698 DREPANULA. By Dr. A. Beitz. 



near Villavicencio. Here the small oblique band of the forewing is still fairly preserved; in a specimen cap- 

 tured by Fassl on the Rio Negro (East Colombia) also the white oblique band on the forewing is trans- 

 mi-gala. formed into a grey line, the small fusiform band being very narrow. — megala fofm. nov. (133 b) is a form 

 of almost double the size of tantilla, with a very distinct marking, deep colouring, and a broad median band: 

 spectanda. Monte Tolima and the Aguaca Valley. — In spectanda Stich. (133 b) the median band has turned a broad 

 oval, the small oblique band of the forewing, however, to a small narrow stripe, the white distal spot of the 

 traiiKicns. hindwing only beneath distinct. Peru, Bolivia, Ecuador. — transiens forrn. nov. (133 b, c), a mountain-form 

 from Bolivia, is smaller, with a still broader median spot, the small white oblique band of the forewing, 

 which in spectanda is yet distinct and oval on the under surface, being here also nearly vanished. — It 

 lucilUif:. forms the transition to lucilius Hpjjr. in which the median band occupies almost the whole disc of the wing 

 as a broad, below rounded oval, whereas the small white distal bands are absent altogether; this form is 

 likewise found in Peru and Bolivia. — Not rare. 

 riristofrlr<<. S. aristotclcs Latf. (133 d). The two dark wings are traversed in the distal part by a band of sliort 



licrht rays which are particularly beneath distinctly prominent, in front of it a yolk-coloured median band 

 ochrotaenia. being aloove and below pointed. Colombia (Monte Tolima). — In ochrotaenia jorm. nov. (133 d) from Loja 

 minerva. in Ecuador this yellow band is broad and terminates broadly at the costa; — in minerva Fldr. (133 e) 

 from the Rio Negro (Colombia) it is preserved as thin as a thread on the forewing, on the hindwing it has 

 leucodesma. almost disappeared; — in leucodesnia form. nov. (133 e) from the Rio Dagua (type in the Tring Museum) 

 sprucei. it is snow-white instead of yellow, in sprucei Bat. (= nigrescens Mencjel) (133 e) it is shaded by grey. West 

 i:<tturata. Colombia. In Colombian sprucei the basal part of both wings is beneath light silvery blue; in saturata 

 Thm. (133 e) from Ecuador, scarcely differing above, the whole under surface is dusted with dark (on our 

 figure the two under surfaces of sprucei and ■mturata have been mixed up). Rather common.

S. pallas. This species resembles in different local forms almost all the forms of the preceding group 

 of Siseme, so that on the whole the typical pallas corresponds with lucilius or .spectanda, pomona with .spru- 

 cei, xantkogramma with ochrotaenia, albescens with leucodesma etc. All the pallas-f orms, however, are at 

 iKilla.-i. once distinguished by the border of the hindwing being distally not round, but rather drawn in. — pallas 

 Latr. (= aristoteles Stgr.) (133 c) is the form with a fusiform, in the middle broadly white median band; 

 anyu-stior. from Venezuela and North Colombia. — In atigustior form. nov. (133 c), from considerable altitudes (Monte 

 Tolima etc.) in Colombia, the median band is narrowed almost to one half, sometimes to one third. — 

 pomona. In pomona G. and .S'. (133 c) lying before me from the Rio Negro (Colombia) the band is shaded with grey. 

 xanthogram- — j^^^ xanthogramma Bat. (133 d) the median band is yolk-coloured, from the Rio-Negro in Colombia. — 

 atrytone. atrytonc Thm. (133 d) exhibits half the median band yellow (Bolivia) or ochreous with a whitish brightening 

 (tlhenren.'^. in the middle (Pozuzo, Peru), sometimes also nearly all white (albescens Stich.) from Ecuador and the neigh- 

 bouring districts. — With respect to the width and pointedness of the fusiform median band, the species 

 at every habitat exhibits certain, quite constant peculiarities. The butterflies are common, 

 jirio-orfc.v. S. neurodes i^Wr. (133 c). Very similar to the preceding species; smaller, recognizable by the broader 



red anal band and by the much more intense and longer white rays in the distal part of the under surface 

 of the hindwings. I know this form only from Peru. — From Bolivia and Colombia, as well as from the 

 Pozuzo (Peru) a more dark slate-blue form is known with the anal part of the hindwing being more ex- 

 cai(diiiis. tended and ending into a sharp tooth; to this form, caudalis Bat. (133c), however, there are transitions 

 found. — Common. 

 pedia.o. S. pedias G. (133 d) does not entirely belong to this genus and might form a connection with the An- 



cyluris-grouY). The total appearance reminds us of pallas, but the light patches, particularly beneath, show 

 a bright hyacinth-blue reflection; the small red anal band of the hindwing varies in shape and width. Before 

 me only from Bolivia; mostly from the Rio Songo. Apparently rare. 

 pxeu(h,pal- S. pseudopallas ircyw. (= hellotis Thm.) (133 b). Greatly resembles pallas, but the median band 



'««■ of the forewing is more bone-yellow, above not pointed, but broadly reaching the costa. Beneath in the 

 hyperion. distal part of the forewing instead of the band formed of rays a white transverse line. Peru. — In Hyperion 

 form. nov. (133 a) being only half as large, from Huayabamba, the median band is anteriorly greatly narrowed 

 and terminates behind in the middle of the hindwing. Not rare.

76. Genus: Dropaiiiila Rob. 



The genus is not closely allied to any other. The species described first was dealt with as Lemonias, but 

 RoBER combined its characteristics deviating from the LemoMww, already in 1892. From Ematurgimi to which 

 Stichel allies the genus the subcostal system deviates essentially, the neuration corresponds rather with 

 Siseme which, however, shows again a greater variabilitv of the veins, altough it undoubtedly represents
