 spots partly show through above, so that the upper surface has also red guttiform spots. Moreover, the rays 

 are more intensely white, in Bolivians from Buenavista quite purely white. According to the abundant

41. Genus: JSTotlieme Wiv. 



The species formmg this genus attains scarcely half the size of Lyropteryx, but still it approximates 

 the latter genus and the allied Necyria. In the veins the sole deviation consists in the cells of the wings being 

 not so oblique, but more straightly cut off, whereby a transition is formed to Monethe. Ihe formation 

 of the antennae, the palpi, the vaulted forehead are like in Lyropteryx, but the eyes are larger, the abdomen 

 more slender, at the sides not glaringly coloured pnd the body somewhat more strongly haired. The No- 

 theme are easily recognized by the shape and the sinuous yellowish or whitish median band of the wings. 

 They are met with singly on open spaces in the woods where they bustle about in the sunshine.

 a very fine silvery-blue line, being sometimes only indicated by tew small scales. Specimens from Cuzco in 

 Peru are onlj" half as large as tj'pical specimens from Guiana, and the median band is more regular and 

 of a purer whiie; for Peruvian specimens Stichbl proposes the name of diadema: but as he states its ocurrence diadema.

 (32 i) it is more irregular, on the hindwing spotted in rusty yellow at the costa and the anal angle; likewise 

 from South Brazil. Not rare and distributed over the whole of Tropical South America. 



42. Genus: Mouetlie Wu: 



The species forming this genus are closely allied to each other. They are black and pale yellow 

 coloiu'ed butterflies, rather small, in the structure of the body similar to the LyroiMryx, but distinguished 

 by the triangular forewings being sharply angled in the anal angle and by the rather pointed, long-stretched 

 anal part of the hind wings, at which the fringes are prolonged to a short beard. The formation of the head, 

 antennae and palpi do not deviate from that of the Lyropteryx; in both wings the discocellulars are some- 

 what longer, so that the upper median vein branches off farther in front ot the cell-end of the forewing 

 than in Lyropteryx and Notkeme, where it comes almost out ot the lower cell-angle. The forms of the genus 

 seem to replace one another, so that presumably nowheres more than one species occurs.

 apical part of the forewing above is without the j'ellow blurred spot and bene ith the yellow subapical band 

 is narrower; a yellow nucleiform spot being always in the anal part of the hindwing ot albertiis, is entirely 

 absent; it is found wherever the typical form occurs, but presumably scarcely at the same flying-place. 

 Transitions are of frequent occurrence, since the j^ellow spotting varies at every habitat. • — rudolphus G. rudolpJms. 

 a. S. (= cajetanus Sfgr.) (133 a) has much yellow beneath and is above all to be recognized by the under 

 surface of the hindwing exhibiting 5 or 6 small white spots in the brown distal margin. Colombia, especially 

 near Muzo and, therefore, in the so-called ,, Bogota-Collections". — paraplesius from Fi'ench Guiana is a paraples'uw. 

 SxiCHEL-f orm ; the yellow spot of the upper surface is said to be larger and the marginal kernels of the under 

 sorface of the hindwings to be ,, yellowish and partly hazy instead of distinctly white". Both these indivi- 

 dualities, however, vary greatly, rudolpkus is regarded as aj species of its own; but as there are transitions 

 of all the Monetke-iorras to each other, it is very possible that all of them are only local forms of one 

 total species. All the forms are rather common. 



*) According to Stichel, the band of the forewing of diadema is somewhat variable, ,, anteriorly sometimes very 

 little, posteriorly, however, mostly considerably narrowed, at the proximal side almost straight, distally expanded convex 

 or obtuse angled"'.
