DIRPHIA. By Dr. M. Draudt. 
described of a brownish-grey ground-colour with a somewhat more prominently dark median band of a variable 
width, at the margins edged by whitish lines which gradually pass into the brown ground towards the averted 
sides; the somewhat irregular subterminal band is widened towards the costa and darker. Hindwing at the base 
feebly red-brown, with a narrow blackish submarginal band bordered lighter on both sides. Abdomen as in 
all the allies black with orange bands, especially in the $ intermixed with very long greyish-white hairs. Panama; 
nora. Colombia; Venezuela; Guiana; Eastern Peru; Trinidad. rsora Drc. (117 A c, d) is the mostly somewhat smaller 
form with a much lighter pinkish-brown ground-colour; especially in the $ the median band is reduced to a 
chestnut-brown costal triangle, sometimes, as in the figured specimen with an inner-marginal spot besides, 
more rarely with a distinct median band which is almost invariably present in the $. The type is from Panama; 
(riangu l um. distri buted as far as Colombia. triangulum Wkr. (117 Ad) denotes specimens of a more violettish-grey ground¬ 
colour with a distinct olive green colouring of the costal-marginal triangle resp. median band; the subterminal 
band also shows a greenish tint; in both sexes the triangular spot may be widened into a median band, in any 
case they are bordered with a lighter lilac whitish colour. Hindwing at the base sometimes very bright rusty 
red. Mexico to Brazil and Bolivia. All the said forms are not distinctly defined, but extremely variable in 
colour as well as the development and size of the costal-marginal triangle or the median band, so that, if there 
are a sufficient number of specimens at hand, one may have all sorts of transitions. Nor is the neuration 
constant (cf. p. 764), but most variable. On superficially examining the forms I found the uncus of the $ to 
be of the same shape in all the three forms. 
dentimacu- D„ dentimaculata Schs. Anterior body dark brown intermixed witli yellowish-white hairs, frons light 
Utta. p rown ■ abdomen orange with black bands. Fore wing light ochreous, with the exception of the marginal area 
thickly strewn with brown, a dark brown postmedian shadow fadedly passes over into the mai’ginal area; in 
the centre of the costal margin a large brown triangular spot bordered at first with black, then with white, 
proximad deeply strangulated and distad with 3 short projections. Hindwing brownish with blackish-brown 
postmedian and subterminal shadows, the space between them being ochreous like the margin, and strewn with 
brown. Under surface light ochreous with feeble greyish-brown postmedian and subterminal shadows. Expanse 
of wings: 80 mm. Brazil. 
hortensia. D. hortensia Schs. (117 B a). Thorax olive with light brown hair, abdomen brownish-red, with black 
bands. Fore wing yellowish reddish-grey, strewn with olive and with irregular fine horizontal striae; an indis¬ 
tinct subterminal shadow, below the costal margin widened into a darker shadow; centre of costal margin 
with a large olive brown, lighter haired triangular spot, bordered with black, enclosing a black discal streak, 
the distal border being feebly undulated. Hindwing at the base and inner margin brown, outside and towards 
the costal margin darker shaded, with a dark discal spot and a blackish-brown postmedian and subterminal 
shadow, marginal area as on fore wing. Sao Paulo (Brazil). 
muscosa. D. muscosa Schs. (117 B a) is apparently more common, very similar to hortensia in the olive greenish 
ground-colour; the costal triangle is chiefly developed into a narrowed band extending to the inner margin and 
being outside and inside strongly dentate; its black border is besides mostly bordered outside with whitish; 
hindwing at the base of a brighter brown, the discal spot and the two anteterminal lines very thick and distinct. 
Abdomen bright rusty red with black bands and intermixed with long light yellowish-grey hairs. Colouring 
and marking most variable, often very dark blackish-green, particularly the are frequently intensely inter¬ 
mixed with white, the median band is often very broad, often narrow, occasionally internipted above the inner 
margin, so that there is a small isolated inner-marginal spot is left, which may also be absent, so that only 
the costal triangle is present. Venezuela to South Brazil, a great many specimens being at hand. 
curitiba. D. curitiba s'p.n. (117 B b) is evidently very closely allied to muscosa , but smaller, the ground-colour 
basally and in the marginal area more lilac-grey, as in triangulum, only the broad median band being olive brown; 
the coarse striation and strewing of the preceding species is entirely absent; the median band is on both sides 
regularly though flatly dentate, scarcely bordered with black, but on both sides bordered with a whitish line; 
the black discal spot indistinct and much less obliquely arranged; the darker subterminal shadowy band is 
very faint and almost rectilinearly defined, whereas in muscosa it recedes far between 4 and 6. Hindwing brown, 
towards the base yellowish ochreous, the 2 anteterminal nebulous bands very feeble, the discal spot being 
absent altogether. According to 2 $$ from Curitiba, type in the Senckenberg Museum, Frankfurt o. M. In the 
co-tyjje the median band is scarcely dentate. 
jorgenseni. D. jorgenseni Schs. The black body is scantily intermixed with yellow hairs; antennae yellow. The 
light ochreous ground of the wings is strewn with brown; forewing at the base narrowly black, the fine black 
transverse lines are feebly denticulate, the antemedian line is excurved at the costal margin, then vertical, 
the posterior line excurved at the costal margin then somewhat incurved; at the cross-vein a small black spot; 
marginal area somewhat lighter, at the apex narrow, between 4 and 6 broad. Hindwing with a short black 
discal line and a blackish-brown postmedian shadow. Expanse of wings: 90 mm. Argentina (La Junta). 
baroma. O. baroma Schs. was not before me. forewing reddish-brown, dusted with blackish as far as the 
subterminal line projecting in roundish bows between the veins of the marginal area; at the cell-end a round 
black, grey-circled dot; base red-brown, bordered by an oblique white line. Hindwing in the basal half reddish, at
