rings orange, such is a short stripe at the base of the forewing. Hindwing carmine with a black marginal band.

Proboscis well developed; palpi short, protruding forward. The comparatively short antennae aie 
provided with bristles and cilia in the $, while in the $ they are thickened by rough scales. Posterior tarsi with 
moderately long spurs. The wings are comparatively broad. In the veins there is 1 very little difference with 
Josiodes, on the forewing they are quite the same, on the hindwing the middle radial rises above the lower cell- 
angle — not together with the lower radial — and the costal vein rises much nearer to the base. The genus 
likewise contains quite a number of yellow and black insects which are mostly similar to each other. The $$ 
are often considerably larger than the

diffuse spot in the base of the cell. The forewings are otherwise yellowish-grey with an orange-yellow median 
and marginal band and proximal margin. Hindwings orange, with a brownish-grey marginal band. Expanse 
of wings: 24 mm, $ 28 mm. Colombia. 
C. prusias Drc. (35 i) is orange on its body like the preceding. Forewings black, with a very broad prusias. 
orange band occupying the whole middle of the wing, and a similarly coloured antemarginal band. Hindwing 
orange, in the distal third black. Expanse of wings: 30 mm. Mexico. 
C. menea Drury {— laetifera Wkr., latifasciatus Btlr., arctifascia Btlr., arida Skinner, major Rothsch.) menea. 
(35 i) is a very variable species differing from prusias almost only by the much narrower orange median band 
varying very much in its shape. The ground-colour is sometimes of a deep black colour, sometimes more greyish- 
black. The black margin of the hindwing likewise varies very much in its width. Expanse of wings: 28 to 34 mm, 
$ 40 to 52 mm. Distributed from Mexico to Colombia and Brazil, and very common. -— The larva is light yellow 
with 4 or 5 very h’regular, partly confluent, carmine transverse bands on each ring and very long yellow hair. 
C. cynossema Drc. (35 i) is very much like menea, easily discernible by a large black spot in the basal cynossema. 
part of the hindwing, reaching the proximal margin. Expanse of wings: 34 mm, $ 38 mm. Mexico 
and Guatemala. 
C. quadrifasciata Wkr. (35 i) is smaller than the preceding, more blackish-brown in its ground- quadrifas- 
colour, and distinguished by quite blackish-brown hindwings with an orange spot from the middle of the costal 
margin to the median. Expanse of wings: 30 mm. Mexico. 
C. praxis Drc. (35 k). This species initiates the series of species having the abdomen black above, praxis. 
The forewing is similarly marked as in the preceding species, the discal band is narrow, of an orange-yellow, 
on the median somewhat angled. Hindwing in the basal half orange-yellow, distally black. Expanse of wings: 
28 to 34 mm. Mexico. 
C. cypris Drc. (35 i) differs from praxis by its broader median band, the colour is a deeper orange, cypris. 
The black abdomen is orange towards the base and at the anal tuft. Expanse of wings: 30 to 38 mm. Mexico, 
Guatemala. 
C. unicincta Hmps. (35 k) is distinguished by the entire absence of the orange median band on the unicincta. 
upper surface; beneath there are traces of it noticeable. Hindwings quite blackish-brown. Expanse of wings: 
36 mm. Colombia. 
C. ruficollis Hbn. (35 k) exhibits a broad median band; the antemarginal band is divided into 2 spots: ruficollis. 
a triangular spot below the apex, a smaller one between the median veins. Hindwings dull black with a broad, 
orange median band. Abdomen black, the rings 2 to 6 orange with a black macular stripe. In the $ the markings 
are more yellow. Expanse of wings: 38 to 50 mm. Brazil. 
C. argentinensis Rothsch. (35 k) resembles the preceding and differs by the abdomen being beneath nrgentinen- 
spotted black, the lower marginal spot extending to the proximal angle of the forewing; the hindwings are sls - 
mostly more extensively yellow, but the basal black may also increase and be connected with the marginal 
band by stripes. Expanse of wings: 36 mm, $ 30 mm. Argentina. 
C. cynara Drc. (35 k) exhibits, instead of the orange median band, a broad longitudinal stripe from cynara. 
the base as far as beyond the cell; a narrow antemarginal band like in the others. Hindwing black with an 
orange-yellow stripe in the basal half of the costal margin. Expanse of wings: 36 mm. Mexico. 
C. trisigna Wkr. (35 k) is the smallest species. Markings on the forewing similar as in cynara, but trisigna. 
the longitudinal stripe is divided into 2 small spots. Hindwings orange, with a black margin. Expanse of wings: 
24 mm. Venezuela. 
C. triplaga Hmps. (35 k). Forewings similarly marked as in cyanara, but the marginal band is divided triplaga. 
into 3 small spots. Hindwing black, with an orange spot in and below the cell. The body is black, the collar 
orange; abdomen on the 2nd ring subdorsally spotted orange, the others exhibiting orange lateral stripes 
except the last ring. Expanse of wings: 30 mm. Paraguay.
