Publ. 23. r. 1924. Additions: SIDERONE; ANAEA. By J. Rober. 1041 



iUthough my prior presumption that A. fhalcidon and hewitsonius are merely local races of the same 

 species had been very strongly opposed, the discovery of an extremely magnificent intermediate form on the 

 Rio Madeira, A. foumierae Fassl (103 C f (J) must be considered as a confirmation of my opinion. The blue foumierae. 

 colour above is of a still much more magnificent and lighter metallic lustre than in the genuine hewitsonius-^; 

 a narrow, green border only occurs in the figured specimen; in 4 other ^J^J of foumierae it is entirely absent; 

 a rather broad black distal margin likewise recalls hewitsonius. Beneath there is no trace whatever of a green 

 colouring or of a basal bordering; instead of it the yellow colour is spread across the whole light tints of 

 the under surface, which is not the case in any other of the phalcidon- and hewitsonius-vnces known hitherto. 

 ^4. foumierae has 2 different $ forms; the tjrpical most magnificent form on both wings resembles the (J; 

 it is by one third larger, the blue is lighter, metallic light violet and without any trace of green. The other 

 very different $ form — $ ab. calliste — is somewhat smaller and less variegated, it only has a duller blue callisie. 

 before the orange spot, turning soft steel-green towards the apex and costa ; the hindwing likewise only shows 

 a dull discal blue decoration. 



At the same time and place I also took 2 quite constantly aberrant (^(^ of foumierae in which the 

 orange basal spot of the forewing is reduced to a narrow longitudinal stripe dissolving towards the lower 

 cell-margin into fine yellow atoms in the blue ground-colour: form, viola Fassl (113 B). viola. 



Whilst A. foumierae looks like an enlarged form of Callithea hatesi ahneean.a from the same habitat, 

 the form viola involuntarily reminds us of the magnificent Catagrarnma excelsior michaeli Stgr. occurring at 

 the same place. 



Although we may be in doubt whether the new magnificent insect is to be placed to phalcidon or 

 hewitsonius, probably already the nearest future will yield some more interesting intermediate forms connecting 

 phalcidon with heiuitsonius also with respect to their very different under surfaces. 



Genus Sideroiie. 



Sider. marthesia Cr. (p. 577) has been found again by Mr. A. H. Fassl near Itaituba on the Tapa- 

 joz; we had 1 2 from Fassl's collection figured (102 Cf); the under siirface corresponds to that of confluens 

 (116 a), but the forewing shows a yellow ground-colour. 



Genus Auaea. 



A. suprema Schs. (= zilcani Rhl.) (102 C e) is one of the most remarkable and most magnificent suprema. 

 species of this genus and has only recently discovered by Mr. J. F. Zikan near Facenda dos Campos near 

 Passa Quatro in the southern Minas Geraes at an altitude of 1600 m, the small insect in the male has about 

 the shape and size of falcata (120 Dc), but the body is less robust; the upper surface is bluish-black with 

 a slight reflection and has a broad, almost golden red costal-marginal band, but the costal margin itself is 

 bluish-black beginning from the middle of the discal cell, the distal margin of the forewing is, like the apex 

 of the wing, somewhat broader and reddish ; the hindwing has a somewhat paler red distal-marginal band of 

 about 3 mm width. The under surface resembles that of iyrianthina (118 e). The $ forewing above shows 

 a ground-colour similar to that of the $ of Chrysophanus virgaureae (Vol. I, t. 76 a), the costal margm is 

 black, in the centre a broad black band growing broader in front towards the rear and with unequal margms, 

 being particularly distally sharply dentate in the areas of the wing; in this black band there are three large 

 spots of the ground-colour; the hindwing is black with large, yellow, coherent spots and with an antemedian row 

 of equally coloured, sharply defined spots. The under surface shows a more distinct black marking than in 

 the (^, at the end of the discal cell of the forewing there is a black spot. As to the early stages, F. Zikax has 

 published the following account *): ,,The globular egg, being somewhat flattened at its upper pole, is feebly 

 corroded, of a lustrous greenish-white, and has a diameter of scarcely 1 mm. It is singly deposited on the 

 underside of leaves of a tree-like species of Croton (according to Dr. Rechingbr Croton gossypiifolium 

 H. R. K., called ,,Sange di Drago^^ by the natives), mostly at a considerable height. The total amount 

 of eggs of a $ is about 200. The small larva leaves the eggs 11 days after the ovipositing. It is then 3 mm 

 long, dingy green, with a dark brown, black spotted head and one subdorsal and one lateral row each of 

 scanty bristles. After about 2 weeks the first casting of the skin takes place. After this the small larva 

 is about 10 mm long, dingy green, with the characteristic, quadrangular, red-brown spots (of the ^naea-larva, 

 of which the saddle-spot is the most conspicuous. Below the stigmata the larva is coloured yelloAvish. Its 

 skingis densely covered with low, yellow tubercles with short black bristles, the head showing a crown of 

 spines. After the second skinning the gi'ound-colour of the larva has turned cinnamon-red. The red-bro\^^l, 

 interrupted dorsal line and the lateral spots of the same colour already correspond with the adult larva, 

 and so do the spining and colour of the head, whereas the integument (the skin) exhibits the former state.
