756 THECLA. By Dr. M. Dbaudt. 



23. Platyptera- Group (Micandra Sckaiz). 



platyptera. Th. platyptera Fldr. (153 c) according to our present conception, is not to be separated from Thecla, 



regarding the genus. In the scheme of markings beneath it offers close resemblances to cadnms (149 c) and 

 may, therefore, be placed here. Above like ion (149 a), also with a similar large scent-spot reaching further 

 towards the base only in the cell. Beneath the forewing is of a brilliant blue, the proximal margin whitish- 

 grey, the costal margin and distal margin narrowly black. Hindwings without tails, black with 4 very 

 fine dentate lines consisting of single, scattered bluish-white scales; in front of the border are somewhat larger 

 double-spots. Colombia, Venezuela, Peru. 

 circinaia. Th. circinata Hew. (149 d) we also place here, as it is beneath marked exactly like thnaeus (149 c), 



although it looks above quite differently: deep ultramarine-blue, with a black margin occupying almost half 

 the forewing, the mitailed hindwings are only at the costal-marginal angle somewhat broader black, the distal 

 margin being narrow. Costal margin whitish-grey, below it a large, dark blue scent-spot strewn with black. 

 Beneath the ground-colour is blackish-grey, the lines light-blue; the forewing exhibits an opalescent blue discal 

 spot. Colombia, Bolivia. The species at the same time shows close relations with the following group. 

 sapko. Xh. sapho Sfg?-. (146 c) has been placed to Micavdra by the author without the reasons being 



mentioned, but it seems much rather to be a Theorema. It was described from Colombia and has hitherto appa- 

 rently not been found any more. 



24. Eronos-Group. 



erorws. Th. eronos Drc. (153 c) is above magnificently peacock-blue with a darker apical third of the fore- 



wing, without a scent-spot and tails ; the lower median vein of the hindwing is set with long hair. Beneath, the 

 forewing is in the disc of an extensive opalescent blue, the hindwing almost black, strewn with scales of a greenish 

 reflection, and with 2 similar, undulated, quite indistinct transverse lines. Colombia. 



trochus. Th. trochus Brc. (153 c) is very similar, but above brilliantly green and beneath on the hindwings 



lighter with more distinct light transverse lines and a red, black-pupilled spot between the median veins. On 

 the forewings the opalescent-blue colour is confined to the jiart round the median veins behind the cell. Colombia 

 (Pacho, Muzo, Rio Aguaca Valley). 



25. Thara- Group. 



ihara. Th. thara Hew. (= ivelia Gosse) (153 c). The (J is above magnificently light ultramarine-blue, the 



$ somewhat more greenish \\'ith a bread black apex of the fore\\'ing. Beneath brownish-grey with 2 rows of 

 white, proximally darker-bordered lunular spots behind the middle, both wings with a white discal streak, the 

 hindwings towards the base below the costal margin with an additional white streak-spot; the proximal white 

 line forms a pointed W at the proximal margin of the hindwing, the surroundings of the distal line are here 

 more or less strewn with bluish ; anal spot black, above bordered by white, betM'een the tails a black spot bordered 

 above by orange. Brazil (Rio, Sta. Catharina). 



eunus. Th. eunus G. & S. (153 d) is coloured and marked just the same on both surfaces and has also 



beneath the same black scent-spot at the base of the forewing below the median, but the costal margin of the 

 hindwing is bent more convex and on the upper surface is a lustrously polished scent-spot like in barajo (149 e) 

 below the costal margin at the base of the hindwing. From Guatemala to Colombia (Muzo). 



26. Gigantea-Group. 



gigantea. Th. gigantea Hew. (153 d). I know only from Hewitsox's description and figure. Above light-blue 



with bro\\iiish -black veins and margms and a very large discal spot. Beneath reddish-broAvn with cell-spots 

 and dentate lines which are bordered by white on the forewings only distallj^, on the hindwings on both sides; 

 in front of the border is yet a brownish, proximally white-bordered macular band, and at the anal angle 2 black 

 spots being bordered above by red-yellow. Para. 



27. Linus-Group {Araivacus Kaye). 



limis. Th. linus F. (= ImcusGor/f., aetolus C?-., am.e]ia£^6s^.) (150 c) is above white with the marking showing 



through from beneath, a broad blackish-brown distal margin and 2 similar lines in front of the border of the 

 hindwing. The ^ exhibits, below and behind the cell, a large, roundish scent-spot which mostly sends forth 

 yet a tiny spot into the lower cell-corner and which, in contrast with the following specie?, always ends roundish 

 outside on the lower median .-ein. Beneath there are 5 black stripes being convergent towards the proximal 

 angle on the hmdwing; the proximal and distal margins are orange, the latter colour bordered by the fifth 

 black stripe running near and parallel to the distal margin, the two next ones approximating each other. Anal 

 angle black with 4 white dots. Colombia, Venezuela. Amazon, Bolivia.
