64 PERRHYARIS. By J. Robee. 



'/•^f leptalina. — leptalina Bales (^ pisonis ''"'V'/r.) is the form from the Upper Amazon. — sabata I'rulmt., from Colombia, 

 •/^/f sabata. jg smaller than pnndosia, has a diffuse transverse band on the discocellular and more deeplj' incised black 

 distal margin, the underside is yellowish, the white spots of the forewing are smaller and the black bands 

 /!// Ophelia, sharper. — Ophelia Fruk-^l., from Peru (October), shows a stronger development of the black markings, larger 

 white spots on the under surface of the forewing and a more intensivelv red band on the underside of the 

 /^£ ludovica. hindwing. — ludovica Fruhst. is the dry-seasonal form of ophelia ; it is decidedly smaller and has the sub- 

 anal band on the hindwing narrower (February). 



-/'^J marana. I. marana Douhl. (20 d), from Ecuador, is similar io paiido.fia, but has on the upperside broader black 

 margins and on the underside of the forewing a black subapical band as well as a similar median band on 

 the under surface of the hindwing, which in the basal part is divided by a red-yellow band ; the ?, which 

 is yellowish white above, stronger j'ellow beneath, has on the upper surface of the forewing a black sub- 

 apical band and broader black margins. . 



-^T'r pisonis. I. pisonis Hew. (20 d), from Colombia and Peru, differs from ki^aha L'eak., from Honduras, in that 



y.^/ kifaha. the black subapical band is complete above and beneath. Both forms have beneath at the margin of the 

 forewing small white spots and at the distal margin of the hindwing a red-yellow macular band. 



7. Genus: I*errbybris Hbn. 



This genus differs from Fieris by the three-brancbed subcostal, there are no other sharp structural 

 differences, but it is well characterised bj- the Hebconine-like style of marking, sti'ongly developed in the 

 cfcf only beneath but in the ?¥ on both sides, which makes it probable that it belongs to another evoluti- 

 onary stirps than the Pieris-species. Following the example of Kaye, we have removed the species with four- 

 branched sulDCOstal, which are also well differentiated from Perrhyhris in facies, especiallj- bj' their slighter 

 sexual dimorphism, and placed them with the preceding genus Itahall/a. 



/4(^ lypera. P. lypcra KoU. (20 e), from Colombia (and Central xAmerica?), is in the d' white above with black 



apical part of the forewing and broad black distal margin on the hindwing, under surface of the forewing 

 like the upper, hindwing yellow with broad black margin, a similar longitudinal band in the anterior part, 

 in which is placed a short red band starting from the inner margin, and a black stripe at the costal margin. 

 ? black above and beneath, similarly marked on both sides, on the under surface of the hindwing as in 

 /f/ paravicinii. the cf a red half band. — paravicinii Frulist., from Ecuador (Balzabamba), has longer and narrower wings, 

 a decidedh' narrower black distal margin, on the underside of the forewing the cell is lighter, the apical 

 spot somewhat smaller, on the underside of the hindwing the margin narrower in the posterior half, the 

 subbasal Imnd white and pointed, central area light yellow proximally, distally white instead of dark j^ellow. 



pyirha. P. pyrrha /•'. (= iphigenia SJmh) is distributed from Central America to South Brazil (Sao Paulo) 



and from the east coast to the Upper Amazon. The upper surface of the (fcf presents the facies of a typical 



White, whilst the ?? are similar to the Heliconines. The so-called type-form piiirha occurs in Surinam, from 



digitata. which digitata Fruhst., from Espiritu Santo, is distinguished in the & by a narrower black distal margin 



//^ pandora, and in the ? by an uninterrupted yellow band on the fo^-ewing. — The cTcf of pandora foi-nu nor. (20e, f), 



from Rio de Janeiro and S;io Paulo, have a completeh- _bla«k hindwing except for a black mai'ginal line, 



and reduced black markings on the forewing, the ?? a much broken, light j-ellow (commonly sulphur-j'ellow) 



-7^/ eieidias. band on the forewing. — eieidias lihn. is probably a seasonal form from Surinam, with entirely white hind- 



/^ lucasi. wing in the cf and very narrow black median band on the hindwing in the ?. — lucasi Fruhst., from Ca- 



venne, is a ?-form with very broad vellow band on the forewing, the red median band on the hindwing 



■'*•' pamela. being almost without dentition. — pamela Cr. is a ?-form with stronglj' developed black markings on the 



T^/t amazonica. hindwing. — amazonica Fruhst. (= pyrrha 'S'^'".), from the Upper Amazon, has in the cT a narrow black 



margin on the hindwing and in the ? a moderately dentate band, red above and yellow beneath, on the 



-/y/ incisa. hindwing. — incisa Fruh.'ft., from Bahia, ftas in the cf a broader margin on the hindwing than amazonica, 



in the ? the much broken yellow band of the forewing is broadly margined with black near the base and 



'^l^ malenka. the red band of the hindwing is produced into tine points. — malenka Hen:, from Venezuela and Colombia, 



has in the d" the upper surface of the hindwing entirelj' white and the under surface with only a few pale 



mai'kings, the ? has narrower wings, two i-ed-brown bands reaching almost to the margin and only small 



ostrolenka. subapical spots, whilst OStrolenka Sfgr., from Chiriqui and Panama, is almost without markings beneath in 



bogotana. the o^ and the ?? are much darker beneath than ma/enka-^. — bogotana Btlr. {-^= Mylothris bogotana Btlr.), 



from Santo Fe de Bogota, is in the ? similar to malenka : the yellow-brown median spots of the forewing 



and the somewhat shorter subraeilian longitudinal stripes are sulphur-yellow at the margins: above and well 



separated from them are two j-ellow, obhquel}- placed spots and aloove the cell three oblong spots of the 



/(7. same colour in the obhque subapical row instead of the quadripartite band in malenka. — glessaria Fridist., 



from Ecuador iXapo and Cocai. has in the cf above the marginal band deep black, but moderatel_v broad,
