64 PERKHVAKIS. By J. Rodee. 



leptalina. — leptalina Buiv^ {= jiisonis N/'/r.) is the form tVojii 1he Up]ier Amazon. - sabata l-nilisl., from Colom])ia, 

 sabatci. ,"y smaller than pundasia, has a diffuse transverse band on the discocellular and more deeply incised black 

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

 Ophelia, sharper. — Ophelia Fnihxt., from Peru (October), shows a stronger development of the black markings, larger 

 wlnte s])ots on the under surface of the forewing and a more intensively red band on the nnderside of the 

 liidovica. hindwing. — ludovica Fnihs/. is the dry-seasonal form of oplielin ; it is decidedly smaller and has the sub- 

 anal band on the hindwing narrower (February). 



luaraiia. I- marana Don///. (20 d), from Ecuador, is similar io I'lnidosia, 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 yelhiw beneath, has on the u])per surface of the foi-ewing a black sub- 

 apical band and broader black margins. 



pisfluis. I. pisonis //'-"•. (20 d), from (Colombia and Peru, differs from ki^aha Urak., I'rom Honduras, in that 



kicaha. the black subapical band is complete above and beneath. Both forms have Ijeneath at the jnargin of the 

 forewing small A\hite spots and at tlie distal mai'gin of t)ie hindwing a red-yellow maculai' band. 



7. Genus: Perrbybriw llhu. 



This genus differs from /'/Vt/.s by the three-branched subcostal, there are no other sharp structuial 

 differences, but it is well characlerised by the Heliconine-like style of marking, strongly developed in the 

 cfc/ only beneath but in the ?? on both sides, which makes it probalile that it belongs to another evoluti- 

 onary stirps than the P/m.s--species. Following the example of Kaye, we have removed the species with four- 

 branched subcostal, which ai"e also well differentiated from f'nrhi/bris in facies. especially by their slighter 

 sexual dimoi'phisiii. and jilaced them with (he preceding genus Ifahnllia. 



lypera. P. lypcra Kotl. (20e), from (^oloiidiia (and f'.entral America?), is in the o^ white above with black 



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

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

 in wliich is placed a short red band starting from the inner margin, and a l)lack stripe at the costal margin. 

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

 paraviciiiii. the o' a red half band. — paravicinii lu-iihst.. from Ecuador (Balzabamba). has longer and narrower wings, 

 a decidedly narrower black distal maigiu, on the nnderside of the Jbrewing the cell is lighter, the apical 

 spot somewhat smallei'. on the underside of the hindwing the margin narrower in the posterioi' half, the 

 subbasal band white and pointed, central area light yellow proximally. distally 'white instead of dark yellow. 



pyrrha. P. pyrrha /•'. [— iphigenia S Inil:) is distributed from tlentral America to South Brazil (Sao Panlo) 



and from the east coast to the L'pper Amazon. The ujipei' surface of the cfcf presents the facies of atypical 

 White, whilst the ?? ai'e similar to the Heliconines. The so-called type-form pijrrha occurs in Surinam, from 

 digitatn. whicli digitata I-'i-iilisf., from Espii'itu Santo, is distinguished in the o"' ])y a narrower black distal margin 

 pandora, and in the ? l)y an nninterrupli'd yelhiw hand on tlie forewing. — The cfcf of pandora jnrui. nor. (20 e, f t, 

 from Hio de daneiro and Sno I'aulo, have a completely black hindwing excejjt for a black marginal line, 

 and reduced black markings on the I'oi'ewing, the ¥? a nuii'li broken, light yellow (commonly sulphur-j'ellow) 

 eieidiax. h-AwA on the forewing. — eieidias lllm. is iirobably a seasonal tbrm from Surinam, with entirely white hind- 

 lacasi. wing in the cf and very narrow black median band on the hindwing in the?. — lucasi Fnihst., from (Ca- 

 yenne, is a ?-form with \ ery broad yellow band on the forewing, the red median band on the hindwing 

 pallida, being almost without denlilion. — pamela 'V. is a ^;'-form with sti'ongly developed black markings on the 

 aiiiazoiiira. hindwing. — amazonica J-'ni/i</. (^ jiyrrha Sh/r.), from the Upper Amazon, has in tlie o"" a narrow black 

 mai'gin on the hiudwing and in the ? a modei'ately dentate band, red above and yellow Ijeneath, on the 

 indsa. hindwing. — incisa lriili.</.. from Bahia. has in the cf a broader margin on the hindwing than (iiinudnini, 

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

 mall-Ilka, the red band of the hindwing is jiroduced into tine points. — nialenka VA //■., i'rom N'enezuela and Colombia, 

 has in the d^ the upper surface of the hindwing entirely white and the under surface with only a few |)ale 

 markings, the ? has narrower wings, iwo i-ed-brown bands reaching almost to the mai'gin and only small 

 ostroh'iika. subapical spots, whilst ostrolenka 'SV'/r., from Chiricpii and Panama, is almost without markings beneath in 

 bogotana. the d' and the ?? are much darker beneath than mnlenku-'^. — bogotana I'ltlr. (^= .\Iylothris bogotana lillr.), 

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

 and the somewhat shorter submedian longitudinal striiies are sulphur-yellow at the margins: above and well 

 separated from them are two yellow, obliipielv iilaced spots and above the cell tliree oblong sjiots of the 

 glessaria. same colour in the oblique subapical row instead of the quadripartite band in nialenka. — glessaria FndisL, 

 from Ecuador (Napo and Coca), has in the cf above the marginal band deep black, but moderately liroad,
