AND THEIR TRANSFORMATIONS. 15 



Species 1. — Pericallia syringaria". — (Plate LIX., Fig. 21, and Plate LX., Fig. supr. fig. 29.) — 

 This elegant insect measures about H inch in the expanse of the fore wings, which are of a yellowish-gray, 

 varied with large paler patches on the costa, and an angulated violaceous striga towards the base, and two others, 

 which extend across the hind wings, suddenly angulated next the costa, where they are more approximate than 

 behind ; the first of these is brown, and the outer one pale violaceous, varied with brown beneath its subcostal 

 angle, there is also a violaceous patch near the tip ; hind wings more griseous, with some black spots on the anal 

 margin. The caterpillar is pale brown, with darker shades. It feeds on lilac, privet, jasmine, &c., and the 

 moth frequents gardens and woods, and is widely dispersed, although nowhere common.

ANGERONA, Duponchel. ENNOMOS, p. Boisduval. 

 Distinguished from the preceding by its weak body and very large wings, the anterior of which have the 

 margins entire and rounded, and the posterior slightly notched, the antennae slender and short, those of the 

 females being simple, and the palpi very short. The caterpillars are elongated, with two short conical tubercles 

 on the fifth and ninth segments, and the chrysalis is inclosed in a web amongst the leaves. 



Species 1. — Angerona prunariaP. — (Plate LIX., figs. 22 — 25.) — This common, variable, and conspicuous 

 species measures rather more or less than 2 inches in the expanse of the fore wings, which are of a fulvous or 

 orange colour, being brightest in the males, freckled with brown, and with a brown lunule in the middle of each 

 wing ; the base and extremity often also saturated with brown, varying greatly in its extent. The caterpillar 

 is also variable, being ferruginous, brown, or buflf, varied with paler markings, and the ead hand tubercle reddish. 

 It feeds on various trees, and the moth appears at the end of June, frequenting woods. A singular hermaphro- 

 dite specimen of this species is figured in the Transactions of the Entomological Society of France.

RUMIA, DopoNCHEL. ENNOMOS, p. Treitschke. 

 This species has the antennae of the males simply ciliated ; the palpi short, scarcely extending beyond the 

 front of the head ; the body slender ; the wings with the margins entire, except in the middle of the hind 

 ones, which are slightly angulated. The caterpillars have three pairs of abdominal prolegs, of which the two 

 anterior pairs are short and apparently useless (see fig. 27) ; the seventh segment with two elevated tubercles. 



Species 1. — Rumia crat.scata''. — (Plate LIX., Figs. 26 — 28.) — This species varies from IJ to 1| inch in 



the expanse of the wings, which are of a bright brimstone colour ; the costa of the fore ones marked at the base, 



before and beyond the middle, and at the tip, with ferruginous patches; from the second and fourth of these 



patches arise two slight dusky strigje of lunules (variable in intensity), and the third is connected with an oval 



patch of gray scales, bordered with rusty red ; the hind wings slightly marked with dusky. The caterpillars 



vary from fawn to gray, varied with white ; or brownish varied with deep brown ; the head orange, as well as 



the two anterior pairs of central prolegs. It feeds on whitethorn, sloe, &c. ; and the moth ajjpears in April, 



June, and August, and is very abundant.
