the veins remaining glossy vvliite. Beyond the middle a row of Ki'.iwn spots, l)ef()re tlie distal margin a row 

 of brown crescents. The liabitat is Chile, where the butterfly is loc'ally common in the Cordilleras oF the cen- 

 tral provinces and on the Argentine borders in January and February, but is difficult to catch on account 

 of its rapid flight. Only in the early morning it is more easily caittiued. The altitude at which it occur.s 

 is given as between ."iOOO and 7()()(»ft.

 rather })road brown-black border, 6—.Smm. in Ineadth at the apex, 2 mm. at the anal angle. Fringes Ion"- 

 and luown. Ilindwing entirely brown, towards the base somewhat lighter. Beneath brown, the apex of the 

 forewing and the whole hindwing s])rinkled with grey-white atoms and with white longitudinal lines between 

 the veins, on which are placed on the forewing two black dots and on thi' hindwing a row of 5. Proximallv 

 to these on the hindwing several further rows of small dots. From Bolivia. — To a local form of this species 



1 give the nanu' ailgusta joriit. nov. Instead of the broad brown distal margin of the fore\\ing there is here only (uujiwta. 

 a narrow brown marginal line and before this a second line, only distinct in the anterior half of tlie 

 wing. At the a])ex of the costal margin is placed a narrow brown triangle, its shorter side only occu])ying 



2 mm. of the distal margin. Below this triangle there are 3 brown dots on a silver-white ground, at a dis- 

 tance of about 4 mm. from the distal margin. Fringes brown, spotted witli white at the ajjcx. On the under 

 surface both wings have a sharply pronrincnt white marginal liiie, the veins of the hindwing are likewise 

 white, and the rows of dark dots very distinct. Likewise from Bolivia.

Club of the antenna thin, moderately excised. I'aljius thin, twice as long as the head, upjier disco- 

 cellular of the forewing short. Distal margin rounded, that of the hindwing slightly undulate. This genus 

 was founded by I^eldkr on lepfoiieurode.s and afterwards extended by Elwes.

 submarginal band on the hindwing. On the muler surface the forewing is grey-br(jwn, basal and median areas 

 red-brown, before the a)jex with a round black eye-spot with double white j)upil and yellow ring. The hind- 

 wing is olive-brown to beyond the middle, then follows a dentate w-hitish yellow band ajid in the marginal 

 area a row of 5 eye-spots, those in cellules 2, 5 and 6 black with white pupils and yellow and brown rings, 

 the others, in cellules 3 and 4, white with black ring. At the distal margin is placed a narrow \\'liite stripe, 

 which is divided into spots by the dark veins. The butterfly is rather common in the mountains of Chile 

 at elevations of 3000 to 5000 ft. Flies at the end of January and in February. — plumbeola Bllr. is a iihnnhmJa. 

 local form of leptoneurodes, only differing in the presence of a bi-cvu'ved brown line on the underside of the 

 forewing, bordering the red-brown median area. From Port Famine on the Straits of Magellan. — duseni <S7;/*'. (hi.snii. 

 is a quite similar form to pluinheola, the differences according to Elwes being extremely slight; it was taken 

 on the Rio Aysen in South Chile.

 grey; in the '^ a romid black spot is placed before the apex of the forewing and in its vicinity 4 — (i small red- 

 yellow spots. On the laider surface the forewing is dark red-yellow to beyond the middle, the distal margin 

 broadly grey, the black spot surrounded with ochre-yellow, hindwing grey-brown, marbled with dark brown 

 and Avhite. The butterfly is common in CHiile from November to December and ascends from the coast to 

 elevations of 4000 ft. — nionticolens Bllr. is a form of chiliensis which chiefly differs in having a row of () fHonlicoicii.'i. 

 black, whitish-bordered spots, placed on a broad Ijrownish white sid)nuirginal band on the underside ol the 

 hindwing in cellules lb — 0. There are also here on the distal juargin large dark brown spots between the 

 entirely white veins. The butterfly is to be found on stony grass-lands in the higher mountain regions of Chile 

 from 4500 to (idooft., but is difficult to catch on account of its rapid flight. — williamsianus Btlr. (= Oeneis iciUUnii- 

 antarcticus Mab. [according to Elwes]) is a .small form belonging here, in which the median band on the under- ■''■"'""*■ 

 side of the hindwing is cvu'ved distally. The light band which follows is broader and instead of the eye-spots 

 of monticolens there is here a row cf 5 black dots, some of them indistinct. From Port Famine on the Straits 

 of Magellan (mildrcticiis Mah. was discovered at Santa Cruz, a haven on the east coast of Patagonia at 50"

 is brown, before the distal margin with a broad light ochre-yellow nmcular band, composed on the forewing 

 of 6, on the hindwing of 4 spots. The first 3 spots on the forewing are long and narrow, in the 2nd is placed 

 a black spot, the 4th and 5th are broader and long, the (3th also broad, but short. The 4 spots of the hind-
