bordered in l)Iack. Botli the wings traversed hy a greyish-violet narrow sulunargiiial I)and with a jtroxiniai 

 black line running parallel to it. Clasping organs analogous to those of .4. caUipJmne, valve, however, without 

 the dorsal boss, wliereas the ventral projection is more pronounced, clunicula rising from a narrower base. 

 Contour of valve just like the preceding species, ap])roaching the A. (ilaln-group by the short, compact shape. 

 Type in my collection from Rio Grande do Sul. — perga sub.sp. nov. was recently discovered in Santa (!atha- jiriya. 

 rina and differs above by narrowed white and orange marking. The under surface is more variegated, the 

 white streaks and spots are overhued by violet. The white median band of both the wings is also interiorly 

 bordered in black, and on the wings a transcellular row of 5 distinct white spot.s appears, which are hardly 

 suggested in falcipennis. 



A. epizygis spec. nov. (109 b). ,^ above very similar to crtUiphane. the white median band of all the rpi-nijU. 

 wings, however, much broader so that the yellow preapical spot is confluent with it. This spot eostally much 

 more extensive, forming a triangle instead of a narrow band as in calliphnne. The reddish anal spot of 

 the hindwings somewhat more imposing than in caUiphatie. Under surface: the white median band t)egins 

 only at the anterior median, above it there are, however, three very broad yellowish-white internerval maculae 

 advancing as far as the subcostal veins. Distally to them and pai'allel, a row of 5 or 6 greyish-white roundish 

 dots traverses the wing-centre. The scheme of markings described just now remind us of euboen Fldr. from 

 f!olombia and Itopurdus (goijama Schaus) from Paraguay. The violet bands like in cdUiphune, but somewhat 

 more subdued, the postmedian bands of the hindwings violet instead of predominantly reddish-browii and 

 with reddi.sh-brown longitudinal line. Clasping-organs entirely different from those of A. colli phaiie and A. 

 fidcipennis, much more allied to those of the group of A. iphicla and .4. abia. .\ppendage of the uncus elon- 

 gated. Valve likewise more slender in spite of a ventral expansion, the exterior part much longer, more sharply 

 dentate. Clunicula up to the very high point broader, type from Sa'o Paulo; a ,^ from Rio Grande do Sul 

 with somewhat broader median band in the collection of Prith.Storfer; besides a ,^ from Paraguay in the 

 Tring-Museum. 



A. rufilia .syjec. nov. Shape of the wings more pointed than in A. epizygis. forewing with 2 obsolete niii/ia. 

 ochreous subajncal dots being absent in epizygis. Under surface: the white central areas on Itoth the surfaces 

 broader and with a lighter reddish -brown border, just like the yellowish-white subapical maculae and their 

 distal parallel band. The whole other surface of all the wings greyish-white instead of violet traversed by fine 

 light-red lines. Clasping-organs of this species characterized by the uncommonly neat marking of the under 

 surface are prominent by the remarkably broad, relatively short dorsal tooth. This protuberance itself is 

 more robust than in the allied species, more densely set with strong spikes; valve ventrally slightly curved: 

 point armed only with two minute teeth. Rio Grande do Sul, very rare, only 2 ,3,^ in my collection. 



A, epona spec. nov. An insignificant species combining the characters of the group of .4. ipJiicht and rpniin. 

 A. ■plesaure. The upper surface resembles ^4. iphicla (107 a), ^4. thessnlin ( 109 b) and A. cibin (109 a), the isolated 

 preapical spot is, by its scpiare shape, the most similar to A. thes.sriliit Fldr. The extent aiifl course of the 

 median band re-iemble .4. abin and .4. ciUiph'ine. The under surface differs from that of ,4. epizygis only by 

 more faded transcellular spots. Compared with ^4. plesaure, the whole colouring of the under surface aj)jx>ars 

 duller, a pale bluish-grey being j^revalent. Clasping-organs with extremely short uncus: valve somewhat 

 approaching that of .4. epizygis, though without the inflated protuberance of the lower ])art. In case of intei- 

 mediate stages occurring, .4. epona may ev^entually be united with .4. epizygis. 



A. felderi, a peculiar entirely isolated species, recognizable by the far projecting apex of the fore- 

 wings and sharply delimited, narrow, mother-of-pearl-lustrous, white median band on both the wings. The 

 dark ochreous small preapical spot reminds soinew4iat of A. i.via and na.via. The undei' surface is most charac- 

 teristic by the reddish-yellow ground-colour resembling A. sichaeus and by the band of the hindwings some- 

 what resembling .4. olynthia. Three area! forms occurring from Mexico to Costa Rica: felderi Bsd. described ii-liliri. 

 from Costa Rica, is closely allied with falcata Ood)n. from Guatemala. Both have a smaller preapical spot and Uilmlit. 

 somewhat broader white median band of (he foicwings than jarias ■■siibsp. nov. from Mexico. The latter form is at jdi-ias. 

 once noticeable by a fcnu-th component of the otherwise tripa-rtite apical area, embedded between the anterior 

 and central median. 



A. fessonia Hon. (109 c) forming, together with .4. ce.'itus, a small group, is recognizable by a broad /c.v.w/uVf. 

 white median band advancing to the co.stal margin on the forewings. The band forms an obtuse angle at the 

 cell-apex. The preapical spot uncommonly large, light ochre-yellow. Under surface traversed by dark-brown 

 bands, anal angle reddish-brow 11. The apical spot of the forewings pale yellow w ith reddish embedment. Nomen- 

 clatural type from Honduras, but oc'curring from Yucatan throughout the whole of Central America to Co.sta 

 Rica. Not rare in Western Mexico, also from (luadalajara and Orizaba in the 4'ring-Museum. Specimens from 

 Mexico exhibit a broader white band than ,33 from Honduras, r^,-^ from Costa Rica a more imposing preapical sjiot. 



A, cestus Hev. (109c) is excelled in size by .4. fes.sonia and shows on the forewings instead of a (v-.s/i/.s'. 

 large preapical area only three relatively small rcdflish-brown inacnlac (piitc closely appi'oached to the apex. 

 Venezuela, verv rare.
