786 THECLA. By Dr. M. Draudt. 



Umnria. Th. lemuria He^o. (156 d) is considerably smaller, above deep ultramarine-blue, with an oval, dark- 



brown scent-spot behind the cell and a moderately broad black apex, a narrow distal margin. Beneath light 

 brownish-grey, marked like em-pusa. Colombia, Brazil. 



coll iifit ra . Th. collustra Drc. (156 d) does not differ beneath, but above it is greyish-black, of a purple lustre, 



without a scent-spot, the liindwing in tlie proximal half more indigo-blue with a small red anal spot. Trinidad. 



argrmna. Th. argerona Heu\ (156 e) is fin the forewings above only at the base and in the disc of the hind wing 



somewhat darker, more indigo-blue. Beneath light reddish-grey, marked like the preceding, on the forewing, 

 only a short postdiscal extending neither to the costal margin nor to the jiroximal margin; on the hindwing 

 the grey .spot between the spot of the tail and the anal spot is above also bordered by red. Brazil. 



melm'j. Th. melma Schs. (156 d) seems to belong into the same group. Above of a purer blue with a less extensive 



apical black than in empusa, beneath more olive-brownish, the lines more distinct and broader, the space bet- 

 ween the anal spot and tlie spot of the tail du.sted in a bluish white. C'osta Rica, Panama. 



nphki. Th. ophia Hew. (156 e) is above extensively blackish-brown, only towards the base and proximal 



margin greenish-blue with a large, dark, hai'dly visible discal spot without any scent-scales, the forewings 

 entirely blue except the broad costal margin and narrow distal margin. Beneath brownish, marked like lemuria 

 (156 c), but somewhat more jjrominent, tlie submarginal macular bands more distinct, also on the forewing. 

 Amazon. 



Inronia. Th. laconia Hew. (156 e) looks above just the same, but it has a large, oval scent-spot. Beneath 



lighter, the lines finer, lighter, more strongly broken, more remote from the border. Amazon. 



cupii. Th. CUpa Drc. (156e) differs from laconia by the blue entering into the cell of the forewing and a 



broader black costal margin of the hindwing; at the cell-end of the forewing lies only a small, round, indistinct 

 scent-spot instead of the large oval one in laconia. The under surface is lighter, the discal bands proximally 

 bordered by brown, on the forewing in the lower half removed more towards the margin. Rio Grande. 



(jnosia. Th. gnosia Hew. (156 e) probably belongs to the same group, it has a rounder shape of the wings, 



is smaller, above of a purer, though more subdued blue, the 9 brownish, with violettish-blue hindwings. The 

 under surface entirely resembles that of the preceding. Colombia. Peru, Bolivia. 



80. Echion- Group. 



cr-hion. Th. echioH L. (= crolus Cr.) (156 e, f) is a very variable species: above dull-lustrous indigo-blue with 



a very broad blackish-brown apex of the forewing and costal margin of the hindwing; the larger distal half 

 of the cell is filled up with scarcely contrasting, dark-brown scent-scales of a slight steel-blue lustre. The 5 

 is much duller with a white marginal line on the hindwings in the anal direction. Beneath lighter or darker 

 brownish-grey, particularly in the $ often whitish-grey, in the (J the disc of the forewing is more brown, in 

 some places clouded in a somewhat darker colour, the forewings with 2 lines, the hindwings with roundish, 

 copper-coloured to light-orange spots, bordered by black, before the distal margin a dentate line, and the usual 

 orange-red, black-pupilled, small spots. Very common from Mexico to South Brazil. — A smaller form flying 

 i'rhiohi.<:. in Mexico, echiolus fortn. nov. (156 f) shows the spots on the hindwings beneath more subdued, more pale-orange 

 with a disappearing dark bordering. 



(rolhiii.'<. Th. crolinus Btlr. (156 f) is similar, but above much more extensively and brilliantly blue, so that 



the whole proximal half of the cell remains blue, behind it a four-cornered, black discal spot. Beneath not 

 essentially different, but the spots on the hindwings are not so round, but more oblong, so that more of a trans- 

 verse band is produced. Mexico to Panama. 



riiniihd. Th. vomiba *SV/(.s. seems to be closely allied to crolinu.s, on the forewing tlie blue is confined to an inner- 



marginal stripe, beneath it differs by a more complete additional basal of the hindwing, which is somewhat 

 interrupted only above and below the cell. Expanse of wings: 22 mm. Petropolis in South Brazil. 

 veiiiislii.'i. Th. venustus Drc. (156f) is above like crolinus, the fringes of the forewing copper-brown. Beneath 



darker brown, on the forewings the postdiscal band is much straighter; we do not find any real difference from 

 crolinus. Described from Brazil. 

 JaJ><:'<. Th. labes Drc. (156f) is smaller, above dull brown with a large black scent-spot, the hindwings only 



in the proximal half are slightly tinged in a greyish blue. Beneath there is no difference from echion; it is 

 perhaps only a small form of it, from Trinidad. 



philinmi. Th. philinna HeuK (= unilinea Kaye) (156 g). Above similar to echion, but with quite a different 



scent-spot in two parts being placed almost vertically above each other: the upper part grey, the lower one 

 brown. The under surface is likewise similar, but without the basal spots of the hindwings and extremely variable, 

 white to bro-wnish-grey, the spots themselves sometimes golden-yellow, sometimes copper-orange, or dul
