THECLA. By Dr. M. Draudt. 797 



Th. plusios Godm. cfc Salv. is a somewhat doubtful species which neither fits entirely to dewxrius, nor plusios. 

 to sethon (158 c); it differs from the former by its more red-brown wings and not darkened discal area. Mexico 

 to Panama. 



Th. perisus Drc. (158 c) is above monotonously dull brown with a small orange anal spot of the hind-ning, perisui. 

 beneath much lighter brown than denarius, equally marked, only the postdiscal band of the fore-nang is parallel 

 to the distal margin, in denarius somewhat obliquely placed to it. Venezuela. 



Th. joya Dogn. (= callao Drc.) (158 c) is above dark copper-brown, with a brown costal margin, jorja. 

 apex and distal margin, on the hindwings towards the proximal margin densely yello-wish-haired. Beneath 

 dark brown-grey, in the basal part, especially of the hindwing, darker than outside; the postdiscal lines rusty 

 brown, distally tinged light-grey, the submarginal line composed of light-grey crescents, otherwise like cyphara. 

 Peru. 



Th. rugatus Drc. (158 d) greatly approximates denarius and sethon. Above dull olive-brown, the ruyaiaa. 

 hindwing towards the proximal margin with copper-coloured hair and a small orange anal spot. Beneath uni- 

 formly light olive-brown, the postdiscal line almost straight, broad dark-orange, distally bordered by black, 

 then sharply by white; small, submarginal, dark nebulous spots, the spot of the tail large and of a brilliant 

 orange. Abdomen beneath white. The $ is above and beneath lighter. Peru. 



Th. nubilum Drc. is closely allied to sethon (158 c). Above blackish-brown with a small orange anal nuVilum. 

 spot. Beneath greyer, the postdiscal lines narrower, straighter and nearer to the distal margin. Castro (Parana). 



Th. fernanda Jones is above just the same, beneath yellowish grey-brown, the postdiscal line on the iemanda. 

 forewing straighter, on the hindwing less sharply angled with a distally displaced costal-marginal spot; there 

 are no discal streaks. Expanse of wings: 29 mm. Parana. 



Th. tirrhaea Mschlr. is unknown to me; size of acaciae (Vol. I, t. 73 b), hindwings rather long-stretched; Hrrhaea. 

 above plainly dark-brown, beneath lighter brown; the postdiscal line on the forewing straight, dark-brown, 

 on the hindwing more dissolved into spots, towards the proximal margin angularly broken and distally bordered 

 by white; double, darker brown, small submarginal spots; the spot of the tail large, oval, black, proximally 

 edged by red-yellow, distally by white, between it and the black anal spot white dusting. Length of forewings: 

 13,9 mm. Surinam. 



96. Clarina-Group. 



Th. clarina Hew. (158 d) is above blackish-brown, at the costal margin of the hindwing brOliant Morpho- clarina. 

 blue. Beneath reddish-brown, the postdiscal line is almost straightly carried through as far as the W and on 

 the hindwing on both sides bordered by orange; the anal lobe with a small black spot, the spot of the tail 

 orange, pupilled in black. Mexico to Panama. 



Th. tamos Godm. db Salv. (158 d) is duller coloin'ed, the blue which is much darker, is situate at the iamos. 

 proximal margin, not at the costal margin. The under surface is very characteristic by the very much broadened 

 postdiscal band of the hindwing, the submarginal band consists of white, distally black-bordered crescents 

 and touches the discal side of the W on the lower median vein, it is, between the radial veins, placed nearer 

 to the distal margin. Costa Rica, Panama. 



Th. matho Godm. <& Salv. (158 d) is not different above, beneath the white band of the hmdwmg is maiho. 

 only half as broad, the submarginal line uniformly undulate, not moonspotted. Brit. C4uiana to Bolivia (Rio 

 Songo). 



Th. Clarissa sp. nov. (158 d) we include here as the nearest ally. Above there are resemblances to darissa. 

 tarania (p. 810, t. 160 c, d), dull brown with a broad orange band in the anal part of the hindwing as far as 

 beyond the lower radial vein. Beneath light-brown with white, proximally orange-bordered postdiscal lines, 

 on the hindwings straight as far as the submedian, then in a plain, right-angled curve to the proximal margin; 

 a broad, orange antemarginal band proximally undulately bordered by blackish. 1 o from Sao Paulo. 



97. Calus-Group. 



Th. calus Godt. (158 d) is the only representative, distributed from Guatemala to the Amazon. Above cuius. 

 radiantly i¥o)7jAo-blue with a very broad blackish-brown costal margin, apex and distal margm, the costal 

 margin of the hindwing whitish, the distal margin narrowly black, only 1 tail. Beneath it is easily recognized 

 by the triangular, dark-brown costal-marginal spot on the ochreous-broAvn ground. The $ is smaller, much 

 duller, only in the disc of the hindwing light violet-blue, in the basal inner-marginal part of the forewing only 

 somewhat tinged in light greenish bluish-grey. 



98. Demonassa-Group. 



Th. demonassa Hew. (158 d) looks above like atritis (158 e), beneath it reminds us of calatia (157 f), demonassa. 

 but it has only one tail; the broad, red-brown discal bands are distalh'' bordered by black and white lines, proxi- 

 mally only on the hindwing by the short cellular streak. From Mexico to the Amazon.
