The genera contained in this family are Platypteryx, Drepana, and Ciliz. 
‘The genus Platypteryz. In this genus the antenne of the perfect insect are bipectinated in both sexes. 
The fore wings are strongly hooked at the tip, beyond which is a deep indentation, followed by a corresponding 
prominence. They have also minor denticulations along the whole of the fringed edge. The hind wings are 
smooth at the edge, and rounded : the wings are extended horizontally when in repose. The Caterpillars have 
fourteen feet, the two anal ones being wanting, which allows the last segments to remain raised, giving them the 
tail-like appearance in which their general resemblance to the form of a small lizard consists. 
Platypteryx lacertinaria (the Scalloped Hook-tip, No. 1). The Caterpillar of this pretty moth (No. 2) 
feeds on the foliage of the Birch, and the moth, which appears from March to June, is not uncommon.
