670 LYROPTERYX. By Dr. A. Seitz. 



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

 tinued on t]ie hindwing. Colombia; l^ing before me from the Upper Rio l^egro, 800 m, collected by Fassl. 

 juturna. — juturna Heic. is C[uite a similar form from Ecuador, the $ of which has the red band of the forewing only 

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



zancta. N. zaneta Heic. (129 c). In the (J of this Ecuador-form, being vevy closety 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 hind^ving along the margin. The abdominal sides of the ^J exhibit an extremely 



fine j^ellow streak. 



manco. N. tnatico Sndrs. (129 d). The ^ has a thin red median streak across both wings and behind it 



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



fuhninatrix. extinct in some parts. If they are entirely broken up into small spots, we have the form fulminatrix Fldr. 



Instead of red (as they fij' near Pacho, Colombia), there occur also orange-banded 2$ as we ha-ve figured 



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



iindiyii. 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 $9 it is difficult to obtain two specimens from the same flying-place. The denomination of the side-forms, 



such as butleria Drc, lindigii, cMrcmtiaca and so on, is therefore of little value.- The i^^ are not very rare. 



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



inccndiaria. aAi the costa of the hindwing (= incendiaria Thieme) or it may be entirely absent except few small scales; 



the 9? belonging to them also exhibit above deviations in the glaringly-coloured median band. 



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

 heUiana. spots have already become radiatiformly arranged pointed wedges. In beltiana Hew. (129 d) from Central 

 America (Co.sta Rica, Nicaragua) the blue wedges are traversed bj" a white median streak (in the 9 broader 

 dii-a. than in the ^). — In diva Sigrr. (129 c) flying in Colombia the scarlet spots at the middle of the inner margin 

 vetulonia. 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 

 lariindfi. 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 approxi- 

 mating the 9? of vetulonia is 

 inijaretlm. N. ingaretha Hew. (142 e) which ought alreadj^ 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. — 9? 

 decorated with a -RTcath of submarginal white cuneiform rays. Beneath, however, the hindwings show a 

 very^ large red inner-marguial 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: L^yropter^'x Ww. 



This genus is immediately^ recognizable by the very broad wings and the clumsy body. The costal 

 margin of the \sings 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 uniformly 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 submedian and the lower median vein. 



apoJlunkt. L. apollotlia Ww. (129 a). This species is unmistakable; the inner iwo thirds of the wings are above 



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

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

 alieady in the c-entre of the wings; the inner part of the wings is spotted in purple. These spots may be 

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

 whitish, while the corresponding 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 Stick.) or darker blurred spots; nor 

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

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

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

 quarter of the wings and beneath less red spots. — The 9$ ^.re beneath coloured like the (^(S, but above 

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