tlie hyaline spot more elongate and outside deeper concave. Hindwing darker brownish-grey, beneath the distal 
transverse line is finely crenulate. Guatemala; Costa Rica; a somewhat smaller and beneath greyer and more 
monotonous specimen from Colombia (Muzo). 
0. guanduna sp. n. (141 i) is likewise near microps, but much more variegatedly spotted and easily 
discernible by whitish scales being accumulated at the cross-vein and by a transverse row of white subterminal 
dots arranged outside on the black vein-dots; the two median lines are much closer together, the posterior one 
is less curved; the first antemedian line is much more notched than in the preceding species; marginal area 
more profusely strewn with white. On the quite pale yellowish sand-coloured hindwing only the inner-marginal 
portion and a marginal band are broadly darkened brownish-grey, 2 feeble transverse lines are not angled below 
the costal magrin as in the preceding species, but slightly bent. Beneath the forewing is almost yellowish-white, 
the hindwing densely and coarsely strewn with dark brownish-grey, the veins whitish, the transverse lines much 
stronger than above, obtusely angular on 5, the distal one outside bordered with white. Type: 1 from Guandu ( ?) 
(Espiritu Santo) in the Berlin Museum. 
0. mutusca Schs. (141 i) is above lighter grey than microps, only very scantily strewn with black, at 
the apex darkened, with the usual 2 transverse bands, the interior edge of the basal one and the exterior edge 
of the distal one marked by some black vein-dots, behind the latter another notched subterminal line; hyaline 
spot small, round, yellowish, below it mostly a tiny black spot. Hindwing brownish with 2 transverse lines, 
the interior line faded and more reddish than the exterior, more distinct, blacker line. Beneath discernible 
by the very strongly notched exterior transverse line of the hindwing. Rio de Janeiro. 
0. castrona Schs. (141 i) is smaller, light grey, scantily strewn with black, in the costal-marginal portion 
also with some red-brown scales; both the antemedian and postmedian transverse lines are very close together 
so that they almost look like double lines without any brownish filling between, only at the costal margin their 
beginnings are somewhat broader red-brown, the two postmedian lines at the costal margin like 2 oblique 
costal-marginal streaks, behind them a small red-brown triangular spot representing the beginning of the 
otherwise quite extinct submarginal line; hyaline spot very small. Hindwing light brownish, 2 transverse lines 
hardly noticeable. Beneath very pale brownish, the hindwing somewhat more coarsely strewn with black, both 
wings with 2 extinct transverse lines, the interior one on the hindwing broader and more red-brown, the exterior 
one strongly notched. Castro (Parana). 
0. castra Jones, described from a $, was not before me. Fore wing ochreous, strewn with blackish- 
brown. especially costally and in the marginal area; a faded dark blackish-brown antemedian line is very 
strongly undulate, the similar postmedian line less distinct, behind it a dentate subterminal line; margin 
ochreous, fringe blackish-brown; at the cell-end a large round blackish-brown spot, the hyaline spot between 
5 and 6 small. Hindwing glossy ochreous with 2 postmedian lines, the interior one red-browm, the exterior 
one more distinct and blackish brown. Beneath on the ochreous forewing with a brown cellular shadow being 
darkened on the cross-vein, and an undulate brown postmedian line; hindwing marked as above, but more 
intensely strewn dark and with a discal dot. Expanse of wings: 35 mm. Castro Parana. 
0. brama Schs. (141 i) is above separated from the preceding species by the red-brown colour and its 
larger size; forewing strewn with a darker purple brown, especially in the basal third, the broad antemedian 
band still darker; at the cross-vein there is a small black light-edged spot; postmedian line of the usual shape, 
behind it at the costal and inner margins one small dark spot each ; the undulate-dentate subterminal line on 
the inward dents intensified by black vein-dots; the subapical hyaline spot is yellowish, outside indented, 
below it often with a small black spot. Hindwing dark red-brown with 2 feeble transverse lines the distal one 
of which is crenulate beneath. Colombia; also from Sa. Catharina. 
0. oriunda Schs. (141 i). Forewing dark ochreous, with brown transverse bands, the interior one basally 
distinctly bordered with black, outside faded, the exterior one on the contrary outside distinctly notched, inside 
faded; between the bands a black discal dot; below the small hyaline spot a black spot in which there is often 
another small hyaline spot. Hindwing coloured like forewing, with 2 transverse lines. Maroni R., French Guiana. 
0. ibar Schs. (141 i) is quite different; body light sand-coloured, head and thorax suffused with olive- 
grey, abdomen with lighter rings. Forewdng light sand-coloured, dusted with light olive-grey, with double 
sandy brown antemedian and postmedian lines, the latter finely bordered wdth a darker colour, the outer line 
on 5 distally angular; the light subterminal line runs straight from the costal margin before the apex to the 
anal angle, befoi’e it at the costal margin a dark brown triangular spot, and behind it above vein 5 a black 
dot; apex pointed, almost falcate, the margin slightly dentate. Hindwing with a cinnamon-reddish tint wdth a 
slightly darker median band, bordered by a dark median and a light postmedian line. Beneath the forewdng 
is without the antemedian line; hindwing bright, median band brown, outside distinctly bordered wdth white. 
From Cordoba (Argentina), described according to a $. 
6. Genus: Thyrioclostera gen. n. 
The only representative, originally described as a Callopistria, by Druce as Carthara, would match 
very well Olceclostera by the shape of the wings, but the neuration is different. According to Schaus w r ho
