C. bricenoi Rothsch. (13 g) looks like a Gymnelia. Head orange with a black spot on the forehead; bricenoi. 
collar and thorax orange and black; the abdomen is black, on the first 4 segments subdorso-laterally with deep 
orange bands; above with metallic blue spots, on the 3 last segments also laterally. Palpi, antennae and legs

the costal margin and a basal inner-marginal spot yellow. Venezuela (Merida). 
C. carabayanum Rothsch. (13 g) greatly resembles the preceding species, from which it differs by carabaya- 
the more golden yellow, black-margined collar and shoulder-covers, and by the quite golden yellow palpi and num.

Colombia; Brazil, p 
C. hampsoni Klages. Differing from the next species by the following marks: palpi quite orange; hampsoni. 
forehips in the $ white; anterior margin of the 4 first abdominal segments above narrow whitish, exhibiting 
for the rest subclorsal black, blue-pupilled spots which are usually flown together into transverse bands on 
the anterior rings. Expanse of wings: 34—48 mm. Venezuela. 
C. nigricornis F. (= stretchii Btlr.) (13 h). The head is yellow, on the vertex black with blue spots; nigricornis. 
palpi with black terminal joints; collar and shoulder-covers yellow and black striped. Thorax above black 
and blue spotted, beneath with yellow, in the $ also above with yellow spots. Abdomen yellow with black 
transverse bands being subdorsally blue-spotted. In the $ these are narrower than in the <J. Wings yellowish 
hyaline with very narrow blackish margins and small apical spots. Costal and inner margins in the $ faintly 
yellow, in the $ intensely yellow. Colombia, Venezuela. 
C. sephela Druce (13 g) differs from the preceding by a white-spotted first abdominal ring, much sephela.

C. villia Druce (13 h). The body, inclusive of the antennae and legs, is brownish orange-yellow; in villia. 
the neck two black dots; collar black, bordered with yellow. The margins of the abdominal segments are finely 
bordered with yellow and black; the abdomen exhibits small, subdorsal, metallic silvery-blue spots. V ings 
yellowish hyaline, only the fringes are black. Expanse of wings: 40 mm. Differing from the similar sephela 
chiefly by its larger size and the absence of the white basal spot on the abdomen. Peru.
