 the costa on the forewing, beginning at the co.stnl margin of the forewing distally to the cell and ending 

 before the abdominal margin of the hindwing: hmdwing triangnlar. with long tail. On the nnderside the 

 hindwing has 4 I'ed basal spots, two of tliese placed at the costal nmrgin, in addifi(ni a red streak before

In the iiiajri'n.iis-grou.Y) there is on the underside of the hindwinij' a red line running from the costal margin 

 to the anal angle, which at least at the costal margin is edged with black at lioth sides. The species have bands 

 on the wings, and the triangular hindwing is tailed. The 1. suljcostal of the forewing is free: in one s])ecies 

 (bcllerophon) it is entirely absent. 



P. marcellus Cr. (= ajax (incf.) (I4c). The cmnnion Asimimt Swallowtail of North America. Anteinui 

 brown-yellow; tibiae and tarsi gi-een : forewing with S greenish wdn'te bands, the green cohnii' in the mem- 

 brane: the red line of the hindwing beneath margined with wliite ])ro\imally. Scent-scales of the cf long. 

 The larva with 6 fine black transverse lines on each segment, the lines usnally partly contiguous. The 

 frontal prominences of the pupa divergent, the thoracic horn vertical, the lateral carina continued to the 

 cremaster, not interrupted. Foodplants: Asimina, especially A. triloba, also Ericaceae and Lauraceae. This 

 species is one of the classical examples of seasonally varial)le buttertlies. In the specimens wdiich hibernate 

 as pupa once or twice the hairs of the frons are long. A\liilst tliey are short in the buttertlies emerging 

 from non-hibernated pupae. The principal forms are: forma hib. marcellus (V. (^^ walshi AVZ/r.), the spring moiciilus.

 large, the black bands broad. — P. marcellus occurs from Southern Canada to Florida and Texas and west- 

 ward into the prairie districts of the Mississippi Plain. Very common where pawpaw trees are found. The 

 tlight of the summer brood is more elegant than that of the spring specimens. The butterfly often travels 

 northwards in considerable numbers, flying swiftly neai' the ground. Indeed in the northern districts where 

 it occurs it is only an immigrant, not a permanent inhabitant. 



P. marcelliiius Donhl. (= sinon F. non Foda) (14c). Forewing with pale green bands and a row niarcrlliinis. 

 of subniarginal spots ; hind^\'ing with black submedian band extending to the black distal margin ; the red 

 line on the under surface of the hindwing broad, reaching to the brown margin. Scent-scales of the cf 

 long. — .lamaica. 



P. celadon Lacaa (= sinon (rotlf. non Poda) (14 c). Similar to the preceding species, but on I he celadon. 

 forewing the pale green discai band is continiujus with the 3. and 4. pale green cell-bands, not with tiie 

 4. and 5. : the red line on the nnderside of the hindwing thin, shorfei- than in mKreellinnn. The anal lergite 

 of the o"" is not divided, as the lateral prongs are absent. — Cuba; perhaps also in Florida. 



P. zonaria Bllr. (^ sinon F. non Poda) (14c). The pale bands narrow; the 4. and 5. pale green --ohw/i;. 

 cell-bands of the forewing continuous with the discai band, narrow, separated from one another. — Haiti.

 with black at both sides, undulate anteriorly. Scent-scales of the o"' short, broad, irregular, produced in a 

 number of filaments. The ? in 2 forms: ?-f. philolaus Boisd. similar to the cf. the underside paler; ?-f.

 scaled with black, the wings therefore black with slight tiaces of the bands. — Larva not known. The 

 butterfly I'ommon from Mexico to Nicaragua, in low situations, often resting in crowds on the sand at the 

 edge of I'ivers.
