LEUCOTHYRIS. By B. Haensch. 147 



I give the name of flexibilis spec. nov. to a species from northern Peru which is similar to dolabella. It is smaller flexibilis. 

 ' and has a narrower whitish oblique band, constricted in the middle. At the hinder angle of the forewing is placed 

 an oblong vitreoiis spot, as in crispinilla, from which flexibilis is distinguished by the double spot in the apex. — 

 From Bolivia comes another very similar form, which I call virina form. nov. It has a white oblique band like virina. 

 dolabella , but the other A-itreous spots are colourless, not dusted with white. At the hinder angle of the forewing 

 there is a vitreous spot as in flexibilis, but the black oblique band across the end of the cell is quite narrow, 

 Unear trom the median onwards. 



L. perspicua Btlr. (38 e) is very similar to janarilla, considerably larger, with subapical band instead perspicua. 

 of the double spot, and also a pear-shaped spot at the hinder angle of the forewing. It flies with the allied 'onega 

 and epicharme at the Upper Amazon. — Onega ^^•. has a broader white oblique band on the forewing and the onega. 

 hindwing is black with a narrow, curved vitreou^oand behind the middle, which is shaded with dark at the inner 

 margin. — In epicharme Fldr. (38 e) the vitreous band of the hindwing is broader, wedge-shaped, broadest at epicharme. 

 the inner margin. 



L. amazona Hsclt., from the Upper Amazon, is similar to the preceding, with uniformly broad oblique cmiazona. 

 band on the forewing, without the vitreous spot at the hinder angle. — Another similar form, which I call ramona ramona. 

 form. 710V., has colourless vitreous spots except for the white oblique band, the spot at the hinder angle being elongate- 

 quadrate. The median band of the hindwing is narrowest in the middle, the broad costal margin forming an 

 angle at the S""* median vein. It flies near Sara-yacu on the Ucayali. 



L. crispinilla Hpffr. (38 e), from eastern Peru, is distinguished from the preceding by whitish dusting crispinilla. 

 and narrow black costal margin to the hindwing, which does not enter the cell. 



A species very similar to the preceding, which I call L. enania spec. ?io»., flies also in Peru. It is appreciably enania. 

 smaller and has different neuration, as well as narrower bands and margins. Especially noteworthy is the black 

 streak across the cell of the forewing, which is here placed in the prolongation of the l"*' median vein, whilst in 

 crispinilla it is nearer to the base. 



L. didymaea Hew., from Bolivia, has a similar pattern to virina, without the double spot in the apex didymaea. 

 of the forewing. It may be recognised hj the black oblique band across the end of the cell of the forewing, which 

 forms a streak from the median to the distal margin, as well as by the narrow, uniformly broad distal margin 

 of the hindwing. 



In the following forms the band-like streak through the cell of the forewing is absent. 



L. borilis spec. nov. I thus name a similar species to didymaea, from Pozuzo in South Peru, with the borilis. 

 wings dusted with white, without the streak in the cell. The distal margin of the hindwing is much broader. 



L. synnova Hew. (38 f). This rare and beautiful species is very strikingly distinguished by the orange synnova. 

 colouring (in the figure this is too dark) from the otherwise similarly marked species, such as ramona, etc. 

 According to Bates it only flies on the north bank of the Upper Amazon, near Tunantins. 



L. quintina Fldr. (38 f) is said to come from Venezuela, I know it only from Bolivia and Peru. It quiniina. 

 has white-dusted wings with black margins and an oblique band at the end of the cell of the forewing, which 

 is gradually narrowed posteriorly. — The very similar alexina Hew., from Peru and Bolivia, has colourless alexina. 

 wings, only the subapical band of the forewing is dusted with white. The markings strongly recall Itho^nia 

 ardea, which, however, is distinguished by the neuration. 



Next follows another small group with broad, rounded wings and black streak through the cell of the 

 forewing, of which L. astraea Cr. (39 b) is often mistaken for some other species. The typical form comes asiraea. 

 from Guiana. It has a broad, black oblique band on the forewing, which is only forked shortly before the 

 distal margin ; also quite faint red-brown colour in the distal margin of the hindwing. — thimei Oberth. {-= flora thimei. 

 Hew. Exot. But. f. 68), from the Piio Magdalena in Colombia, is very similarly marked, but has no red-brown 

 on the upper surface and beneath only at the base. Moreover, the distal margin of the hindwing is narrower 

 and uniformly broad. — flora Cr., from Cayenne and Surinam, is a larger form with broad margins and b nds flora. 

 and also red-brown markings in the distal margin of the hindwing. At the distal margin of the forewiug 2 

 distinct white spots are marked off by the branches of the oblique band. — On the Lower Amazon flies a 

 smaller form of astraea, with roundish apex to the forewing, which I call antaxis form. nov. It has a light autaxis. 

 red-brown, dark-bordered distal margin to the hindwing and a similar spot at the hinder angle of the forewing. 



An extremely similar species from the Middle Amazon, which I call. L. stradopsis spec, nov., has dif- stradopsis. 

 ferent neuration and more pointed apex to the forewing. The upper arm of the lower discocellular and also 

 the middle discocellular are longer. The oblique band of the forewing is rather gradually narrowed beyond 

 the 2'''^ median, the 3"''' is not thickened. 



In L. egra Hew. (39 b) the black oblique band of the forewing is very broad, runs on the ^"^ median egra. 

 vein and is connected at the other side with the black inner margin. The species flies on the Amazons.
