776 THECLA. By Dr. M. Draudt. 



lUcmius. Th. literatus Drc. (155a) ha^ above quite brown forewings with a small, h'ght, opal scent-spot; 



hindwings brown, in the larger jiroximal half metallic blue, with a red anal spot. The under surface is lighter, 

 the markings as in besidia, but narrower and distally bordered by a pure white. The 9 is on the hindwings 

 dull greyish-blue with indistinct, small, brown marginal spots. Paraguay. 



nufjar. Th. nugar Schs. (155 b) is very closely allied to the preceding. Forewings brown with a small light 



scent-spot, hindwing in the larger proximal half metallic light lilac-blue. Beneath bi'ownisji-grey, the proximal 

 line orange-brownish, distally white, between the radial veins dislodged outwards, the costal .spot, however, 

 onlv slightly so. Described from Mexico (Jalapa), but it is before me also from Colombia (Rio Aguaca Valley) 

 and from the Songo (Bolivia) and, therefore, apparently widely distributed. 



a-orenui. Th. xorema Schs. is likewise similar, above like obelus (152 k). beneath lighter: the transverse bands 



are dai'k-brown, not red, outside broadly whitish; the $ is above dark-brown, towards the base suffused with 

 blue. Expanse of wings: 20 mm. Brazil. 



cautcr. Th. catiter Drc. (152 i). Above likewise very much like obelus (152 k), the blue more indigo-coloured, 



the distal margin of the hindwing broader black and with a very large, red anal spot. Beneath more rusty- 

 brown, the markings very broadly tinged in red, the postdiscal band of the forewing, beginning from the lower 

 radial vein, dislodged inwards, that of the hindwing on both sides bordered by black and then by white, the 

 whole anal area extensively red. The $ is above brown with a large, orange anal spot. British Guiana. Brazil. 



Janckcna. Th. latickena Schs. is allied to bngradn (152 k). Above unicolorously blacki.sh-grey with a red anal 



• spot of the hindwings. Beneath light-brown with red, distally black-, then white-bordered lines, on the hindwing 

 at the costal margin, then between the radial veins distally expanded, otherwise like the allies. Expanse of 

 wings: 28 mm. Peru. 



61. Tiasa-Grouj). 



tiasa. Th. tiasa Hew. (155 b). ^J above deep purple-blue with comparatively narrow black margins and a 



small double scent-spot, inside black, outside greyish-brown; at the anal angle of the hindwing a red spot. 

 Beneath brown with white lines, on the hindwings contiguous: the extensive red anal spot connected with 

 the spot between the median veins by a red band. Amazon. 



ortaliis. Th. ortalus Godm. & Snlv. (155 b) is very closely allied to the preceding; the ^J is above less purple- 



blue; on the under surface of the hindwing the white lines diverge more from each other towards the costal 

 margin. The $ is above jjlainly brownish-grey with a greenish reflection at the base of the wings. From Mexico. 



praxis. Th. praxis Godm. <£■ Salv. (155 b) differs from ortalus by the much broader blackish-brown apex 



of the forewing. The anal lobe is beneath black, upwards but quite slightly red, towards the proximal margin 

 strewn with white; between it and the small red spot of the tail lies a blackish spot in the brown ground. The 

 $ is above dull brownish-grey, towards the base with a slight, bluish-grey tinge. Panama to Brazil (Sta. Ca- 

 tharina). 



62. Erix- Group. 



erix. Th. erix Cr. (= tyrrhenus Hbn., erissus Hbst.) (155b). Above magnificently ultramarine-blue with 



a moderately broad, black margin ; the discoidal cell is very short, therefore the position of the small black 

 scent-spot in the upper corner near tlie base, above at its outside it is touched by a tiny brown scent-spot at the 

 base of the subcostal veins; at the anal angle a minute red-brown s])ot. Beneath coffee-brown, on the forewing 

 with 2 antemarginal lines, the inner one of which is distally bordered by white. Hindwings darker with a bluish- 

 white, proximally dark-tinged, postdiscal W-line and an antemarginal row of dark spots, bordered on both 

 sides by a lighter colour and being interrupted between the median veins by a red, black-pupilled spot. In 

 the anal lobe a red spot bordered above by black and white. Amazon. 



iimoclca. Th. tiiiioclea Hew. (155 c) is considerably larger, darker indigo-blue, with a nuich larger, oval, blackish- 



brown scent-spot surrounded by slate-green scent-scales, with a broader black apex. Beneath similar to trix, 

 the fine lines formed of silvery-blue scales sprinkled on it ; at the base of the ccstal margin is a silvery-blue dot. 

 From Ecuador. 



celm. Th. cetra sp. nov. (155 c) resembles the preceding above, but it has longer hindwings, a duller steel- 



blue colour and a larger, double scent-spot, the proximal half being red-brown, the distal half, being separated 

 by the blue transverse vein, greyish-brown. Beneath very similar; on the forewings the curved proximal line 

 is likewise bluish-white, on the hindwings the blue basal dot is absent, tlie postdiscal line is clearer, not composed 

 of dispersed scales. According to a pure J from Muzo (Colombia) from the Coll. Fassl.
