THECLA. By Dr. M. Draudt. 749 



Th. augustula Ky. (= augustinus Btlr. & Drc.) (147 e) is very similar beneath, but the proximal margin angustvla. 

 of the forewings is brown, in theocritus silvery blue. The ground-colour above is a deep blue, with metallic 

 green spots near the anal angle. From Mexico to Panama. 



Th. monica He^c. (147 g) is above somewhat more greenish than the preceding -ftith a less extensively monica. 

 black apex of the forewii.g; beneath duller greyish-brown with a light, partly white-chequered apical part and 

 smaller indistinct greenish spots which are arranged almost like in lisus (148 a). The (;J-hindwings exhibit beneath 

 yellowish-white scent-scales hidden in a hairy fold below the median. Veriezuela, Colombia. 



Th. gispa Hew. (147 e) probably also belongs into this group. It is larger, above metallic-blue with ^j-s-pa. 

 only narrow black margins, in the ^ with a discal spot at the cell-end. Beneath dark-browTi, the inner-marginal 

 half of the forewing of a brilliant silvery-blue, the hindwing in the distal half green, clouded in brown, traversed 

 by a brown band, veins broadly brown. Apparently very rare. Amazon. 



Th. hamila Jones (147 f) is much smaller than the preceding, otherwise very closely allied to it hamila. 

 with a large scent-spot. Beneath very easily recognizable by the sooty-black colour covering the whole wings, 

 which is, however, much too little expressed in the figure. Castro (Parana), Rio Grande do Sul, Sa. Catharina. 



Th. crines Drc. (147 e, f) is very similar, the wings a little broader, above with a more intense metallic crines. 

 lustre, beneath the blackish-brown ground-colour in the basal third of both wings densely strewn with emerald- 

 green scales and in front of the distal margin of the hindwing there stand 3 or 4 more or less complete ro^vs of 

 magnificently metallic-green lunular spots. The $ is of a much duller blue, above tvith very broad brown margins. 

 So far it seems only to have been found in Colombia. 



11. Hemon- Group. 



Th. lisus SfoU (= hisbon Godm. & Salv.) (148 a, 147 f) is above metallic ultramarine-blue without ?i.s-i«. 

 a scent-spot with narrow black margins ai.d a darkened apex, in the $ more greenish-blue -with very broad 

 brown margins. The under surface is very variable, brown to black with 3 whitish to green, undulated lines 

 in front of the distal margin of the hindwing and an angularly broken row of small, bluish-white or green spots 

 in the disc, the uppermost of which is black-pupilled outside at the costal margin. The differences mentioned 

 by GoDMAN as to his hisbon are merely individual. Wide-spread and everjr^vhere common from Guatemala 

 to Colombia and Bolivia. 



Th. viresco Drc. (153 b) differs by a more compact structure, a greener upper surface with somewhat viresco. 

 broader margins and the opalescent green disc of the forewing beneath. From Brazil and Colombia (Rio Negro). 

 — photeinos Drc. (147 f), differing only above and beneath by a lustrous-blue colour is probably scarcely a photeinos. 

 different species. From Brit. Guiana. 



Th. orsina Hew. (148 a) I do not know; it is presumably scarcely specifically separable from lisus; orsina. 

 it is said to differ by longer hindwings and a lighter greyish-brown under surface. Bolivia. 



Th. phegeus Heiv. (147 f, g). The figure is entirely unable to give an idea of the splendour of the phegeu^. 

 colouring; the forewings are above brilliantly sky-blue with a milky-white prominent sexual-spot. Beneath 

 marked as lisus, but of a dark-green ground-colour, at the proximal margin of the forewing blae. Bahia, 

 Amazon. 



Th. laudonia flew. (148 a) forms the transition to the following species which it almost entirely resembles laudonia. 

 beneath, except the dark-green ground-colour as in phegeus. Above the wings are of a deep peacock-blue with 

 a small, equally coloured scent-spot being visible only at an exposure to an oblique light. Amazon, Colombia. 



Th. hemon Cr. (= acmon Cr.) (147 g) is larger than the preceding, above equally coloured, but with hemon. 

 a very much larger scent-spot; beneath blackish-brown with a blue proximal half of the forewing. The 5 is 

 above dull brown, also beneath, here like the (J with metallic-green transverse lines and a white, black-pupilled 

 eye-spot in the middle of the costal margin. The species flies the most frequently in Brazil m the Amazon 

 district, in Guiana and Colombia, more rarely in Central America from Guatemala to Panama. 



Th. arogeus Cr. is a species that has apparently not been identified hitherto, but presumably arogeus. 

 belonging here. Above like the preceding, beneath green, the darkest at the base of the hindwings, towards 

 the margin light-blue with black transverse lines, the innermost of which in the centre forms 2 verj' large bows 

 like the number 3. Described from Surinam. 



12. Deniva-Group. 



Th. deniva Hew. (147 c, d) approximates the preceding group by the split anal part of the hindwing; rf€?iiio. 

 the marking beneath likewise shows a resemblance in the scheme; the apex of the forewmg is clipped. Above 

 the (^ is metallic-blue, the $ dull violettish-blue, beneath brown. Brazil.
