Tur eighteenth Sub-Family of Geometride is that of the Acidalidi, containing eight British genera. The 
antenne of the males in all the genera are pubescent, the body stout, and the wings of moderate size. The 
Caterpillars are short, stiff, without humps, and having distinct lines. The Chrysalides are subterranean. 
The first genus is Zomaspilis, exhibiting all the leading characteristics above described. 
Lomaspilis marginata (the Clouded Border, No. 1), is the Pwcilophasia marginata of Stephens. The 
Caterpillar of this species (No. 2) feeds on the Sallow in June and October, the moth appearing in May and July. 
It is abundant everywhere. 
The genus Ptycopoda. The insects in this genus have the antennz very slender, and ciliated beneath in 
the males. The wings when at rest are extended horizontally. The hind tibize are furnished with a long brush of 
hair in the males, and from the structure of the feet Mr. Stephens divided the genus into two sections, The 
Caterpillars conceal themselves by day, and the Chrysalides are subterranean. 
Ptycopoda ornata (the Lace Border, No. 3). The Caterpillar of this elegant species is described by Freyer 
as being of grayish colour, with dark reddish lines on the back, and variegated at the sides with short 
irregular dark streaks. It feeds on different species of Thyme in April and August, and the moth appears in 
June and July. It is far from uncommon in chalky places in Kent and other counties. Tt has recently been 
taken in extraordinary abundance at Box-hill. There are five other species. 
P. Reversata {the Fan-footed Wave) is smaller than the preceding, of a pale ochreous tone, bordered with 
deeper. P. bisetata (the Treble Brown-spot) is somewhat larger than the last, but of the same colour, the dark 
band leaving a clear space next the edge. P. scutulata, P. Immutaria, and P. virgularia, are all of similar 
character, but none of them have the lacy effect of the border of P. ornata ; perhaps, however, A. virgularia, 
with its wings dusted with dark gray, has a somewhat lacy appearance, but the brownish colour is unfavourable 
to the effect. 
The genus Emmiitis. The single British species now assigned to the genus Zmmiltzs of Hiibner, has been 
recently separated from Mr. Stephens’ genus Ptycopoda. The generic distinctions which haye led to this change 
of location are too minute to require description in a popular work. 
Eminiitis rubricata (the Tawny Wave, No. 4) is placed by some entomologists in the genus Acidalia, The
