CLASS VIII. 
of Lepidoptera, so that there may be observed, principally among the 
exotic genera, some that recall the genus Pieris, others Papiliones (or 
Lquites), not in habit alone, but also in colour. Perhaps a parallel series 
is formed by the Phalene, comparable with most of the genera of diurnal 
Lepidoptera. Other exotic Phalenw approach more nearly to the genus 
Urania, but yet amongst European species Phalena sambucaria presents 
an analogy with it. |

Stuk, Tab. xx1. the black-sprinkled moth, Panz. Deutschl. Ins. Heft 31, 
Tab. 24; with long, small, round wings, outspread, 2” broad, length of body 
usually 9’’’, the abdomen thicker and more unwieldy than in most species 
of this division ; wings and body yellowish-white, with many black spots 
and points ;—Phal. sambucaria L., Acena sambucaria TREITSCHKE, Oura- 
pteryx sambucaria LEACH, R@SEL, Ins. 1. Pap. Noctwrn. Cl. 11. Tab, VI. 
Sepp, Nederl. Ins. 1. 6e Stuk, Tab. 1., one of the largest European species, 
but of a totally different form, with broad wings, the anterior falcate at 
the apex, the posterior excised at the margin with obtuse angles, of which 
angles the third is produced into a short tail; the general colour pale 
sulphur-yellow, with two light brown bands on the fore-wings, and one 
similar on the hind-wings, which is a continuation of the innermost 
of the former. The eggs are prettily ribbed; the caterpillar is a true 
spanner, of a brown colour, resembling a dead twig. Phal. defoliaria L.,

Platypteryz LESPEYRES, OCHSENH., Drepana SCHRANK. Wings, 
the insect at rest, patent, anterior broad, in some rotundate, in most 
faleate. 
Palps short. Antenne in males pectinate, in females 
setaceous or serrate or very shortly pectinate. Ocelli none. Cater- 
pillars with fourteen feet, terminated by apex acute, erect, the anal 
feet wanting. 
Sp. Platypteryx faleula, Phal. (Geometra) falcataria L., LYONET, Ouvrage 
posth. Pl. 35, figs. 6—10; Platypt. hamula, Phal. falcata FaBR., SEpp, 
Nederl. Ins. 11. 4¢ Stuk, Tab. xvi. The one-tailed caterpillars resemble in 
some degree in miniature the two-tailed caterpillars (Bombyx vinula, 
furcula ;) whence some writers have placed them with the Bombyces 
(Verzeichniss der Schmetter. der Wiener gegend, p.64, HUBNER, LATREILLE) ; 
Liny2zvus and Fapricius, giving their attention exclusively to the per- 
fect insect, placed the species known to them amongst the Phalene 
geometre, with which indeed they have a greater affinity. The point in 
which the body of the caterpillar terminates behind forms a supernumerary 
segment (a thirteenth ring), which represents the two hind-feet that are 
wanting. 
Noctua Fabr. Tongue distinct. Palps in most moderate, with 
third terminal joint more slender than the preceding or small.
