528 ADELPHA. By H. Frt'hstorfer. 



roih<^rh;i<Vi. A, rotiischildi spec. nov. (106 a). ,^ length of forewiiigs 33 mm. Orouud-colom- jet-black with light 



brown basal part and longitudinal bands of the same colour in the cellule of the forewings and in the median 

 and distal region of the hindwings. Forewing with a band being very proximally bent up beyond the cellule 

 and composed of 8 dark orange-yellow, roundish, medium-sized spots being pcripherically diffuse. Before the 

 apex of the cell there are three more small spots of the same colour, those at the costal margin being elongate 

 and very thin, the two lower ones of a square shape. Under surface: ground-cohiur dark reddish-brown. Base 

 of the forewing, one median band, one post-discal band and a row of 6 submarginal spots light bluish-grey. 

 The whole surface of the hindwings except the reddish-btown distal region likewise light grey. The costal margin, 

 one subbasal, 2 median and 2 submarginal bands reddish-brown. The interior reddish-brown submarginal band 

 on both sides bordered in black. In the anal angle there are 2 black dots between the posterior median and 

 the submedian. The distal margin jet-black, at the cell-apex of the forewings two grey points and above 

 there are those 2 whitish square spots that are coloured in dark red on the upper surface. The under surface 

 resembles somewhat that of .4. salmoneus Btlr. Ecuador, Paramba, from an altitude of 3500 feet, from 

 May 1897. Type in the Tring-Museum. 

 ii-dcid. A. tracta Btlr. (109c) is to be found in every parcel from the volcano Chiriqui where it inhabits 



altitudes of 3 — 4000 feet. The species is besides known only from Costa Rica where it is met at the volcano 

 Irazu even in altitudes of 6 — 7000 feet. The character of its markings nuist be considered to be just as 

 isolated as its occurrence. Upper surface cocoa-brown with a lighter brown middle-zone and two submarginal 

 stripes of the hindwings of the same colour. The forewings are traversed by a band-like united row of pale 

 ochre-yellow, distally diffuse spots. Under surface yellowish-grey with reddish-brown longitudinal bands. 

 Both the wings have besides a faded pale-yellow- median stripe. The clasping-organs are noticeable by a low 

 dorsal appendage of the valve rising tuberously, but not in the shape of a tooth. Valve is besides distally suji- 

 plied with a remarkably long tooth on the top. Uncus robust, resembling that of the A. serpa-group. 



jriirrria. A. leuccria Druce (109 c), originally described from Guatemala, occurring to the south as far as Panama 



and to the north as far as Mexico, differs somewhat according to the season. Thus, the Tring Museum possesses 

 a (J from Cuesta de Misantla from June 1896 with all the characters of a dry-period form, lighter and 

 broader white bands on the under surface of the wings. The upper surface differs from all the known .species 

 (with the sole exception of A. malea Fldr.) by a broad ochreous median area traversing both the wings, but 

 growing narrower anteriorly from the cell-apex. Distal to this band only three, relatively large preapical spots 

 of the same colour as the median bands. Anal spot of the hindwings uncommonly broad, but isolated. Under 

 surface somewhat reminding us of A. sichaeus irisa (106 b) with white median stripes through both the wings 

 and violet prominent submarginal spots. 

 YiuiU'fi. A. malea Fldr. (109 c) possibly replaces A. huceria in Colombia, though the under surface is so dif- 



ferent that it can certainly be considered a species of its own. Both the wings traversed by a costally broader 

 ochreous band confluent with the anal spot of the hindwings. The under surface with a more than again as 

 broad faded yellowish-white median zone, compared with A. leuceria. Basal spotting of both the wings, however, 



jiiKiiiiii. agrees with that of ^4. leuceria. Venezuela, Colombia, very rare, only 1 ,^ in my collection. — juanna Srn. is 

 a local form described from Valdivia in C'olombia; of a greater habitus than leuceria and malea, Init not devia- 

 ting from malea in the marking. 



rihri,!,!. A, ethelda Hew. (109 d). Upper surface dark brown. Both the wings are traversed by a joint orange 



band being slightly angled beyond the cellule and beginning to dissolve into single spots above as well as 

 beneath. The under surface entirely resembles that of A. attica, but the median zone of the forewings is more 

 band-like and just like those of the hindwings pale yellowish, instead of white. The subbasal black stripes 

 somewhat weaker. Described from Quito in Ecuador, but pretty surely not originating from this capital situated 

 almost 3000 m above the level of the sea, but presumably collected in the hot valleys of that country in an 

 altitude of not more than 1500 or 1800 m. Very rare, only the type known. 



<U'iiiiiiih(i. A. demialba Btlr. (109 d) a characteristic, cjuite isolated species, which is also locally extremely 



confined and has hitherto been proved only from Costa Rica and Panama, demialba is considered an alpine 

 butterfly flying in open spaces of the woods in altitudes of 4 to 5000 feet and being very difficult to catch. 

 Upper surface bluish grey with black bands. Forewings distally, from the cell-apex, decorated with 2 rows 

 of submarginal white spots, besides a series of ante-terminal stripes traverses the forewing, and bej-ond the 

 cellule there are three strigae embedded. Under surface bluish grey with brown bands changing off with \i(il(( 

 stripes in the cell of the forewings and in the intericu' part of the hindwings. 



A. attica initiates an interesting and prominent small group of species found extremely seldom in the 

 collections. The few species belonging to this group exhibit the magnificent and singular markings of the under 

 surface of the A. serpi-gvo\x\i, but are still anatomically closely allied to the .4. iphicla-gYo\i\} by the valve being 

 (crowned by an appendage. .4. attica itself has the relatively broad, knife-shaped uncus of the A. .scz/w-gioui): 

 the valve itself is distinguished by being entirely unarnu'd. The (huucula. is nearer to the sternit than in flic
