Pekicallia — Him ERA — Crocallis. 30 1 



T. Evonyniaria (W. V.), has pale ochre-yellow fore-wings, finely speckled with black, and 

 darker on the hind margin ; the fore-wings are marked with black costal spots, and the 

 second line is represented by a row of black dots placed on a pale line ; on the hind- 

 wings is a curved blackish line. Expands from ij to \\ inches. Local in various parts 

 of Germany and Hungary in July and August. The larva is slate-colour, transversely 

 mottled with brown, with black spots on the back, and yellow subdorsal and lateral stripes 

 spotted with red. It feeds on spindle-tree in May. The moth and larva are figured at 

 PI. 49, Fig. I, «, b. 



GENUS VII.— PERICALLIA (STEPH.). 



Body rather stout ; fore-wings slightly and regularly rounded from the inner margin 

 to below the tip ; hind-wings truncated from the anal angle to the middle ; antennae 

 pectinated, with shorter teeth in the female. The larva is thick, with short double points 

 on the 6th and 7th segments, and with two long fleshy projections, which are curved 

 backwards, on the 9th segment. It undergoes its transformations in a loose cocoon, which is 

 suspended to a twig. The only species, *P. Syriugaria (Linn.), has olive-grey fore-wings, 

 varied with pale violet-white, the fore-wings shaded with rusty-yellow before the hind margin, 

 and with large whitish spots on the costa, from which the reddish-white transverse lines arise ; 

 the second is narrowly black above ; the narrow and very oblique central shade is continued 

 on the hind-wings. Expands from ij to 1% inches. Occurs throughout Northern and Central 

 Europe and Northern Asia in May, July, and August. The larva is varied with brown and 

 yellow, and feeds on privet, lilac, and bird-cherry from April to June and in August and 

 September. The moth and larva are figured at PI. 49, Fig. 2, a, b. 



GENUS VIII. — HIMERA (DUT.). 



Rather stout ; fore-wings with the hind margin oblique, and a little projecting above the 

 middle ; hind-wings obtusely rounded, and with the costa considerably longer than the inner 

 margin; antennae of the male with long pectinations ; thorax very downy. The larva has two 

 points on the 12th segment, and undergoes its transformations in the ground. The only 

 species, * H. Pciinaria (Linn.), has reddish-grey wings, with brown central dots, the fore- 

 wings with two nearly straight reddish-brown transverse lines, the second rather oblique, and 

 a blackish spot before the tips ; the hind-wings with a slender dark central line. Expands 

 from if to 2 inches. It is found in the greater part of Europe and Northern and Western 

 Asia from September to November. The larva is of a bark-like grey, with red or yellow 

 spots on the sides. It feeds on oak, birch, willow, fruit-trees, &c., in May and June. The 

 transformations are figured at PI. 43, Fig. 4, a—c. 



GENUS IX. — CROCALLIS (TR.). 



Body thick, rather stout, thorax downy, wings strong ; fore-wings with the hind margin 

 evenly and gradually curved outwards, yellow, with the central area dark, broader on the 

 costa, and with a small blackish spot in the middle; and bounded by two darker transverse 

 lines, edged with paler ; hind-wings rounded, a little longer on the costa, and paler than the 

 fore-wings ; antenna of the male pectinated. Tlie larvae are rather slender, with a flat 

 bifid head and two rows of pointed warts, which are largest on the 12th segment ; they 

 undergo their transformations in a slight cocoon.
