5-21 ADELPHA. By H. Fklmiwtokfku. 



ahiii. A. abia Heir. (109 a) liithcrto known only from Rio de Janeiro, may be con.sidered one of tlie com- 



monest Adelphes of Southern Brazil occurring also in Argentina and Paraguay. It very probably leplace.s 

 A. thessalia in Brazil and the neighbouring states. The clasping-organs are, as regards the valves, but slightly 

 differing, but the uncus of abia seems to be more robust and shorter, the scaphium and tJie saccus broader. The 

 valve of abia is somewhat more slender with a more bulky appendage of the very high clunicula. Accor- 

 ding to the season the under surface of the butterfly may be striped in vivid light cocoa-brown or nearly 

 whitish, with faded bands. Upjjer surface very similar to A. iphida indefectn (107e), though with a more 

 pointed leddish-yellow area of the forewings. Specimens from Rio Grande do .Sul are beneath almost 

 entirely whitish-grey. 



A, basiloides resembles above A. iphicleola (107 d), except that the white median band penetrates 



the cell. The under surface is darker blackish-grey, the brown longitudinal bands are somewhat more tightened 



than in A. iphida. The range of the .species is very limited: Central America, and besides only Colombia ajid

liidia. The $ has sometimes a second streak-like spot before the apex of the cellule of the forewings. — lydia 



cdi'lia. Btlr. is a race described from Honduras that has remained unknown to nie in nature. — caelia subsp. nov. has 



more roundish contours and a greater size of the wings than basiloides. Median band broader, the yellowish 



lulu-iUa. parts more insignificant than in specimens of a more northern origin. Colombia, rare. — lativitta Sfgr. l)eats 



even caelia in the width of the white median area. Venezuela. 



A. pithys, a rare species hitherto known only from Guatemala, has rcc'cntly been discovered also in 

 Mexico. Upper surface as in A. ipJiicla, only with the yellowish subapical Ijand of the forewings being posteriorly 



ij'illii/s. prolonged, relatively narrow and projecting as far as to the costal margin, pithys i^ates (109 a) differs beneatli 

 from the forms of the iphida-gvoup by the transcellular whitish violet maculae or strigae being replaced by 

 a faded loam-coloured band. Basal zone of the hindwings extensively whitish violet, only with fine reddish- 

 brown lines instead of strong brown stripes as in A. iphida. Guatemala, very rare, in altitudes from :2000 



viidcna. to 5000 feet. — vodena subsp. nov. Habitus larger than that of the Central American race, the median band 

 of the hindwings considerably narrower. Under surface throTighout darker, the hindwings Avith jjrominent red- 

 dish-brown distal delimitation of the A^hite discal band. Guerrero (Mexico). 



(Iiinijsa. A. donysa Hew. (= roela Bsd.) occurs in Mexico and Guatemala beside .4. pithys, likewise very rare, 



ascending from the lowland up to altitudes of 2000 m. The species resembles above the common A. abia 

 Hew. (109 a) from Rio de Janeiro, is larger than A. pithys with much narrower white median band. Under 

 surface darker, the base of the hindwings more grey than violet. Godman found a J at the volcano Fuego 

 in Guatemala in an altitude of 7000 feet. 



A. abyia, a species being very rarely found in the collections, resembling above ^4. pithys, but im- 

 mediately distinguishable from it by the long-stretched, sharply serrated hindwings, which exhibit an un- 

 commonly large reddish-yellow anal spot. The subapical spot of the forewings prolonged to the costal margin

 form to be identical with A. celerio Bates, but abylina is still less allied with A. celerio than with A. ipliic- 

 la L. Habitat of abylina unknown, presumably one of the West Indies. 



A. gelania, a collective species from the West Indies; upper surface brown with a narrow white 

 or yellow median band extending as far as to the anterior radial. Before the apex another yellowish spot.

 known, one of the Antilles. The statement of Doubleday. however, that the species is said to occur in 

 Mexico, has hitherto not been confirmed. 



A, lerna. A magnificent species combining the marks of the A. iphida-gvoui'), bj- the scheme of 

 markings on the upper surface, with those of the A. eroiia-group, by the ojjulent decoration of the under 

 surface. According to the habitat, the size and width of the white bands and yellowish red spots of the upper 

 surface are variable, whereas the under surface changes its tints less according to the locality than to the season. 

 Like in A. erotia, we notice in the dry period predominantly yellow bands, in the wet period preponderantlj' 

 intensive reddish-brown bands, lerna occurs from Central America to Bolivia, and as a rarity in the Amazon 

 district and jjarts of Guiana. Anatomically A. lerna has the same form of the uncus as A. erotia, while the valve 

 being distally extremely slender and turned down with the di.stal end in the shape of a beak, shows no rela- 

 tions whatever to the group of A. erotia and A. iphida, but occurs quite isolated. Clunicula has the shape of
