Q. Forewing olive-brown, with or without isolated small light spots. Hindwing reddish and yellowish, with brownish 
black sublimbal spots. 
C. archon Burm., from Catamarca in Argentina, is compared with C. therapon, but is twice as large, archon. 
Colour greyish yellow suffused with brown, forewing with white fringes, brownish black median longitudinal 
band and hind border. Hindwing orange-yellow with narrow black marginal baad, fringes as in therapon, in the 
middle a large black smear which is interrupted in the centre by six oval wihtish spots forming a sinuous 
transverse band. Underside of wings and body lighter greyish yellow, both wings orange at the base, hindwing 
with indications of the markings of the upperside. 
C. amalthaea Druce, from Brazil, has the forewing dark brown, bearing two white transverse bands amalthaea. 
shortened posteriorly. Hindwing orange with a black spot at the apex of the cell and a similar one between 
the latter and the inner margin; a sublimbal row of black spots having white pupils, and a black marginal line 
present. Fringes of both wings brown and the underside orange-red. Body above light brown beneath orange- 
red. Expanse 76 mm. 
C. fonscolombe Oodt. (= japyx Hhn., kirsteni Thon, walkeri Buchecker) (5 b). Brazil. The $ differs from fonscolombe. 
the <$ (5 b) in the presence of 5 small light spots on the forewing. 
R. Hinclwing with a magnificent blue sheen, and red marginal band. Forewing dull black, with light greyish band 
and small silvery glossy spots. 
C. diva Btlr., from Colombia and Central America, varies rather strongly. Tie red marginal band of diva. 
the hindwing, continuous in true diva, is sometimes separated into spots; form maculifera form. nov. (6 d, on the maculifera. 
plate as diva)-, — tricolor Fldr. (6 d) is a form with the markings particularly sharp. — A form from Chiriqui tricolor. 
is before me which has the band of the forewing much darkened (dark brown) and indistinct, and only one or 
two small silvery spots. This is chiriquiensis form. nov. The variability in size is also remarkable, there are chiriquien- 
before me <$<$ of chiriquiensis from 55 to 90 mm (the type is 55 mm). SiS - 
S. Hindwing black, usually with red spots; forewing with irregular white postmedian band from the anal angle about 
vertical to the costal margin, in the costal area on both sides of and parallel with it a white stripe. The insects resemble 
Synemon. 
C. amycus Stoll (5 d), widely distributed in South America (according to Kirby’s Catalogue also in amyous. 
Central America), varies considerably. — tristicula form. nov. is a form of which I have as yet only seen tristicula. 
cJd; the red colour in the disc of the hindwing is obsolete and the red submarginal band on the same 
wing at most present in the dorsal area; from Blumenau, Espirito Santo, etc. -— alboinsignita form. nov. alboinsig- 
(5d) has the transverse band of the forewing broad and pure white, a white submedian costal transverse spot in nita - 
the forewing is at most indicated, the subapical costal transverse spot, however, is larger and the red markings 
on the hindwing are different. 
C. meditrina Hpffr. (5 d), from Brazil, on the whole has the hindwing more blackish than our figure meditrina. 
indicates. 
T. Forewing greyish black with four whitish transverse bands; hindwing in. the basal half white with black spot 
edged with red, in the apical hah black with red and white markings. 
C. juturna Hpffr. (6 b), from Minas Geraes and Rio Grande do Sul; a rarer species. Our figure (6 b), juturna. 
which, like many others, is a copy from Preiss, is unfortunately not quite exact, in so far as there should be two 
more light postmedian transverse bands present in the forewing (as in Hoppfer’s figure), which are, however, 
not as distinct as the two present in our figure should be. Preiss’s original type is before me ; it is somewhat worn 
in the apical area of the forewing, but both the bands missing in the figure are distinctly recognisable. Accord¬ 
ing to Burmeister (Descr. Rep. Arg. Lep. Atlas, p. 57) a form occurs in Paraguay which is somewhat smaller 
than the original figure and the black marginal band on the hindwing of which is interrupted by two rows 
of white red-edged spots parallel with the margin (paraguayensis form. nov.). paragua- 
yensis. 
U. Forewing similar to that of the preceding group, but only two light transverse bands present. Ground-colour 
of hindwing white or black, with white spots edged with red and black, margin always black. 
C. endelechia Druce (6 c), from Paraguay, is easily distinguished by the white ground-colour of its hind- endelechia.

C. eudesmia G. B. Gray (8 e), as in this species the hindwing is black with a red postmedian band eudesmia. 
enclosing white spots and a sublimbal row of red spots each enclosing a white one. In the $ there is an orange- 
yellow discal spot. Chile. — Larva in the trunk of a Bromeliaceae, Pourretia coarctata (cf. Philippi 1863, 
Butler 1882, Crowley 1894). 
W. Wings black, forewing with grey oblique band, hindwing with white median band and with or without white sub¬ 
limbal spots. Abdomen with red transverse bands. 
C. garbei Foetterle (6 d), from Southern Brazil, strongly resembles garbei. 
C. cochrus F. (8 c), likewise from Brazil (the habitat Chile in Kirby’s catalogue is erroneous); but in cochnis. 
cochrus the white band of the hindwing is much broader and situated before the middle of the wing, the light 
band of the forewing is not so distinct as in garbei and in the hindwing there are fewer (apparently at most 4)
