AMBLYGONIA; AMARYNTHIS; EXOPLISIA; NELONE. By Dr. A. Seitz. 691 



66. Genus : Amblyj^ouia Fldr. 



After eliminating the species placed here by Felder, the name of the genus remains for the following 

 species. A tiny, square-built butterfly with a robust body and broad wings traversed by a yellow band; 

 Silvery lines are absent ; remarkable are 4 larger spots of the wings occurring in the $ — a form of the sexual 

 dimorphism being otherwise not common. 



A. amarynthina i^Mr. (= monogramma Bat., barzanes Hew., $ = quatrinotata Btlr.) (132 h). A small amaryn- 

 species. Blackish brown with a small orange-yellow, above often darkened median band, the much rarer 5 ^^wa. 



with one light yellowish-white clot in front of the middle of the distal margin on each wing. The ^^ are 

 not rare in almost the whole of South America, from Argentina to Colombia. The band varies considerably 

 in width and intensity of colouring, but it is in the <^ beneath always broader and brighter than above. 



67. Genus: Amaryutliis Hb7h. 



This genus has likewise only one, very singularly coloured species. Larger than the preceding species, 

 less robustly built, the wings very delicate; the veins deviate from those of the Amblygonia only by the 

 3rd subcostal vein not rising immediately before the cell-end, but immediately behind it. The species forming 

 this genus is very widely distributed. 



A. meneria Cr. (132 f). Black with a narrow red transverse band and sparse light, small dots; meneria. 

 in the cell of the forewing a red cuneiform streak, behind it a small red spot. ■ — In superior form. nov. (132 g) svperior. 

 flying near Humayta and lying before me in great numbers, the red band, particularly beneath, is more than 

 twice as broad and the dots are of a bright white, larger and increased; the form itself is very large. ■ — In 

 contrast with it, ab. maecenas F. (132 g) is without any small white dots. A form being especially in the fe- maecenas. 

 male sex extremely broad-banded and rather small originates from Nouveau-Chantier in French Guianais 

 coccitincta form. nov. (132 g), but already in Cayenne there occur again narrow-banded specimens. This charac- coccUuida. 

 ter is local, but not temporal, for I possess homogeneous specimens from April, October, December and Fe- 

 bruary. — stenogramma Stick. (132 g) contrasts with coccitincta by the red band being here as thin as a stenogram- 

 thread, even extinct in some places; from Ecuador, where, however, there occur also specimens hardlj' '""■ 



distinguishable from Peruvians. — tnicalia Cr. (132 f) is the common form living in almost the whole northern micalia. 

 part of South America, with a distinct, unabridged, but moderately broad band, in which there is in the cell- 

 end a small red spot isolated from the basal streak, which is confluent with the latter in ab. conflata Stich. conilaia. 

 meneria ist not so common as we might be induced to believe according to the numerous specimens in the 

 collections (before me are about 300) ; but it is one of the most conspicuous butterflies, being equally keenly 

 collected by European and native collectors. — I call the reader's attention to a strange coincidence: at 

 the same place ((Humayta on the Amazon), where A. meneria exhibits a broad, coloured band and a conspi- 

 cuously copious white dotting, the same symptom occurs also in another, but very distantly allied Erycinidae 

 (Eiodina lysippus L.) *). 



68. Genus: H^xoplisia G. and 8. 



This genus was formerly united with the preceding to which it is very closely allied, but its members 

 have somewhat shorter palpi. Certainly the total appearance greatly deviates from that of the AmaryntMs 

 by the entirely different colouring, but the anatomical structure makes it doubtful -^^hether ExopUsia is to 

 be separated from Amarynthis. From the following Nelone, ExopUsia is separated by the finer clubs of the 

 antennae, the appressed palpi, the shape of the wings, particularly the stretched costa of the forewing, the 

 fringes at the anal part of the hindwing being prolonged to a regular beard. Only one species. 



E. hypochalybe Fldr. (= praxithea Bsd.) (132 g). Above dark brown, beneath of a lustrous light blue, hypocha- 

 with black veins; on both surfaces numerous straight black transverse stripes. Reported from Central America 'i/^^'- 



to Peru. — muscolor Weeks (132 h) differs scarcely above, beneath, however, the distal transverse stripe run- nna-color. 

 ning parallel to the border of the forewing is absent.'^' Bolivia.* Not rare. 



69. Genus: J^elone Bsd. 



Distinguished from the ExopUsia by the projecting palpi, the more strongly clubbed antennae, the 

 quite different shape of the forewings exhibiting an arched distal margin, a curved border, a rounded anal 

 angle and a longer proximal margin, and by the absence of a regular beard at the border of the hmdwmg. 

 where only longer fringes are formed; the marking is quite different, the veins exhibit metallic rays before 

 their termination, the fringes are speclded. As the species are not congeneric with hypochalybe, this being, 



*) This symptom which has pi-esuniabh' nothing to do with mimicry, is denoted in the zoology as a local chaiactcr 

 of variation.
