EUPITIIECIA. . 405 



in July. The larva is green, with a yellowish-white stripe on the back. It feeds on a species 

 of Polygomun in June. 



75. E. Distiiictariii (Herr.-Schiiff.), Extravcrsaria (Herr.-Schiiff.). — Fore-wings bluish-grey, the 

 double stripes not much curved, the transverse lines slender and sharply defined ; the central 

 spot resembling a streak. Expands three-quarters of an inch. Very local in France and Ger- 

 many from June to August. The larva is green, with blood-red transverse streaks, or large 

 blood-red spots. It feeds on the flowers of Pcncedanuin oreoselinnm in August and September. 



•jQ. E. Libanotidata (Guen.). — Probably a variety of the last. The fore-wings are broader 

 and rather pointed ; brownish ashy-grey ; the double stripes and subterminal line not paler 

 than the ground-colour, the former only indicated by dark transverse lines expanded into 

 spots on the costa, of which the first line of the last stripe is blackish and more distinct ; 

 the last stripe is strongly arched, and broader on the costa ; the subterminal line is slightly 

 zigzag, and the central spot consists of a thick black and uniformly broad streak, broader 

 than in the other species; hind-wings unicolorous, and indistinctly waved with darker; the 

 under side with rather sharply-defined markings. It occurs at Jena, and the larva feeds on 

 A tliainantha lihanotis. 



yj. E. Heydenaria (Stand.). — Rather larger than Virgaureata ; the black central spot well 

 marked ; the dark costal spots are better defined than in Virgaureata, and arranged as in 

 Pimpincllata, and distinct blackish lines run from the spots at the base and beyond the central 

 spot to the inner margin, and, in the female, across the intermediate space also. This gives it 

 some resemblance to Disiinctaria and Libanotidata, but It is not nearly so distinctly marked. 

 The light subterminal line is much suffused. Hind-wings with a very indistinct central spot or 

 streak, and scarcely waved. Under side with two complete transverse lines beyond the central 

 dot, which only extend distinctly to the fore-wings in the male ; the costal spots are also 

 tolerably distinct below. Inhabits Switzerland. [E. Undosata, Dietze, is a brownish-green 

 species from Livonia; the male resembles Virgaureata or Al/enaria, and the female resembles 

 Heydenaria or Castigata, but it may be distinguished from any other species by the central 

 area of the fore-wings being bordered on each side by two parallel dark lines.) 



yZ. E. Scxtiata (Mill.). — Fore-wings long and broad, dull grey, traversed by three oblique 

 and continuous lines, which are not festooned. A fourth line traverses the central spot, is 

 angulated above, and extends to the inner margin. All these lines are well marked on the 

 costa. The subterminal line is light, waved, and continuous, and the central spot is rather 

 large, square, and black. Hind-wings grey, with a broad continuous band hardly paler than 

 the ground-colour. Fringes chequered with grey, and preceded by a row of small black marks, 

 separated by pale dots. Expands about three-quarters of an inch. Inhabits South France and 

 Spain in April. The larva is greenish, or dark purple, with a dark red stripe on the back. It 

 feeds on the seeds of the thyme, and is full-grown in May. 



*79. E. Indigata (Hiibn.). — Fore-wings narrow and pointed, pale reddish-grey, with a large 

 black central spot, and suffused grey transverse stripes, expanded into darker spots on the 

 costa ; the double stripes very indistinct, and not lighter than the ground-colour, the last 

 curved, and the subterminal line also indistinct ; hind-wings paler, and nearly unicolorous. 

 Expands about three-quarters of an inch. Common in most parts of Europe in May, June, 

 and August. The larva is pale greenish-yellow or yellowish-red, with a reddish-brown line on 

 the back, and pale yellow subdorsal and lateral lines. It feeds on fir, juniper, cypress, &c., in 

 July. (£■. Altenaria, Staud., found in Lapland and Norway in July, is allied to Castigata and 

 Trisignaria ; it is grey, with more or less distinct whitish transverse lines, which are acutely
