844 JEMADIA. By Dr. M. Deaudt. 



series spread before one, as for instance from Fassl's collection; then the differences become more and more 

 obliterated. 



vulcanus. J. vulcanus Cr. nee {Hew. 163 e) has a blue band more on the hindwmg than the preceding species, 



the most proximal of the inner-marginal rays being removed more into the middle and forming a broad middle- 

 band. On the forewing the basal bands are both well developed, the marginal band runs in a straight line to 

 the apical hyaline spots and even beyond them. Colombia, Guiana. 



hewitsoni. J. hcwitsoni Mab. (166 b) looks like the preceding, but the middle band of the hindwing is only very 



short, triangular and almost white. Beneath on the hindwing the 2 black middle bands are united at the costal 

 margin and proximal margin, the latter being all black. Colombia. 



fallax. J. fallax 3Iab. (163 e) likewise resembles vulcanus, but it can easily be distinguished from all the 



species of the functati- groivp by the distal, basilar band of the forewing forming with the lower blue inner- 

 angular streak a single oblique band; the fine marginal band is somewhat more curved. On the hindwing the 

 blue median band is removed more distally, the marginal band being narrow, broadly interrupted by the black 

 veins. The under surface of the hindwings is almost entirely black, the broad black middle bands exhibiting 

 only a fine metallic bluish-green thread between them. Brazil, Colombia. 



patroclus. J. patroclus Plotz (166 c), according to the excellent figure by Plotz, belongs to the punctati, not 



as Mabille thought to the lineati, the species being allied to fallax from which it chiefly differs by the distal 

 basal oblique band of the forewing not coalescing with the inner-marginal ray, but being separated afar. On 

 the forewing there is only a small, square, postdiscal hyaline spot, above it there is a small blue oblique spot; 

 the 5 apical hyaline spots are relatively large and well developed. The hindwings are marked the same, but 

 the blue marginal band is considerably broader and coherent. On the under surface the 2 black middle bands 

 are separated afar by the blue colour and neither coalescent at the costal margin; before the black border, 

 in the blue colour, there is besides a fine, black, undulate line from the upper median vein to the costal-marginal 

 vein. Described from Peru. 



lisetta. J. llsetta Mob. & Boull. In the following species of this group the distal margin of the hindwing, 



at least in the ^, is deeply concave with 2 distinctly dentate anal lobes, in the $ mostly rather rounded. In 

 lisetta the marginal band of the hindwing consists only of 4 or 5 separate, small spots and does not extend to 

 the proximal angle; the blue middle band is entirely absent. Described from Peru. 



lecerfi. J. lecerfi Mab. <& Boull. (163 d) has a still shorter marginal band of the hindwing, extending only 



to the lower median vein, and a short, triangular, pale blue median band. On the forewing above the blue 

 marginal band only extends to the postdiscal hyaline spot. Guiana. 



menechmus. J. menechmus Mab. (163 d) differs from the two preceding by a broader, coherent marginal band 



exhibiting a break only near the proximal angle. The blue marginal band of the forewing extends to the small 

 apical hyaline spots. Brazil and Colombia. 



gnetus. J. gnetus F. (= megalesius Hbn., sosia Mab.) (163 d) has been a somewhat doubtful species which 



I, however, unhesitatingly unite with sosia; it has the broadest marginal band of the hindwing, extending 

 coherently to the proximal angle where it bends round and passes over into the inner-marginal ray; the two 

 proximal inner-marginal rays are flown together to a broad, white-blue surface, the median band is absent. 

 On the under surface the 2 black median bands are not directly united at the proximal margin, only coalescent 

 at the costal margin. Widely distributed in Colombia, Guiana and Brazil. 



hephaestus. J. hephaestus Mschlr. (= zamorae Mab.) (163 e) is very similar, on an average somewhat smaller, 



above with a narro^^■ed marginal band and middle inner-marginal rays, the median band being likewise absent. 

 The under surface of the hindwing shows an entirely black proximal margin and the 2 black median bands are 

 also united at the proximal margin. From Surinam as far as Colombia and Bolivia. 



II. Group : lineati. Instead of the 4 dots at the prothorax a bluish-white trans- 



verseline. 



polyzona. J. polyzona Latr. (= jamina Btlr.) (163a) is easily recognizable by the great extent of the blue 



colom', particularl}^ the blue costal margin, the postdiscal hyaline spots being scalariformly arranged below 

 each other, and 4 apical spots. On the hindwing beneath the middle black band is forked like a Y on the 

 middle radial. Guiana and Brazil. 



zimra. J. zimra Hew. (163 a) is similar, but much less blue, mostly with an intensely greenish tinge; 



particular!}^ the marginal band of the hindwing is very narrow. BrazU to Paraguay. 



aniirnla. J. albuftiia 3Iab. (163 b) has above no blue rays or only traces of them below the median hyaline 



spot of the forewing, and beneath the black median band of the hindwing is not shaped like a Y, but broadly 

 coalescent with the proximal one at the costal margin and proximal margin, like in the hospita group. Brazil.
