 Oberth. The submarginal spots between the 2. and 3. radial of the forewing separated by a corresponding 

 discal spot, discal band usually interrupted at the 3. radial, the 1. submarginal spot is absent or small. Eastern 

 slopes of the Andes from North Ecuador to Central Peru, Upper Amazon. — zoros li. & J. Like the preceding ; zows.

 {= diaphorus Hbii.) (16b). Paler yellow than the Andes forms; discal band of the forewing not interrupted, 

 or only very slightly, the submarginal spot between the 2. and 3. radials quite close to the discal spot or 

 parti}' merged together with it; the black discal area of the hindwing not entering the cell. Southern 

 Brazil, only known from Sao Paido to Rio Grande do Sul. 



P. dioxippus Hew. (16c). Wings on the upper surface mth common green-yellow triangular area; dioxippus. 

 forewing with vestiges of costal bands; hindwing with 2 red spots at the anal angle. — Very common in 

 Bogota-collections; Vallejs of the Gauca, Magdalena and Meta Rivers, at moderate elevations. ? not known. 



P. lacandones. The discal area of the forewing extends costad to the lower angle of the cell or 

 beyond it. Guatemala to Boli'via. ? not known. — lacandones Bates from Guatemala and Panama. Fore- lacandones.' 

 wing with 4 thin submarginal spots, discal area extending anteriorly beyond the 2. radial. — diores B. & J. diores. 

 (16 b). Forewing broader, with 5 submai'ginal spots which are larger than in the preceding subspecies, discal 

 band not extending beyond the 2. radial, the subapical spot of the cell much smaller than in lacandones. 

 Eastern slopes of the Andes of Ecuador, Peru and Bolivia. 



P. calliste. Bands and spots of the wings pale yellow or greenish yellow, similarly arranged as in 

 dioxippus; submarginal row of the forewing curved; hindwing with 2, rarely 3 red spots, and with 2 very 

 large greenish yellow margmal spots from the 2. radial to the 1. median; underside of the hindAving with 

 pale marginal band. ? not known to us. Mexico to Costa Rica. — calliste Bates (== lorzae Boisd) (16 b). calliste. 

 The two outer cell-bands of the forewing clearly developed and the last but two more or less indicated, the 

 discal area eraarginate at the cell before the 2. median. Western Mexico, Guatemala and British Honduras. 



— olbius B. & J. Larger than the preceding form ; also the outer cell-bands of the forewing suffused with olMns.

 one another. Eastern slopes of the Andes, from Ecuador to Bolivia. 



DoMcaon-Group. 



The 7 following Papilios form the dolicaon-grou]}. In tliese species no red or yellow band is present on 

 the under surface of the hindwing. In some species only the 1. subcostal of the forewing is eonfluent distally with 

 the costa, whilst in others the 2. subcostal also anastomoses with it. 



P. serville. Forewing with broad black cell-band, which runs obliquely from the costal margin to 

 the marginal area, being united with the latter. In the forewing the 1. and 2. subcostal distally confluent 

 with the costa, the 2. subcostal rarely free. ? not known. North Venezuela, Colombia to Bolivia. Common. 



— acritus B. & J. The spots on head and breast small, also the yellowish lateral stripe of the abdomen acritus. 

 reduced, these markings sometimes absent; cell of the hindwing usually without blackish streaks. North 

 Venezuela, East and Central Colombia. — serville Godi. (= servillei Boisd., boliviana Weeks) (16c). The serville. \ 

 spots on breast and head always present, abdomen with 2 yellowish strijjes on each side, of which the 



upper one is broad; cell-streaks of the forewing distinct, the subapical area of the cell always shaded with 

 brown; the pale patches before the margin of the hindwing, on the under surface, more distinct than in 

 acritus. W^e.st Colombia and Ecuador to Bolivia. 



P. Columbus Koll. (=r hippodamus Fldr., burtoni Beak.) (16c). Very nearly allied to serville; the columbus.
