THECLA. By Dr. M. Deaudt. 749 



Th. augustula Ky. ( = augustiims Btlr. A- Drc.) (147 e) is very similar beneath, but the proximal margiii aiigi'slNhi. 

 of the forewiug.s is brown, in theocriiU'i silvery blue. The ground-colour above is a deep blue, with metallic 

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



Th. monica Hew. (147g) is above somewhat more greenish than the preceding with a less extensively nuniira. 

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

 smaller indistinct greenish spots which are arranged almost like in Usus { 148 a). The ,j'-hindwings exhibit beneath 

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



Th. gispa Heu\ (147 e) probably also belongs into this grou]). It is larger, above metallic-blue with ;/;.s//«. 

 only narrow black margins, in the J with a discal spot at the cell-end. Beneath dark-brown, 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 hainilu. 

 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 ba^al 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 rows of 

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

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



11. Hemon-Group. 



Th. lisus Stoll {= hisbon Go(hn. <£■ Salv.) (148 a, 147 f) is above metallic ultramarine-blue without /;.s»s. 

 a scent-spot with narrow black margins ai cl a darkened apex, in the $ moie 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-sjiread and everywhere common from Guatemala 

 to Colombia and Bolivia. 



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

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

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

 different sjiccies. From Brit. Guiana. 



Th. orsina Hew. (148 a) I do not know; it is j^resumably scarcely specifically separable from lisus; or.-ihm. 

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



Th. phegeus Hew. (147f, g). The figure is entirely unable to give an idea of the splendour of the jtJieyeu.s. 

 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, 

 Anuizon. 



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

 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 exjaosure to an oblique light. Amazon, Colombia. 



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

 a very much larger scent-spot; beneath blacki.sh-brown with a blue proximal half of the forewing. The V 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 frecjuently in Brazil in the Amazon 

 district, in Ciuiana 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 aroijcus. 

 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 very large bows 

 like the number 3. Described from Surinam. 



12. Deniva-Group. 



Th. deniva Hew. (147 c, d) apjM-oximates the preceding group by the split aiuxl part of the hindwing; dcnira. 

 the marking beneath likewise shows a resemblance in the scheme: the apex of the forewing is clipped. Above 

 the c? is metallic-blue, the V dull violettish-blue, beneath brown. Brazil.
