as that of M. Noiata. The larva is yellowish-green, with a darker line on the back, bordered 

 with }'enow, and with yellowish lines on the sides. It lives on fir. 



5. M. ALstiniaria (Hiibn.). — Wings varied with brown and grey, and finely dusted with 

 darker ; fore-wings with blackish transverse lines, the outermost acutely angulated below the 

 costa, and broadly bordered with whitish ; the concavity of the fore-wings and the angle of 

 the hind-wings very slight indeed ; hind margin dotted with black on the fore-wings, and edged 

 with a black line on the hind-wings. Inhabits South Europe, and Northern and Western Asia. 

 The larva is dull pale green, with white lines on the back and sides. It feeds on tamarisk. 



GENUS XVI. — URAPTERYX (LEACH). 



Body slender ; fore-wings with the borders straight and the hind margin nearly rectangular ; 

 hind-wings with the inner margin longer than the costa, and a long pointed projection in the 

 middle of the hind margin. The larva is slender, with bud-like elevations on the sides of the 

 8th and on the back of the nth segments. It constructs a cocoon of loose threads, inter- 

 woven with leaves, and attached to a branch. The only European species, * U. Sambiicaria, 

 Linn, (the Swalloio-tailed Hloth), is pale citron-yellow ; the fore-wings with two pale olive-brown 

 transverse lines, the hind-wings with one line, which runs towards the anal angle, and with two 

 small yellowish-brown spots at the root of the tail. Expands from if to 2 J inches. Common 

 in Central Europe, and Northern and Western Asia in June and July. The larva is brown, 

 with paler and darker stripes, and feeus on elder, honeysuckle, lime, &c., from autumn to May. 

 The moth is figured at PL 43, Fig. 6. 



GENUS XVII. — RUMIA (DUP.). 



Slender; fore-wings rather long, with the inner margin long; hind-wings rounded, 

 longer on the costa than on the inner margin. The larva is thick, with fourteen legs, the two 

 first pairs of prolegs rudimentary, with humps on the 7th segment, and with slight projections 

 on the sides of the four last segments ; it undergoes its transformations in a cocoon. The 

 only species, * R. Lnteolafa, Linn. [Cratcsgata, Linn. ; the Brimstone iMoth), has sulphur- 

 yellow wings with transverse rows of suffused lunules, the fore-wings with rusty-red spots at 

 the base and middle of the costa and before the tips, and with a white central lunule, 

 bordered with brown. Expands from i\ to il inches. Common throughout Europe, Northern 

 and Western Asia, and North Africa. There is a succession of broods throughout the year, 

 and the larva, which is brown or green, with pale spots on the sides of the 3rd, 

 iith, and 12th segments, feeds on sloe and hawthorn. The moth and larvae are figured at 

 PL 44, Fig. 2, a, b. 



GENUS XVIII.— ANGERONA (DUP.). 



Body slender, wings broad, hind margin of the fore-wings a little oblique, and the tip 

 rectangular ; the costa and inner margin of the hind-wings of equal length. The larva 

 resembles a twig, and has pointed protuberances on the 9th, and smaller ones on the 5th, loth, 

 and 13th segments, and the head is smooth and round. It undergoes its transformations 

 between leaves spun together. The only European species, *A. Prima ria, Linn, (the Orange 

 Moth), is orange in the male and pale yellow in the female, with fine violet-grey transverse 

 dashes, and oblong central spots. In the variety Sordiata (Fuessly) the dashes are fused 

 into broad basal and marginal bands, leaving only the central area orange. Expands from
