768 THECLA. By Dr. M. Drafdt. 



iancia. Th. fancia Jones (152 b) closely allied to the preceding is above brilliantly metallic-blue with a greenish 



lustre in the basal half. The under surface is more j^ellowish-grey, the submarginal macular band of the forewing 

 is more distinct, distally broad white, reaching down as far as the lower median vein, on the hindwing the 

 proximal macular band is placed not so near to the margin, the spot of the tail is smaller, orange. Castro 

 (Parana). 

 echelia. Th. echelta Hew. (152 f) is another stage of development of polibetes (152 c) in which there appears 



a broad black discal band on the fore- and hindwings; in the upper cell-corner is the small round red-brown 

 scent-spot. The under surface is lighter reddish-brownish, the marking almost as in vibidia (152 c). Amazon. 

 phoenissa. Th. phoenissa Heiv. (152 e) we include here; above like thyrea (152 f), somewhat duller indigo-blue 



with a greenish shine, the veins of the forewings broader black, the scent-spot somewhat larger. The $ is duller 

 greyish-blue with a dull metallic lustre. The under surface makes the species very easily recognizable by the 

 abundant white marking. From Nicaragua, Panama, Colombia to the Amazon. 

 sdica. Th. selica Hew. (152 c) somewhat resembles m-album (152 d) beneath, but between the postdiscal 



lines and submarginal macular bands it has on each of the wings a straight broad band of bluish-white dusting 

 inserted ; on the hindwing the costal-marginal spot has turned a streak, and often, particularly in the $, there 

 are in the basal area some more bluish -white streak-markings. Above lighter greenish-blue, with a small round 

 bro\\ai scent-spot; the $ is very similar, duller, with broader margins. Colombia, Bolivia, Brazil. 



44. Rustan- Group. 



rustan. TH. rustan Stoll (= macaria Sws.) (152 a) has very close relations to the preceding group. The 



^ is above dark-brown, only in the basal inner-marginal half of the forewing it has a dull blue tinge, with red- 

 brown fringes, on the hindwing analwards a black marginal line and white hair at the anal lobe. The scent- 

 spot is extremely complicated : at the cell-end a dark-brown round spot, in which there is distally a light fawii- 

 colom'ed sector; behind the cell a four-cornered black spot, the proximal one is yet surrounded by slate-grey. 

 The 9 is duller, more extensively greyish-blue. Beneath with very characteristic markings. From British 

 Honduras, Panama to Brazil. 

 polama. Th. polama Schs. presumably belongs here. Above dark violettish-blue with a narrow black distal 



margin with a long scent-spot being parted by a violet line, the proximal half lighter, the distal half darker 

 brown; fringes red-brown. Beneath of a silky-lustrous brown, very similarly marked to rustan (152 a), but 

 the spots a little finer, not so thick and more bordered by white ; abdomen with a golden yellow, black-margined 

 ventral line. The (J exhibits above and beneath darker and duller colours. Petropolis in South Brazil. Expanse 

 of wings: J 35, $ 36 mm. 

 ortygnus. Th. ortygnus Cr. (152 a) is above lustrous lilac-blue with moderately broad black margins and only 



a small brown scent-spot at the upper cell-end; proximal margin and anal lobe almost white, the latter with 

 a black spot. The under surface is very pale lilac-grey with thick black spots arranged in the same way as in 

 rustan, but the forewings are without the antemarginal band; the anal angle of the hindwing is extensively 

 greenish and strewn with bluish-white. The 2 is above coloured the same, but it has broader brown margins. 

 EveryTvhere common from Mexico to Brazil, also in Trinidad. — In the stony deserts of West Mexico (Guerrero) 

 lauta. there flies a smaller, remarkable form which I denominate: lauta form. nov. (152 a); it is above lighter lilac, 

 M'ith a milky tinge, beneath ^^•ith much smaller and dull bro^^'n markings that are tending to form more coherent 

 lines. 



45. Jebus-Group. 



jebus. Th. jebus Godt. (152 b) is quite an isolated species, above dull steel-blue, with narrow black margins, 



and particularly in northern specimens with a red-bro-mr anal spot of the hindwing and a small brown scent- 

 spot in and above the upper cell-end. The $ is milky greyish-blue, with broad greyish-brown margins. The 

 peculiarly brown marbled under surface of the hindwings makes it impossible to mix it up with other species. 

 From Mexico to South Brazil and Peru, everywhere common. 



46. Brescia-Group. 



brescia. Th. brescia Hew. (= thoana Hew.) (152 f) is so closely allied to punctum (152 d) and its nearest 



allies that it must be made optional to the individual observer whether he prefers to range punctum into this 

 family or not. Above lustrous blue with moderately broad black margins and a small, round, light-brown scent- 

 spot at the upper cell-end, anal lobe orange. The $ is above greyish-brown, distally broad darker brown. The 

 under surface is greyish-brown with a lilac reflection, marked almost the same as punctum, on the forewings 

 with a distinct postdiscal band. Mexico to Nicaragua. 

 orses. Th. orses Godm. d- SaJv. (152 g). Like the preceding, with a broader black apex of the forewing 



and beneath at the anal angle with ochreous-yellow spots, not red ones. From Guatemala.
