42 PAPILIO. By Dr. K. Jordan. 



broad, the margin of ilie hindwing between costa and i. radial entire!}' or aln^ost entirely black. The 

 dilated part of the dorsal edge of the harpe distally with triangular tooth, ventral process denticulate from 

 the ])ase to the tip. Very similar to archesi/aiis, forewing at the base broader green, the black bands 

 somewhat thinner, band 1 not extending beyond the 2. submedian, band 4 rarely reaching to the 2. cell- 

 fold : hindwing less strongly dentate than in an-hrsUmis, the subbasal band of the forewing beneath narrower. 

 Wings of the"? slightly yellowish, especially the anal region of the hindwing. Costa Rica, Panama and the 



arcliesilaiis. islands off the West coast of Panama. — archesilaus Fldr. (= rubrocinctus Eimer partim) (15a). On the 

 whole considerably larger than protpsiluus, hindwing more strongly dentate, the apex of tiie cell of the hind- 



proti'si/aits. wing beneath more or less edged with red. Colombia, West Ecuador and North Venezuela. — protesilaus L. 

 (15 c). Bands 1 and 2 of the hindwing usually extend beyond the 2. sulnnedian, band 4 mostly goes beyond 

 the middle of the cell and sometimes reaches to its hinder margin, the transparent submarginal band has 

 at least in the costal third brownish scales; hindwing more strongly dentate than in glaucolaus Inims. Frons 

 in specimens from the Andes often entirely brownish black. Dorsal edge of the harpe dilated into a tooth, 

 which is sometimes absent in specimens from the Andes. Orinoco, Guiana, the Amazon from Pari upwards, 



nigiicoinis. and Eastern slopes of the Andes of Ecuador, Peru and Bolivia. — nigricornis .sYr/r. ( = leilus Swains, partim). 

 Antenna usually black; frons brownish black, not white at the sides. Dorsal edge of the harpe with large 

 tooth. East Paraguay and Brazil. 

 helios. P. helios R. (& J. (15b). Antenna and frons brownish jilack as in niiirivoynh. Wings brownish; fore 



wing transparent; hindwing more sharply dentate tlian in nigricornis, the black postdiscal band straight, not 

 interrupted posteriorly as in the protesilaus forms, the marginal and submarginal l^ands yellowish. Under 

 surface more yellow than upper; the red line of the hindwing distally edged with white. Dorsal edge of 

 the harpe not dilated into a large tooth, the apex of the harpe pointed, ventral process not denticulate. — 

 Brazil, only knoAvn to us from Parana. 



orihosilaus. P. orthosilaus Wejiiii. (16c). Antenna yellow-brown, not black. Frons yellowish white at the sides. 



Forewing transparent; hindwing strongly dentate, above also with a median band, the postdiscal band and 

 the black margin merged together into a broad marginal band, the yellowish marginal and suljmarginal 

 lunules smaller. — Paraguay and Goyaz in Brazil ; rare , to our knowledge only 3 cfcf at present known. 

 earis. P. earis R. & J. (16a). Antenna dark yellowish brown. Frons yellowish at the sides. Wings slightly 



yellowish, beneath slightly reddish; bands narrow, 4. band of the forewing reduced to a small spot, 6. band 

 close to the lower angle of the cell; the yellowish marginal and submarginal spots of the hintlwing narrow, 

 above and beneath smaller than in the name-typical protesilmis ; hindwing beneath with long arrow-shaped 

 patch before the abdominal margin, this patch reduced in protesilaus. Dorsal margin of the harpe slightly 

 widened, ventral process non-dentate, not extending to the lower edge of the clasper, central process short, 

 broad, spatulate, strongly dentate. ? not known. — Eastern Ecuador, ])robably more widely distributed. 

 steiiodesmiis. P. stcnodcsmus E. d' .1. (15b). Antenna black. Frons laterally white. Forewing distally transjiarent. 



the bands thin, interspace between band I and 2 half as wide again as that between bands 2 and 8; hind- 

 wing longer than in protcsihnis and trh'siUins, usually slightly yellowish, strongly dentate, median band of 

 the under surface somewhat curved, placed nearer to the extremity of the cell than in prutesi/uHs and fricsiluus. 

 Dorsal edge of the har])e )iot dilated. For lai'va and jnipa see p. 40. — Paraguay; Brazil, from Petropolis 

 to Blumenau; a common species, usually mistaken for ])rolrsi/tiiis and trlfsi/aiis. 



P. telesilaus. Body and wings 3'ellowish; antenna brownish yellow, frons white at the sides; sub- 

 marginal and marginal spots of the hindwing yellow. Dorsal edge of the harpe slightly or not at all dilated: 

 central process either simjjle ov ventrally denticulate at the base. Scent-scales shorter and broader than in 

 the other species of this group, with the exce])tion of agi'siluus. Larva not known with certainty. Panama 

 to South Brazil; the cfcf very common, often resting together with jimti'sihrns, agesi/diis, g/aiico/ims, etc., on 

 doliiis. damp sand or mud. — dolius L'. & J. Band 1 of the forewing not prolonged to the hindmargin; margin 

 of the hindwing more extended white than in the next subspecies; subbasal band of the underside of the 

 hindwing. not entering the basal cell. Dorsal edge of the harpe only very feebly dentate, scarcely at all 

 dilated, central process not denticulate ventrally at the base. Panama and West coast of (jolombia. — 

 tetesilaiis. \t\Qs\\2MS Fldr. (16a). Band 1 of the forewing continued along the 3. submedian; subbasal band of the 

 hindwing beneath entering the jjasal cell. Dorsal edge of the harpe dilated, denticulate, central process 

 with dentate ridge ventrally at the base. Central Colombia to Guiana and Paia, distributed southwards to 

 BoUvia, Paraguay and Rio Grande do Sul. 



Thyastes-Group. 



In the species of the densely scaled ///yf/.s7<>.s-oroui) the liiiidwing has on the under surface a red or brown- 

 yellow band , which runs about parallel with the outei- margin and begins at the costal margin beyond the middle. 

 In all the sj)eoies the 1. subcostal anastomoses with the costa, which does not occur in the preceding groups. 



P. marchandi. Hindwing beneath with brown-yellow discal band. Markings of the upper surface 

 yellow, both wings with yellow discal area and submarginal spots, the area of the forewing continued towards
