670 LYKOPTERYX. By Dr. A. 8eitz. 



the preceding ones; from the following it differs by the red band of the forewing in the $ not being con- 

 tinued on the hindwing. Colombia; lying before me from the Upper Rio Negro, 800 m, collected by Fassi,. 

 jut lima. ■ — juturna Hpav. is quite a similar form from Ecuador, the $ of which has the red band of the forewing only 

 half as broad and no blue spots of the hindwing. The species seems to be rare. 



uniiUi. N. zanela Hev. (129 c). In the rj of this Ecuador-form, being yevy closely allied to the preceding 



species, the metallic macular band has been converted into a continuous stripe running in the forewing right 

 across the centre, in the hindwing along the margin. The abdominal sides of the (J exhibit an extremely 

 fine yellow streak. 



inanco. N. ttianco Sndrs. (129 d). The (J has a thiia red median streak across both wings and behind it 



a l)luish-green metallic macular band. Both the bands vary and may grow so thin and faint that they are 



jiihii'uiatrix. Qxtmct in some parts. If they are entirely broken up into small spots, we have the form fuhiiinatrix Fldr. 

 Instead of red (as they fly near Pacho. Colombia), there occur also orange-banded $5 as we have figured 

 according to a specimen probably originating from Muzo. The yellow $-forni is more common going by 

 /iiidiijii. the name of lindigii Fldr., although this name ought be used only for those specimens the orange median band 

 of which exhibits a pale violet reflexion. — In this species, the median band varying enormously in width 

 and delimitation, it is also hardly possible to find two $$ being alike, because owing to the relative rarity of 

 the $0 it is difficult to obtain two specimens from the same flying-place. The denomination of the side-forms, 

 such as butleria Drc, lindigii, aurantiaca and so on, is tiierefore of little value. The (J,^ are not very rare. 

 They also show deviations, for instance the red median band may disappear except a tapering small band 



iiiroidkirki. 'At the costa of the hindwing (— incendiaria Thieme) or it may be entirely absent except few small scales; 

 the $2 belonging to them also exhibit above deviations in the glaringly-coloured median band. 



N. vetulonia. This species already forms the tiansition to the next genus. The blue submarginal 

 licltiaiia. spots have already become radiatiformly arranged pointed wedges. In beltiana Hew. (i29d) from Central 

 America (Costa Rica, Nicaragua) the blue wedges are traversed bj" a white median streak (in the $ broader 

 diva, than in the 3*). ^ — In diva 'SVr/r. (129 c) flying in Colombia the scarlet spots at the middle of the inner margin 

 vdidonia. of both wings being visible in beltiana only beneath are present also above in a luminous red. — In vetu- 

 lonia Hew. (129 d) the radiatiform spots are broader and the red spots are increased beneath not far from 

 laninda. the base; from Ecuador. — larunda G. and S. originates from Guatemala; it exhibits a blue reflection on 

 both surfaces and the white rays are longer, beginning already in the centre of the wing. — Greatly ai>proxi- 

 mating the $? of vetulonia is 



hiijui-clhd. N. ingaretha Hew. (142 e) which ought already to be reckoned to the following genus, since it has 



entirely the structure and shape of Lyropteryx. The uncommonly broad wings, of which the forewings exhibit 

 a short costal margin and inner margin and a border being curved in uniform bows, are like in vetulonia- — $$ 

 decorated \vith a wreath of submarginal white cuneiform rays. Beneath, however, the hindwings show a 

 very lai'ge red inner-marginal spot of an almost triangular shape. The species is before me from Orosi (Costa 

 Rica), from the Coll. Fassl; Salvin and Godman mention it from Nicaragua. 



40. Genus: Ijypo|>teryx \Vw. 



This genus is immediately recognizable by the very broad wings and the clumsy bodj'. The costal 

 inargin of the wings is relatively short, the distal margin, however, particularly at the forewing, very long 

 and bent uniformly. By including diadocis Stick, the genus does not remain confined to the species which 

 are closely allied to each other and uniformlj shaped, with a round border of the hindwing, but it also 

 contains forms with a long-stretched anal part of the hindwings. Another characteristic may be the great 

 distance between the subraedian and the lower median vein. 



iijiolioKia. L. apoUonia Wn\ (129 a). This .species is unmistakable; the inner iwo thirds of the wings are above 



velvety-black, the outer third is traversed by bluish-green, white-dusted rays, the hindwings near the base 

 with a red guttiform spot; beneath scarcely the (basal) half of the wings is velvety-black, as the rays begin 

 already in the centre of the wings; the inner part of the wings is spotted in purple. These spots may be 

 aM or partly faded, and there are before me several unsymmetrical specimens, where they are on one side 

 whitish, while the corresjjonding spots of the other side are red; this is, therefore, only an abnormity. A 

 similar case may be the discoloration of the rays into lighter (canens Stirh.) or darker blurred .spots; nor 

 are the rays always of the same length, which variation is probablv due to the different catching-places 

 of this rather local animal. Brazil pnd Bolivia to the north as far as Ecuador. — From Colombia to Gua- 

 ch-adas. temala flies the form cleadas Drc. (129 a, b), the ^ of which has shorter rays that are confined to the outer 

 quarter of the wings and beneath less red spots. — The $$ are beneath coloured like the ^,^, but above 

 they have sometimes a red margin; the latter is in the normal apollonia-^ confined to the hindwings, but
