THECLA. By Dr. M. Deaudt. 779 



Th. nivepundata Drc. (155 f). We add here 2 very different species being otherwise not related to nivepi'-ncta- 

 any other group. The species before us has above the greasy-lustrous indigo-blue of spurina (152 h, i), but ^• 



a much broader dark apex and at the cell-end a pear-shaped, brownish scent-spot. Beneath not to be mistaken 

 for any other species by the chocolate-coloured, white-dotted under surface. The $ is above duller coloured, 

 otherwise the same. From British Guiana and Surinam. 



Th. porphyreticus Drc. (155 f). Above about as tephraeus, but with a broader black margin and a porphyreli- 

 smaller dark-brown scent-spot. Beneath brown with a violet reflection, very characteristic by the two large, '^"*" 



white, costal-marginal spots of the hindwing. Peru (Rio Napo). 



66. Syncellus-Group. 



Th. syncellus Cr. (151 i, k). ^ above magnificently lustrous blue with a moderately broad black syncellug. 

 margin and a black scent-spot behind the cell, bordered in the cell by a smaller, red-brown spot being circum- 

 scribed like an eye by slate-blue. Beneath greyish-black with a darker transverse line and silvery green dusting 

 at the anal angle in the shape of 2 short transverse lines, the proximal one forming a W; abdomen beneath 

 yellowish-white. The $ is above darker steel-blue, beneath more yellowish-brown. Everjrwhere extremely 

 common from Mexico to the Amazon; northern specimens generally have a narrower black margin. — From 

 West Mexico (Guerrero) I received a number of specimens of a smaller, much lighter form with an almost extinct 

 scent-spot and beneath light yellowish-grey ground-colour, which I denominate deserta form. nov. (151 k); — deseria. 

 eribaea Heiv. (151 k) is a form with the postdiscal on the under surface being distally broadly dusted by light- erihaea. 

 blue, from the Amazon. — hitias Cr. is most probably a synonym of syncellus. 



67. Hebraeus-Group. 



Th. hebraeus Heio. (151 k) entirely resembles above our figure of deserta (151 k), but it is of a more hebraeus. 

 violet coloiu-, the scent-spot is the same, smaller than in syncellus, the extensive black part behind the cell 

 is absent. Beneath brownish with undulate, black streak-markings which are well to be seen from the figure. 

 Bahia. 



Th. cimelium Gosse (151 k) is extremely similar and above not to be distinguished, the under surface, dmelium. 

 however, is much more clouded in dark and more indistinctly, more blurredly marked. Brazil to Paraguay. 



68. Pelion-Group. 



Th. pelion Cr. (= simplex Walch., ^ thallus Cr., aeolus F.) (148 e). Above blue with a narrowly pelion. 

 black margin and a large, black scent-spot. Beneath blackish-grey with a slight purple tinge and a broad, white 

 band of the hindwing parted by the veins; between the median veins an antemarginal, carmine spot, at the 

 anal angle some silvery-blue scaling. Brazil, Trinidad, Ecuador. 



Th. paphlagon Fldr. (148 f). (J above radiantly greenish-blue with a large, black scent-spot at the papMagon. 

 cell-end and some black dusting behind it. Distal margin narrowly black. On the upper surface of the hindwing 

 there is a pencil of black hair on the submedian. The $ is more green with a much broader, blackish-bromi 

 margin. Beneath brownish-grey with a whitish inner-marginal area and black veins, a small, white, costal- 

 marginal spot of the forewing and a yellow apical spot of the hindwing, in front of the anal margin of which 

 there are 2 red spots. Colombia, Venezuela, Peru. 



Th. ochus Godm. <& Salv. (148 f) resembles the preceding above, darker blue and with a much larger ochus. 

 black discal spot below the scent-spot and a black hair-pencil at the submedian. Beneath likewise similar, 

 the light costal marginal spot of the forewing is larger and triangular, the apical spot of the hindwing not yellow 

 but whitish, extending subcostally as far as the base. Before the margin only one red spot, a smaller one in 

 the anal lobe. Mexico, Guatemala, Panama, Costa Rica. 



Th. boreas Fldr. (148 f) likewise belongs here; it is smaller, above similar to paphlagon, beneath borcas. 

 much more variegated by more abundant yellow spotting, a red costal margin of the hindwing, and more 

 extensively red spots between the median veins and above them. Colombia, Amazon. 



69. Coelebs- Group. 



Th. coelebs H.-Schdff. (= fidena Hew.) (155 f, g) is above lustrous steel-blue, more greenish than coclcbs. 

 spurina (152 h, i), distally very broad blackish-brown with long hair above in the submedian space of the 

 hindwing and a hair-pencil at the base of the subcostal, without a scent-spot. The 2 is above duller greyish- 

 blue. Beneath brown, the postdiscal line darker, on the hindwings distally white, beginning in the middle 

 of the costal margin; anal lobe black, above bordered by white, between it and the large red spot of the tail 

 blue dusting. Cuba, Hayti.
