512 ADELPHA. By H. Frfhstorfer. 



lara. A. lara replaces A. isis in Venezuela and the region of the Andes. It differs from the Brazilian 



isis chiefly by the absence of cellular red spots on the upper surface of the forewings, while the under surface 

 is recognizable by yellowish-brown cell-decorations instead of red ones. Two territorial forms: lara Hetv. 

 with a regular red ti'ansverse band on the forewings which is distally bent out convex hardly perceivable. The 

 under surface more violet, always without the black median band in the anal part of the hindwings. The 

 9 is only slightly larger than the ^, 9 somewhat lighter brown and also beneath somewhat paler than the 

 mainns. ,^. Venezuela. — mainas subsp. nov. (108 f as lara) is found from Colombia to Bolivia along the range of the 

 Andes. (^ : the red band distally more irregular. The under surface with a pale oblique band being, however, 

 magnificently rouged at the costal and anal end. The 5, of which I examined a specimen from the Rio 

 Negro, stands in the same relationship to the (J as the $ of lara. Clasping organs of about the same struc- 

 ture as in isis. Valve set with just as long bristles, but the clunicula more uniform with a broader peri- 

 phery. Point of the uncus without medial thickening. Valve more slender in its outer parts. The differentia- 

 tion is, however, still rudimentary and confirms much rather that A. lara belongs to i.sis than that they are 

 specifically different. Median band of the hindwings only streak-like, but always distinct. Peru, Bolivia; 

 an intermediate form also in Ecuador, nowheres rare. 



fi) Two subcostal veins before the eell-apex. 

 A. epione, the only species of the whole genus with a pure white transverse band of the fore- 

 aijiUa. wings. Two areal forms: agiWa Fruh.st. (lOSe as epione) occurs along the Andes from Colombia to Bolivia from 

 where the figured specimen originates. The width of the brown median band on the under surface of the 

 epione. hindwings varies regardless of the localit_y. — epione Godt. *), a smaller form with much narrower white 

 band on the forewings and prominent white small anteterminal spots on the under surface of the hindwings. 

 In my collection from Espiritu Santo, but occurring also near Rio de Janeiro; in Staitdingbrs collection 

 there are ^(^ from Casa Branca in the State of Parana. 

 epoiihia. A. eponina Stgr. An interesting species the white band of which begins to dissolve already towards 



the costal margin and to change into greyish-brown. Under surface especially characteristic by vast greyish- 

 vohipis. violet jjarts. Colombia, Cauca Valley. — volupis subsp. nov. is a magnificent form from the Rio Aquaca Vallej', 

 from an altitude of 2000 m in the Western Cordilleras of Colombia, with considerably narrowed white deco- 

 rative band on the forewings being extended only as far as to the posterior median where it disappears already. 

 Also on the under surface the white bands begin to recede what is especially recognizable by the reduction of 

 the white median band. 

 hypseiior. A. hypsenor Godm. and Salv. (108 f misprinted as hypsina) has so far been known for certain only 



from the Province of Antioquia, the Cauca Valley in Colombia. Fassl discovered it at an altitude of 2000 m 

 in the Rio Aquaca Valley (Western Cordilleras). The under surface resembles that of A. mesentina (108 e) 

 except that the red spots are replaced by yellowish-brown ones. The $ is larger, on both the surfaces lighter 

 brown than the cJ, with a somewhat broader white oblique band, hyp.senor already forms the transition to 

 the group with ochre-yellow bands on the forewings to which 

 sophax. A. zalmona belongs. There are two local forms to be mentioned; sophax Godm. and Salv. (108 d) 



from Costa Rica, Panama and some districts of Colombia. Under surface with narrow greyish-violet subbasal 

 zalmona. band of the forewings, and zalmona Heir, from Colombia without exact habitat, with considerably broader 

 band of the hindwings. 



A. melanthe, a magnificent easily recognizable species with nearly double as broad dark chrome- 



mclanlhe. yellow belt of the forewings, as sophax. Three geographical races: melanthe Bates with two white dots in the 



forewing-cell. Central America from Mexico to Panama in sparsely timbered woods at an altitude of, GOO to 



melanippc. l(i(»0 ni. — nielanippe Godm. and Salv. with narrowed and darkened yellowish band of the forewings. Colombia. 



spriireana. — spruccana Bat. with still more narrowed median band and, like ■nielanippe, without white cellular dots on 



the forewings. Ecuador. Clasping organs still entirely of the type of Adelpha isis-lara, valve basally somewhat 



narrower, ventrally less convex prominent, clunicula growing somewhat more slender towards above. Point 



of the penis more sharply curved. 



A. mesentina, a rather rare, very characteristic species with reddish-ochreous area of the forewings. 



thanclia. Only two ramifications with not very abrupt joartings: chancha Stgr. (108 e as mesentina) with broadened black 



longitudinal bands on both the surfaces of the hindwings. Peru. — The name-type is based on a specimen 



me-'trntlna. with a shortened reddish-brown band on the forewing: mesentina Cr. **) being beneath somewhat paler than 



the Andine form. Cayenne, Surinam. Amazon. Also from A'enezuela and Ecuador, in the Tring-Museum. 



B) Group of Series Heterochroa. 



A. irmina, a common species of the ochreous group of the great Heterochroa-iiecUon of the w hole genus. 



Relatively large with steep median band of the forewings. Under surface resembling that of A. irma, but with 



innhm. vvhite drops on the hindwings. Three geographical branchings: irmina Dbl. (108 f) varying according to the 



*) Valve basin-shaped, basally veiiti-ally expaudeii. ai-iiii'd with I spines. Chinicula black, pyramidal, vi^ry lii^h i 

 valve somewhat more slender in (icjllUi.. 



**) Valve boldly shaped. Veutrally set with 12 to 15 teeth, besides with a dorsal protuberance, chuiicula with 

 exti-aordinarilv broad base.
