572 ' ■ AGRIAS. By H. Fiuhstoei'ek. 



and inclined to give way to every geographical and climatic iiitlueuce. In (iinydun,, at least in the C'olondiian 

 specimens, we have i*j register the interesting fact that the red area of the forewings may proceed from the 

 base of the wing as in Agrias chvudia and A. sardimiipnlus; but that it is also proximally displaced by the black 

 ground-colour, so that instead of a convergent area, there remains only yet a Ijand-like l)i-ightening reaching 

 from the costa to the inner margin. The median area of the forewings intermits from yellow to red, l)ut we 

 hitherto know yellow-banded Jc? only from C'ulondjia and Bolivia. The under surface is of plainer markings 

 than in A. clamlia and A. sardanapalus; it is on the hindwings, also in the specimens being above red, yellow 

 with black rosettes, without a variegated filling between the black bands. The ocelli are black with blue- 

 white pupils, in one form {trajdmi'H) almost white. Of a very constant extent is the black antemarginal band 

 of the hindwings, the distal margin itself is yellowish, with the exception of ferdinnndi where it appears pre- 

 ponderantly whitish. Less constant is the prcapical band of the under surface of the forewings. It appears 

 very narrow in scune Colombian forms, uncommonly broad in boliviensu, and remains yellow in all the Andine 

 specimens, white in those from (Jentral Brazil. The upper surface of the hindwings is subject to by far the 

 greatest influences, numbers of specimens exhibiting a sparkling blue sardanapaloid disk and others showing 

 an insignificant blue spot being distally and anally displaced; then there are sj)ecimens without any discal 

 spotting, with a unicolorous cover of the hindwings and, finally, such with greenish or yellowish small adnerval 

 stripes of the submarginal zone. 



There arc no exact statenif-nts about the liabits. F.\SSL has aeen them thcling round the tops of high trees, and 

 even when they approach the bait on the ground, they eoiue down from above in a wide spiral, flying for a nn'niite 

 round the bait, whereat only a red line is recognizable owing to their niiiibl<'ness. The ?$ .seem to prefer resting on the 

 ground, at leas', my travelle- .Mich.vei.is has suipr s((l a ',' in Surinam drinking from a puddle. 



ainijdiiH. amydon Hew. is a form resemljling our figure 115 d, but differing from it by the absence of the whitish spots 

 of the forewings and a considerably larger and lighter blue disk of the hindwings; the chain of ocelli on the 

 under surface of the hindwings appears also coherent, not dissolved into single components as depicted in 

 om- figiu'e. There exist specimens with a red area, running thiough fiom the base as far as close to the inner 

 margin of the forewings, exhibiting generally somewhat less blue on the hindwings than in the name-type 

 iiiuzjhisin. presented by Hewitson. Such ^(^ were denominated muzoensis FniJi.-if. Specimens with a narrow oblique 

 band from the costal to the inner margin of the forewings. which may be pale reddish-yellow or almost orange- 



jrijiUlna. ycllow were separated as frontina Ft-iihst. frontinii stands between (Uiiydon- Heir, and zenodortid Hew. Upper 

 surface like in zenodortis. but the apical spot somewhat more ol)soletc and the discal band orange, sometimes 

 chrome-yellow, but never carmine as in diin/i/oii nor bi'ight ycllow as in zciiodonis. This discal area is exactly 

 as in zenodorU'S, but narrower than in (imydon. The discal spot of the hindwings somewhat .smaller than in 

 zenodorus, but considerably larger than in amydon. The under surface of the wings completely agrees with 

 iiviydon, except the lighter colour of the disk of the forewing. Described according to 5 sj)ecimens in Godmax's 

 collection and 1 ,3- of my collection. This subspecies of aniydon was collected by S.MjMON near Fiontino in Colom- 

 l)ia. Hewit.son's collection likewise contained I specimen which was arranged together with an Af/ria.^ ferdi- 

 nnndi and two (ttiiydoii. labelled .juiiydon''. Of late some more J,^ were discovered nearly without a blue disk 

 of the hindwings, inhabiting preferably the eastern slope of the East Cordilleras of Colombia, whereas on the 

 Upper Rio Negro at an altitude of about SOO m above the sea-level likewise at the eastern slope of the East 

 hirscHi. Cordilleras, j'J have Ijcen oljserved without any marks of a blue spotting and denominated larseni Fd.^.'^l. The 

 $ of amydoti remained extreu'ely rare and was only recently discovered by Fassl. It is half as large again 

 as a normal ,^, of a more compact shape and more rounded forewings as well as hindwings. The ground-colour 

 is not so intensely black, but more a dark greyish brown. The red arc of the forewings is duller and without 

 the sparkling lustre. The three small suba[)ical spots being obsolete in the ^ arc Himost as large again and 

 distinctly yellowish white, but separated by the veins, on the under surface, however, not broader than in 

 the ^ and likewise forming a band. Upper surface of hindwings entirely dark greyish-brown, without a trace 

 of blue or red. Scent-tuft absent as in all the Agrias-'-}'^. Anal angle very obtuse, nearly rounded off. Under 

 surface almost just as glaring as that of the ^\ the marking hardly different, only the black ocellated band 

 broader and more coherent, the white-blue ocelli being of the same size and not differently shaped as in the ^. 

 Fas.sl found the $ of amydon, in the comjjany of Anaea 'pmuiriste-'^, pasibuh-'^, Coenoplikhia tirchiduna-^, 

 Prepona neoterpe-'^ and the dimorphous 9 of the red P. praeneste, and the unpropcrtiomxtely large 5$ of Agrias 

 itedon and A. amydon were considered the most precious booty from those wild primeval forest valleys into 

 which the discoverer had several times retired as if forced by magic power, in spite of the violent fevers he had 

 luidergone thci-e, and notwithstanding the numerous poisonous siuikes and the worst victualling to be thoiighl 



b'KjAaiiii. of. — As bogotana Frulist. there is a specimen in the British Museum approximating .4. jerdinandi (115 c). 

 It is, above all, larger than jerdinandi, has less dentated hindwings, a lighter red discal band of the forewings 

 and a lighter under surface. Furthermore, the bands on the hindwings are considerably broader than in jerdi- 

 nnndi, so that the yellow ground-colour is compressed to narrow bands, and the blue cyespot-j)upils of the 

 ■ ■iiniduniwi. black submarginal band are somewhat larger than in Brazilian specimens. — amydonius 'V/ryr. (115 d) was basi-d 

 upon a ij from Pebas on the Upper Amazon. The magnificent i)ur])!c-i'ed of the forewings, small carmine basal 

 spots and three anteterminal yellow streaks of the hindwings distinguish this local race. We have figured the
