57. Gargara- Group. 



Th. gargara Hew. (155 a) is a smaller species which is difficult to range. The $ is blackish-brown rjargara. 

 above, towards the base blue; beneath brownish-grey, the indistinct postdiscal band darker brown, the .space 

 behind more red-brown; on the hindwing there is behind the dentate, dark-brown postdiscal a broad, lilac- 

 white band; the two small anal spots are bordered upwards by orange, then by yellow. Amazon. 



58. Ocrisia-Group. 



Th. ocrisia Hew. (= peruviana Erscli.) (152 b) is above blackish-brown, on the forewing towards ocrisia. 

 the proximal margin with a slight steel-blue reflection and near the base a large, round, brown scent-spot embed- 

 ded in a slate-grey circumscription like an eye. The hindwing is in a very variable extension strewn with metallic- 

 blue, mostly only in the inner-marginal half; there are also some blue antemarginal crescentiform spots. — 

 In case the blue disappears altogether, we hav^e zora Hew. before us. — Beneath likewise blackish-brown, fore- zora. 

 wing at the proximal margin whitish-grey, at the apex yellowish-brown, marbled with very irregidar and indis- 

 tinct markings, between the median veins a small orange spot. Very widely distributed from Mexico through 

 the whole of Central America as far as Peru, Bolivia, the Amazon, and Paraguay. 



Th. ocrida Hew. (152 a) is above similar, the cj is more blue, also on the forewings, the scent- ocrida. 

 spot proximally dark-browii, distally black; the $ unicolorously brown. Beneath very easily recognizable by 

 the yellow anal angle of the hindwing, in the $ the whole distal margin is broad yellow. Colombia, Amazon. 



Th. arpoxida sp. nov. (155 a) connects ocrida with avpoxais; shape and colourmg above as in the arpoxida. 

 former, cyanean-blue with a broad black apex and costal margin, also the scent-spot is the same. Beneath 

 dark-brown, lighter marbled, like ocrisia, but with the silvery-blue linear markings of arpoxais, also parallel 

 to the base of the costal margin there is one like it. Described according to 1 rj from the Rio Songo (Bolivia) 

 from the Coll. Fa.ssl. 



59. Thales-Gi'oup. 



Th. thales F. (= thrasyllus Hbn.) (155 a) is closely connected with the preceding group and has ihalcs. 

 the same shape of the wings. Above black, strewn with blue in a very variable extension, particularly in the 

 shape of spots before the distal margin of the hindv/ings, often also at the anal angle of the forewing. The small, 

 hardly visible scent-spot is dark-brown. Beneath purple-brown w-ith 5 bluish-white costal-marginal spots of 

 the forewings and fine blue linear markings, at the anal angle broadly strewn with greenish-golden. The 2 

 is above unicolorously brown. Distributed from Nicaragua to South Brazil and common. — thalesa Heic. is thaleaa. 

 presumably only an insignificant form in which the costal spots beneath are more intense, and the last is situate 

 closer to the apex. 



Th. arpoxais Godm. <fc Salv. (= clepsydra Drc.) (155 a) really belongs into a group of its own, arpo.vais. 

 but as it greatly resembles the preceding beneath, we range it here. Above magnificently cyaneous with a 

 broadly black apex and a large black spot filling up the distal half of the cell, the subco.stal above it set with 

 a silvery-grey scent-scale-stripe. Beneath purple-brown, at the apex of the forewing and at the anal angle 

 of the hindwing lighter brownish with blue markings and some green dusting at the anal angle. Panama to 

 Bolivia (Rio Songo). 



60. Besidia- Group. 



Th. besidia Hew. (152 h) is apparently a very rare, smaller species; the ^ above lustrous blue, besidia. 

 with a broadly black apex and a rather large, pear-shaped, dark scent-spot at the cell-end and behind it : the 

 $ is above duller and lighter blue with an extensive black margin and apex. Beneath reddish-brown with a 

 lilac reflection; there is a characteristic median band of the hindwing, being proximally broadh" tinged in red 

 (in the figure unfortunately greenish). Brazil, Colombia, Bolivia (Rio Songo, Fassl). 



Th. torris Drc. (155 a) closely allied to the preceding, above more indigo-blue, darker, beneath lighter ton-is. 

 greyish-brown without the purple tinge, both wings at the distal margins broadly whitish, the transverse bands 

 proximally not shaded by red, but by sepia-brown; the orange spot between the tails is absent. Rio Grande. 



Th. bagrada Hew. (152 k) differs from besidia by its duller lilac-blae colour being more confined; bagmda. 

 below the brownish-grey part of the scent-spot it another black one on the basfe of the median veins. Beneath 

 coloured like besidia; the proximally red median band of the hindwing begins at the costal margin with an 

 isolated spot dislodged outwards and being bordered by black and white on both sides. The 2 is above and 

 beneath lighter. Amazon. 



Th. obelus Drc. (152 k) approximates bagrada, is above more lustrous dark-blue with a smaller obelus. 

 round single scent-.spot at the cell-end, beneath darker red-brown, the median band of the hindwing more 

 coherent and more sinuous. The $ is above brown, beneath somewhat paler. Brazil.
