not much longer than the femora and the o^ have '2 hair-tofls. The species of the genus TitJiorrti liave short 

 broad wings with bhxck ground-colour. They are not at all like the other Ithomiids and recall the Dnnai.s- 

 species in the shape of the wings. They inhabit the north-west of South America to Panama. 



T. humboldti Lutr. (= flavomaculata Stgr.) (32a). A stately, velvety black Initterfly with yellow humhohlli 

 macular liand across both wings and yellow sul)apical spots on the forewing. On the under surface tlie fore- 

 wing has also yellowish stripes at the base and behind them a double spot. The Ihndwing has b(-neatli at the 

 base a yellowish streak and a further oblique band, as well as a brown spot outside the cell. In addition 

 both wings bear a row of white submarginal spots. From the t'auca Valley in Colombia, according to Latkeille 

 also from the Amazons ( •'). — As albomaculata HscJi. I have designated a form in which the spots on the forewing 

 are white. It appears to be commoner than the typical Jiuniboldti, and occui's on the eastern slojjes of Ecuador 

 and Colombia at elevations of ca. 1500 m.

T. cassandina Smka, from Ecuador, is a. smaller species, similar to alhoindcnhttd. The yellow spots cassaiidina. 

 of the hindwing are very small, on the contrary the brown spot on the under surface at the end of the cell is 

 very large. The submarginal spots on the underside are bluish white. The species recalls Hcliconiiis eassandra Fldr. 



T. bomplandi Guer. (32 b) is the commonest species of the genus. On the upperside the forewing has bonii'huidi. 

 besides the spots of albomaculata also the white streak and double spot of the underside. The hindwing is marked 

 as in favonii (figured on the upper surface), only proportionately larger. Comes mostly from Colombia, but 

 also from Bolivia. — descandollesi Sigr.. from the Cauca Valley in Colombia, is a form in which all the nor- 

 mally white spots of the upper surface are yellow. — latreillei ,S7(//-.. likewise from the Cauca \'alley, has the hdrcilb'i. 

 yellow spots like descandollesi, but the band of the hindwing is much broader and behind it follows a further 

 yellow macular band almost as in liwmholdti. On the under surface the Ijrown spot at the discocellular is much 

 smaller, but continued by 2 smaller spots. 



T. regalis Sticli. {— dagua Slyr. i. I.) is very similar above to bomplavdi, except that the white rcij(di^. 

 spots at the discocellular of the forewing are perceptibly larger. Beneath on tlie conti'ary the ground-colour 

 is principally brownish except on the disc of the forewing and the bordering of the white spots and dots. The 

 species comes from the Rio Dagua in Colombia. 



T. pavonii Btlr. (32 b) is the smallest species of the genus and above similar to bomiilandi. Streak and paidtiii. 

 double spot at the base of the forewing are yellowish. On the under surface some of the spots at the end of 

 the cell of the forewing are also yellowish and on the hindwing there are 2 complete rows of brown spots between 

 the rows of white dots and the oblique band. Butler describes the species from Panama and compares it with 

 the similar Heliconius feruvianus. But it occurs also in western Ecuador and Peru, as well as in Boli\ia. In 

 Ecuador it flies with the confusingly similar Heliconius aithis in the same localities. 



T. tamasea Hew., from Colombia, has some similarity to descandollesi, but the yellow spots at the base lamaKca. 

 and at the end of the cell of the forewing are absent; moreover the yellow band of the hindwing is narrower 

 and abbreviated. On the under surface both wings have whitish marginal dots. The forewing has a brownish 

 band near the median and 2 brownish spots near the apex. The hindwing has further 2 brownish bands at 

 the base and in the disc before the yellow spots. In an aberration from the same locality the band of the 

 hindwing is reduced to 2 spots, of which the distal one is partly brownish. On the under surface almost the 

 whole disc of both wings is brownish. — A further form, which I call lugubris jorvi. nov., has the upper surface lugrdiris. 

 of the wings unicolorous black-brown, only the minute white double dots in the distal margin of both wings 

 remain. On the under surface there are also a brown subapical band on the forewing and sulnnarginal liand on 

 the hindwing. The form comes likewise from Colombia.

The distinctive characters of this genus have already been given under Titliorca. It may further be 

 divided into 2 large groups, namely: a) Wings short and broad, patagia black-brown, b) Wings elongate, 

 patagia red-brown. The species of the first group recall Danais and Tithorea by their wing-contour; those of 

 the 2. group have pronounced ,,Li/t'orea-habitus". The species are distributed over the whole Neotropical region 

 from Mexico to South Brazil. They are mcjstly found singly at the edges of the woods or at flowering shrubs 

 with the corresponding species of Melinaea. MrcJianitis and ('eratvnin.
