Ortholitha. 363 



tip divided by a black dash ; the central area darker, broadly olive-brown on the sides, 

 and bordered by two white lines. In the middle it projects strongly and acutely outwards. 

 Hind-wings grey, with a strongly angulated light line beyond the middle. Size of Palumbaria. 

 Inhabits Central Europe from June to August, but not very common. The larva is ashy- 

 grey, with dark longitudinal lines, and is spotted with blackish on the sides. It feeds on 

 broom till June. 



*S. O. Ccrvinata (W. V.). — Fore-wings fawn-colour, lighter at the beginning of the marginal 

 area, with the tip divided by a slight black dash ; subterminal line whitish, and regularly 

 zigzag ; the base and central area are darker on the sides, and bordered by fine white 

 lines, and the central area is rather broader towards the costa ; hind-wings reddish-grey, with a 

 dark curved central line, and the hind margin fawn-colour. Expands from li to if inches. 

 Inhabits Central Europe and Western Asia from July to October. The larva is green, 

 with fine hairs ; pale grey on the under surface and in the incisions. It feeds on mallow 

 in June and July. 



6. O. Peribolata (Hiibn.). — Wings entire, fore-wings with the tip pointed ; bluish-grey, dusted 

 with brown, and traversed by a large central band of a darker brown, and bounded inside 

 by several lines strongly shaded with dark brown ; the inner line is nearly straight, and the 

 second line is expanded in the middle into a more or less prominent curve ; between the lines 

 is a small dot. There are several other brown lines parallel to the two central lines on 

 both the basal and marginal areas. The tip is divided by an oblique brown dash ; hind- 

 wings grey, traversed by two paler lines, of which one is angulated in the middle. Fringes 

 concolorous, preceded by a white line. Expands about \\ inches. Inhabits South France 

 and Spain in August and September. The larva is yellowish, shading into greenish, and is 

 marked with square black spots on segments 5 and 10, and with indistinct brown and 

 whitish lines on the back. 



7. 0. Ca'/inaria (Grasl.). — Very like Biptindaria ; the basal area flesh-colour, traversed by 

 grey lines, angulated towards the costa ; central band broad, greyish-brown, darker and almost 

 black in the middle of the wings, and paler and slightly sufTused with flesh-colour towards 

 the costa. There are two small black dots in a light space on the band as in Bipunctaria, 

 and it is also traversed by four rather waved black lines, rounded outside in the middle, and 

 most distinct towards the costa and inner margin. The second line is black, sharply defined 

 and waved, forms a prominent tooth in the middle, and is followed by a fulvous band which 

 follows its outline exactly, and is bordered by a black line and divided by a grey one. The 

 marginal area is grey, traversed by the waved whitish subterminal line, which is united to 

 an oblique subapical dash. Fringes ashy-grey, spotted with brownish-grey, and preceded by a 

 black festooned line. Hind-wings uniform reddish-grey, darker towards the hind margin, and 

 with three indistinct pale transverse lines. It is found in the Pyrenees in July; and the 

 Spanish variety Jugicola (Stand.) is larger and paler, (j^. Proxiiiiaria, Ramb., from Corsica, has 

 pale grey fore-wings, with a black central dot and transverse lines, and a black central waved 

 band strongly projecting outwards. The larva is darker than that of Peribolata, and the 

 markings are lighter. O. Obvallaria, Mab., found in Corsica in July and August, resembles 

 O. Mcrniata ; it is dark grey, with the central area and hind margin varied with whitish, the former 

 with two black dots in the middle. The line separating the basal and central areas is black, 

 bidentate, and bordered within with yellowish, and the black elbowed line is bordered outside 

 with yellowish. The latter projects strongly outwards, and is bidentate, forming a shallow W. 

 The apical dash and subterminal line are indistinct ; hind-wings dark grey.
