THECLA. By Dr. M. Dbaudt. 747 



Th. gabrlela Cr. (= gabrielis Godt.) (146 f) is vrery similar; on the under surface of the forewing the gabriela. 

 proximal transverse stripe extends down as far as below the lower median vein, on the hindwing the broad 

 black transverse band forms an oval and, beneath the subcostal vein, it is broad and not strangulated, forming 

 a W at the proximal angle; the red band is very broad on both surfaces, but not sharply defined by white. 

 Colombia, Amazon. 



Th. sponsa Mschlr. differs from gabriela above by a larger, carmine anal-angle-spot of the hindwing, »ponsa. 

 beneath by the red spot reaching from the proximal margin only to the upper median vein, in which there are 

 2 black spots. Surinam. 



Th. batesii Hew. (146 f) likewise greatly resembles gabriela, though it is easily distinguishable by the bafesii. 

 under surface of the hindwings, exhibiting only a rather uniformly broad, red-brown band divided by a white 

 line, and forms only a V, not a W, at the proximal angle. Brazil. 



Th. sumptuosa Drc. (= gabriela Godt.) (146 f) is above separable by the large, silky-grey scent-spot smnpluosa. 

 of the forewing, being situated below and behind the cell. On the under surface of the hindwing there is only 

 an oval, red-brown band being distally bordered by a white line and behind it by a black line. Brazil (Espiritu 

 Santo, Sao Paulo). 



Th. candidus Drc. (147 a) is very similar and perhaps only a form of the preceding species with a candidus. 

 scent-spot being taperingly prolonged towards the base below the cell. Beneath of a magnificent bluish-green 

 with very distinct markings, the black being increased on the forewings, and like in sponsa, there is only some 

 red with black spots therein towards the anal angle on the hindwing. From Colombia (Muzo). 



Th. ornatrix Dro. (146 f) has beside the scent-spot of the preceding yet a second one above the omairix. 

 median in the cell; beneath likewise very similar to sponsa. Described from Brit. Guiana. 



Th. regalis Cr. (= endymion F.) (146 e) differs greatly from the preceding and approximates coronata regalis. 

 the most, from which it differs beneath by the transverse lines being not distally but proximally bordered by 

 whitish-grey; the one on the hindwing does not quite touch the red transverse band, but it is separated from 

 it by the green ground-colour. Above the blue grows somewhat more greenish and there are red anal spots 

 in both sexes. The black margin of the wings is comparatively broad and proximally not faded, but sharply 

 defined. Occurs most widely distributed from Mexico to the Amazon. 



3. Tagyra-Group. 



Th. tagyra Heiu. (147 b) is a very strange animal, above blue with a silky-grey sexual-spot of iagyra. 

 varying size, beneath likewise blue with black, distinct transverse bands. — floralia Drc. (147 b) has been raised floraUa. 

 to a species, but the only difference is the prolonged (J-spot ; the latter, however, varies (as in some other 

 species) sometimes from one specimen to another, so that it cannot be a specific mark of distinction. Described 

 from the Amazon district, also before me in a couple being beneath of a somewhat lighter turquoise-blue with 

 narrower black bands, from the Rio Songo (Fassl). 



4. Eplscopalis- Group. 



Th. episcopalis Fassl (153 a). Very different from all the other species known. Above of a radiant episcopalis. 

 golden-green with narrow black margins and a broader apex, beneath on the forewings metallic-blue, towards 

 the margin warming into a golden-green; hindwings green with 3 black transverse bands being convergent 

 towards the proximal angle and in an oblique light gleaming in a magnificent peacock-blue. Discovered by 

 A. H. Fassl in the West Colombian Andes at an altitude of 2000 m (Rio Aguaca Valley), where the species 

 was flying round the tops of trees in the morning-sun. 



5. Nobilis- Group. 



Th. nobilis H.-Schdff. (= bimaculata Mschlr.) (147 a $, 153 a (^). This group, strictly speaking, nobilis. 

 likewise contains only one representative, if one does not want to place the species in the gabriela-gvowp. The 

 (J is greatly distinguished by the fact that, beside the roundish grey cell-stigma, there is another oblong black 

 spot at the end of the submedian, which, however, does not contain any scent-scales. Beneath similar to the 

 gabriela-group with a very broad red band of the hindwing. From Guatemala to Colombia and Guiana. 



Th. telemus Cr. (= antinous Fldr.) (147 a, b) we include here for the sake of exterior resemblances, ielemns. 

 (J above lustrous sky-blue with an extremely fine black border; the tails are also blue. Stigma grej'ish-brown, 

 behind the cell-end; $ of a more subdued blue, with broad, blackish-brown margins. Under surface green with 

 an extremely variable marking and colouring, so that there is nodistinct delimitation to antinous Fldr. (147b). anfitwus.
