Apex of the forewing rectangular, margin of the liindwing slightly undulate. Aljove with large, slightly 

 glossy, yellowish or bluish white spot on the hhidwing. Beneath almost without markings, red-brown. Only 

 one s])ecies, }iublished as Oxeoschistus. 



Ch. opalinus Htgr. (5S d). The large silver-grey spot of the hindwing with variously coloured reflections, (iiialhius. 

 According to the angle of light it has a golden yellow or a light blue sheen. The under surface is entirely red- 

 brown with the margin but little darker. Hindwing with dark brown transverse lines, a yellow median dot 

 and a submarginal row of yellow dots. Venezuela. — spoliatus Sli/r. (5S d) is a form of opdlinun with the ■•<i>oH'(tus. 

 yellow dots on the underside of the hindwing entirely absent and the spot on the upperside less white. Like- 

 wise from Venezuela.

After the sj)ecies iif the i)receding genera Jl //(juiifi. Pnjho.scis, D ior istti luid C/ichi/ds, which IJu'i'LER had 

 united with Oxeoschistus, have been removed, this genus only contains c[uite similar species, which agree in 

 the following points: Palpus thinly haired, its terminal joint pointed and projecting for about the length 

 of the head. Apex of the forewing rounded and not distally produced. Distal margin of the hindwing more 

 or less strongly undulate. Most of the species have on the upperside a broad brick-coloured red-yellow sub- 

 marginal band which bears a row of black spots. They occiu' in the high mountains from Ckiatemala to Bolivia,. 



0. pronax Heir. (58 d). On the upperside the band is curved basewards at the costal margin of the promix. 

 forewing, by which the species may be known. Beneath the forewing is as above, l)ut the band whitish at the 

 costal margin, the hindwing red-brown with 2 rows of yellowish white spots before the margin, which are 

 bisected by the lilack veins. Between them some very small eye-spots. Peru and Bolivia. 



0. duplex Gocb/i. (58(1). The band is distally sharply dentate on the hindwing and at the distal dnjilcx. 

 margin there is a row of red-yellow crescents. The black-brown spots on the band are very large. On thi' 

 voider surface the a])ex of the forewing is ferruginous, the band anteriorly white. Hindwing red-brown, the 

 band bordered with white at both sides, a white line is placed in the basal area and the black spots have 

 white pupils. Bolivia, Peru. , 



0. simplex l>th\ (58 e). The band is anteriorly narrow and ])ostcriorly broad and at the inner margin aiiiip/i-.r. 

 of the hindwing extends to the distal margin. The dark sjJots are scarcely half as large as in duplex. 

 The figure of the under siu'face (pi. 58 e) represents a $. In the ,^ the white median stripe of the hindwing 

 is only half as broad. — According to Fassl the egg is the same size as that of Snti/nis briseis, is spherical 

 and has a mother-of-pearl gloss on the surface. The species is distributed in Colombia. F.vssl fovuul it already 

 at 1200 m., but also at altitudes of 2500 m. Acc<.>rding to Godman it also occurs in Ecuador. 



0. puerta Wesfir. (58 d) differs from simplex in that the red-_\cllo\\ band decreases less in breadth imirln. 

 anteriorly, but on the hindwing does not extend to the distal margin. On the other hand the brown distal 

 horder reaches the anal angle. The brown spots vary in number and size. Hewitson gives the number of 

 spots on the forewing as 4, on the hindwing as 7, in the example figured only a few are present. Beneath 

 the brown sj)ots on the forewing are very small, the hindwing similar to that of simplex. Colombia, ^'ene- 

 zuela, Costa Rica. submaculatus Bflr. (58 e) is a form of /)«fr/« in which the red-yellow band is especially vnbiiiaciila- 

 broad on the hindwing and as in simplex extends to the anal angle, but on the forewing becomes very ' 

 narrow and is anteriorly broken up into small spots. Instead of the brown spots there are on the liindwing 

 only a few dots at the anal angle, on the forewing they are entirely absent. Beneath the proximal part of the 

 forewing is very dark. From Costa Rica. --■ pervius Thienie is a similar form to submac tela fits, but considerably p'-n-iK.-i. 

 larger, with the band on the forewing broader and not broken up into sjtots. Fi'om the province of C'auca 

 in Colombia. 



0. isolda Thietne may be recognized by the dark mahogany-red band, which is the same sha])e as in inulila. 

 puerta. thus not touching the distal margin of the hindwing. The spots placed on this band are very small 

 or absent, especially on the forewing. The under surface is similar to that of puerta. but the markings are 

 duller, the ocelli smaller and not bordered with yellow. In the $ the colouring of the upper surface is somewhat 

 lighter. Ecuador (Mirador) (Haensch).
