THECLA. By Br. M. Draudt. 759 



Th. adunca sp. hoik (153 g) lying before me only in one C^: is undoubtedly closely allied to hi/hhi, though adiuwa. 

 it has remarkably narrow forewings with a rectangular apex and very long-stretched hindwings with a concave 

 costal margin and a long anal part being curved inwards. Above lustrous violettish-blue, on the forewings 

 also above the cell, the costal margin narrow, the distal margin broad black. Costal angle of the hindwing 

 broa.d blackish-brown, gradually tapering to the anal ape.x. Beneath the forewings are brownish-grey, with 

 red scales at the cell-end; far behind the middle a darker undulate transverse band interspersed with red scales, 

 extending as far as the lower median vein and being distally white-scaled like the outermost marginal area 

 in front of which there are red crescentiform spots. Hindwings of a purer grey, strewn with red scales, with two 

 strongly dentate red transverse lines and between them a red discal streak; the distal transverse line is distally 

 tinged in white, rumiing from the distal third of the ctistal nu\rgin in a straight direction as far as down to the 

 submedian fold close in front of the bordei' and then b'-nding round acute-angled to the proximal angle, as 

 it is the case in loxvrina. The marginal part is, ])articularl_y towards the costal margin, lighter whitish, on 

 the ends of the veins are thick black-red dots. Monte Tolima (('nlondiian f'ential Cordilleras at an altitude

 brown forewings which are dusted in a greenish bluish-grey in the V- The under surface is browner with but 

 one brown dentate line on the hindwings, behind it l)rightened up by reddish-white. Colombia. Peru. 



Th. tyrrius Brc. (I53f, g) is to be separated from the preceding by the light-brown oblong scent-spot Ihh-'ikh. 

 at the cell-end; above otherwise similar. Beneath brownish-grey strewn with dark-red scales, with the same 

 dentate line behind the middle and an obsolete row of moonspots in front of the border ; in the disc of the forewing, 

 as in the preceding, an opalescent blue stripe. Ecuador. 



Th. mishma Hew. (153f) has above brilliant metallic-blue wings with broad, blackish-brown distal mishnia. 

 margins. The under surface greatly resembles that of arria, more red-brown, the dentate line of the forewing 

 begins at the costal margin with an isolated spot, Colombia. 



Th. oxida Hew. (153f). ^Vings above deep violet, only the costal margin of the hindwing of a some- o.vidfi. 

 what purer blue with a very narrow scent-scale-stripe, along the upper cell-edge of the forewing. Fringes 

 blackish-grey. Beneath likewise marked very much like the preceding, darker brownish-grey, strewn with 

 red, the dentate lines more interrupted, not so coherent, in the ,3^ below the cell of the forewing opalescent blue.

Th. schausa Jones (153f). The ,^ is above black, the cell and submedian area metallic purple blue, .srhausa. 

 behind the cell with a small scent-sjiot, the anal angle of the hindwing tan-coloured, fringes grey. Under surface 

 more purple-brown, thickly strewn in red with red dentate lines, a red marginal band and a tan-coloured border; 

 the forehead is red, too. The $ is of a duller blue, «ith a In'oader black border. Brazil. (Castro, Sao Paulo.) 



Th, aurugo .S7;. nov. (153g) resembles o.viiht above l)y the deep violet colour, but it has no scent-scales mo-mjo. 

 along the subcostal, the distal margin is narrower black, the fringes orange-brownish. On the under surface the 

 wings are very conspicuously lemon-coloured, strewn with red scales, and with similar, though not no very 

 dentate transverse lines. Nearly the whole proximal margin of the forewings inclusive of the lower cell-half 

 is of an opalescent greyish-green colour, the abdomen beneath orange-brownish; the basal half of the ^Jroximal 

 margin of the hindwing is more greyish-brown. According to 2 JJ from Cuzco (Peru) from the Coll. Fa.ssl. 



Th, commodus Fklr. (153 g) to a certain degree approximates hyblti and especially aduncn. The comniodiis. 

 shape of the hindwings like in the latter. Above lustrous greenish-blue with very broad blackish-brown nuxrgins; 

 beginning from the distal half of the cell the blue colour warms into a deep metallic olive-green towards the 

 apex. Beneath the scheme of markings is likewise similar; on the hindwings the two dentate lines are separated 

 at the costal margin by a large, olive-greenish or yellowish triangular spot; the marginal area is olive-green 

 with small, purple-brown spots in front of the l)order in whitish-grey rings, being proximally mounted by 

 angular spots of the same colour. Colombia. 



Th. elongata Hew. (150 f) is likewise another specialisation of the same group. The blackish-brown lionyaln. 

 forewings are only l:)elow the cell strewn with metallic blue, at the cell-end is the hardly noticealile large black 

 scent-spot. Hindwings in the inner-marginal half somewhat more extensively blue. Beneath blackish-brown, 

 at the proximal margin and border of the forewing lighter, almost whitish, with several, irregularly undulate, 

 dark lines. The hindwings appear marbled by densely strewn light scales and exhibit several very irregularly 

 dentate transverse lines. Marginal line distinctly black. From Ecuador and Bolivia. 



Th. bilix Ap. ?iov. (153 g) approximates mishma. Above lustrous metallic-blue with l)roa(l black hili.r. 

 margins and apex, costa and fringes red-brown; hindwing with a long-extended anal angle and equally long 

 tail on the lower median vein. Beneath greyish-brown, strewn with red, with transverse lines consisting of 

 incoherent lunular spots, on the forewings 2 close in front of the border, on the hindv\ing 3 ecpially distant from 

 each other; each wing exhibits red discal transverse streaks; the inner-marginal blue is absent. Described 

 according to a J from the Rio Aguaca \'alley (Colombia) from the Coll. Fas.sl.

 Th. goleta Hew. (154e) is immediately recognizable by the peculiar shape of the wings with the (jolctd. 

 deep concave indenture between the median and radial veins of the forewing, and by the long-stretched anal
