the $ the red band of the forewing is broader and extends at the costal margin for some distance towards the 
base; the hindwings exhibit also above a red marginal band. Colombia; Venezuela. 
C. lysimachides Druce (23 d) differs from the preceding by the black collar, white forehips, and the 
margin of the hindwing being red also in the Ecuador; Peru. 
C. adamsi Lathy differs from lysimachides by the black head, being somewdiat red only in the neck, 
and by the absence of the red marginal band on the hindwings above; only the fringes are carmine. On the 
forewings the red oblique band at the proximal angle is strongly narrowed and dusted with orange. Fringes 
at the apex white. Ecuador. 
C. eion Druce (26 i) is black, on the body suffused with metallic blue; forehips in the white. 
Forewings at the base and in the cell striped blue; a broad, orange-yellow band extends from the costal middle 
to the proximal angle. The hindwings are of a brilliant blue in the basal halves, at the border there is 
an orange band, not reaching the apex and proximal angle and being expanded to a spot between the median 
veins. Expanse of wings: 42 mm. Costa Pica, Panama. 
Sect. II. forewings with normal veins, but with 2 bare stripes on the under surface of the forewings. 
C. interposita Hmps. Black, with a blue lustre. Palpal base, prothorax, and neck orange, forehead 
bluish-white. Shoulder-covers, thorax, abdomen, and legs striped white. The forewings are striped white on 
the submedian fold; behind the cell, between the lowest subcostal and lower median vein, there is a white oblique 
band. Hindwings of a brilliant metallic blue, fringes white. Expanse of wings: 40 mm. Venezuela. 
C. albicosfa spec. nov. (23 d) is recognizable by the snow-white costal margin of the $ forewing, which, 
however, seems to be soon worn off by flying. The head is quite scarlet, also the palpi, except the black terminal 
joint; forehead, hips and shoulders white. The forewings exhibit a narrow, red oblique band,-in which the 
veins do not appear white; the distal margin of the hindwing is narrow red. Beneath the red bands are somewhat 
broader than above. In the the forehead, forehips, shoulders, and costal margin are black. Obtained in 
numbers of both sexes from Mexico (Presidio, Vera Cruz). 
Sect. III. d forewings normal, without any bare stripes. 
C. fida Hbn. (— atavia Hmps.) (23 d). Black with a deep blue lustre; the 2 first palpal joints, vertex 
and throat carmine. A broad, carmine oblique band behind the cell of the forewing extends from the costa 
to the proximal angle, growing a little narrower from the lower median vein towards the proximal margin and 
being traversed by whitish-dusted veins. The hindwing exhibits a broad, carmine marginal band with an undu¬ 
lated, proximal bordering. Expanse of wings: 50 mm. Widely distributed in Brazil. The statement ,,Mexico“ 
refers perhaps to albicosta. 
C. engelkei Rothscli. differs from fida by its smaller size, quite red palpi, red margins of the collar, 
white chest, and unicolorously brilliant lustrous blue hindwings with red fringes. Length of forewings: 21 mm. 
North Colombia (Sa. Marta). 
C. harnpsoni Dogn. is distinguished by quite unicolorously black forewings with white fringes at 
the apex. Hindwings metallic blue, with a fine scarlet marginal line and red fringes. Beneath the forewing 
shows a broad, red oblique band, the hindwing a broader marginal band. Head black, on the forehead white 
and bluish, the hindhead a little red. Thorax black; abdomen above deep blue, beneath with a metallic lustre. 
Palpal terminal joint black, the two first ones black mixed with red. Expanse of wings: 46 mm. Ecuador. 
C. alcedo spec. nov. (23 d) somewhat resembles Ctenucha virginica and has a black body being suffused 
with a bright metallic greenish-blue. The palpi, except the black terminal joint, a stripe between the antennae, 
the throat, forehips, and neck are orange; of the same colour are beneath the 4 last abdominal rings, the anal 
hairing, and dorsal spots growing larger posteriorly on the 3 last rings above. The forewings are black, at the 
base of a bright bluish-green; in the marginal half between the veins with a dull bluish-green lustre. The black 
hindwings exhibit a very intense, peacock-blue lustre on being exposed obliquely to the light. Fringes of the 
forewings white, ot the hindwings blackish-grey. Under surface like above. Described according to a without 
the patria being stated (Bang-Haas). 
128. Genus: AeBjdsi Hbn. 
This genus contains a number of mostly dark coloured species with a metallic abdomen which is covered 
with long hair at the base. The exhibits a distensible hair-tuft in a fold on the anterior tibiae. On the 
hindwing the lower cell-angle is very much produced, the discocellular forms an acute angle. The lower median 
vein rises far from the lower cell-angle, the upper one and the 3rd radial from it on a long pedicle, and the 
middle radial vein above it.
