Austria, Piedmont, etc. — faticium Fame ( = frigidata Vorhr. u. MuU.-JRutz), from Valais, is smaller and rather faueium. 

 darker, the postmedian luae more dentate, the white bands more slender. Perhaps a separate species. — gedren- gcdremis. 

 sis Rondou is still darker, in certain lights with more of a leaden or bluish tinge, the pale markings not very 

 sharp, at least above. Pyrenees, at 2800 — ^3000 m. elevation, flying in late July and August. Only a slight 

 modification of faucimn. 



P. alpinata Scop. (= horridaria Scliiff., carbonata Schr.) (23 c). The most obscurely marked species alpinata. 

 of the genus, the lines and discal dot above faintly indicated, with very slight pale shading distally to the post- 

 median, the underside uniform blackish. Egg long oval, glossy, with hexagonal reticulation; yellow, soon be- 

 coming brown, or according to H. Fischer covered with blood-red spots. Larva undescribed. Pyrenees, Alps, 

 Carpathians, etc., June — -July. A variety said to occur in the Sajan mountains. 



P. noricana Wagner (23 c). Rather larger, less brownish tmged, the lines slightly better expressed, voricano. 

 more dentate, the underside with the distal areaslightly paler than the rest, moreasiircoracwa. — Egg long oval, 

 yellow-green, becoming bronzy brown. Larva similar to that of coracina, in its earliest stages much more 

 brightly coloured; greyish yellow with dark dorsal line, thick black oblique subdorsal streaks and bluish white 

 lateral stripe. Local in the Alps of Lower Austria, Styria and the TjTol, flying in July. 



P. spitzi EM. resembles on the upperside very dark, very sharply marked coracina but with a yellow- spUsi. 

 brown costal spot distally to the postmedian line of the forewing; under surface, on the contrary, confusingly 

 like that of alticolaria. Carniola: Triglav, at an elevation of 2400 m., taken at the end of July among coracina: 

 Carinthia: Karawanken. Possibly a form of coracina. 



P. coracina Esp. ( = chaonaria Frr., trepidata Dup. in err.) (23 c). Somewhat variable m colour but coracina. 

 always smooth-scaled, strongly glossy, with a silvery admixture and without the greenish tinge of the follo- 

 wing species; lines similarly dentate. Underside with strong cell-spots and curved postmedian line, the distal 

 area more or less markedly paler. $ lighter than ^. — ab. wahlbergi Lampa (= argentea 82^. Schneid., argen- wahlbergi. 

 tacea Hirschke) has the ground-colour, especially of the forewing, predominantly silver-white, with only very 

 slight dark dusting, the cell-spot and 2 lines standmg out very sharply, usually also some spots proximally 

 to the subterminal. Commonest in the $. Egg very similar to that of noricana. Larva light brown, similarly 

 marked to that of noricana. Moth in July, Scotland, Scandinavia, the Pyrenees, Alps, Carpathians, etc. 



P. canaliculata Hochenw. (= trepidaria Hhn.) (23 c). Closely similar to the preceding but less strongly cawaiicutafej. 

 glossy, on account of a strong, fine irroration, ground-colour with a distinct greenish tone and admixture of 

 rust-yellow scales. $ often less narrow-winged than in coracina. Rather variable, dark specimens more preva- 

 lent than the paler, more silvery-mixed ones. — Egg relatively large, oval, smooth. Larva violet-brown, finely 

 shagreened with white, sides blackish grey, dorsal line very indistinct except on thorax, segment-incisions 

 with pairs of anteriorly converging dashes on a yellow ground. Pupa smooth, glossy yellow-bro^A'n, anal end 

 in rj finely pointed, darker. Moth in July. Pyrenees, Alps, Carpathians, Bosnia and Herzegovina. 



P. bentelii Rdtzer is a little-known species, related to canaliculata. (J considerably larger, dark slate- hentelii. 

 grey, almost blackish, sometimes without the green irroration of canaliculata ; postmedian line of forewing almost 

 parallel with distal margin, meeting the line of the hindwmg; cell-spot of forewing nearer the postmedian line; 

 underside with very distinct, dark median area, its distal edge very strongly curved at costa. $ considerably 

 more sharply marked, especially on the underside. Local in Southern Switzerland, July — August. 



P. altissimaria Oi. is only known to me from the figure and description. Blackish brown with altissimaria. 

 scattered yellowish scales, discal spots present, the lines sinuous, the pale subterminal line luuulate, on the 

 hindwing with a band before the middle quite different from that of any of the other species. The underside 

 somewhat recalls that of gnophosaria, which I have referred to Gnoplios, but is darker, with uniiiteiTuptea 

 dark band proximally to the subterminal line of the hindwing, etc. From the high mountains of E. Tibet, with- 

 out more exact locality. 



P. quadrifaria Sulz. \= alpinata Schiff. nee Scop., equestrata Bkh.) (23 e) is distinguished at once by quadrifaria. 

 the yellow band on each wing, above and beneath. The name-type is rather small, brownish, the bands on the 

 whole broad. — ab. stenotaetiia Schivingenschuss has the bands greatly narrowed. Glockner. — pyrenaea Oh., stenotaenia. 

 the Pyrenean race, is on an average larger, blacker, the bands on an average slightly narrow, though less so 

 than in stenotaenia. — An aberration (?) with the yellow bands much dusted with dark scales has been mentio- 

 ned as a possible hybrid with alpinata (MtJLLEU-RijTz). — Larva brownish, with dark dorsal line, oblique sub- 

 dorsal streaks and yellowish lateral area. On low plants. Moth in June and July, Alps and Carpathians, etc.
