with black median spot, but has on both wings continuous black marginal markings. The under surface is 

 somewhat more reddish yellow than in judd, the markings almost the same. 



Aj' ; godartiana. C. godartiana tiivains. (-= ovhis Bdr.) (26 b), from Haiti and Porto Rico, has half the upper surface 



5 of the forewmg white and the other half yellow; the white distal half has a narrow ^^ellow margin. The 



proximal part of the hindwing is reddish yellow, shading into greenish distally, a broad margin is white. 



The under surface of the forewing is in the anterior part j^ellowish with dark submarginal markings, in the 



posterior part whitish. The proximal part of the hindwing beneath is reddish white, the margins are greenish, 



the distal margin broadly so ; there are no markings except two white spots at the discocellular and a few 



small blackish submarginal markings. The ? has dingy reddish yellow upper surface with continuous black 



marginal markings, large black median spot and a small hook-shaped submarginal spot on the forewing. 



The hindwing has larger disconnected black marginal spots. The under surface is reddish yellow in the 



proximal part, in the distal part almost white with reddisli marginal markings, blackish submarginal markings, 



. large reddish median spot on the forewing and t\\o wliite, brownish-edged median spots on the hindwing. — 



t^ , neleis. neleis Bdv., from Cuba, Mexico and Guatemala, has the distal part of the upper surface less strikingly 



white and there are no markings on the under surface, which is yellowish on the proximal half and whitish 



on the distal half. The ? is above much lighter, more yellowish and with less black markings, the ground- 



t^ biitleri. colour of the under surface lighter. — butleri Scudd., from Mexico (Tehuantepec), is apparently only an 



aberrant female with light chamois-coloured upper surface and the markings somewhat more brown-black. — 



#^ hartonia. hartonia Bflr., from Jamaica, is in the cf above very similar to godartiana, only the greenish tinge is 



wanting; the under surface is quite similar to that of neleis, but has somewhat dark markings. The ? is 



similar to the neleis-'i, but has no continuous marginal markings on the forewing above. On the under surface 



the forewing is more yellowish, the hindwing more reddish, also less marked. 



<j^ 



orbis. C. orbis Poeij (26 a) from Haiti and Cuba, is ver}- peculiarly marked in the cf above. The orange- 



yellow colouring, which is spread over the whole upper surface in the ?, is onlj' present in the cf in a 

 large circular spot near the base. The distal half of the forewing is white, the rest of the wing yellow. 

 The hindwing is yellow, with broad white distal margin. The underside is reddish yellow with a 

 white, reddish bordered median spot on each wing, reddish marginal hne and led-brown submarginal 

 markings. The $ is entirely orange-yeUow above and has black marginal and submarginal spots and also 

 a square black median spot. The under surface is more strongly marked with red-brown than in the cf. 

 The pupa is comparatively slender, without anything striking in its form, the head-part produced into a 

 short point. Larva on Poincialia pulcherrima, green with yeUow venter, all the incisions light greenish 

 yellow. Pupa green, canoe-shaped, extremities pink and veins yellow (Boisduval). 



21. Genus: CJoneptei'yx Leac]). 



The few species of this genus would be better united under the generic name of Amijnthia Sirains., 

 since they not only differ from Gonepferijx-s])ecies of the Old World by their gigantic size, but also possess 

 structural characters which well separate them from Gonepteri/x. The fourth subcostal vein does not run 

 into the costal margin, as in true Gonepteryx, but into the much more produced apex. According to 

 E. Reuter the American species agree in the structure of the basal joint of the palpi, but differ in this 

 from the true Gonepteryx-s])ecies. The species which belong here cannot be mistaken on account of their 

 wing-contour, and possess a further common characteristic in that the subcostal of the hindwing appears 

 especialty developed on the under surface and is j^articularly conspicuous by its peculiar colouring. The 

 secondary male characters agree with CatopsiUa, but are even more developed, the greater part of the wing 

 above being covered with chalkA' scent-scales, whilst the scent-organ at the costal margin of the hind wing- 

 takes the form of a long, broad gland. One species is distributed from Paraguay, the other two have a 

 more restricted range. — Nothing appears to be yet known as to the earlier stages. 



u\ menippe. G. mcnippe Hbn. (= leachiana Godt.) (2^g) apparently occurs in the whole of tropical 



America, not even shunning the higher mountams. It surpasses the most conspicuous Indian Pierid, 

 Uebomoia glancippe, both in size and in beauty. The upper surface is light yellow, sometimes somewhat 

 darker, the apical third of the forewing is gorgeous orange-yellow, at the discocellular is placed a 

 large, square brown-red spot, before it sometimes also a smaller, but otherwise similar spot. The black- 

 broTvTi distal margin varies very much in ^idth; in most specimens it is as shown in our figure, not 

 * infrequentlj' it is reduced to marginal spots which are only connected by a marginal hne, occasionally 



^calypso, it is entirely absent: ab. calypso form. nov. The hindwing has only rarely blackish marginal spots. The 

 ground-colour of the under surface is likewise rather variable, from gi'eenish white to yellow, with more 

 or less sharp, light, somewhat opalescent markings; there are alwa3'S on both wings an oblong, much 

 interrupted reddish median spot and a more or less complete row of black submarginal dots; the sub-
