38 PAPILIO. By Dr. K. Jordan. 



discal spots and a rather large cell-spot on the forewmg; the apical half or two-thirds of the cell of the 



hindwing red, as are also 6 large discal spots, abdominal mai'gin at least partly red. Venezuela. — 



metageiies. mctagencs R. & J. cf : forewing usually with a band reaching from the hindmargin to beyond the 3 radial, 



merely indicated on the underside; hindwing with 4 or 5 spots placed separate from the cell. ?: forewing 



with the long white discal band which is also peculiar to the Aristolochia-Papilios P. anchises thelios and 



P. acjlaope, this band consists of two large spots with a smaller one placed before and behind them; hind- 



gayi. wing with 6 red spots, 3 of which are contiguous to the cell. Para. — gayi Lucas. cT and ? very variable : 



anargus. 3 principal forms: f. anargus R. <& J. (13d), forewing without band or spots; f. cyamon Gray {= charoba 



cyamon. Kifhi/) dSd), <:? with narrow band on the forewing, on the whole somewhat more distally placed than in 



the o^ of evagoras, ? with narrow, indistinct band on the forewing, with cell-spot on the hindwing, the spots 



on the hindwing sometimes j'ellowish white; in f. gayi Luc. (=r aristagoras Fldr.; arianus Stand.) the cf has 



on the forewing a more or less square hindmarginal spot, whilst the ? has 1 or 2 lai'ge discal spots, usually 



also a small third spot and often a cell-spot in addition. These different forms are not separated geograph- 



to/rira, ically. Distributed from Colombia to Bolivia and the Amazon downwards to Manaos. — leuctra R. & J. cf: 



forewing with a pure white area, of almost even width, reaching from the hindmargin to the 1. median, 



above about 6 mm. bi'oad and on the underside only a trifle narrower: hindwing with 6 long red discal 



spots, the 3 middle ones contiguous to the cell. Goyaz, Brazil. 



Uus. P. ilus F. (=7 hostilius Fldr.; guaco Stgr. (14a). cf$: under surface without red basal spots on the 



forewing, with 4 red basal spots on the hindwing. Forewing with or without a patch in the extremity of 



the cell, with 2 or 3 white spots on the disc, the posterior one, placed behind the 3. median, the largest. 



North Venezuela, Northern Colombia, Panama; rare in collections. 



P. branchus Doubl. Head and breast with red dots, a spot on the forecoxa white. Wings opaque ; 



forewing with or without white spots; hindwing with broad red discal band. Under surface without red 



branchus. basal spots on the forewing, with 4 such spots on the hindwing. Sexes similar. In the f. branchus Doubl- 



belephantes. (14 b) the forewing has a variable white central area, which is absent from f. belephantes Godm. & Salv. ~ 



Mexico to Costa Rica. 



^^^ belesis. P. belesis Bates (14 b). Similar to the preceding species, hindwing with a band of 6 to 7 red spots, 



parallel to the margin, placed nearer to the margin than to the cell. Forewing in f. belesis Bates without 



hephaestion. white spot, in f. hephaestion Fldr. with a spot between the 2. and 3. radial and sometimes the indication 



of a second spot behind the 3. radial. — Mexico to Nicaragua. 



P. thymbraeus. The small spots on head and breast grey-yellow, often slightlj' reddish. Upperside 

 of the wings slightlj' but yet distinctly metallic blue or green; forewing without markings, but with white 

 fringes; hindwing with a slender tail and 1 or 2 rows of spots between ceU and margin. Under surface 

 with I'ed costal basal spot on the forewing and 4 basal spots on the hindwing. Larva on Chirimoj'a; the 

 thorax dotted with blue and yellow; striped with white and black from the 4. segment backwards, the 

 white stripes with small blue and yellow spots, the sides blue, from the 5. segment dotted with yellow. 

 Pupa green, as in the alhed species, appearing constricted at the base of the abdomen. The butterfly flies 

 in the open country the whole 3'ear through, and is rather common at a height of 500 to 1560 m. — 

 ' tliynibraeiis. i\[ymhr?LtMS hoisd. (14 b) is distril)uted from East Mexico to Honduras. The hindwing in c/ and ? has 

 aconophos. 2 rows of red spots. — In aconophos Grai/ the hindwing has only one row of red spots, the discal row 

 is absent. Central and West Mexico. 



P. lysithous. A polychromatic species. The different individual forms with one exception were 



originally described as species and have been regarded as such until recentty. The forms are connected 



with one another by intergradations ; moreover, the specific identity of 3 of the varieties (pomponius, rnrik, 



lysithous) has been proved b}^ breeding. Underside of the forewing with 2 red basal spots, hindwing 



with 3; all the forms with a tail. Larva on Anona, resting by day on the upperside of a leaf at the 



middle vein, on the lower )3ranclies and root-shoots, near Petropolis all the year round, except in June and 



July (middle of the dry season) ; black with yellow longitudinal stripes and white-yellow saddle-spot. The 



pupa as in the allied species green with yellow lateral streak. Brazil and Eastern Paraguay. The principal 



\ platydesma. forms, which do not everywhere occur together, are the following: f. platydesma R. & J. (= harrisianus 



auct^ (1-tb), the white band of the forewing very broad, continued over the cell to the costal margin; 



linrn'sianus. f. harrisianus Sivains. (^Claudius Boisd.; athous Fldr.), the white band of the forewing broad posteriorly, 



strongly narrowed anteriorlj-, not entering the cell, the part from the lower angle of the cell to the costal 



margin narrow or absent, as in the preceding form the posterior submarginal spots of the hind^\^ng large; 



oedipus. f. Oedipus Fldr. (= sebastianus Oberth.) (14a), forewing -with double spot from the 1. median backwards, 



lysithous. hindwing without white band, the 4 posterior submarginal spots large; f. lysitiiOUS Hbn. (14a), band of the 



bmii- forewing narrow, often abbreviated (ab. brevifasciatus Weyvi.), hindwing with small submarginal spots, the 



<\tendatus ^^^^^^ band usually only extending to the 1. median, sometimes longer and more distal (ab. extendatus 



' rurik. Weym); i. rurik Eschsch. (^= rurikia id. in tab., laius Boisd.). band of the forewing abbreviated, hindwing 



s pomponius. without white band, the 4 posteiior submarginal spots rather large: f. pomponius Hopff'., band of the fore-
