Puhl. 2.]. r. 192 J. Additions: SIDERONE; ANAEA. By J. Ruber. 1041 



Although my prior presum]itioii tliat A. plialcidon and heintsonius 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. fournierae F(tHd (lo;i('f ^'') must be considered as a confirmation of my opinion. The blue fuumU-rm: 

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

 a narrow, green border only occurs in tiie figin-ed specimen; in A other (^^ of fournierae it is entirely absent; 

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

 colom-ing 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 phakidon- and Jieiritmnius-races known hitherto. 

 .4. journierae has 2 different $ forms; the typical most magnificent form on i)oth 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 rulUsk. 

 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 i cpiite constantly aberrant r^^ of journierae in which the 

 orange basal spot of the foi-ewing 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 (113B). )■;„/,(. 



Whilst A. fournierae looks like an enlarged form of Callithea batesi aimeeana from the same habitat, 

 the form viola involuntarily reminds us of the magnificent Catagramma e.veelsior michaeli Sigr. occurring at 

 the same place. 



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

 ketritmuiu.t. probably already the nearest future will yield some more interesting intermediate forms connecting 

 ■phalcidon with hewitsonius also with respect to their very different under surfaces. 



Genus Kidoroiie. 



Sider. marthesia. Cr. (p. 577) has been found again by I\Ir. A. H. Fas.sl near Itaituba on the Tapa- 

 joz; we had 1 $ from Fassl's collection figured (102 C'f); the under surface corresponds to that of confluens 

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



Genus Auaea. 



A. suprema Schs. (= zikani Rid.) (102C'e) is one of the most remarkable and most magnificent 

 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 

 l)luish-l)lack beginning from the middle of the discal cell, the distal margin of the forewing is, lifvc 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 tyrianthina (llSe). The 9 forewing above shows 

 a ground-colour similar to that of the i' of Chrysophanns virgaureae (Vol. I, t. 7(i a), the costal margin is 

 black, ill the centre a broad black band growing broader in front towards the rear and with unecpial marghis, 

 being particularly distally shar])ly 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 equallj"^ 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. Zikan 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. Rechinger Croton gossyjDiifolium 

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

 of eggs of a 9 is about 200. The small larva leaves the eggs 1 1 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 nnn long, dingy green, with the characteristic, cpiadrangular, red-brown spots (of the .4wMea-Iarva, 

 of which the saddle-spot is the most consjiicuous. Below the stigmata the larva is coloured yellowish. Its 

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

 spines. After the second skinning the ground-colour of the larva has turned ciiniamon-red. The red-brown, 

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

 and so do the siiining and cohnu' of the head, whereas the integument (the skin) exhibits the foiincr state.
