of Lepidoptera, so that there may be observed, principally among the 

 exotic genera, some that recall the genus Pieris, others Papiliones (or 

 Equites), not in habit alone, bat also in colour. Perhaps a parallel series 

 is formed by the Phalcence, comparable with most of the genera of diurnal 

 Lepidoptera. Other exotic Phalienai approach more nearly to the genus 

 Urania, but yet amongst European species Phalcena sambucaria presents 

 an analogy with it.] 



Sp. Phalcena betularia L., Amphidasis betularia TREITSCHKE, SEPP u. 40 

 Stuk, Tab. xxi. 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., Acccna sambucaria TKEITSCHKE, Oura- 

 pteryx sambucaria LEACH, ECESEL, Ins. I. Pap. Nocturn. GL in. Tab. vi. 

 SEPP, Nederl. Ins. I. 6e Stuk, Tab. I., 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., 

 Fidonia defoliaria TREITSCHKE, ECESEL in. Tab. Xiv. (the metamor- 

 phosis and the wingless female), Tab. XL. fig. 6 (the perfect male), SEPP,

Platypteryx LESPEYRES, OCHSENH., Drepana SCHEANK. Wings, 

 the insect at rest, patent, anterior broad, in some rotundate, in most 

 falcate. Palps short. Antennas 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 falcula, PJwl. (Geometra) falcataria L., LYONET, Outrage 

 posth. PI. 35, figs. 6 10 ; Platypt. hamula, Phal. falcata FABR., SEPP, 

 Nederl. Ins. u. 40 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 ombt/ces 

 (Verzeichniss der Schmetter. der Wiener gegend, p. 64, HUBNER, LATREILLE) ; 

 LINN^US and FABRICIUS, giving their attention exclusively to the per- 

 fect insect, placed the species known to them amongst the Phalcence 

 geometrce, 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.
