PHYTOMETRA. By W. Warren. 



variabilis. P. variabilis Pill. (= illustris F., cuprea Esp.) (65 c, d). Forewing shining olive grey green, finely 



speckled with darker; basal area paler; inner line broad, double, the inner arm pinkish, the outer whitish, 

 the centre greenish grey, generally indistinct above middle; outer line sinuous, the inner arm pinkish white, 

 the outer broadly pink, the middle green; subterminal line single, white and crenulate; terminal line white; 

 orbicular stigma narrow, elongate, oblique, olive green outlined with whitish; reniform large, indistinct, with 

 pale outline, separated from orbicular by a deep olive green shade, and followed by a diffuse pinkish shade; 

 a rounded triangular mark on vein 2, olive greenish edged with whitish; the median shade and edges of median 

 mongolia. area along the lines deep green; hindwing greenish fuscous with a paler outer band; the form mongolica Stgr. 

 decolor, from Amurland, is smaller and paler, without any pink tinge; a similar form, but not smaller, — ab. decolor 

 sergia. ab. nov. (65 d) occurs in Switzerland and other European localities; the form sergia Oberth. (65 d), on the 

 other hand, has the pink areas amplified, the whole basal area and a broad band beyond middle being bright 

 pink. Larva bluish green; dorsal and subdorsal lines blackish green, the lateral stripe broadly yellow, con- 

 taining the black spiracles; tubercles large and black; venter grey green; forelegs and head black; feeding on 

 Aconitum lycoctonum and Thalictrum aquilegifolium. Occurs on the Alps and Pyrenees, on the mountains of 

 S. Germany, Austria, Transsylvania, the Bukowina, and Wallachia, in Russia at Kasan, in the Ural Mts., and 

 on the shores of lake Ladoga and near St. Petersburg; also in Armenia; it is reported to have been taken 

 many years ago on Salisbury Plain in England, and a single specimen was recorded in later years from Ireland. 



generosa. P. generosa Stgr. Forewing light reddish brown, somewhat like the ground colour of PL cheiranthi; 



with two broad olive fasciae, one near base, the other beyond middle, this latter edged by a golden fascia; 

 a double olive line before the orbicular stigma, attached to a subcellular mark below; reniform obscured by 

 the upper part of the dark outer band; hindwing dark fuscous, the basal half yellowish tinged; comes nearest 

 to renardi Ev. Described from a single somewhat damaged specimen from Haradjan near Zeitun (Taurus). 



comma. P. consona F. (65 d). Forewing pale olive grey, darker in outer half of median area and towards 



anal angle; the inner half of median area suffused with chocolate brown; a quadrate blotch between sub- 

 terminal and terminal lines above vein 3 deep chocolate; a blotch at anal angle before subterminal line 

 shining ferruginous brown; lines ochreous suffused with pink, double; the inner angled on subcostal vein, 

 and toothed outwards on median vein and vein 1; the outer sinuous; subterminal line single, sinuous; veins 

 towards termen pale; orbicular stigma oblique, white, pointed at lower end; reniform very narrow, of the 

 ground colour, the lower end darker; at base of vein 2 a silver loop with deep brown centre; hindwing olive 

 ochreous with darker median line and terminal border, the latter traversed by a pale subterminal line. Larva 

 bluish green, with inconspicuous paler dorsal and spiracular stripes; tubercles finely black, ringed with white, 

 with fine white hairs; head green with deep black marks; feeding on Lycopsis and Pulmonaria. Restricted 

 to S.E. Europe, Saxony, Lower Austria, Hungary, Bulgaria, and S.E. Russia; also in Armenia, Pontus, and Taurus. 



renardi P. renardi Ev. (65 d). Forewing pale olive green strongly flushed with pink; the median area wider 



than in the three preceding species, darker olive green, the space in cell between the stigmata, a faint median 

 shade, and the edges along the lines being olive brown; lines pale, double, with a greenish centre; the inner 

 angled acutely on 'subcostal and finely toothed on the median vein and vein 1 ; the outer flushed with pink ; 

 submarginal line pale, preceded by a greenish shade and a chestnut brown patch on inner margin; a redbrown 

 patch at apex and on termen below middle; terminal line whitish; orbicular stigma oblique, flattened, olive 

 green with white outline; reniform dark grey with pale outline; the loop on vein 2 olive green with silvery 

 outline; hindwing greenish fuscous, with darker median and terminal border. E. Siberia. 



siderifera. P. siderifera Ev. (= beckeri Stgr.) (65 d). Forewing paler than consona F., the grey tinge yellower, 



the dark shading chestnut red; the lines broader, more conspicuous; the space between outer and terminal 

 lines dark brownish olive to costa and there widened; orbicular stigma whitish, shorter, the lower end not 

 pointed; reniform distinct, dark, with pale outline; the cell between them chestnut brown; the loop on vein 2 

 chestnut brown, edged with whitish, not silvery, and somewhat larger; the subquadrate terminal spot produced 

 as a brown blotch across the pale fringe; hindwing cream colour, tinged with pale olive, darker along terminal 

 italica. border. Occurs at Sarepta, S. Russia, in Pontus, and the Ala Tau Mts.; the form italica Stgr. (= calberlae 

 Stindfs.) (65 e), from Gran Sasso, Central Italy and S.E. Taurus, has the scaling rougher and the pale lines 

 more blurred; the ground colour pale olive greenish; the orbicular with slightly darker centre, the reniform 

 filled up with dark brown, the upper half elongate; the mark on vein 2 tongue-shaped, pale edged, with dark 

 brown centre; the hindwing somewhat darker. Larva blue green; the segmental incisions yellowish; the lines 

 whitish but inconspicuous; head reddish marbled with brown; feeding in May on Rindera tetraspis, when 

 young in the spun-together buds. Of the form italica the larva is deep blue green, with six white lines, 

 broader and more conspicuous; the head black, with brown markings; the front feet shining black; the hind 

 feed whitish green with a black ring above; feeding until July on Cynoglossum magellense, in a tube formed
