DYSMATHIA. By Dr. A. Seitz. 717 



of ion, but without the rusty reel in the apex and the cloud below the costa, but dotted in black and with a 

 black subniarginal band. Amazon. — Tlie species is not rare. 



Th. clotho *S7u7/. (13s b). This species not lying before me is based on a single 2; the black upper clollin. 

 surface is interspersed witii diverse light markings some of which are of a blue reflection. We figure the type 

 in the Berlin Museum, from Peru. Under surface greyish-yellow, dotted in brown; in front of the liorder lighter 

 with a series of dark longitudinal spots. 



Th. feisina Heir. (138 a, as felina). Sepia-brown, the distal part of the hindwing dull white. Under Msina. 

 surface quite whitish, only the apex of the forewing darkened. Above darker markings, beneath dotted in 

 blackish-brown. In the j" the white of the hindwing has a very faint bluish lustre. South Brazil. This species 

 is rarer. 



Th. pretus Cr. (138 c). Above black with golden-green undulate and dentate markings. Under sur- i>n/i>s. 

 face diity greyish-brown, with whitish and dark red-brown markings. East Brazil. — Colombian specimens 

 exhibit duller green markings and have a yellow under surface being only in the $ more copiously marked 

 in dark. — picta G. d- S. { 138 d) has a much more brightly lustrous, but more bluish-green marking of the upper iiirla. 

 surface, the under surface being more cojiiously decorated with whitish squares. Central America; Bolivia. 

 The $ is above like the ^, also of the same lustre, but it is larger. The butterflies are like all the Tharoj^s fond 

 of the open country, not of the woods. 



Th. menander Cr. (= petronius Godt.) (138 b). Above very difficult to distinguish from the follow- mciiamler. 

 ing species, but easily recognizable by the grey under surface exhibiting across the centre of the wings a 

 somewhat dentate, brown shade projecting under the cell-end towards the base. Northern part of South 

 America. 



Th. nitida Btlr. (138 c) is the name of greenish-blue specimens with few dark spots above. According iiitith,. 

 to StiCHEL they originate from South Brazil, though the specimens from there mostly have a violet and not 

 green reflection. — thallus Stic/i. is also said to have ,, often" a greenish-blue ground-colour; moreover, the llitillus. 

 black in the apical part of the wings being reduced, it exhibits more distinctly the dark marking of it. As 

 its patria the western part of the northern districts of South America is stated, though tlie forms are presumably 

 difficult to sejjarate geographically. 



Th. coruscans Btlr. (143 e). Above very similar to the preceding and like there it is sometimes smooth rornKcans. 

 and bright as a mirror, sometimes very much black-spotted, with a blue, green or purple glossy upper surface. 

 Easily distinguishable by the under surface being grey, at the border darker and the disc of both wings being 

 rather uniformly covered with greyish-brown dots and comma-stripes. Of the small marginal spots those below 

 the apex and in the anal part of the hindwing often are particularly bright. Amazon, Bolivia. Common. 



Th. purpurata G. d: S. (138 c). Above blue, less spotted, in the anal part of the hindwing 3 dark nuxcular iitn-pitnita. 

 bands above each other. Under surface yellowish-brown with whitish dusting and chestnut-brown marking. 

 Central America. 



Th. glaucoma Hbn. G. ( 138 b). Somewhat like the preceding species, but the hindwings in the ^ almost i/laiiaoaa. 

 without any markings, except the broad dark margin; most characteristic is the under surface exhibiting on the 

 forewing large, on the hindwing small ringed eye-spots in front of the border. Brazil, rarer. 



Th. splendida Btlr. Larger, the (J with a very pointed apex of the forewing and a long-stretched anal sjilvudUia. 

 part of the hindwing. The black spots are arranged in 3 or 4 rows on the metallic bluish-green upper surface. 

 The $ has on the forewing, above the blackish-brown disc, dispersed metallic bluish-green patches; in the hind- 

 wing particularly the costal part is of a bright light-blue. Para. — superba Bat. (143 c) from the Amazon is .siiprrh,!. 

 presesumably scarcely a different species; the ^ has more rounded hindwings, above of a bright metallic green, 

 in the disc of the forewing and the costal part of the hindwing of a pure cyan-blue; beneath the ground-colour 

 is a rusty yellow. The $ has no more blue at all on the forewing; on the hindwing this is confined to 

 the costal part. Apparently very rare. 



94. Genus: ]>^'»«niatliia Bat. 



Mostly attached to the preceding genus, but of a considerably punier structure, the wings more delicate, 

 the forewings very broad, the antennae shorter. Only 3 or 4 species are known from the Amazon and Guiana. 

 The butterflies seem to be rare. 



D. portia Bat. (138 a). The very broad wings above dark-brown with copious black spots arranged purfia. 

 in rows; tiie inner-marginal part of the forewing and the whole hindwings are above of a delicate violettish-blue 

 lustre, though not reflecting as in the Tharops. Under surface dark yellowish-brown, the marking similar to 

 that of above, the dark spots smaller. Guiana and Lower Amazon. — glaucogonia Stick, is somewhat smaller, ,ji(,,in.</o,ii,i. 

 the small dark spots above partly covered up by small blackish clouds, the marginal area of the wings lighter 

 blue; Guiana. 



D. cindra Stgr. (138 a). .\bove quite pale sky-blue with irregular black .■^treak-markings. Under sur- rin'lm. 

 face still lighter, with a dark-shaded anal part of tlie liindwing. Twice as large as the preceding species. Lower 

 Amazon.
