small stripes at the sides of the 3 first segments reduced. The legs are quite black except the red hips, the 
large ventral valve of the $ is almost quite silvery white. Veins and margins of the wings are-much broader 
black, particularly the middle spot is very large. Occurring in Mexico, Guatemala and Panama. 
C. rubriguttum Skinner greatly approximates the preceding, but it also comes near the following rubriguttum. 
by the hindwings being orange-red in the basal part and distally black. Collar and shoulder-covers are orange, 
the rest of the thorax black, blue-spotted like the head. Abdomen black, blue-spotted; legs blackish-brown. 
Wings like in auge, but the red colour replaced by orange and the discal spot pupilled in orange. Expanse of 
wings: 40 mm. One specimen taken in August in Arizona. 
C. cardinale Hmps. (13 d) is a magnificent and scarcely mistakable species owing to the broadly cardinale. 
carmine inner-marginal area of the hindwing. Body black, collar with 2 white dots, shoulder-covers striped 
red. The abdomen is laterally red-spotted at the first 3 rings; the dorsum exhibits one row, each of the 
sides two rows of white dots; the middle spot on the first abdominal ring is the largest. Apparently not rare 
in Brazil (Sao Paulo). 
C. erythrarchos Wkr. (= vulneratum H .-Schaff .) (14 m) resembles the preceding and differs by erythrar- 
subdorsal abdominal spots on the 3rd ring; the red lateral spots are confined to the first ring on which we 
notice, instead of one dorsal, 2 subdorsal, white streak-spots; only the last rings exhibit above insignificant, 
small white spots. In the hindwing the inner-margin is much less extensively red. Venezuela; Brazil (Rio 
de Janeiro). 
C. xanthistis Hmps. (13 e). Head black, forehead in the shape of a horse-shoe being open above, xanthistis. 
white. Antennae black with white tips. Collar black, on the shoulders a white dot. Thorax and shoulder-covers 
orange-yellow. Abdomen black, the first 3 rings above with orange-yellow hair, the other rings exhibit white, 
dorsal, lateral and sublateral spots. The wings are yellowish diaphanous with black margins, the bases of the 
costal and inner margins orange. Brazil (Sao Paulo, Santos). 
C. rosenbergi Rothsch. (13 e) resembles the preceding from which it differs by its quite black thorax rosenbcrgi. 
with a white middle-spot, by the absence of the white dorsal spots on the black part of the abdomen, as well 
as by the yellow colour being absent at the bases of the wings, at the costal and inner margins. The $ has 
only the 2 last abdominal rings black. Ecuador, Colombia. 
C. hanga H.-Schaff. (= arauna Wallgr.) (13 e) has a black-brown body, spots on the shoulder-covers lianga. 
and subdorsal spots on the first, 3rd and 4th abdominal rings are orange. White-coloured are the tips of the 
antennae, spots on the head, collar, legs and abdomen. The species is easily recognizable by the very large 
orange spots at the bases and inner margins of both the wings. The extreme apex of the wings is white. 
Occurring from Brazil as far as Argentina. 
C. leuconoton Hmps. (13 e). Body blackish-brown; the base of the shoulder-covers and metathorax leuconoton. 
white-spotted; the first abdominal ring exhibits one large dorsal, the second 2 subdorsal, white spots; the 
penultimate segment exhibits orange and red subdorsal spots, the last being blue-spotted. At the base of the 
forewing there is a carmine spot; the distal margins and apical spot blackish-brown. Colombia. 
C. melathoracia Kaye (13 e). Body black. Forehead and neck with bronze-green spots; similar dorsal melathora- 
spots of a square shape are exhibited by the abdomen the first segment of which shows subdorsal brick-red cia - 
spots. From Trinidad. 
C. rica Dogn. Body pale metallic bluish green, interrupted by black; the 1st abdominal ring is rica. 
yellow, the under surface inclusive of the legs black, the forehips white. Wings hyaline, finely bordered with 
black, with a black cell-spot, and apical spot. Expanse of wings: 29 mm. Ecuador (Loja). 
C. stryma Bruce (26 k). Blackish-brown with carmine spots on the base of the shoulder-covers and stryma. 
1st abdominal ring. The ends of the tarsi white. Wings hyaline, with narrow brown veins, margins, apical 
and discal spots. Expanse of wings: 22 mm. Known from Mexico (Orizaba) and Nicaragua. 
C. gracula Dogn. Body black, with metallic green spots. The first abdominal ring exhibits a large, gracula. 
square, red spot, the following ones at the sides double metallic-green transverse bands. Hips and end of abdomen 
beneath white. The hyaline wings are bordered with black, the forewings at the base with a red basal spot; 
at the cell-end there is a broad black transverse band. Expanse of wings: 31 mm. Colombia. 
C. lycopolis Druce (13 e). Body black, antennae only at the base black, otherwise orange. Head, lycopolis. 
collar, shoulders and metathorax blue-spotted, as well as the legs; the ends of the tibiae and the tarsi orange, 
posterior hips yellow. The abdomen being subdorsally blue-spotted exhibits on the first and last rings dorsal 
yellow spots, from the 2nd to 5th rings yellow lines. Ventral valve bordered with yellow, behind it sublateral, 
yellow spots. Wings hyaline with narrowly black veins and margins; subcostal and inner-marginal stripes 
orange; apical spot scarcely noticeable. Expanse of wings: 36 mm. Ecuador.
