C. cinctutum Schaus differs from the preceding species by orange, black-bordered collar and shoulder- cinctutum. 
covers; the first abdominal ring is quite orange, above parted only by a narrow black dorsal line; dorsally there 
are also blue spots, dying away on the 3rd and 4th rings. Legs orange, with some black stripes. Wings not 
so yellowish hyaline, otherwise like in saron. Costa Rica (Juan-Vinas). 
C. bolivari Schaus (13 k) is a small species with a black head and thorax; collar and shoulder-covers bolivuri. 
orange. The abdomen is orange; the first segment exhibits a black dorsal spot, the 3 next ones are above quite 
black, narrowly margined by orange, the 5th is orange, narrowly bordered with black, the next 2 are again 
black, the anal apex orange. The costal margin of the hyaline forewings is orange, the margins and apical spots 
otherwise black. From Ecuador (Bolivar). 
C. plebecula Dogn. differs from the preceding by its entirely yellow thorax and the absence of the plcbecula.

C. chiriquensis Rothsch. (13 k). The head is black, thorax and abdomen golden-yellow, the latter chiriquen- 
above on the 2nd and 3rd segment black, also the two last rings are black. Legs and antennae are black. Base 
of forewing yellow, bordered with black. Panama (Chiriqui). 
C. corvicum Dogn. Body black, tips of antennae white. Head, collar and thorax with metallic green corvicum. 
spots. The 2 first abdominal rings exhibit lateral large metallic green spots, the last rings exhibit a dorsal green 
lustre. Venter black, the first ring green, the 2 following ones white-striped. Wings hyaline with black veins 
broad margins and apical spots, and a large discal spot on the forewing. Expanse of wings: 26 to 33 mm. Bolivia 
(Corvico). 
C. pheres Cr. Like the following, but somewhat smaller and the abdominal spots of a pure metallic pheres. 
blue; the white lateral spots on the 2nd ring are absent. Expanse of wings: 28 mm. Brazil (Rio de Janeiro). 
C. metallescens Men. (= pheres var. Wkr., chalcosticta Btlr.) (13 k). Black, head, thorax and metalles- 
abdomen on the dorsum and on the sides with metallic bluish-green spots. Forehead, forehips and ends of 
tarsi white. Distinguished from the similar species by the intense golden green reflection of the metallic spots, 
as well as by a white spot at the sides of the 2nd abdominal segment, from xantliostictum (13 1) particularly 
by the white forehead. From Mexico, Panama, Amazon, Para. 
C. batesi Btlr. (13 k) has a unicolorously orange-yellow body; the palpi are either yellow or black, batesi. 
or yellow with a black terminal joint; the forehead is white, vertex and antennae black. Bases of the wings 
orange, which colour usually extends for a short distance along the costal and inner margin, but may also be 
confined to a minute spot at the base. Brazil (Sao Paulo). 
(?) C. bromus Cr. Head, thorax and abdomen are dull yellow, wings hyaline with black veins and bromus. 
margins, as well as large apical spots. Expanse of wings: 36 mm. — This species originally described from Surinam 
perhaps does not belong at all to the genus Cosmosoma. 
C. melanopera Hmps. (13 k) has an entirely scarlet body, only the head and anal segment are black, melanopera. 
the forehead white. The forewings exhibit at the base a small red spot. Described from Bolivia (San Jacinto, 
Bueyes), but it is before me also from Manaos, Amazon. 
C. coccinifera Dogn. (13 1). This tiny species has a jet-black body with a blue lustre; the forehead coccinifera. 
is white; collar and shoulder-covers are of a deep scarlet, finely bordered with black. The abdomen on the 
first 5 rings exhibits large triangular scarlet subdorsal spots; the ventral side of the first 4 rings and the hips 
are white. Before me is only a male specimen; the description referring to a $ mentions besides a series of 
sublateral red spots on the 4 first abdominal rings; the forehead is said to exhibit a green reflection. East 
Colombia (Medina). 
C. phoenicophorum Dogn. (13 1) presumably is the smallest species with a blackish-brown body; 
collar, lateral stripes on the 4 first abdominal rings, as well as the inner-marginal area of the hindwing are rosy- 
red, also a narrow basal inner-marginal stripe on the forewings. The wings are hyaline, with very broad brown 
distal margins and a very large round discal spot, also the bases of the wings are brown. Colombia (Medina).

C. colona Schaus. Body black, tips of antennae white. Forehead, collar and shoulder-covers are of colona. 
a deep metallic blue lustre. The abdomen exhibits subdorsal, blue, transverse streaks, on the first ring white 
lateral spots; the 2 last rings are red. The wings are hyaline with black veins, margins and apical spots. Expanse 
of wings: 33 mm. Costa Rica. 
C. plutona Schaus (13 1). Head and thorax black, vertex and collar blue-spotted; abdomen above plutona. 
deep carmine. The hyaline wings have rather uniformly broad black margins; the subcostal space as far as 
the middle-spot hyaline. Brazil.
