40 PAPILIO. By Dr. K. Joeban. 



the black median band only extending to the cell; the latter less pointed than in philolans. The scent-scales 

 of the cf longer. The ? not known. — San Pedro Sula. Honduras (in coll. Chaeles Oberthur). Our figure 

 is too small. 

 arcesilans. P. arccsilaus Luras (= anaxilaus Fldr.) (14 d). Antenna black. Forewing with 6 greenish bands 



and a row of submarginal spots, the 6. band short, separated from the discal area. Scent-scales of the cf 

 long. — North Venezuela and Colombia. 



P. epidaus. Antenna black; wings white, semitransparent, distally almost glassy. The 2. black 

 band of the forewing extends to the hindmargin beyond the middle and the discocellular band is continued 

 to the 2. median or to the posterior angle of the wing. Larva not known. Mexico to Honduras. — 



^~->«s\ epidaus. epidaus Doubl. (15 c). The 2. black band of the forewing not more than half as broad a^ the light inter- 

 space between the 2. and 3. bands, generallj' narrower, the 5. band not extending far beyond the 2. median, 

 not reaching to the marginal band ; the posterior part of the median band, on the underside, thin or merely 

 indicated. From East Mexico to Nicaragua, from whence specimens of this form have recentlj' come. — 

 tepicus. tepicus B. & J. 1. and 2. bands of the forewing broader than in the preceding form, 5. band posteriorly 

 joined to the marginal band ; hindwing longer and the costal margin shorter than in the other forms. West 



-~^ fenochionis. Mexico: province of Jalisco. — fenochionis Godm. & Salv. 5. band of the forewing prolonged to the hinder 

 angle, hindwing much more extended black than in the previous subspecies. South- Western Mexico: Oaxaca, 

 Guerrero. 



. bellerophon. P. bcllerophon Balm. {■= coresilaus Godt., swainsonius Swains.) (15 a). The only Papilio in which 



the 1. subcostal of the forewing is absent. Forewing semitransparent, with 4 black bands. ? similar to 

 the (f, with somewhat broader hmdwing. Scent-organ of the cf woolly. — Brazil : Minas Geraes , Parana, 

 Santa Catarina, rather rare. 



Protesilaus-Group. 



The species of the following protesilaus - group with the exception of agesilaits are hard to diiFerentiate 

 without the assistance of their genitalia. The red line on the under surface of the hindwing is only edged with 

 black at one side. These white, black-banded butterflies include some of the commonest Papilios of South America; 

 but this applies only to the d'cf, the $? on the contrary being very rare in collections. The cfcf often rest in 

 dense clusters on damp sand or mud. The larva of only one of the species (P. stenodesimts) is known with certainty; 

 it is green, dorsallj^ spotted with black and with transverse bands, sometimes the black markings are absent until 

 a transverse line on the prothorax. The dorsal horn of the pupa is very long. Tlie butterflies are tropical. 



P. agesilaus. Easy to recognise by the red line of the hindwing being edged with black distally. 

 Distributed from Mexico to Bolivia and Goyaz in Brazil, not j^et known from Nicaragua and Costa Rica, 

 fortis. where, however, the insect certainly occurs. — fortis B. & J. fi'om South-West Mexico: GueiTero, Atoyac, 

 Oaxaca. The black bands broad, 1. and 2. bands of the forewing about -/s as broad as the interspace, 

 both contmued to the hindmargin , or the 2. band at least extending bej'ond the 2. submedian ; the white 

 submarginal bajid not broader than the black postdiscal band, the latter not divided longitudinalh' bj^ a 

 pale line; abdominal margin of the hindwing black, the two red anal spots surrounded with black. — 

 \-^ neosilaus. neosilaus Hopff. The black bands narrower than in fortis, the 1. and 2. bands of the forewing at most 

 half as l)road as the white interspace, the transparent submarginal band broader than the black postdiscal 

 band; abdominal margin of the hindwing partly white, the red anal spots anteriorly broadly edged with 

 white, much less broadly surrounded with black than in fortis. East Mexico, Guatemala, British Honduras, 

 , eimeri. Honduras. — eimeri B. & J. The transparent submarginal band of the forewing between the 4. and 5. 

 subcostal at most as broad as the black postdiscal band which is placed at its proximal side. West Colombia, 

 ng^f?5//o(;s. upper Cauca Valley and Panama. — agesilaus Guir. (= conon Hew., septemlineatus Eimer) (15c). Post- 

 discal band of the upperside of the forewing without light median line, narrower than the costal half of 

 the transparent submarginal band; subbasal band of the upper surface of the hindwing only represented 

 by a thin streak placed on the 2. median. Verj^ variable in size. Central and East Colombia, North 

 aiitosilaiis. Venezuela. — autosilaus Bates. Postdiscal band of the forewing divided longitudinally by a pale streak, 

 subbasal band of the hindwing present on the upperside. Orinoco, Guiana, the Amazon, Go5'az, the eastern 

 slopes of the Andes from Ecuador to BoUvia. as well as Pai-aguay. not yet known from South-East Brazil : 

 like the preceding subspecies very common. 



P. glaucolaus. In order to differentiate this and the following species with certainty, it is necessary 

 to compare specimens from the same districts, and at times to take the sexual organs into consideration. 

 In glaucolaus the black jjostdiscal band of the forewing is wideh" separated from the lower angle of the cell, 

 or the teeth of the hindwing are very obtuse and the posterior submarginal spots suffused with brown. 

 Scent-scales of the cf as long as in protesilaus-. the harpe has at the dorsal edge a ver}- long tooth and the 

 central and ventral processes are short, the latter not reaching to the ventral edge of the clasper. From 

 Panama to Guiana, Upper Amazon, southwards to Matto Grosso, not yet known to us from South-East Peru, 

 Bolivia, Paraguay, Brazil proper and the Lower Amazon. Onty cfcf in collections. A common species. 

 glaucolaus. Larva not known. — glaucolaus Bates (15 a). Greenish, bands 1 and 2 of the forewing not extended beyond
