796 DYSDAEMONIA. By Dr. M. Draudt. 
being Venezuela is due to a mistake. Forewing purple red-brown, dusted with violettish-white, the transverse 
bands not dusted, two each before and behind the long narrow discal streak, then follows a fine bluish-black 
line extending from the last third of the costal margin to the last third of the inner margin, i. e. from here from 
the margin parallel to about midway between veins 3 and 4 and as far as this place double and filled with 
bluish-white, then inwards in an obtuse angle and widened and turning brown towards the costal margin; the 
distal portion is still more widened and divergent almost in the original direction. Hindwing in the basal two 
thirds blackish-grey, separated from the red-brown marginal portion by a rectangularly flawed violet whitish 
band. The $ is mostly much brighter brown. In gravis Jordan the bands of the forewing are straighter than 
in South-Brasilians; beneath without a red-brown marginal band on the forewing, the hindwing unicoloured 
brownish greyish-black with a small reddish-brown apical macula. French Guiana. — andensis Rothsch. has 
a more rounded margin of the forewing, a broader marginal area, a straighter double line; the narrower post¬ 
median band touches the cell-end. The upper portion of the white band on the hindwing is much nearer to the 
margin, the black band is twice as broad as in pluto. South-Eastern Peru. 
D. mayi Jord. (= pluto auct. nec Westiv.) (127 c) is a very similar species, mostly somewhat larger and 
darker, more blackish, easily discernible by the black double line reaching the inner margin in the middle or 
even before it; the darker transverse bands are narrower and straight as in gravis. Rio de Janeiro. 
D. orsilochtss ( Bsdv. i. 1.) Maass. (130 A b). According to the kind information by Jordan this name 
was published by Maassen below the figure which was to represent pluto Westw. The figure, however, is not 
pluto but another species which must therefore bear the name placed below it, because this name refers to the 
bad figure being better reproduced by Plotz, the original of which we are able to figure. Ground-colour darker 
than in pluto , the double line straight as far as up to vein 6, then the interior portion vanishes, the exterior 
portion extends widened, shadow-like in the same direction to the costal margin, ending at the inner margin 
almost exactly in the middle as in mayi ; the dark bands enclosing the median area are dark purple brown and 
altogether fill up the lower half of the median area, the innermost line becomes very feeble towards the costal 
margin and bends towards the base below vein 1. Hindwing light sandy grey in the basal half, then follows a 
broad purple brown transverse band separated by sandy brownish colour from the broad violettish-white 
transverse band which is slightly angled, then follows again a purple brown transverse band being very narrow 
at the costal and inner margins; two rusty yellow large spots at the apex and below it. Brazil. 
D. platydesmia Rothsch. (= d’espinayi Bouv.) has the same shape as pluto , the black double line 
terminates at the inner margin at %, being also narrower and finer in the costal-marginal portion, more distinct 
than in the allies and less divergent; the angle of its bend being nearer to the inner margin than in pluto ; instead 
of the distinct 4 transverse bands there are here but two though broader bands, the anterior one touching the 
inner margin almost rectangularly, the discal streak is not so isolated, but unites in front with the ante- 
median band. Hindwing as in pluto, fringe bright rusty red. Antennae more feebly pectinated than in the 
allies. In the nomenclatural form, from Peru and Colombia, the bands of the forewing are very dark chocolate, 
the white band of the hindwing very feeble towards the costa. castanea Rothsch. (127 b) is larger, exten¬ 
sively suffused with chestnut brown, also beneath, the white band of the hindwing broad as far as the costal 
margin. Costa Rica. 
D. nycteris Jord. (127 b) has longer and narrower wings, the forewing is more produced at the apex 
than in all the other species with more indistinct brown bands, the spaces between them are more pale grey 
and darker streaked; discal spot elliptical, black, enclosing a light brown line. Hindwing with a long and 
narrow tail: both wings with a red-brown marginal line inwards bordered by a black line. Under surface pale 
grey, densely covered with purple black transverse striae, suffused with red-brown in and behind the cell. 
Venezuela. 
D. thelia Jord. (= wagneri Bouv.). The male exhibits the more rounded wings of the $$ of the other 
species, similar to pluto- $, considerably smaller, the double line reaches the inner margin at % as in pluto, 
both the lines being widened towards the costal margin, but the exterior line much narrower than in pluto ; 
hindwings with shorter tails. Beni ath unicoloured dingy brownish-grey, without transverse striae. From 
Paraguay and Argentina, also from Rio Grande do Sul. 
D. samba Sells. (134 c) is a smaller species, the margin of the forewing is straighter and more oblique; 
purple brown, dusted with violettish-white, with 2 rather straight transverse lines bordered with white inwards, 
the posterior one meeting on the submedian fold the double line which is filled with white and strongly bends 
towards the base below the costal margin, where it is broadly edged with white on both sides. Hindwing with 
but one quite indistinct darker straight transverse band. British Guiana. 
B. terrena Jord. (= orsilochus South, nec Maass.) is similar to samba, paler, with broader hindwings. 
Both wings beneath with a very distinct black discal dot, the hindwing without the rusty brown apical spot 
which is replaced by a blackish macula. French and British Guiana.
