5i(i ADELPHA. By H. Feuh.storfbk. 



median zone of the hindwiags on which we miss the reddish-brown anteterminal region of the upper surface, 

 airihui. so that collina looks again very similar to certain .4. alala. — aretina Fruhst. has still narrower white bands 



than collina. Both the forms are found in Ecuador. 

 aricia. A. aricia, a rare and magnificent species, apparently met only in Peru and Bolivia. Two territorial 



races, aricia Hetr. (108 a) of which we figure the characteristic under surface occurs in Bolivia. The upper 

 scrciiiUi. surface is adorned with a much broader reddish-yellow band than serenita .siibsp. nov. of w^iich we figure the 



upper surface by the name of aricia (108 a). Its under surface exhibits less bright reddish-brown bands and spots 



than the larger type from Bolivia. Habitat Peru. 



eiiiddiiiiia. A. epidamna Fldr., an extremely rare species of which but few specimens are known, one of them 



in Feuhstoefee's collection *). It is pretty sure that epidamna replaces the preceding species in Colombia. 

 It is, however, mentioned separately here, because the reddish-yellow submarginal band of the forewings is not 

 rectilinear as in A. aricia, but it turns out distally in the shape of a crescent between the radials and the 

 anterior median, and also disappears already at the central median. The under surface shows more prominent 

 black crescents distal to the reddish-brown median band, and purer white small submarginal spots. 



A. cocala commences the large group of species with yellowish-brown band of the forewings and white 

 area of the hindwings. The series of species then gradually turns into such forms in which a little white appears 

 on the forewings, and finally into forms where the yellowish-brown is isolated only to remain as a separated 

 apical spot. All the three combinations of colours have a relatively obtuse uncus and a valve with large 

 medial dorsal tooth the shape of which differs in the single species. The clasping-organs of A. cocala are charac- 

 terized by basally remarkably thickened uncus, valve short with strangely little developed dorsal appendage, 

 the end with sharp teeth, cocala is one of the most widely distributed Adelphes; we meet it from Honduras 

 lor::ae. to Bolivia and, on the Atlantic part of the Continent from Guiana to Sa. Catharina. — lorzae Bsd.. the nor- 

 thernmost branch of the race, is by mistake mentioned as A. vrraca by Godman, in the Biologia. from Hon- 

 lor;:'uia. duras in my collection and distributed as far as Panama, is distinguished by the broader white median band 

 of the hindwings and paler yellow middle area of the forewings. — lorzina .mbsp. nov. from Colombia has already 

 fufinn. decidedly narrowed yellowish-brown and white area on both the wings. — iuVmSi subs p. nova, another local 

 form from Colombia, shows a darker yellow part of the foiewings without any traces of a whitish hue at the 

 urnica. submedian. The white stripe of the hindwings less extensive than in lorzina. — urraca Fldr. (107 a) of which 

 we figure a $ specimen, is a luxuriant form beating the type from Surinam by broader yellow and white areas. 

 Under surface distinguished by most prominent white and violet spots. Upper Rio Negro, also at the proper 

 iirniciiKi. Upper Amazon, e. g. near Iquitos. — urracina subsp. nov. (lOtic), common in Peru and parts of Bolivia, lies 

 before me also from Mato-Grosso. The bands very nnich approach the type, but the band of the forewing 

 .■iiiapiini. appears more complete, the whole colouring darker. — suapura svhsp. nov. (106 c as sajmrua) from Venezuela 

 mnda. is a little form with considerably reduced yellow bands of the forew ings. From the Suapura River. — cocala 

 Cr., common in Cayenne and Surinam, has again som.ewhat broader i eddish-yellow bands of the forewings 

 rioUi. than suapura. — riola subsp. nov. (10(3 c as .j* instead of ?), from Rio de Janeiro and the State of Sao Paulo, 

 initiates the interesting Brazilian geographical forms; distinguished by the darkened faded reddish-brown 

 under surface with reduced greyish-violet spotting and most pronounced, anteriorly tapering white stripes 

 of the forewings. In riola, of which we figured a 5 from Rio de Janeiro, we notice in the (J and $ a white hue 

 cniiiiki. at the submedian of the upper surface of the forewings. which, in caninia subsp. nov. (106 b as riola) projects 

 into the yellow zone alrearly in the shape of a band. Sa. ('atharina and to the north as far as Sao Paulo, 

 didUi. while in didia subsp. nov. from Espiritu Santo the connection with cocala is restored by the white being 

 absent in the submedian zone, whereas the whole colouring of the under surface entirely resembles that of 

 the other species from Rio de Janeiro to Sa. Catharina. 



A. trinina is confounded in the collections with A. cocala. it has a delimited range and is found 

 only from Colombia to Ecuador beside A. cocala, as well as in Trinidad, trinina differs above by the reddish- 

 yellow preapical maculae of the forewings being either absent or hardly suggested, and beneath by the absence 

 of the white median band of the forewings being replaced by a faded loam-coloured band. The tegumen 

 has a considerably more pointed uncus, the valve remaining also more slender than in ^4. cocala. Besides the 

 medial dorsal tooth projects nearly double as strongly as in the vicarious type. The end of the valve only faintly 

 jnjia. spined. — fufia subsp. nov. (107 b) is renuxrkable by a dark ochreous, shaiply confined band of the forewings 

 mc(di)ia. and by white stripes reduced towards the anal angle. Colombia, appaiently not rare. — cocalina subsp. nov. 

 (106 b) smaller than the preceding one with a more uniform yellowish-brown zone and reduced white stri]ies 

 irhiiiKi.. of the forewings. Ecuador, Paramba, from an altitude of 1200 m. Type in the Tring-Museum. — trinina 

 Kaye was united with A. velia by its authoi-, and described and figured as ..4 . velia trinina in Trans. Ent. Soc. 

 1913, p. 555. The (^ differs from cocalina and fufia by broadened white median band of the hindwings.
