ITHOMIA. By R. Haensch. 141 



I. phanessa H.-Schdff. and alienassa Hsch. (37 d), from Colombia, have transparent yellowish wings, alienafsa 

 ■phanessa has broad, yellow-brown submarginal distal border to the hindwing and in the cell of the forewing an 

 isolated, triangular spot. In alienassa the distal margin of the hindwing is black-brown with red-brown macular 

 streak, and across the middle of the cell of the forewing there is a dark half-band. 



I. cleora Hew. (= chimborazana Beak., spruceana Bates) (37 C(^, $), from western Ecuador, was cleora. 

 formerly often confused with the preceding two. It may, however, be recognised at once by the long, pointed, 

 black spot in the cell of the hindwing. On the other hand the red-brown colouring varies very much. There are ,^(^ 

 in which this is almost entirely absent and $$ in which the basal half of the forewing and of the hindwing are 

 almost entirely red-brown. 



I. epona Hew. (37 d) has transparent smoke-brown wings with darker margins; half-band across the epona. 

 end of the cell of the forewing, as well as median spot in the cell. In the $ the distal margin of the hindwing 

 is broader, -nith whitish dots. The species flies in the mountains of eastern Ecuador at elevations of 1500 — 3000 

 metres together with the similar Dismenitis heivitsoni. 



I. xenos Bates (37 d) is a similar species with narrower wings, from Costa Eica. The forewing has slightly xenos. 

 yellowish patch and a dark half-band through the middle of the cell. The distal border of the hindwing in the ^ 

 is very narrow. In the rare $ the margins and patches are broader, at the median of the forewing and on the 

 hindwing proximally red-brown. 



I. ulla Hew. (= radata Weym.) (37 e) is another species from Colombia, but with peculiar neuration. ulla. 

 BoiSDfVAL erected for it the genus Tagyris. The forewing is very broad; the discocellulars close the cell in arc- 

 shape and form an acute angle with the very small third section of the median vein. The scent-spot of the hindwing 

 terminates with a neck at the end of the cell, as in Hypoleria-species. ulla has behind the band at the end of the 

 cell of the fore'tting a yellowish patch and a yellow-brown subcostal. In the $ the margins are broader and 

 there is also a half-band across the end of the cell of the hindwing. — The same neuration is found in dimidiata Stgr., dimidiata. 

 from the Cauca Valley and eastern Ecuador. This species has slightly smoke-brown wings with brown margins, 

 but without half-band across the end of the cell and without yellow patch. 



Another similar species is I. mira Stgr., from the Amazons, but with different neuration, red-brown mira. 

 subcostal and small spot at the end of the cell of the forewing. 



I, peruana Sale. (= abendrothi Hpfr.) (37 d) has transparent, yellowish wings with broad, black margins iperuana. 

 and half-bands across the end of the cell and through the cell of the forewing. It occurs at Chanchamayo in 

 eastern Peru. 



I. linda Hew. (37 d), from Ecuador, has exactly the appearance of Ceratinia antea and Napeogenes glycera, linda. 

 with which it also flies in company. It is somewhat smaller and the cj is conspicuous by the broad costal margin 

 of the hindwing. — theuda Hew., likewise from Ecuador, is a very similar species with somewhat yellowish wings theuda. 

 and black antenna, whilst in true linda the club of the antenna is yellowish. 



I. nigrimargo Btlr., from Ecuador, approximates to the preceding, but has a red-brown spot at the anal nigrimargo. 

 angle of the hindwing and is hence very similar to Ceratinia adelinda and other forms. 



I. lagusa Heiv., from Colombia, and I. hymettia Stgr. (37 d), from the Cauca Valley, strongly recall ]^f^''^^fl 

 certain N a peogenes-n'pecies. The neuration of the (^(J almost exactly agrees with that of this genus in the long 

 cell of the hindwing with the lower discocellular only weakly curved proximad. The forms may, however, be 

 recognized with certainty by the scent-spot of the ^^ and the recurrent cell-vein in the $. In lagusa ^ the basal 

 third of the forewing is black-brown with oblong yellow-brown spot and broad half-band at the end of the cell. 

 In the $ the dark margins at the base are narrower, at the apex and at the distal margin of the hindwing on the 

 contrary broader, hymettia has colourless wings, broad inner margin to the forewing and yellow-brown streak 

 at the median; further a half-band at the end of the cell and in the ^ narrow, in the $ broad, dark margins 

 to both wings. 



The beautiful I. ellara Hew. (37 e), from Bolivia, has colourless wings with broad black margins and ellara. 

 patches at the end of the cell and in the cell of the forewing, and large, transparent marginal spots. On the 

 under surface the markings are for the most part brown-red. The antenna has a yellow-brown club. — The very 

 similar eleotiora Hsch., from the border of Peru and Bolivia, has narrower distal margins, without the transparent eleonora. 

 marginal spots, but at the costal margin of the forewing a suggestion of a subapical band, and also black antenna. — 

 In an aberration, which I call ab. beata ab. nov., there is a large, yellow-brown spot in the distal margin at the beaia. 

 inner angle of the hindwing above. — avella Hew. ($ = cesleria Hew.) (37 e), from Colombia, is a similar, smaller avella. 

 species with red-brown subcostal to the forewing and without the dark colouring in the cell of the hindwing. The cj 

 has considerably narrower margins and patches than the figured $. 



The ^ of I. hyala Hew. (37 e) is conspicuous by the broad forewing and small hindwing. The wings are hyala. 

 slightly smoke-brown with dark margins and 2 half-bands through the cell and at its end. The base of the hind- 

 wing is yellow beneath. In the $ the wings have the usual shape, somewhat as in diasia.
