hindwing near the base; only one red eye-spot between the tails, between it and the black anal spot white 

 dusting. C'olombia: Rio Agiiaca Valley (F.as.sl). 



Th. aurorina sp. nov. (159 a) is undoubtedly the most magnificent species of this group, above almost aumrimi. 

 like (liirorn, radiantly light-blue with a large blackish-brown scent-spot filling up nearly the whole cell, and 

 a moderately broad black apex, the margins otherwise veiy narrow black. Beneath blackish-brown, at the proxi- 

 mal margin of the forewing somewhat lighter, marked like coelicolor (157 b), but the lines beautifully light-blue, 

 on the forewings bent uniformly; on the hindwings, in front of the border, indistinct darker spots in the space.s 

 between; only one red spot of the tail. Colombia: Caiion del Tolima; (^)uindiu Pass (Fa.s.sl). 



Th. thargelia Burin. (159 a) is closely allied to this group, though greatly deviating. Above plainly ihnriiclia. 

 greyish-brown, the o ^\ hh a blue disc, on the hindwing the black marginal line is proximally whitishly bordered 

 towards the anal. Beneath just as dark gieyish-brown with whitish postdiscals being proximally finely bordered 

 by black, on the hindwings ruiming straight from before the middle of the costal margin to the lower median 

 vein close in front of the border, in order to form towards the inner-margin a very high, pointed W: the sub- 

 marginals are far off from the border, broader black, proximally white, analwards there are behind it 2 large 

 orange, black-pupilled spots. The marginal line distinct, proxinially on the hindwings very fine white. Fringes 

 whitish. Abdomen beneath ochreous-yellow. Aigentina. 



Th. cadmus Fldr. (149 c) has, like the following, a much rounder shape of the wings, above in the cddniut!. 

 basal half of a radiant greenish-blue, outside blackish-bro\\n, before the anal angle with the beginnings of a 

 blue marginal line. The .-; is a little duller, more silvery. The under surface is red-yellow, again with the same 

 light-blue linear markings which, however, are here much more dentate, particularly on the hindwings. Common 

 in Panama, Colombia, Bolivia, \'enczuela, Guiana. 



Th. timaeus Fldr. (149 c) is above bluer, the apex of the forewing somewhat more pointed, the tails Ihnacu.'i. 

 shorter. Beneath, the forewings have only one bluish-white transverse line, and at the apex there are 1 or 2 

 white dots, the lines on the hindwing are not so dentate, running more uniformly, ("olombia, Bolivia. 



Th. petelina IIcic. (149 d) not lying before me is placed here. Above very much like the two preceding ihIcI'uki. 

 ones. Beneath red-brown, on both wings a white discal streak, behind it 3 white transverse lines; on the hind- 

 wing, besides, a moon-shaped spot near the base, in the centre a light-blue macular band and behind it a broad 

 red-brown, white-bordered band; the spot of the tail and the anal spot brown, proximally bordered by light- 

 yellow. From Costa Rica and Panama. 



22. Havila- Group. 



Th. adamsi Die. (148 h) is difficult to place; as it is compared with hnviln by the author, it may ailnmsi. 

 be placed here, although it has no scent-spot and has 2 tails, for which reason it would have perhaps been better 

 placed to the aegides- or danaus-gxo\\\i (p. 753). Above lustrous greenish-blue, towards the margin more i)ur])le; 

 distal margin narrow black. Beiieath chocolate-brown with bluish-white lines. Peru. 



Th. havila Heu\ (14SI)) is not well recognizable from HEWITso^'s figure being copied here. The liarihi. 

 1^ is above deep ultramarine-blue, towards the margin of a puiple lustie. Scent-spot oblong, double, the part 

 in the cell browner than the blackisii jiait behind it ; anterior angle of the hindwing particularly broad black. 

 The under surface is greyish brown witli :i, towards the anal angle somewhat convergent lines of a blue scaled 

 striation, those towards the margin broader and more faded; between the median veins of the hindwing a 

 small red-yellow, black-marginetl eye-sjiot. .\bdomen beneath orange-ycllcjw. Colombia. 



Th. margaritacea 67;. mw. (153 b). Uj)]:)er surface light greenish-blue, with a mother-of-pearl gloss, nian/nrild- 

 entirely without the black iv.argin. only the fiinges blackish grey. The brown scent-spot small, procumbent- "'' 



oval, pointed at both ends, behind the vvU. Hindwings remarkably long-stretched; in the specimen before 

 me there is only one tail, but there seems to have been a short small tail also at the upper median vein. Under 

 surface of the forewings opalescent greenish-blue with a narrow, blackish-grey costal margin and apex, 

 the place of the scent-spot prominent as a small hunch; hindwings bhu-kish-grey, sparsely strewn with green, 

 in the cell and towards the proximal )nargin covered with long hair. A little before the middle of the costal 

 mai'gin, in the subcostal space, a bluish-green streak-spot; in front of the border 3 lather closely adjacent, 

 bluish-green silvery line^, indistinct, consisting only of scattei'ed, single scales. Anal lobe as in ddiiau.s ( 149 b), 

 to which it may also be allied, somewhat split I ^ from Muzo, Colombia. (Coll. Fas.sl.) 



Th. celelata Hew. (149 c) is likewise a species difficult to place. Above something like mf/?KM.« (149c), nlcln/ti. 

 beneath brown, marked like h/ivilii { Its b), but on each of the wings one whitish line nearer to the base: the 

 costal margin of the forew^ing is stiewn with white, all the while lines broad, somewhat faded and strewn with 

 brown. Described from Brazil.
