42 PAPILIO. By Dr. K. Jordan. 



broad, the margin of the hindwing between costa and 1. radial entirely or alrjost entirely black. The 

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

 the ]3ase to the tip. Ver}' similar to archesilaun , forewing at the base broader green, the black bands 

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

 fold; hindwing less strongty dentate than in archesilaiis, the subbasal band of the forewing beneath narrower. 

 Wings of the ? sUghtly yellowish, especial!}- the anal region of the hindwing. Costa Rica, Panama and the 



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

 whole considerabh" larger than protesUaus, l;iindwing more strongh' dentate, the apex of the cell of the hind- 

 protesilaus. 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. submedian, band 4 mostly goes be3^ond 

 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 leucas. Frons 

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

 which is sometimes absent in specimens from the Andes. Ormoco, Guiana, the Amazon from Para upwards, 

 nigricornis. and Eastern slopes of the Andes of Ecuador, Peru and Bolivia. — nigricornis Sigy. (= leilus Siraiiis. partim). 

 Antenna usualh' black; frons bro\\mish black, not white at the sides. Dorsal edge of the hai'pe with large 

 tooth. East Paraguay' and Brazil. 

 helios. P. helios B. (S; J. (15b). Antenna and frons brownish black as in nigricornis. Wings brownish; fore 



^ving transparent; liindwing more sharpl}' dentate than in nigricornis, the black postdiscal band straight, not 

 interrupted posteriorly as in the protesilaus forms, the marginal and submarginal bands 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, onlj- known to us from Parana. 



i orthosilaus. P. orthosilaus Weyiii. (16 c). Antenna j'ellow-brown, not black. Frons yellowish white at the sides. 



Forewing transparent: hindwing stronglj- dentate, above also with a median band, the postdiscal band and 

 the black margin merged together into a broad marginal l^and, the yellowish marginal and submarginal 

 lunules smaller. — Paraguaj- and Gojaz in Brazil; rare, to our knowledge only 3 cfcf at present known. 



—^r-earis. P. earis R. & J. (16 a). Antenna dark j^eUowish brown. Frons j^ellowish at the sides. Wings slightly 



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

 close to the lower angle of the cell; the j'ellowish marginal and submarginal spots of the hindwing narrow, 

 above and beneath smaller tlian in the name-typical protesilaus ; hindwing beneath with long arrow-shaped 

 patch before the abdominal margin, this patch reduced in pirotesUaus. 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, probabty more widelj' distributed. 



stenodesmus. P. stenodesmus B. & J. (15 b). Antenna black. Frons lateraU}- white. Forewing distaUy transparent, 



the bands thin, interspace jjetween band 1 and 2 half as wide again as that between bands 2 and 3; hind- 

 wing longer than in pjrotesihnts and telesilaus, usuallj- slightly yellowish, stronglj' dentate, median band of 

 the under surface somewhat curved, placed nearer to the extremitj' of the cell than in protesilaus and telesilaus. 

 Dorsal edge of the harpe not dilated. For larva and pupa see p. 40. — Paraguay; BrazU, from Petropolis 

 to Blumenau; a common species, usuaUj' mistaken for protesilaus and telesilaus. 



P. telesilaus. Body and wings yellowish; antenna brownish j^eUow, frons white at the sides; sub- 

 marginal and marginal spots of the hindwing j-ellow. Dorsal edge of the harpe slightty or not at all dilated; 

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

 the other species of this group, with the exception of agesilaus. Larva not known with certaintj'. Panama 

 to South Brazil; the cfcf very common, often resting together with protesilaus, agesilaus, glaucolaus, etc., on 

 dolius. damp sand or mud. — dolius B. & J. Band 1 of the fore-wing 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 harjje onlj' very feebly dentate, scarcely at all 

 dilated, central process not denticulate ventraUy at the base. Panama and West coast of Colombia. — 

 telesilaus. telesilaus Fldr. (16a). Band 1 of the forewing continued along the 3. submedian; subbasal band of the 

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

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

 Bohvia, Paraguaj- and Rio Grande do Sul. 



Thyastes-Group. 



In the species of the densely scaled flit/asfes-grovLip the Mndwing has on the under surface a red or brown- 

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

 In all the species 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 -ndth yeUow discal area and submarginal spots, the area of the forewing continued towards
