57. Gargara-Grou]). 



Th. gargara Heir. (15.5 a) is a smaller sjiccies which i^ diffitnilt to range. The $ is blackish-brown gargara. 

 above, towaids the base blue; beneath brownish-grey, the in'listinct 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 lioideied n])wards by orange, then by yelio.v. Amazon. 



58. Ocrisia-Group. 



Th. ocrisia Heir. (= peruviana Er.^rJi.) (152 b) is above blackish-brown, on the forewing towards nrrixin. 

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

 ded in a slate-grey cit-cumscription 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 sjjots. — 

 In case the blue disapjiears altogether, we lia^'e zora Heir, before us. — Beneath likewise blackish-brown, fore- ■■"ni. 

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

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

 the whole of Central America as t'ai' as Peru, Bolivia, the Amazon, and Paraguay. 



Th. ocrida Heir. (152 a) is above similar, the (^ is more blue, also on the forewings, the scent- "n-ida. 

 spot proximally dark-brown, distally black; the V unicolorously brown. Beneath very easily rccognizal)le by 

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



Th. arpoxida sp. no". (155 a) connects ocrida with arpoxais: shape and colouring above as in the iiriio.rida. 

 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 J from the Rio Songo (Bolivia) 

 from the Coll. Fassl. 



59. Thales-Group. 



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

 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 hindwings, often also at the anal angle of the forewing. The small, 

 hardly visible scent-spot is dark-brown. Beneath purjile-brown with 5 bluish-white costal-marginal spots of 

 the forewings and fine blue linear markings, at the anal angle broadly strewn with greenish-golden. The 9 

 is above unicolorously brown. Distributed from Nicaragua to South Brazil and common. — thalesa Heir, is thalcsa. 

 presumably only an insignificant form in whic'h tlie costal spots beneath are more intense, and the last is situate 

 closer to the apex. 



Th. arpoxais Godm. d- Salv. (= clepsydra Drc.) (155 a) really belongs into a group of its own, arpo.rais. 

 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 subcostal 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 l)lue mai'kings and some green dusting at the anal angle. Panama to 

 Bolivia (Rio Songo). 



60. Besidia-Group. 



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

 with a broadly black apex and a rathei' 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 broadly tinged in red 

 (in the figure unfortunately greenish). Brazil, Colombia, Bolivia (Rio Songo, Fa.s.sl). 



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

 greyish-brown witlKjut the purple tinge, both wings at the distal margins bioadly 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 Heir. (152 k) differs from be.sidin by its duller lilac-blue colour being more confined; hagmda. 

 below the browiiish-grey part of the scent-spot it another black one on the base 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 side-*. The '^ is above and 

 beneath lighter. Amazon. 



Th. obelus Drc. (152 k) approximates bagrada. is above more lustrous dark-blue with a smaller «?W(/.9. 

 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.
