EREBIA. By G. Weyimer. 237 



striated %\-ith dark b^o^vn, with an oblique row of white dots. Very common in the mountains of Chile. The 

 figure is from Feldee's tj'pe of valdiviae. 



E. coctei Guer. (= tragicus Reed) (51 d). Above brown, somewhat dusted with rust-red and with some cociei. 

 rust-red spots at the anal angle of the liindwing. The $ is rust-reddish to beyond the middle and has before 

 the apex an eye-spot ^vith double piipil. On the under surface the forewing in both sexes is red-yellow with 

 a similar eye-spot, the distal margin and the huidwing lighter brown, the latter with a lighter band beyond 

 the middle. According to Elwes locally common in the Chilian mountains. 



E. tristis Giier. Somewhat larger than coctei. According to the figure in ,, Voyage Coquille" above uni- tnsiis. 

 colorous dark yellow-bro^vn ^vith the veins lighter and a small, round, pale yellow spot at the end of the cell 

 on the fore'tt'uig. On the under siu'face, wliich is not figured, according to Gxjerin's description there is a yel- 

 lowish wliite line on the hindwing, anteriorly expanding into a large spot of the same colour. According to 

 Elwes the species is locally common in Chile. — pales Phil. (51 d). Perhaps a form of the preceding. Above pales. 

 g^ey-bro^vn with 2 small red-yellow spots at the margin of the hindwing. Forewing beneath red-yellow, costal 

 and inner marguis narrowly yellow-grey, distal margin broadly yellow-grey, a large eye-spot with double 

 pupil before the apex. Hindwing beneath yellow-grey with the margin lighter. Chile (Valdivia). 



E. flora PJuI. (= Pedal, oaxes Btlr., Stibomorpha tristis Btlr.) (51 d). Above brown with 1 or 2 red- flora. 

 brown spots, which, however, may also be absent. Fringes chequered with yellow and brown. Beneath: fore- 

 wing spotted -w-ith red-yellow and brown, its costal margin marbled with black and white. Hindwing marbled 

 with dark brown, with a yellow spot in the middle, an undulate white transverse band and a white spot at the 

 costal margin. Province of Valdivia (Chile). Philippi desci'ibed the species as a Satyrus, Butler first as Pe- 

 daJiodes, then as Stibomorpha. On account of the basally inflated median I place it here. 



E. nycteropus Beed (51 d). Above brown, in the cJ with dark brown scent-scale patch, in the $ with nyctcropus. 

 dark red-yellow median spot on the forewing. On the hindwing some red-yellow submarginal spots. Forewing 

 beneath red-yellow, distal margin broadly, costal margin narrowly grey-brown, a round apical ocellus with 2 

 white pupils m. ochre-yellow ring. Hindwing grey-brown with a dentate white median stripe. In the middle 

 of the lighter margmal area 2 light yellow spots. Differs also from flora Phil., to which it bears some resem- 

 blance, in not having either the fore- or hindwing dentate and in the more produced apex of the forewing. Rare 

 and apparently confined to the coast-region of Central Chile. 



E. poliozona Fldr. (51 d). Above unicolorous brown. Beneath brownish red-yellow with the margins poliozona. 

 of the forewing grej'-brown, a blind apical ocellus, hindwing with a light lilac submarginal band. On this is 

 placed in cellule 2 and m cellule 5 a black dot. Chile. 



E. gyrtone Berg. Above browTi, the (J with a double eye-spot before the apex and without eye-spots gyrfone. 

 on the hindfting. In the 2 in addition a 2nd small eye-spot in cellule 2 of the forewing and 5 on the hindwing. 

 Beneath yellowish grey, with a lighter band before the distal margin, partly white on the hindwing, on which 

 are placed the black, white-pupilled and yellow-ringed ocelli, in the c? 2 on the forewing and 4 on the hindwing, 

 in the 2 3 on the forewing and 5 on the hindwing. The first eye-spot on the forewing is larger and bi-pupil- 

 led. The band is proximally and distally bordered by a dark line. 39 — 45 mm. Found in the south of the 

 province of Buenos Aires (Sierra Tandil). 



E. imbrialis Weeks. Above bronze-brown. On the forewing a dentate dark brown line runs from the imbrialis. 

 apex to the submedian and from there back, touching the discocellular, to the middle of the costal margin. 

 In the triangle thus formed is placed before the apex a black double eye-spot with 2 silvery pupils and light 

 b^o^vn ring. The hindwing has a fine dark brown submarginal line and only occasionally a small eye-spot 

 with single pupil at the anal angle. The under surface of the forewing is as above, only much lighter, the eye- 

 spot is larger and has a yellowish white ring. The apex is dusted with grey. The hindwing is grey beneath, 

 strongly dusted with brown, with a broad grey band, proximally bordered with brown, before the distal margin. 

 Sometimes a row of brown spots is present in the middle. Thus the species is apparently very variable. From 

 Bolivia, Alezmii district. 



28. Genus: Erebia Dalm. 



Only the costal of the forewing is strongly inflated at the base. Of the subcostal veins 2 usually arise 

 before the end of the cell, sometimes only one. The 4th subcostal vein runs into the apex of the forewing. The 

 antenna has the club distinctly prolonged. The palpus is anteriorly clothed with long, stiff hairs, above with 

 shorter hairs. The distal mai-gin of both wings is rounded. The Erebias are mostly small dark brown butter- 

 flies, scarcely reaching medium size. Their range of distribution embraces the whole Palearctic and Nearctic 

 Region. They are mostly mountain butterflies, inhabiting the alpine regions of Europe, Asia and America. 

 Only a few .species descend to the hills. In comparison with the Palearctic Region the number of the American 

 species is small. For the habits and life-history of Erehia cf. further vol. I, p. 94 and 95.
