OF THK AMAZON VALLKY. 517 



;j. Danais Kkesimus, Craiiun-.

Tliis is tlie common species in the interior of tlie country, it is very aljundant at Kija, 

 on the Upper Amazons, where Z). Erlppm did not occur.

 The six descriijed species of tliis yeiius di Her from each other by sucli sli^jht cdiaracters 

 (small dill'erences in colours, and in the arraui^cment of tlie pattern on the wini^s, beini; 

 the only ])oints wliich distini;-uish them), that tliey mii^ht fairly be considered as varieties 

 of one only. I liavc not yet seen specimens, however, wliich connect all the forms 

 together, and these are mostly the products of diilerent ^coipraphieal an>as ; it will be 

 more convenient therefore to treat them independently, than to combine them under the 

 head of one polymorphic species. A ij^ood collection of specimens from all parts of the 

 area of distribution of the g-enus would here be very instructive. We should then be able 

 to aset'rtain the metro])olis and ])rol)able area of oi'ii;ination of each of the various forms. 

 I have seen only L. lldlut in collections from S.E. Brazil. L. ulertjatis is peculiar to 

 Columbia and the T'pper Amazon region ; but a strikini;' variety of it prevails over the 

 type in this last-mentioned district, and another, L. Falcs (Felder), occurs on the Itio 

 NeijTO. L. Clcobcva (which is scarcely more diH'erent from L. ti/crf/atis than the just- 

 mentioiu'd L. atcrgotis, \ ar., is fnmi its type) is reputed to occur in the West India Islands. 

 At Para three forms, imdudini;' L. Jla/ia, are found toi-'ether ; ami here some intermediate 

 varieties occur, makini.^ it probable that the sei^re^'ation of the cpiasi-species is not in 

 that district complete.

This species occurs in the Amazon rei^'ion at I'ani, and on the hanks of the Tapajos. 

 It is also an inhabitant ol" Surinam. Cramer's lin'ure is made from an example rather 

 aberrant in the markinifs of the hind wind's; otherwise it au'rees very well with the 

 sijceimens I have before me. 1 have a variety from Para which connects this form with 

 /.. llolJa. 



2. LvcoKKA I'AsixrNTiA, Cramer. 



Papilo Pasinu/itia, Cram. I'ap. Ivxot. t. .510, A, 15, C. 



This form occurs thnumlidul the whole of the iVmazon reunion, iVom 1X° to 70° \V. 

 hm'j;. The extreme westei'ii examples, found at St. Paulo on the Cpper Amazons, 

 show a chanj^e of colour in the yellow irrciiular belt of tli(> fore wiiiu', which ha- accpn'red 

 the same oranire-tawnv shade as the rest of the wiuis. The same substitution of colour
