L. terpsichore Ww. (= zygaena Stick.) (129 b). Beneath very similar to the preceding, but the red ti-rii^Uh 

 spots jJai'tly show through above, so that the u]iper surface has also red gultiform spots. Moreover, the rays 

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

 material before me, side-rorms are not to be maintained. Brazil, Bolivia, Paraguay; everywhere rare. 



L. dsadocis Stick. (142 i) of wliich only the specimen in iStaitdingbes collection is known to me, being (iiadnciK. 

 copied here, lias on the forewing an orange oblique band and less intense rays which become distinct almost 

 only on the hindwings. From Sao Paulo da 01iven9a on the Amazon River. 



41. Genus: ^otheiiae IFw. 



The species forming this genus attains .scarcely half the size of Lyropienjx, but ,-till 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 oblic^ue, but more straightly cut off, whereby a transitioii is formed to Monethe. Ihe formation 

 of the ante.nnae, the palpi, the vaulted forehead are like in Li/ropteryx, but the ejes are larger, the abdomen 

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

 Iheme 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. 



N. eumeus f". (= ouranus Z)6Z.) (132 i). On a blackish ground we see a bone-yellow, irregular median riininia. 

 band, being on tJie hindwing of a rusty discoloration at the anal end ; before the border of tlie hindwing 

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

 Peru are only half as large as typical specimens from Guiana, and the median band is more regular and 

 of a purer white; for Peruvian specimens Stichel proposes the name of diadenia; but as he states its ocurrence diddniin. 

 also in the Amazon district, Colombia and Ecuador, it seems not to be a delimitable form -'). — erota Cr. erola. 

 (132h) has the median band yolk-coloured. — angellus Stick. (132 i) is the southern form (Paraguay, South aii!/r//H.<<. 

 Brazil) with an irregular, in some places extinct band (= keinicosnieia Stick.). The median band is generally 

 narrower in southern specimens than in those from the northern parts of South America. — In agathon Fldr. (igdilinii. 

 (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: Moiietlie W 



'U\ 



The sjiecies forming this genus are closely allied to each other. Tiiey are black and pale yellow 

 coloured butterflies, rather small, in the structure of the body similar to the Lyropteryx, but distinguished 

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

 anal jKirt of the hind wings, at whicli 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 piesumably nowheres more than one sjjecies occuis. 



M. alphonsus F. (132 i). The forewing exhibits on the basal jiart of the median a yellow cuneiform ^////cdi.m/.v. 

 streak being slightly thickened in the centre of the wing. Beneath grey with distinct black veins. South 

 Brazil. 



M. albertus Fldr. (132i) has above in the disc of the forewing a large oval yellow spot, differs, filhn-iii.^. 

 however, particulaily beneath by showino sharply defined yellow discal spots and no black veins. Colombia, 

 Western Amazon to Bolivia. — In leucobalia Stich. (133 a. as leucoholia) the light spots ot the upper surface Iriiroha/ui. 

 are white instead of yellow; it lies before me only from Bolivia. — In ah. carens form. nov. (133 a) the rarms. 

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

 is narrower; a yellow nucleiform spot being always in the anal part of the hindwing ot albertus, 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. nulnl/ilius. 

 a. S. (= cajetanus Stgr.) (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-CIollections". — paraplesius from French Guiana is a i>iinii,l,sii(.s. 

 STicHEL-form ; the yellow spot of the upper surface is said to be larger and the marginal kernels of the under 

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

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

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

 total species. ^\J1 the forms are rather common. 



*) Aoroi'ding to Stichpii,, the band of the forewing of itiadcma is sonii'what variable, ,, anteriorly sometimes very 

 little, po.steriorly, however, mostly considerably narrowed, at tlu' ])roxinial side aliiinst straight, distally expanded ccmvi-x 

 or obtuse angled".
