ITHOMIA. B^J B. Haensch. 



lular in the hindwing. Superficially they resembles some species of Callithomia, Ithomia and Calloleria. 

 area of distribution is confined to north-west South America and Panama. 



Their 



agrippina. E. agrippina Hew. (= eallipero Bates, $ balboa Bates) is the same size as the figured alfho. Base of the 



forewing and the hindwing red-brown, the latter with broad, dark margin. Forewing with 2 yellow oblique 

 bands across the end of the cell and at the apex, as well as a spot between these at the distal margin. The rest 

 of the apical half is blackish, also a spot in the cell. The species flies in Colombia and Panama. — In a form 

 fumantis. from Colombia, which I call fumantis form, nov., the dark margin of the hindwing is proximally spot-like, irregular, 

 widened almost to the cell. The ground-colour is darker. The white marginal spots of the under surface are 

 very large. »*■ 



alpho. E. alpho Fldr. (37 b) has semitransparent wings with diffuse, yelloAv-brown colouring and similar markings 



to agrippina. — In a form which like alpho comes from Venezuela, there is a median band in the hindwing which 

 nikita. is composed of 3 angular, dark spots. I call this form nikita form. nov. 



22. Genus: Ithomia Hbn. 



Formerly most of the small, transparent forms of the family were included under this name. At the 

 present time we understand by it a smaller, but still numerous group whose best distinguishing characters are 

 the large, oval scent-spot of the ,^i^ and the long cell of the hindwing with angled lower discocellular. Very striking 

 in .many ^^, e. g. hyala (37 c), are the large broad forewing and small hindwing; in the latter the costal margin 

 is strongly arched anteriorly by the scent-spot. In the $ the cell of the hindwing is cut off rather straight, a vein 

 extending into the cell. The variety of colour and form in this genus is very great; it contains both gay-coloured 

 sj)ecies which closely resemble certain Ceratvnia and N apeogenes and also inconspicuous, colourless forms, which 

 are mimicked by species in the following genera. The area of distribution of the genus is correspondingly also 

 a very large one, including the whole of the Neotropical Eegion. North- Western South America, however, produces 

 the most representatives of this, as also of other genera. 



heraldica. I. heraldica Bates (37 b), from Costa Eica, has black-brown forewing with red-brown base, 3 yellowish 



plardnota. macular oblique bands and whitish subapical dots. The hindwing is red-brown with dark distal margin. — pla- 



ginota Btlr. & Druce (37 b) is a similar, larger and more brightly coloured form from the same district. In it 



the yellow subapical and marginal dots are more strongly developed; but of the oblique bands only the distal 



one and the half of the median band in the cell are yellow. The base of the forewing is more broadly red-brown. 



celemia. In I. celemia Hew. (37 c), from Colombia, the oblique bands are broken up into smaller spots. The 



lurida. distal margin of the hindwing is broader and in it are placed yellow dots. — lurida Hsch. is a local form of the 



preceding from the Cauca Valley in Colombia with very large, band-like spots in the disc of the forewing and 



candescens. large dots in the apex of the forewing and the distal margin of the hindwing. — candescens Hsch. is a form of 



splendcns. celemia from Colombia and Venezuela with white instead of yellow spots and dots. — splendens Hsch. is coloured 



like candescens, but with very large, white spots and dots, corresponding to lurida. 



iphianassa. I. iphianassa Dbl. & Hew. is a somewhat smaller, very variable species, of which anaphissa (37 c), 



panamensis (37 c) and others are merely local forms, iphianassa, from Venezuela, best represents the Lycorea- 

 habitus and the pattern of the other forms can be derived from it. The scheme of markings is the same as in 

 anaphissa, but the base of the forewing and the hindwing yellow-brown. The latter with undulate distal margin 

 and black-brown longitudinal band, bent in hook-shape at the apex. The basal area, especially in the ^J, is 

 lighter yellowish, semitransparent, with dark dots at the end of the cell. The forewing has an indistinct, yellow- 

 brown median band and a yellow subapical band ; between them is placed at the distal margin a roundish, yellowish 

 spot. The rest of the apex and 2 spots in the basal part are black-brown; apex with 2 or more whitish marginal 

 anaphissa. dots. — In anaphissa H.-Schdff. (= pepita Oberih.) (37 c), from Colombia, the distal margin of the hindwing 

 and the median band are united into a broad, black distal margin; also the apical half of the forewing is more 

 panamensis. In'oadly black with larger, white marginal dots. — panamensis Bates (37 c), from Panama, has a much broader, dark 

 distal margin to the hindwing, which reaches to the end of the cell. The yellow subapical band of the forewing 

 lycasle. is entirely suppressed except for 4 very small spots. This form strongly recalls Mechanitis macrinus. — lycaste F. 

 negrita. is a very similar form from Kansas in North America with still more stronglj^ black markings. — negrita Reali., 

 from California, is another allied form, in which the black median spot of the forewing is enlarged, half of it 

 houcardi. being on the hindwing. — In boucardi Druce, from Panama, the yellow median band of the forewing is absent. 

 The whole basal half is j^ellow-brown with large, black median spot. The broad distal margin of the hindwing 

 pumensis. and a spot at the end of the cell are black. — As pumensis Reaklrt designates a form of iphianassa, from Venezuela, 

 with larger black spots and red-brown basal part, without the yeUow median band. The yellowish spot at the 

 distal margin is very small. The forewing has 3 white dots at the distal margin.
