nobilis. C. nobilis Schaus. Body black, forehead, collar and thorax with metallic blue spots, on the meta- 
thorax a large spot of a white and blue opalescence. On the abdomen the hind-margins of the segments are 
narrowly yellow; at the sides there are blue transverse lines and sublateral blue spots, the 2 last rings are quite 
blue; the 1st ring exhibits above 2 opalescent spots, wings hyaline with black veins and margins, discal and apical 
spots; the base of the forewing is blue-scaled below the costa and cell. Expanse of wings: 44 mm. Costa Rica. 
cinctum. C. cinctum Schaus (13 f) differs from the allied similar species by orange-yellow costal- and inner- 
marginal stripes, as well as by the black and white forehead, also the tips and base of the antennae are in front 
white. The thorax is in the middle quite black. The first abdominal ring exhibits above a white band. Venezuela 
(Aroa). 
gaza. C. gaza Schaus approximates the following, being distinguished by the deeper orange-red colouring 
of the yellow parts, the first abdominal ring exhibiting a whitish band; the black and blue bands on the following 
rings are expanded into dorsal spots. Palpi orange and black; the thorax is black, blue-spotted. Expanse of 
wings: 42 mm. Peru. 
tarapotense. C. tarapotense Druce (13 f). Head and thorax black; palpi, forehead and vertex yellow; collar black, 
margined by yellow; shoulder-covers yellow striped; abdomen black with blue subdorsal spots, segmental inden¬ 
tations yellow; underneath black, ventral valve margined by yellow; a band behind it yellow. Legs black and 
yellow. The hyaline wings exhibit narrow black margins and orange-yellow inner-marginal stripes. Peru 
(Tarapoto). 
simillimum. C. simillinium Rothsch. (13 f) is extremely similar to the preceding; different by a yellow, not black 
margined collar, with a black median spot, the black thorax with a yellow band and quite orange-yellow legs. 
Amazon. 
steinbachi. C. steinbachi Rothsch. (13 f) likewise resembles the preceding; forehead yellow, vertex black and 
blue; collar yellow with a black spot; the first abdominal ring quite yellow, the black bands much broader. 
Bolivia. 
mctallicum. C. metallicum Rothsch. (13 f). Head and thorax metallic bluish-green, with black margins. The 
abdomen is black with subdorsal and sublateral rows of metallic bluish-green spots; the first 4 segments exhibit 
orange segmental indentations. Legs black, with metallic greenish-blue spots. Wings yellowish hyaline, costal 
margin orange, margins and a large apical spot black. Bogota; Amazon (?). 
jlavicostale. C. flavicostale Rothsch. (13 f) has a black body; at the base of the brown antennae a small white 
spot; collar with metallic blue spots; shoulder-covers yellow with black distal margins; on the black thorax 
a yellow middle line; the abdomen with a steel-blue reflection, on the first two segments pade-yellow, on the 
3 next ones orange curled. Legs black with yellow tarsi, forehips white-spotted. Wings yellowish-hyaline, 
at the costal and inner margin orange. Peru. 
mcridense. C. meridense Rothsch. (13 f). Head and collar orange; thorax black with orange stripes; abdomen 
deep steel-blue with narrow, orange-yellow rings at the segments 2 to 4. On the yellowish, hyaline wings the 
basal half of the costal margin is orange-yellow; distal margins narrowly black. Venezuela (Merida). 
ichneumo- C. ichneumonoides Rothsch. (13 f). Head and thorax are reddish orange, like the legs and antennae. 
noides. Abdomen black; the 1st segment and transverse bands on the 2nd to 4th are orange. The wings are quite faintly 
yellowish hyaline with orange veins; the base, costal and inner margin and the transverse vein vermilion. 
Described from East Bolivia. 
flavitarse. C. flavitarse Wkr. (= scintillans H.-Schdff.) (13 g). Similar to the following. Body black; forehead, 
margins of the collar, spots on the thorax and the shoulder-covers, sides of the thorax, small spots on the legs 
and posterior tarsi and narrow rings on the abdomen are yellow: metallic blue spots are noticed on the vertex, 
collar, thorax, forelegs, and subdorsally on the abdomen. Forehips, inner side of the femora and margins of the 
ventral valve white; apex of abdomen below yellow. The yellowish hyaline wings have narrow black veins and 
margins; the latter at the apex somewhat broader. The forewings exhibit at the base a blue spot. The marginal 
band of the hinclwing is somewhat broader at the inner angle. Colombia; Venezuela; Brazil. 
hentrix. C. beatrix Druce (= scintillans Druce ) (13 g) differs from the preceding by the black, metallic blue 
spotted forehead; besides it is mostly larger, the wings have a more yellowish tinge and a scarcely noticeable 
apical spot. On the abdomen only the 3 first rings are curled orange-yellow; in the $ the anal apex is orange- 
jactans. yellow. Costa Rica, Panama. — In jactans form. nov. (= ab. 1. Hmps.) the shoulder-covers are bordered with 
orange; the blue of the abdomen is confined. 
gitapila. C. guapila Schaus. Much smaller than the preceding. The abdomen exhibits only at the 3rd and 
4th segments pale reddish-yellow rings. Instead of the subdorsal blue spots there are here dorsal and lateral 
rows; the last segment is orange-red. Hips, anterior tibiae and posterior tarsi white. Expanse of wings: 29 mm.

harom. C. baroni Rothsch. (13 g) strikingly resembles certain species of the genus Sarosa. The body is jet-
