768 DIRPHIA. By Dr. M. Drattdt. 
with black, remaining during the day on the food-plant (Eucalyptus, Mimosa etc.), sabina from dark grey 
larvae hiding in the daytime on the trunk of the same food-plants. The problem sabina-simillima must yet 
be carefully investigated. Jones considers sabina to be the species with a male uncus split like a Y, simillima 
that in which the spiny uncus is somewhat stalked patelliform. Bouvier, on examining the species in the Paris 
Museum, found simillima to be the form occurring to the north as far as Mexico, sabina to be the Brazilian 
form, which fact I can substantiate according to about 50 specimens at hand. All the specimens from Mexico, 
Guatemala, Venezuela, and Colombia have an unsplit uncus, thus to be placed to simillima , whilst all the 
Brazilian specimens befoi’e me are sabina. Jones on the contrary, however, found in Brazil the larvae of b o t h 
forms at the same time on the same food-plant. The neural differences in both forms or species stated by 
Boitvier I cannot confirm according to the great number of specimens before me; I have never seen such an 
oblique course of the discocellular as it is sketched by the said author, in all the specimens seen the cross-vein 
stands almost vertical on the upper and lower cell-margins. Moreover, it is very easy to state where the d 
belongs to, since by slightly brushing off the anal hair the very characteiistic uncus is at once visible; as to 
the it seems that all attempts of identification have been in vain. 
D. basina Maass. is similar, but smaller, darker, on the forewing much more mixed with blackish-grey, 
particularly in the marginal area ashy grey. Hindwing slightly hued with salmon-pink. Abdomen orange, 
with narrow black rings. From Venezuela (La Guayra). 
O. binasa Schs. (114 h) is very similar to basina , at once discernible by the abdomen being quite black 
above; forewing somewhat lighter, in the median area pinkish-white, the anterior transverse line irregularly 
notched brown, double, the posterior line deeper black; the light ashy grey subterminal band is traversed by 
orange veins, the narrow marginal area behind the white undulate line is orange brown. Hindwing salmon- 
pink, the postmedian line which touches the black discal spot with a jet-black central line is incurved below 
the costal margin, behind it there is a broad black subterminal band; the pink marginal area between the 
orange veins is densely strewn with black. Argentina (Tucuman); also from Rio de Janeiro. 
D. basinoides Bouv. is allied to sabina - and basina. Body the same, on the rusty red abdomen also with 
orange spatulate hairs. Forewing in the basal costal marginal half as far as the median vein and the postmedian 
line grey, the large yellowish grey dark cellular spot somewhat rectangular, bordered with whitish; transverse 
lines as in sabina, olive grey, bordered with white; subterminal area blackish grey, the darkest proximad; the 
space below the cell olive grey like the marginal area behind the white irregular submarginal line; veins in the 
distal two thirds orange. Hindwing unicoloured yellowish-white at the margin olive grey, before it with a 
blackish subterminal band, traversed by the orange veins; at the cell end only a feeble blackish streak. Ex¬ 
panse of wings: 64 mm. Brazil, described according to a single <$. 
IV. speciosa-group. 
B„ cutteri Schs. Head and mesothorax reddish-yellow with a black spot on the collar, metathorax dark 
pink, abdomen as in the preceding species. Forewing reddish-brown, suffused with pink, with black veins, at 
the cell end a thick antimony yellow spot with a whitish dent along vein 4 distally as far as behind the broad 
blackish straight postmedian line; fringe at the distal and inner margins pink. Hindwing pink, with black 
veins with broad blackish postmedian and subterminal shadows. Ecuador. 
D. upanona sp. n. (116 b) is very similar to cutteri and perhaps a form of it. Head and thorax black, 
collar and patagia with single yellow hairs, abdomen quite black with reddish ochreous anal hair. Forewing 
coffee-brown, with black veins, the discal spot quite yellow, fringe claret-coloured: the blackish postmedian 
shadow is scarcely visible. Hindwing quite sooty black, without markings, with fine black veins which are 
thickened into small triangles before the claret-coloured fringe. Type: 1 <$ from Normandia, Rio Upano, 
Ecuador in the Coll. Bang-Haas. 
D. rad am a Drc. (116 b) is chrome-yellow, in the inner marginal portion of the fore wing dusted with a 
somewhat deeper or brownish colour, with fine black veins, a white, above black-striped Y-spot at the cell end, 
cutting a blackish shadowy line. Hindwing likewise yellow with a blackish postmedian shadow; fringe speckled 
black and white. Abdomen black, with white rings and an ochreous anal tuft. Ecuador. 
D. mola Drc. (116 b). Head and thorax rusty vellow r , wings pink, with yellow veins; forewing in the 
median area and at the inner margin slightly mixed with a rusty yellow colour; cellular spot as in radama, but 
the white discal portion broader and rounder. Hindwing at the inner margin with rusty yellow hair, with a 
small whitish discal spot. W. Colombia, San Antonio; before me from the Aguaca Valiev. 
D. pachona sp. n. (116 b) is similar to mota, larger, forewing and hindwing quite fox-coloured, with 
fine yellow veins, with the same blackish postmedian shadow; discal spot of forewing as in mota, but the middle 
part and the upper branch of the Y filled cpiite black, with an extremely fine yellow vein-line running through. 
Body as in mota. Type: 1 B from Pacho (Eastern Colombia) (Fassl leg.) e Coll. Bang-Haas.
