C. fenestrata Drury (= steropes Goze, rubripeda Lucas) is presumably the largest Cosmosoma, with 
an expanse of 62 mm. The body is black, palpi, legs and venter scarlet. The black wings exhibit a hyaline 
spot in the cell-end and a larger one below it, as well as a curved row of spots behind the cell between the lowest 
subcostal vein and the lower median vein. Hindwings whitish hyaline, costal margin, cell, veins and marginal 
band black. Jamaica and Cuba. 
C. seraphina H.-Schafj. (13 i). Head black, thorax carmine with 2 black spots on the mesothorax. 
Abdomen black with red lateral stripes and 2 white dorsal stripes on the first segment. Wings hyaline with 
black veins, margins, apical and inner-angular spots, as well as red costal- and inner-marginal stripes-. Expanse 
of wings: 26 mm. Amazon. 
C. tigris Schaus (13 h). Body black, palpi in front orange. Forehead, vertex, collar and metathorax 
blue-spotted. Collar, shoulder-covers and thorax with orange spots. Breast and legs with orange stripes. The 
abdomen exhibits above orange spots which turn to broad bands on the 4th and 5th rings. On the first 3 rings 
orange lateral spots, on the others lateral and sublateral blue macular series. V ings hyaline with black veins, 
broad margin and apical spot; on the forewings the subcostal area and 2 stripes at the base of the inner margin 
are orange, on the hindwing the inner-marginal part is the same. Expanse of wings: 36 mm. Venezuela. 
C. cermena Dogn. (13 i). Front body black with metallic blue spots; shoulder-covers yellow, bordered 
with black. The 4 first abdominal rings are above yellow with a dorsal black, blue-pupilled spot; the rest of 
the abdomen is black, with dorsal and lateral, metallic bluish-green spots. Forelegs black with bluish-green hips, 
middle-and hind-legs black with yellow tarsi. Antennae black with white tips. Wings like in tigris. Ecuador (Loja). 
C. dubium Bothsch. (13 i). Head and thorax are black, with metallic blue spots, the shoulcler-covers 
of a brilliant yellow; the abdomen is yellow, the 3 last rings black with subdorsal blue spots; the other segments 
exhibit triangular black, blue-pupilled dorsal spots; the spot on the first ring is larger than the others. The 
forehips are metallic blue, the legs blackish-brown, except the posterior tibiae and tarsi which are yellow. Costal 
and inner margins are yellow, also the distal margin is partly yellow. Jamaica. 
C. mathani Bothsch. Head metallic blue, antemrae black with a white apex, palpi black; thorax black, 
with metallic blue spots, beneath golden orange and black. Abdomen golden orange, the first and the 4 last 
rings above black; dorsal and lateral metallic blue longitudinal stripes in the $ run over the whole abdomen, 
in the $ only on the black rings. Wings hyaline with black veins, margins and apical spots. Length of forewings: 
21, ^ 24 mm. Cunclinamarca. 
C. contractum Whr. (13 i). This and the following species resemble each other very much. The body 
is black; forehead and vertex, collar and shoulder-covers, as well as metathorax and base of the forewing with 
metallic blue spots; the abdomen shows on the 3 first rings bluish-green silvery subdorsal and sublateral spots 
and on the 2 last segments blue subdorsal spots. A characteristic of the species is that the orange subcostal 
stripe extends into the black apex of the forewing and the orange colour extends at the inner side of the apical 
spot down as far as about the lower radial; proximal margin broad orange; the wings themselves are somewhat 
yellowish. The teeth of the antennae orange. Brazil. 
C. gemmatum Btlr. (13 i) is easily separable from the preceding very similar species by the shorter 
orange costal-marginal stripe which does not extend into the apex of the wing, which is here quite black, inwardly 
not with an orange tint. Besides the metallic blue abdominal spots are large and more intense, and are on all 
the segments, only on the 4th they may be absent. The <$ exhibits on the ventral side of the 3rd segment 2 
yellow spots. Panama, Colombia, Venezuela, Peru (Cuzco). The species seems to vary considerably. -— f. 
xanthocera Hmps. (13 k) which was originally described as a species and in fact looks very differently, according 
to Klages who often found it in Venezuela, also in copula with gemmatum, is only a form of it; both have the 
same habits. The palpi and antennae are orange, the collar orange with blue and black spots, the shoulder- 
covers with orange-stripes; also the thorax is posteriorly spotted orange; the abdomen exhibits on the 
3 first segments dorsal and lateral orange spots, the 4th and 5th segments with orange bands. Occurs in Venezuela 
as well as in the Amazon District. 
C. deyrollei Wkr. (13 i). The blackish-brown body exhibits white lateral spots on the abdomen and 
dorsal spots on the 3 penultimate rings. The yellowish diaphanous wings show narrow black margins as well 
as orange-yellow costal- and inner-marginal streaks. Hitherto known only from Brazil (Rio Grande do Sid and 
Sa. Catharina). 
C. saron Druce (= meres Druce ) (13 k). Body black, forehead white, vertex metallic blue; thorax 
with blue spots. Abdomen with subdorsal and sublateral blue macular series and small subdorsal orange spots 
on the 1st and 4th rings. Wings yellowish hyaline, veins and margins, as well as apical spot black; the forewing 
with a golden yellow subcostal stripe and basal inner-marginal spot. Expanse of wings: 30 mm. Panama 
(Chiriqui).
