I J, inches. Common in most parts of Europe from May to September, according to the locality. 

 The larva is reddish-brown, varied with whitish, and may be found on fir from September to 

 April, and again in June and July. 



2. E. Pinicolai'ia (Bell.). — Glaucous-green, fore-wings more pointed than in Prosapiaria, with 

 two pure white stripes bordered with reddish-brown, running from the inner margin two-thirds of 

 the distance to the costa, the innermost very oblique. Hind-wings with one line. Expands 

 about 1^ inches. Inhabits larch forests in Corsica. 



GENUS II. — METROCAMPA (LATR.). 



Body moderately stout, fore-wings broad, with the hind margin convex, and as long as 

 the inner margin, with two dark transverse lines bordered with white, the second continued on 

 the hind-wings ; antcnn;^' of the male pectinated. The larvae have twelve legs, with fleshy 

 filaments on the sides, and a round head. They feed on trees from September to May, and

*i. AI. Alargaritaria (Linn.), {Light Emerald). — Wings very light green, the fore-wings 

 not dentated, with two white transverse lines, bordered with darker green, and converging 

 a little on the inner margin ; hind-wings slightly dentated, with a white line across the 

 middle. A reddish variety of this species has been met with, but very rarely. The type is 

 common in Central and Southern Europe. The larva is dark green or brown, with darker 

 lines on the back and sides. It feeds on oak, beech, &c. The moth and larva are figured at 

 PI. 43, Fig. \,a,b.

 with two indentations above the middle ; hind-wings rather long, with the costa long ; the 

 antennae of the male very shortly pectinated ; femora hairy. The larvse have fourteen legs, 

 and a hump on the I2th segment, and change to pupae in moss. The only European species, 

 *0. Bideniata (Clerck.), has greyish-brown or yellowish-brown fore-wings, with two dark brown 

 transverse lines, the second dentated, and bordered with whitish behind ; hind-wings paler, with 

 a dark transverse line beyond the middle. There is also a dark brown ring in the middle of

GENUS IV. — EUGONIA (HUBN.). 



Middle-sized moths; the body stout, the wings strong, yellow, and often dusted with darker; 

 the fore-wings excavated below the tips, and curved below the succeeding prominence, and
