ARICORIS. By Dr. A. Seitz. 719 



form. nov. (143 c) is a very small pygmean form flying in May in (the town of) Goyaz. ■ — nocticoelum form, nodicoelum. 

 vov. (143 c) is a form from Obidos, quite black with white dots, the brown at the base of the wings having 

 disappeared except some traces of it. — sontella Schs. (143 d) finally is the form from Parana; here there are sontelUi. 

 only quite few white dots, on the upper surface of the body none at a.11 ; the shape of the body and wings, moreover, 

 deviates considerably from the other phlegia-ioviwn, so that I doubt whether it belongs to Sfalachtis; the shape 

 much rather resembles Apodemia stalachtoides from which, however, it differs by the silvery white (in the latter) 

 abdomen which is red-brown in sontella. — In venezolana form. nov. (143 c) the brown-red colouring is replaced venezolarui. 

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



S. Susanna F. (143 d). Similar to phlegia, but recognizable by the shape of the distal orange band ausannn. 

 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 specimens 

 from Sao Paulo they are interrupted. South Brazil. 



S. suterpe L. Black, only the orange bands in the distal parts of the wings are present, no orange euierpe. 

 at the base. The black part of the wings covered with white dots and small longitudinal spots. — latefasciata latefasciata. 

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

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

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



S. magdalenae Wiv. (143 c). This and the following species imitate Mechanitis resp. Melinaea, whereas maqdalenae. 

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

 rows, whereas in the whole proximal part of the forewing the orange colour is predominant. 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 other habitats (Rio San Juan), the form cleove Sigr. occurs exhibiting only chore. 

 one white 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 upon as correct, calliope. 

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

 surface almost exactly like above. — In terpsichore form. nov. (143 c) from French Guiana the black is consi- ierpsichore. 

 derably increased, the middle stripe of the hindwing no more broken up into spots, the apex of the forewing 

 broader black etc. — • eugenia Cr. (= calliope avct.) (143 b) has the hindwing entirely black except a red. longi- eugenia. 

 tudinal stripe; Surinam, but at different habitats from those of the typical form. — crocota Stick. (= calliope crocota. 

 Clerck) has distally 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, voliumna. 

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

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

 bicolor Stgr. has th^apex of the forewing likewise orange-red, not broad black, but only quite narrowly bordered hicolor. 

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



S. phaedusa Hhn. (143 d). Wings hyaline, with black veins and margins, marginal area broad orange, phaedusa. 

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

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

 Island the orange in the marginal band has disappeared except some faint traces. — h\ phaloe Stgr. (143 e) phaloe. 

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

 duvalii Perty only the hindwings have a broad orange marginal band faintly passing over only to the anal duvalU. 

 angle of the forewing; the hindwings, however, are like the forewings violet except small strigiform spots m 

 and behind the cell. ■ — Common. 



S. zephyritis Dalm. (= margarita Bat.) from Guiana greatly approximates the preceding species, zephynfis. 

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

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

 evelina Btlr. (143 d) from the Amazon are zephyritis in which also cellules 1 b and 2 in the forewing are dusted evelina. 

 with a bluish grey. — Not rare. 



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

 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. (143 e). Rarer. /rai7i(. 



97. Genus: Arlc®ris V/iv. 



This genus differs from the preceding 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 Satj^rid, but still 



it cannot be properly regarded as mimetic, since it has a somewhat different flight from that of the equallj- 



large EuptycJiia which might have served as models. This species, moreover, deviates from the other Aricoris,
