Additions: AGRIAS. By A. H. Fassl. 1039 



forewing never touching tlie costal margin in a right angle hut exteiKliiig in a flat how along the costa into 

 the base of the wing, and by the blue c'olour of the liindwing extending to the distal inaigin; besides all tlie 

 southern narcissus are much larger, and often the cornflower-blue also covers tlie red areas which produces 

 a coloristic effect excelling even that of the most variegated sardavaprtlus; all tlie following coloristic varieties 

 (cxcejjt the yellow form) are common to both sexes; the und.er suiface of all the forms is marked and co- 

 loured as the typical narcissus. — Tlie form tapajonus Fassl (113 B b 2) is the southern race being the most 

 closely allied to the type. In the form dubiosa ( 1 13 B b q) — which I took to be a form of clamlia according to 

 the cpiite old specimen taken first on the T.ipajoz — the red bow is downwards widened as far as the submedian. 

 A couple of dubiosa from the Rio Xingu besides exhibits a red pupil in the liindwing in the shajje of a car- 

 mine transcellular spot. The form porphyrionis Fassl (113 Be) lejiresents the transition for which I had 

 long been searching to the most variegated form narcissiis illustrissimus Fassl (113 Be q) which almost en- 

 tirely resembles above a chtudia w;/(7/r(e//, whilst another specimen resenibleti sardanapalus belsazar. On the Rio 

 Maures I finally captured beside the typical narciss-us tapajonus-'^ also a magnificent aberration with a golden 

 yellow band of the forewing — ab. icterica Fassl being in the colouring analogous to the northern form chrysotaenia iiii-rim. 

 from which, however, the Maue.s-insect differs considerably by exhibiting the characteristica of the southern 

 races, the flat bow of the forewing and the blue colour being spread across the whole surface of the liindwing. 



Of the forms of .4. attiydoti the following are to be ranged in the species ■pericles as they have in com- 

 mon with it a rust-coloured yellow or red body, a similar base of the liindwing and the inclination to a blue 

 preapical embedment in the forewing which blue colouring is in variegated specimens like the blue of the liindwing 

 distally besides bordered with green festoons. Tiiereby the ^;encZes-group differs from the pureh- Andine forms 

 of amydon in which these marks are always absent; the races of pericles are besides almost invariably much 

 smaller, the very long apical strigae of the forewing always show through above also in the q,^ as 2 or 3 

 very large yellowi.sh-white dots. 



In case my present expedition *) should be .successfully completed, probably all the non-Andine forms 

 having hitherto been combined with amydon will have to be rearranged in pericles by the discovery of the 

 very rare variegated transitions to the latter species, so that the eastern foot of the Cordilleras would then 

 form the natural frontier between the range of A. amydon and pericles, as is also the case with many other 

 closely allied species of lepidoptera, e. g. Papilio harmodius and ariarathes the range of which is divided by 

 the same line. 



It has hitherto been proved for certain that the, northern forms A. anrantiaca and trajamis belong 

 to pericles. the former representing merely a coloristic variety of the latter, since both forms fly at the same 

 time and place near Obidos as well as to the north of Manaos. Beside a (J of frajauus from Obidos with 

 a faint dark blue preapical reflection of the forewing. I possess a J" of aurantiaca from Manaos with a blue 

 embedment at the .same place but also already a dark blue disc of the liindwing. Still more than these speci- 

 mens do, the figured form praxiteles (113 Be ^) proves the relationship to pericles. representing nothing else itm.rildes. 

 but a ,^ of frajauus, in whicii the jireapical spot of the forewing already exhibits a tendency to a green bor- 

 dering as in pericles; I took the insect near ]\hiiiaos. 



The typical frajanus shows the .same orange-red colour as the figured praxiteles. By Feuhstokfer 

 speaking in his description of frajanus on p. 573 of a purple spot of the forewing and dark red powdering 

 on the liindwing it happened that I described frajanus once more as pericles biedermanni which name has now 

 to be placed as synonymous to frajanus. since also Mr. Lathy (Paris) has indisputably identified the tj^jes 

 of frajanus in an English collection. The white wedge-shaped streaks of the liindwing on which Fruhstokfer 

 in his diagnose lays such great stress, are moreover sometimes absent in specimens from Obidos, almost in- 

 variably in those from Manaos. 



Of the 'pen'cfe.s-forms from the South Amazon the Rio Tapajoz unites the most shades at the same place. 

 Here we meet with variegated red-banded specimens allied to the t\'pical pericles of the Solimoes, and in 

 which the distal bordering of the blue areas exhibits bright green festoons, as well as all the transitions 

 to quite scantily coloured specimens showing but minute traces of blue and green; the very same gradation 

 is exliibited by the cell-banded forms there {.vanthippus Sfgr.). in one of the specimens I captured there we 

 even notice no trace whatever of blue and green, and this plain blackish-yellow specimen recalling the f-co- 

 louring is at any rate and presumably the most poorly coloured of all the ^o of Agrias, which I denominate 

 pericles q ab. tristis. /ci.'./i.s. 



Whereas formerlj^ only a $-forni of pericles being similarly coloured like this was known, I succeeded 

 in takmg besides several V? being alike, in which the black preapical zone of the forewing is profusely strewn 

 with golden green scales; sometimes the veins traversing this green area are besides lined dark blue — V 'ib. 

 chlorotaenia Fassl. Still more singular is a $ which I at first mi.stook for phalcidon-anaxagoras, before I knew (■hlorotuc- 

 the legitimate V of the latter, which, however, certainly also only represents a variegated $ form of pericles: 

 mirabilis Fassl (113 B d $); it exhibits a subapical embedment similar to chlorofaenia, though of a blue colour mirahili.i. 

 in which on the contrary the veins are lined green. In the liindwing the orange-powdered base is followed
