Drc.; they have a narrower band of the forewing, though there occur all kinds of transitions to the type, so 
that the race is hardly tenable. Also from Bolivia. 
S. poliana Drc. (71 k). Like the preceding species, with white, broader, hardly undulating bands, 
hindwing somewhat purple blue. In the Berlin Museum there is also a $ from Massauary, corresponding to 
the $, the shape of the body similar to rejecta. Guiana, Amazons. 
S. dilatata Wkr. (71 k). In the forewing the 1st cubitus is forked, in contrast with the preceding 
species. Abdomen not extending beyond the hindwing. Eorewing oblong rounded, veins lighter. Amazons. 
35. Genus: CSetta Wkr. 
In the hindwing the radial ramus and the 1st median are fused. The cell of the forewing in the A is 
very short and narrow, hindwing with a scent-organ at the costal margin, also the 2nd median fused wdth 
the 1st. 
G. ennia Drc. Black with a pale yellow cross-band of the forewing. Brazil. 
G. elite Wkr. (= niveifascia Wkr.) (71 k). Like ennia , cross-band white. Brazil, Ecuador, Bolivia, 
Southern Peru. — probles Prt. is larger, the cross-band is twice as broad. Eastern Peru. 
G. baetifica Drc. (71 k). Cross-band yellow, wings partly suffused with blue. Colombia, Peru, 
Ecuador. 
36. Genus: Antieoreiira Prt. 
In the forewing the 5th radial rises before the 2nd; 1st cubitus not forked. 
A. salmoni Drc. Forewdng blackish-brown, with a red cross-band, hindwdng black, suffused with blue. 
Colombia. It strikingly resembles certain Syntomidids ( Coreura). 
37. Genus: Polyp tycilia Fldr. 
In the forewdng the 5th radial rises before the 2nd; 1st cubitus forked. with scent-tufts on the 
hindwing and hind legs. 
P. fasciculosa Fldr. Blackish-brown, forewing with a yellowish-white cross-band. Colombia, Venezuela. 
— In ceron Drc. (71 k) the band is yellow; in the $ at the apex of the hindwing a yellow spot. East Colombia, 
Upper Amazon R. — In unicolor sp. n. (perhaps only a form of ceron ?) the yellow band of the forewing is 3 mm 
broad (in ceron 2 mm). Hindwing above and beneath without the yellow apical spot. $ type from Yurimaguas 
in the Berlin Museum.
