1040 Additions: AGRIAS. By A. H. Fassl. 



by a blaclv discal area, then comes a broad, dull dark blue submarginal border distally defined by a fine 

 equally broad green silvery line; the most peculiar feature, however, in this insect is the strangely shortened 

 yellow bow of the forewing. almost looking like a transition to the basal spot of anaxagoras-heivitsonius. 



m^diensis. The Rio Maues yielded a much more constant race of perides — mauensis Fassl — in which there 



is no green festoon at all, the fore-and hindwing being profusely violetti>h-blue; the magnificent bow of the 

 forewing may be purple-red, orange or yellow. The $ is without decorations like the normal one of the Tapajoz- 

 forms, but it invariably has a dark metallic green reflection in the hindwing at the place where the strigae 

 are in the northern forms. Only a single $ from Maues is more variegated with a similar though much duller 

 cnromda. blue decoration than the ^ and a light orange-red band; I denominated it $ ab. coronata. 



The Rio Madeira has by no means supplied a transition from mauensis to the typical perides, but a very 

 peculiar lepidopteron which one might almost take to be the S of per ides mirahilis-'^; it looks above and 

 beneath very much like the figm'ed hewitsonius fournierae-^ from the same habitat, and has lil^ewise an orange 

 basal spot of the forewing not extending beyond the cell: then follows a dark blue zone ending in a narrow 

 ffreen border at the distal margin; just as dark blue with a fine green bordering which, however, is more 

 intense analwards, are the hindwings. Particularly the latter circumstance, besides the remarkably long 

 apical strigae beneath showing through towards the apex of the forewing as 3 purely white dots, the rust-co- 

 loured yellow base of the hindwing above and no less the small size of the insect are certain proofs that it 

 aJtasvenis. belongs to perides. I name this new form ahasverus; it has been discovered by my collector A. Luiz Steympl, 

 and it is the only representative of perides known hitherto from Madeira. Its great resemblance to a form 

 of hewitsonius flying at the same habitat is by no means a sporadic occurrence in the variations of well sepa- 

 rated insects of the same genus; I only mention as similar examples: Heliconius melpomene and vesta vicu- 

 lata near Santarem, Morpho-hecuba and meteUus near Obidos, Morpho cisseis and perseus crameri near Parin- 

 tins etc. 



gloriom. That also .4. jenUnandi Fruhst. and its recently described variegated form gloriosa Lathy — with 



a profuse blue preaiiical embedment in the forewing — are nothing else but southern forms of A. perides resj). 

 of its Matto CTrosso forms, is easily to be made out from the aforementioned common marks of the races of 

 perides. But also tryphon Fruhst. and amydonius Sfgr., of which we have at present too little material, seem 

 to belong to perides. 



On p. .576 we have to insert in A. mapiri in the Sth line from above after the word ,,Agrias'' the 

 word „perides'\ 

 phakidon. A. phalcidoii. I must premise that the range of this species as well as of the close allies and of the 



hewitsonius being connected by transitions, is probably only confined to the Southern Amazon District in spite 

 of some contrarious statements. Both myself and my collectors were for a long time active at different places 

 to the north of the Amazon and Rio Negro without ever beholding a blue Agrias. An entirely typical (^ 

 in the Paris Mu.seum, which merely exhibits a somewhat greyer scent-pencil and is labelled as ,, Obidos", I 

 most positively consider not to originate from there. 



Two geographical forms are also known from the east of Itaituba on the Tapajoz, both of which 

 .vinguen.'iis. invariably exhibit as the principal mark red basal marking on the hindwing beneath, xinguensis Fassl (102 C f ), 

 which is besides somewhat more bluish steel-green, exhibiting smaller ocelli beneath and mostly a large metallic 

 lustrous steel-green spot in the distal half of the forewing beneath, was discovered by me on the Rio Xingu, 

 ruhrohiim- whereas rubrobasalis Fassl forming the transition to the typical form occurs on the northern frontier of the 

 Amazon District from the mouth of the Xingu upwards as far as Santarem and from here the right banlv 

 of the Tapajoz upwards as far as Monte Christo. 



In the blue phalcidon-iorm. paiilus, on p. 576, we must remark that the specimen taken by Dr. Hahnel 

 near Parintins is not a 5 but a (J. I took the very singular $ probably belonging to paulus on the Tapajoz 

 in a single specimen (llSBd $)• 



The tj^e of phulcidon anaxagoras, according to its discoverer H. Otto Michael who also fiunished 

 us with a drawing, by no means exhibits almost entirely black hindwings as Fruhstoefer writes on p. 576, 

 but analogous to my two more ^^ taken near Itaituba it is like a normal pJudcidon-^ also in the hindwing 

 profusely decorated with blue and green. The 2 of anaxagoras (113 B d $) having hitherto been unknown, 

 which I took on the Tapajoz in 2 rather similar sjjecimens, is very much like the 9 of A. hewitsonius (113 B d). 



We likewise figure here the $ of the genuine A. hewitsonius (113 B d) from Teffe, which was hitherto 

 unknown; all the sjDecimens I captured are entirel}^ constant. The figure of hewitsonius S beneath on t. 114 c 

 is of a somewhat too bright green colour; besides the ^ above mostly exhibits a much more extensive green 

 marginal line almost invariably reaching the posterior margin of the forewing and being in some ocJ even 

 rudimentarily continued in the apex of the hindwing.
