and sharp markings : 2 postdiscal lines on each wing, the proximal one tinged inside in brownish, the distal 

 one outside, the proximal line on the forewing straight, on the hindwing dentately broken, the distal ones on 

 both wings more crescentiform. Ecuador, Peru, Bolivia. 



Th. tnuatta Heiv. (157 h) may be inserted here. Above dull indigo-blue with broad blackish-grey mimita. 

 margins and a fine white marginal line before the fringes of the hindwing. Beneath grey with an oblique white 

 postdiscal line on the forewings, which makes an acute angle inward below the lower median vein and is proxi- 

 mally bordered by dark-grey; on the hindwings it is broken and forms a W at the proximal margin; the sub- 

 marginal line consists of small brownish spots, on which we notice inside whitish crescents ; 2 orange anal spots. 

 Brazil. 



Th. muattina Schs. differs from the preceding only by orange fringes of the forewing and an orange muaUina. 

 anal spot above. Castro (Parana). 



Th. aepeona sp. nov. (157 h). Very near to aepea, larger, above more lustrous blue with a narrow aepeona. 

 black distal margin, only the apex is a little broader black. Beneath the forewings are marked about the same, 

 on a lighter grey ground, on the hindwings, however, the postdiscal line begins in the middle of the costal margin 

 and runs straight to the lower median vein, in order to form a W then; the submarginal lines are more apart 

 from each other. Peru, Colombia. 



Th. renidens sp. nov. (157 h) greatly approximates the preceding; it is above lustrous ultramarine- renidem. 

 blue; the very broad blackish-brown apex runs in almost the same width close behind the cell as far as the 

 lower median vein, then on the latter along to the very narrow black distal margin, its proximal bordering 

 exhibits an intense violet lustre; the cell, on being exposed to an oblique light, is covered with indigo-blue 

 scales. The under surface likewise resembles the preceding, the ground-colour is just a little more brownish: 

 on the forewings the space between the submarginal lines, particularly towards the proximal margin, is filled 

 up by orange-brownish; on the hindwings the proximal submarginal line is more irregularly broken, between 

 the subcostal vein and the upper radial it protrudes more inwardly. Peru (Marcapata), Bolivia. 



Th. mimula sp. nov. (157 g) differs by its smaller size and above by its plainly brown giound-coloming ; mimuJa. 

 the fringes of the hindwing at the base white, distally black, close behind there is a black marginal line being 

 proximally bordered again by white. Beneath also very much like the preceding, pale olive-brownish gi'ey; 

 on the forewings the postdiscal line is situate close behind the cell and extends only to the lower median vein, 

 the proximal submarginal line is removed far inward, the distal one being sharply separated from the white 

 marginal line by an olive -brownish line. Hindwings marked about as in the preceding, but the distal margin, 

 particularly within the scope of the orange spots, is extensively white. Pachitea (Peru). 



90. Thespia- Group. 



Th. bosora Hew. (157 k) forms the transition from the preceding group to this group. Above dull bo.^ora. 

 blue, the apex and distal margin of the forewings broadly brown-black, in the disc a large, brilliant, ultramarine- 

 blue scent-spot; the marginal line of the hindwings black, proximally white; fringes likewise white, bordered 

 by black. Beneath brown with clear, light-blue, undulate, on the hindwings broken transverse lines and discal 

 streaks; on the forewings the postdiscal is proximally delimited below the lower median vein and runs very 

 obliquely towards the whitish anal angle. In the anal part and at the costal angle of the hindwings there are 

 red-brown spots. Exuador to the Amazon. 



" Th. thespia Heiv. (157) is above magnificently Morpho-hlue with a narrow black apex, beneath pecu- thespia. 

 liarly greyish -green with about the same linear markings as bosora, but the white discal streaks are absent; 

 also here a red spot is situate at the costal angle. The $ is above dull-blue, very broadly bordered by greyish- 

 black, beneath lighter, the red spots at the anal angle broadly flown together. Ecuador, Amazon. 



Th. photismos Drc. (157 h) is allied to the preceding ; above brilliantly bright sky-blue, with a moderately phoiismos. 

 broad black-brown margin. Under surface greenish-grey with the same linear markings as the preceding, but 

 without the red spot of the costal angle and with broadly flown together, red spots at the anal angle of the 

 hindwing. Ecuador (Sarayacu). 



Th. margarita sp. nov. (157 i) is another similar species, above at once to be distinguished by the margarita. 

 peculiarly mother-of-pearl green colour, exactly as in margaritacea (153 b), with a but extremely fine black 

 marginal line and black, on the hindwings proximally white fringes. Beneath almost like thespia, without 

 the costal-angular spot of the hindwing, the postdiscal line of which runs from the middle of the costal margin 

 almost straight through to the W. Bolivia (Rio Songo). 



Th. azurinus Btlr. (157 i) we append here, although there are no closer affinities on account of the a::inimts. 

 similar under surface. Above blue with a red-brown, oval scent-spot and a broadly black apex ; beneath greyish- 

 green with similar linear markings as the preceding, but on the forewings only 2; the}- are less undulate and 

 are, particularly on the hindwings, situate nearer to the border. Costa Rica.
