;it all, under aurfacc similar to A. r/ilue obklonn Fruhst. $ chalky white with sharp-serrated reddish-l)r(.)\\n 

 median band. Antenna white, in black ringlets, the tip black. 



B. Species of the Group Peridroniia Bsd. 



A, feronia is the species being known the longest and to be found the mo.st frec^uently in the col- 

 lections. Above recognizable by a milky-blue or bluish-grey zigzag-band and coiling round the ocelli, the colour 

 varying in intensity according to the locality. A red worm-shaped spot in the forewing-cell always distinctly 

 noticeable. The black cells of the hindwings with one blue ringlet with white pupil. Under surface greyish- 

 white. Hindwing with delicate yellowish or greenish lustre. In Central American specimens the hindwings 

 are ochreous, a characteristic mark which is found as a form of condition (mandragora Men.) also in Brazilian 



iarniiiliiiia. specimens, though very rarely. — farinulenta subsp. nov. Ground-colour darker greyish-green than in feronia. 

 The white spots at the apex and round the forewing-cell more extensive . Under surface of the hindwings simi- 

 lar to that of feronia f. mandragora, covered with intensely dull ochre-yellow, but never as dark-yellow as in 

 the larger ^4. guatemalena Bates. Still Godmann and Salvin were induced by this hue on the under surface 

 to identify the feronia-Ta.ce of Central America with the darker guatemalena being also ornamented with larger 

 iii'iiihii-iH. ocelli. Range from Texas, Mexico to Panama. Nomenclatural type from Honduras in my collection. — insu- 

 laris subsp. nov. A small elegant race being above almost light-blue, beneath uncommonly light and with mother- 

 of-pearl gloss, from the Isle of Trinidad. From Santa Lucia and Hayti there are likewise ^4. feronia recorded 

 niiiiUUii. which certainly represent new races. — nobilita subsp. nov. As nobilita I denominate those Venezuelan and 

 t!olombian specimens that are conspicuous for their moi-e extensive and prominent white spotting on the fore- 

 wings and exhibiting in both the sexes an intensive and lighter blue spotting than feronia from Cayenne and 

 Icniitid. the Amazon. — feronia L. (I05c), the nomenclatural type, original^ described from Surinam, is lying before 

 me in a large series of corresponding specimens from Cayenne, Obidos and the Upper Amazon. Staudinger 

 has specimens from the Ucayali and Pernambuco, and on the Andine side feronia' reaches as far as to the Chan- 

 chamayo. Cramer knew an especially dark $ from Surinam which he depicted, while Hxjbner presented an 



f7(/i(/</////«(/r/. especially light (J. — catablymata subsp. nov. is to denote the Central Brazilian specimens in which the light 

 pure blue appears as if covered with a grey curtain. The under surface is sometimes just as abundantly hued 

 in yellow as in the Central American areal from. This deviation in the colouring was depicted already in 1857 



iinuiih(ii/iir(i.ii'< mandragora Men. Further to the south, the specimens are steadily growing darker, until we come across 



ohuinbntta. obuiTibrata subsp. nov. in Paraguay. Habitus smaller, wing-contours more roundish, upper surface of all the 

 wings darker, the white .spotting powdered with sombre blackish-grey, all the black bands broader and the 

 blue spotting almost disappearing. Under surface 2iiore extensively spotted in black than in typical feronia. 

 Specimens being very closely allied to obumbraVt are already found in Santa Catharina, while such from Sao 

 Paulo forin an also geographically natural transition from catablymata to obumbrata. 



A, guatemalena. .V remarkable species hitherto known from the Peninsula of Yucatan to Panama, 



was first ascertained b}' myself for Brazil where it very rarely occurs in Espiritu Santo, guatemalena excels 



A. feronia considerably in size. On the upper surface of the hindwings the black median zigzag-band appears more 



prominent ; ocelli of the hindwings larger, with a blue periphery and white pupil being not nude as in ^4. feronia, 



but surrounded b^^ a fine blue wng. Under surface of the hindwings reddish or covered with pale ochre-yellow. 



<i(l)i,ieiii!i. — eupolema subsp. nov.^ifi a distinct race from Yucatan. The apical- and median-parts of the forewings 



throughout lighter-spotted than in the nomenclatural type from Central America. Type in the Coll. Stau- 



niiiniiarirc. DINGER. — marmaricc subsp. nov. is most strongly contrasting with the preceding form and must be considered 



as the darkest areal form. Upper surface in both the sexes dull greyish-blue instead of greenish-blue as in the 



Honduras specimens. The subapical spots of the forewings being whitish in the nomenclatural type, are over- 



unaiciiitdr- powdered by blackish also in the $. Orizaba and Guadalajara (Mexico) in the Coll. Fruhstorfer. — guate- 



""■ malena Bates (105 c) is found in the whole of Central America. The $ has an elegant, peculiarly greenish-blue 



(•/(//((. colouring of the upper surface. — elata Fruhst. { 105 d), an excellent geographical branch, is immediately 



distinguishable from the northern forms by the whitish, instead of livid-covered apical part of the forewings. 



Under surface : the black spotting appears reduced whereby the white maculae gain in space and the yellowish 



colouring of the hindwings grow paler. Espiritu Santo, 1 o 2 $$ in Coll. Fruhstorfer. 



A. iphthime resembles above A. feronia so much that it is easily comprehensible that Kirby took it 

 to be a variety of .4. feronia. Also to Staltdinger it came hard to diagnose this species. He recognized that 

 there occur two more species of Ageronia in South Brazil beside .4. feronia L., and denominated a species 

 not being .4. epinome Fldr. with ,,fallax". The description of ,,fallax", however, is much more identical with 

 the form denominated as epinome by Felder. Let us, therefore, quite briefly remark that the A. iphtfiime- 

 races are immediately distinguishable from the analogous ^4. /eronta-subspecies, by a reddish-brown apical 

 hue on the under surface of the forewings, which is absent in .4. feronia, and by the broad brown distal margin 

 of the under surface of the hindwings. The »';>M»'me-branches, however, are lacking the worm-shaped
