132 CEEATINIA. By B. Haensch. 



dionaea. C. dionaea Heiv. I only know in typical specimens from Central America (Honduras, Guatemala), on 



fraterna. the other hand in Venezuela a local form occurs which I designate fraterna foryn. nov. (35 a). In dionaea there 

 is proximally to the yellow oblique band a larger yellow spot which is joined to the red-brown basal part. In 

 fraterna there is instead only a small spot which is mostly confluent with the oblique band, but is proximally 

 edged with black. Moreover, in fraterna the yellow colouring is brownish and the distal-marginal dots are 

 smaller. In Mechanitis there are 2 corresponding forms: doryssus from Central America and veritahilis from 

 limpida. Venezuela. — limpida Hsch. is a peculiar form of fraterna, in which the yellow bands and spots are very broad 

 and transparent; a stripe at the costal margin of the hindwing is of the same colour. This interesting local 

 form recalls Mecha^iitis franis and flies like the latter in the Cauca Valley in Colombia. 



mergelena. In C. mergelena Hew. (35 a), from Colombia, the median band of the hindwing is reduced to a black 



spot at the apex, which is connected with the broad black distal border. At the base of the forewing there 

 megalopolis, is further a proximal yellow oblique band, which is divided by a large, triangular black spot. — In mega- 

 lopolis Fldr., likewise from Colombia, this black spot is absent, so that a broad yellow oblique band is formed, 

 as in Mechariitis macrinus. The yellow spots at the end of the cell on the other hand are small, and also the 

 white marginal dots on the hindwing. 



callispiJa. C. callispila Bates (35 a), from Costa Rica, has a black-brown forewing with numerous yellow spots 



and red-brown base. The hindwing is red-brown with dark distal margm, blackish apex and spot at the end 



eleis. of the cell. — In cleis Bates, from Panama, the yellow spots in the disc of the forewing are much smaller. 



The distal margin of the hindwing and the spot at the end of the cell are united into a large patch in the apical 



mylassa. third. — As mylassa Dbuce describes another form, from Veragua, with broad black apex and distal margin to 



leucania. the hindwing, which, however, are not confluent with the spot at the discocellular. — leucania Bates, from 



Panama, is similar to callispila, but has white spots in the forewing which form an oblique band at the en,d 



of the cell. The hindwing has dark distal margin and a narrow longitudinal band. 



decumana. C. decumana Godm. (& Salv. (= centralis Stgr.) (35 b). This fine, large species and especially the local 



excelsa. form excelsa Fldr. recall the similar Ituna lamirus and Olyras montagui. The markings resemble those of 

 callispila; the yellow spots are larger and transparent. On the hindwing the spot at the end of the cell is ab- 

 sent. In decumana the base of the forewing is black-brown, whilst excelsa has a red-brown stripe along the 

 median vein. Moreover, the hindwing on the upper surface of decumana is uniformly red-brown in the disc, in 

 excelsa a transparent oblique band runs from the apex to the inner margin, decumana flies in Panama and 

 Costa Rica, whilst excelsa comes from Colombia. — Stichel erected the genus Oreogenes for these two forms, 

 but the characters in the neuration are not constant. 



vallonia. With C. vallonia Heiv. (35 b) we come now to a group which is distinguished by a broad, transparent band 



in both fore- and hindwing. The forms are all indigenous to eastern South America, especially Brazil. In 

 vallonia the yellow oblique band of the forewing forms a semicircle. In the cell is placed a triangular black 

 spot. The band of the hindwing is transparent red-brown. The antennae are yellowish, with dark base. The 

 species occurs on the Upper Amazon and in Guiana. — In the somewhat larger daeta Bdv. and the following 

 forms the band of the hindwing is yellow, antennae dark with yellow club. The apex of the forewing in daeta 

 is broadly black with 3 large white dots. At the hinder angle is placed a red-brown spot, whilst in the very 

 euryanessa. similar, but larger euryanessa Fldr. (35 b) this angle is black. The latter form has very delicate, transparent co- 

 louring, even in the apex of the forewing. The black oblique band before the end of the cell of the forewing 

 is posteriorly broad and dentate, in daeta posteriorly reduced. Finally in daeta and the following forms the 

 base of the hindwing beneath is yellow, but in euryanessa red-brown. The two forms occur together in numbers 



. . in central and southern Brazil in the dense virgin forests. — Larva and pupa of euryanessa according to Seitz 

 are stout. The pupa is rounded, yellow-brown, darker at the wings, adorned all over with small black wavy markings. 



daetina. — daetina Weym. is a very rare form of daeta with dark mahogony-brown ground-colour and broad black bands and 



margins. In addition to the two yellow bands there is a yellow spot on the discocellular of the forewing. — As 



evanescens. evanescens (= melphis Hbn.) I designate a very light, transparent form of daeta. Not only the very broad, light 



yellow band of the hindwing, but also the whole disc of the forewing is transparent yellowish. The red-brown 



colour is confined to the base and a spot at the hinder angle of the forewing and also a narrow stripe at the 



laphria. distal margin of the hindwing. — laphria DU. (35 b) is another' very similar species from central Brazil. 

 Size and markings as daeta, but' not transparent. The white spots in the apex of the forewing smaller. Across 

 the end of the median a further black streak. The eggs of laphria are laid in clusters on the leaves of a Solanaceae. 

 The young larvae are yellow-brown with dark head; later they have 3 dark dorsal stripes which are connected 

 by transverse lines. The pupa is short and stout with metallic surfaces at the sides. The pupal stage lasts 

 about 11 days. 



melphis. C. melphis Godt., from the Antilles, which is unknown to me in nature, is said to have black forewing 



with 3 pale yellow-red bands and 3 white dots in the apex. The hindwing is yellow-red with black costal and 

 distal margins, and also a median band, which does not reach the distal margin.
