ARICORIS. By Dr. A. Seitz. 719 



form. nov. (143 c) is a very small pygmean form flying in May in (the town (if) Goyaz. — nociicoelum /nrm. iKxiicoi-hnn. 

 vov. (14:3c) is a form from Obidos, quite hlaek with white (lot'<, (he brown at the ))a-<e of the wings having 

 disappeared except some traces of it. — sontella Schs. (143(1) finally is the form from Parana; here there are smi/rllii. 

 only (jiiite few white dots, on the upjier sin-face of the body none at all : tiie shape of the body and wings, moreover, 

 deviates considerably from the othei' yj///e(//,7-forms, so that I doubt whether it belongs to Stalurhiis; the shape 

 nuich lather resembles Apodenriu stalachfoidcs from wJiich. howevei-. it differs by tlie silvery white (in the latter) 

 abdomen whicii is red-brown in sotitellit. — In venezolana jonii. nov. (143 c) the brown-red colouring is )'e]>laced rrnrrjohnin. 

 by a light orange, so that it resembles the following sj)ccies. In some places rather common. 



S. Susanna F. (143 d). Similar to pJikgin. but recognizable by the shape of the distal orange band siixKinm. 

 which stands only in the apical part on the forewing. Besides there are never white or black dots on the orange 

 parts of the wings. Near Rio de Janeiro the distal orange band on the fore- and hindwing is broad and indented 

 in the middle of its proximal border; in Espiritu Santo these bands are already narrowed and in sjtecimens 

 fi'om San Paulo they are interrupted. South Brazil. 



S. euterpe L. Black, only the orange bands in the distal parts of the wings are present, no orange mirrpi'. 

 at the \rA<e. The black part of the wings covered with white dots and small longitudinal spots. — latefasciata hiifid^riiiid. 

 Stgr. (143 b) which we figure from the Itaituba, has broader orange bands than typical euterpe from Guiana; 

 and adelpha Slgr. (143 d) from Obidos, Para and other places on the Lower Amazon has the orange band only (kIcIiiIki. 

 in tJic forewing, in the hindwing it is above absent altogether and beneath only faintly noticeable. Common. 



S. magdalenae ir«'. (143 c). This and the following species imitate ]\le.c}Kniiti.H I'esp. Melinaen, whereas mcu/iliilniai: 

 the models of the preceding species were Actincte. The apical part of the forewing contains 2 white macular 

 rows, vvhei'eas in the whole proximal part of the forewing the orange colour is jiredominant. Black are some 

 discal spots of the forewing, its inner margin, and the margin as well as a longitudinal stripe of the hindwing. 

 Colombia, where also, though at olher habitats (Rio San Juan), the form cleove l-^tgr. occurs exhibiting only tlmn-. 

 one while macular row in the apical part of the forewing. Rarer. 



S, calliope. Above orange-red with black stripes and spots, and a black, white-spotted apex of the 

 forewing. As the typical calliope L. (143 b) the form in Linnes collection ought to be looked u])on as correct, ralliojir. 

 From Surinam; the spots of the middle stripe of the hindwing are sepai'ated by the red-orange veins, under 

 surface almost exactly like above. — In terpsichore form. nov. (143 c) from French Guiana the black is eonsi- li'r/i.^iirlKirr. 

 derably increased, the middle stripe of the hindwing no more brok(3n up into spots, the apex of the forewing 

 broader black etc. — eugenia Or. (= calliope auct.) (143 b) has the hindwing entirely black except a red longi- fugi-iua. 

 tudinal stripe; Surinam, but at different habitats fi'om those of the typical form. — crocofa Stich. (= calliope rmcolo. 

 Clerck) has distalU^ yellowish-tinged forewings; this yellow discoloration occurs in all the modes of marking 

 and is not bound to any place. — voltumna Stick, has the same light-yellow discoloration as crocota, but beneath, voUininia. 

 except a costal stripe, quite black hindwings. It is mentioned from Ecuador; but the Ecuador-specimens before 

 me exhibit the black under surface of the hindwings, but above they are orange-red, without any yellow. — 

 bicolor Stgr. has the apex of the forewing likewise orange-red, not broad black, but only cjuite narrowly bordered hirnlor. 

 in black, with 4 or 5 black punctiform spots. — Common. 



S. phaedusa Hl)n. (143 d). Wings hyaline, with black veins and margins, marginal area broad orange. pliai'dKnn. 

 In Guiana-specimens also the inner-marginal part of the forewing is hyaline; those from the Amazon (Obidos) 

 exhibit the latter dusted with violet. — In exul form. nov. (143 d) from the Kouron River opposite the Devil's iwnl. 

 Island the orange in the marginal band has disapj^eared except some fahit traces. — h\ phaloe Stgr. (143 e) plmtof. 

 from the Upper Amazon the orange is greatly increased and the disc of the forewing scaled in violet. — In 

 duvalii Perty only the hindwings have a bread orange marginal band faintly passing over only to the anal iliira/ii. 

 angle of the forewing; the hindwings, however, are like the foi-ewings violet except small strigiform spots in 

 and behind the cell. ■ — ('ommon. 



S. zephyritis Dalm. (= margarita Bat.) from Guiana greatly approximates the preceding species, ^riiln/riii.s: 

 but it is recognizable by the white-powdered under surface of the hindwings; on the forewings the inner-marginal 

 part is violet, on the hindwings the costal part is black, the other rest of the wings hyaline, with black veins. — 

 evelina Bllr. (143 d) from the Amazon arc zephi/rill.^ in which also cellules 1 b and 2 in the forewing are dusled ,'i-rlhui. 

 with a bluish grey. — Not rare. 



S. lineata Guer. (143 d). Wings black, between the veins narrow hyaline streaks, befcjre the apex of liiimid. 

 the forewing an orange crescentiform spot. Lower Amazon. In specimens from the Rio Madeira the orange 

 spot grows twice as large and has an oval shape. At other places in the Amazon District it grows, on the con- 

 trary, smaller and may disappear except faint traces; this is trailii Btlr. (143c). Raver. 



97. Genus : Aricoris Ww. 



This geims differs from the jjreceding by the mimicry being confined to the female sex which it has 

 altered to the greatest extent. The only species not being sexually dimorphous resembles a Satyrid, but still 

 it camiot lie properly regarded as mimetic, since it has a somewhat different flight from that of the equally 

 large Evj/tt/chiii which might have served as models. This species, moreover, deviates from the other Aricoris,
