fi26 EUSELASIA. By Dr. A. Seitz. 



in the anal part more intense black radiaiy rays, but it seems otherwise to be closely allied to tulione; 



from Surinam. 



ihiisnchht. E. tliustielda Mschlr. is said to be above velvety blackish brown, beneath similar to mys, but 



the second transverse stripe of the forewing distally fringed; Surinam. Does not lie before me. 



rafiisd. E. cafusa Bat. (121 f). A transition from eulione to eustachius. The upper surface is blackish-brown 



as in eulione; the under surface resembles that of eitstachius, but the black eye-spot on the under surface of the 



hindwing before the middle of the border is considerably larger, mostly also the ground of the wings darker, 



greyer. The $ is coloiu'ed and marked like the ^, but the transverse stripes beneath are broader and brighter. 



Hieo)!sp)>(ra. Guiana, Amazon and Ecuador, not rare. — inconspicua G. and S. from Central America is certainly only a 



$-form of a differently named (J; maybe it belongs here, unless it be the $ of an euryone-iovm. 

 cusiaclnns. E. eustacliius. A^ery variable, above mostly with red, beneath marked veiy much like licinia (121 f). 



In our figure the marking of the under surface is unfortunately missing altogether, but it is almost exactly 

 that of the form figured as aurantia (121 f). It varies by more or less developed submarginal spots on the under , 

 surface of the hindwings as well as by their ground-colour appearing sometimes more yellow, sometimes brow n 

 or grey. Unless cafusa being above entirely blackish brown be only a unicolorous form of eustachius, it has above 

 iiiys. always red which appears, for instance, in the smaller mys H.-Schilfj. lighter, almost like in aurantia. The latter 

 exhibits more miniate hindwings with a broad dark costal margin. — As the red occurs in almost any distri- 

 bution and probably varies at every finding-place, we have denominated here only the more conspicuous forms: 

 rhodoH. rhodon foriri uov. where it is confined to a sector in the hindwing, and fervida Btlr. where the forewings are 

 ii'i-vida. gj^tirely black, the hindwings red with a dark ray from the base to the middle of the border; from Costa Rica 

 and Surinam. Specimens from Colombia exhibit the centres of all wings brightened by brown-red, and from them 

 there occur all the transitions to typical eustachius. The butterfly has a veiy vast range, from Central America 

 aurantUi. to Peru. — auratitia Btlr. and Drc. (121 e) from Central America is presumably only an adaptation of the upper 

 pmciila. surface to chrysippe (121 f) flying there; — whereas procula G. and 8. from Costa Rica with an almost entirely 

 black upper surface being only tinged in red-brown at the base of the wings, forms the transition to e^dione. ■ — 

 seryiii. sergia G. and *S'. (121 e) approximates procula by the forewings being coloured almost just the same; it exhibits 

 however, also above on the hindwing the red sector of rhodon; likewise from Central Aiiierica. — A most con- 

 licinia. spicuous form is licinia Godm. (121 f) flying in Guiana with phoedica and effirna and exhibiting like them a 

 aiheiui. large white spot at the distal margin of the hindwing. — In atliena Hew. (122 a), from Guiana to Ecuador, the 

 white a.rea of the hindwing of licinia is yolk-coloured, whereby it resembles the upper sui'face of gelon-'^, but 

 the under surface is quite different, like in licinia. The species is locally not rare and specimens from the same 

 countries may have a very different upper surface, the under surface, however, is more constant. 

 iin/.siii-ii. E. mystica Schs. (142 c) resembles above an eustachius, being intensely tinged in yellowish-red, but 



the postmedian line of the under surface of the hindwings does not round into a hook, but it is sharply angled. 

 Costa Rica. 

 rhrij.fi ij III- . E. chrysippe Bat. (= labiena Hew.) (121 f). q above bright fiery red, $ yolk-coloured with black 



margins of the wings; at once recognizable by the unicolorous yellow under surface exhibiting only before the 

 margin of the hindwing a series of black dots. Central America. 

 plaridKs. E. placidus nom. nov. (= aurantia G. and S., nee Btlr. and Drc.) which has been figuretl on t. 121 f as 



,,aurantiac'i'\ is hardly in any way connected with the 7nys-groiip. The forewings above are quite the same 

 as in eustachius, but the hindwings have a broad black border. Immediately recognizable by the quite silvery, 

 unmarked under sm-face of both sexes. The $ may be above entnely brown, but the disc of the forewing is 

 mostly yellowish-brown and sometimes the middle of the hindwing is also brightened by yellowish. Costa 

 Rica and Panama, on the Chiriqui locally not rare; it flies early in the morning. This species is peculiar for 

 the coiu'se of the veins; it has on the forewing only two subcostal veins both of which branch off before 

 li'iicopkri/- the cell- end. — leucophryna Schs., likewise from Costa Rica, is beneath one-coloured silvery like placidus, 



""• but above more diffusely and darker brownish-red, the hindwings with a very narrow dark margin. 

 hicronymi. E. hicronymi G. and S. (122 h). Above blackish-brown with dark-red brightenings, beneath with 



colouis and markings quite similar to eulione or eustachius. In the north of the range there occur two forms 

 of the (^; such with entirely blackish-brown forewings and such with a red flame in their basal part. We have 

 figured the former. Both exhibit on the hindwing a red ray from the base towards the anal angle. Mexico 

 and Central America. — From South Brazil I possess a (J forming an evident transition to the mt/s-form and 

 being, therefore, probably better placed to eustachius. On the upper surface of the hindwing another fiery ray 

 runs from the base under the apex, cutting off the costal part. — Apparently not common. The $ is always 

 dingy dark brown, without any red, but recognizable by the under surface resembling the ^J iind not easily 

 distinguishable from the allied $ of eulione. 

 violrtia. E. violelta Bat. (121 i). The under surface of this species and the following one exhibits, on a brightly 



(mostly orange) coloured ground, the median line distinctly double, not at first straight and then bent into a 

 hook before the inner margin of the hindwings, but slightly curved, often finely undulated and often with a 

 knot in the middle of the hindwing. Before the middle of the border of the hindwing a larger eye-spot, above
