ochreous with black rings. Wings white, the forewing at the apex and margin broad smoke-brown, between 
2 and 4 somewhat narrower. Costal margin black, veins especially towards the margin smoky, at the cell-end 
a small black spot. Hindwing all white with a narrow smoke-brown marginal line. Type: l $ from Mexico in 
the Berlin Museum e Coll. Maassen, on the label “ Heliconisa albata ” has been written. I could not discover 
any description. 
VIII. calchas-group. 
D. calchas Stoll (117 A b) is the chief representative of a group of allied species the $<3 °f which mostly calchas. 
exhibit a dark triangular spot at the costal margin, whilst the $$ have a broad median band instead of it. 
Anterior body dark brown, abdomen reddish-yellow, with broad black bands. Fore wing greyish-brown with 
a dark basal spot which is outside white-haired, a dark discal spot and above it a mostly small dark brown 
triangle with whitish edges; subterminal line dark, distally with a more distinct undulating border, receding 
between 4 and 6, proceeding between 2 and 4 in two obtuse bows. Hindwing basallv bright red-brown with 
a large dark discal spot, a black postmedian line behind which generally a lighter band follows and then a 
darker subterminal band. The costal triangular spot may be almost quite absent, but also fused with the 
discal spot. The $ is mostly of a duller greyish-brown with 2 dark transverse lines bordered with whitish on 
the averted sides. Hindwing in the basal half less bright red-brown. Brazil (Sa. Catharina; Rio Grande do 
Sul; Porto Alegre). 
D. rothschildi Dogn. (117 A b) is very similar to calchas , but easily discernible by the almost entirely rothschildi. 
black hindwings, and the black abdomen showing only very narrow brownish rings. Thorax and the oblique 
basal area much deeper black. The discal spot of the forewing is larger and black, mostly coherent with the 
black costal-marginal triangle. Brazil (Sao Paulo; Joinville). 
D. fornax Drc. was not before me; it must be extraordinarily similar to rothschildi. Body blackish- fornax. 
brown, abdomen with long grey hairs. Forewing reddish-brown, densely strewn with grey, with a black oblique 
basal spot, a large black triangular spot in the centre of the costal margin and a round discal spot below it. 
Hindwing blackish-brown, in the distal half more reddish-brown, strewn with grey, with a narrow dark brown 
submarginal band therein. Under surface dark greyish-brown, with a narrow greyish-white median line. 
Expanse of wings: 4 y 2 ins. Southern Brazil (Rio Grande do Sul). 
D. thliptophana Fldr. (117 Ac) is extremely similar to calchas , the costal-marginal spot sandglass- thliplopha- 
shaped, with or without a white central spot therein, the lower edge of the spot extending from proximally 
below obliquely, in a straight line upward distally. Hindwing almost exactly as in calchas. Weymer described 
a specimen as the $ of it, which, however, according to the description I consider to belong rather to the ursina- 
group. The $ described by him probably also belongs rather to calchas. Amazons. 
D. fraterna Fldr. (117 Ac) is very similar to the preceding species. Fore wing more cinnamon-brown fratema. 
with a pink tint, the large discal spot is very broad at the costal margin, in the middle slightly strangulated, the 
lower edge with an almost rectangular point extending down to vein 2, bordered with whitish, with a white 
angular or comma-shaped streak near the exterior edge or also only a small white spot; marginal area lighter 
towards the subterminal shadow which is indented between 4 and G. Hindwing as in the preceding species, 
with much duller transverse lines; a dark discal spot with a light ring may be present or absent. Amazons 
(Iquitos; Matto Grosso); Peru. — A Colombian form: callosa f.n. (117 Ac), from Villa vicencio, has broader callosa. 
wings and is more greyish-brown, the hindwing also without any red-brown; discal spot of forewing much deeper 
strangulated, producing outside and inside almost right angles; the enclosed white central streak is therefore 
also rectangularly flawed, the lower branch yellowish-brown, finely filled with black, only the upper branch 
white; marginal area with a yellowish ochreous tint. Hindwing beneath with a broad lilac white, distally 
concave median band which is only indicated in the typical form. 
D. javarina Btlr. was not at hand; it is allied to avia and concolor. Forewing above light cinnamon javarina. 
pinkish brown, with a broad chocolate median band, at the costal margin thrice as broad as at the inner margin, 
the proximal border oblique and undulated, the distal border straighter; base dusted with brown, the basal 
area itself black, outside bordered by a white line; subterminal band darker brown, expanded in its upper 
quarter, apex before it mixed with yellowish. Hindwing basally reddish-brown, distal half more pinkish-brown, 
inside regularly bordered by the ground-colour. Thoarx dark chocolate, al) do men rusty brown, laterally deep 
red, at the base with 2 black belts. Expanse of wings: 5 ins. 4 lines. Rio Javary. 
D. avia Stoll and the following forms of it are rather variable. Dr. Jordan writes to me that Stoll’s avia. 
figure is inaccurate and the 3 bands on the hindwings are a mistake of the painter, since the hindwing above 
exhibits but one distinct blackish submarginal band, though between it and the cell there are sometimes traces 
of another band, and the 3 bands of Stoll are to be explained by the darkening of the centre of the wing. In 
the British Museum, according to the kind information by Tams, avia is united with orasia Stoll ; he says that 
the figure of orasia has been made from a very small $ or from a $ without antennae which the artist has 
added according to his own opinion. — avia Stoll (= orasia Stoll, concolor Wkr.) (117 A d) is the oldest form avia.
