84. Odinus-Grouji. 



Th. odinus Godni. & Salv. (157 e) is undoubtedly closely allied to aholiba (157 d). Above lustrous odlnus. 

 sky-blue, broadly margined in brownish-black with a blue submarginal line in the anal part of the hindwing. 

 Beneath the forewings are marked as in aholiba, only the postdiscal line is more undulate and in the light inner- 

 marginal area beneath the lower median vein it turns back with a distally open, obtuse angle. The hindwings 

 are likewise alike, but more irregularly marked, the light-blue lines thicker and more luminous; at the costal 

 angle of the hindwing there is often some red-brown dusting. Panama to Colombia 



85. Corolena-Group. 



Th. corolena Hew. (152 k) is above deep violet, with a broad black apex and distal margin and a corolemi. 

 small light-grey scent-spot in the cell. Beneath deep purple-brown, the forewings unmarked, the hindwings 

 with the postdiscal and submarginal lines being brought very near to each other and very near to the border; 

 the former consisting of white, proximally black, small streak-spots, the latter of dark lunae bordered on both 

 sides by white dusting. Abdomen beneath yellowish white. Guiana. 



Th. viola sp. nov. (157 e) is very similar, above deep purple-violet, so that the dark apex scarcely viola. 

 contrasts with it, differing by a very large double scent-spot, the proximal portion at the cell-end deep blackish- 

 brown, the distal part greenish slate-grey; in the anal lobe a large red spot. Beneath similarly greasy lustrous 

 lilac-brownish-grey, marked just the same on the hindwings, but with a much smaller red spot of the tail and 

 also on the forewings a postdiscal line forming an angle inward below the lower median vein in the lighter grey 

 mner-marginal area. Abdomen beneath white. Amazon. 



Th. guapila Schs. (157 e) differs above by a much purer metallic blue, a considerably smaller scent-spot guapUa. 

 the proximal part of which is small, black, the distal part being oval and brownish; in the anal lobe no red. 

 Beneath slate-grey, on the forewings the postdiscal line extends only as far as the lower median vein, on the 

 hind%Aings it is displaced more inward, otherwise of the same shape. Abdomen beneath yellowish-white. Costa 

 Rica. 



86. Galliena-Group. 



Th. galliena Heiv. (157 e) is above deep indigo-blue with moderately broad black margins and a red gaUicna. 

 anal spot of the hindwing. Beneath dark red-brown, the postdiscal lines placed near the border, darker brown, 

 with a fine, white, distal tinge, on the forewings, however, but very little; the submarginal line less distinct, 

 darker brown ; between the tails a deep red spot pupilled in black ; between it and the black anal spot a white- 

 dusted spot. Distinguished from the species of the preceding group merely by the absence of the scent-spot. 

 Nicaragua to Brazil. 



Th. nisaee Godm. ds Salv. (154 e) is very similar, but above violettish purple-blue, beneath the sub- nisaee. 

 marginal line of the hindwing has a whitish tinge analwards. Panama to Colombia and Bolivia. 



Th. lophis Drc. (157 e) differs from nisaee by a more metallic, purer blue and a more broadly black lophis. 

 apex of the forewing. Beneath easily recognizable by an orange-red spot at the costal base of the forewiug. 

 Expanse of wings: 35 mm. Colombia. 



87. Orcidia-Group. 



Th. orcidia Hew. (157 f). Above dull incligo-blue with a narrow black margin and a small red anal orcidia. 

 spot, beneath light brown, the base, the proximal margin of the hindwing, and two broad postdiscal bands 

 dark-brown. On both wings are indistinct double cell-end-streaks; the postdiscals are situate at the proximal 

 edge of the brown bands, copper-red, on both sides bordered by black and on the hindwings distaUy yet bj- 

 white; at the border are darker submarginal lunae and spots, at the anal angle 2 narrow red crescents. The 

 width of the red po.stdiscal varies, it may also be absent altogether. Occm'ring from Mexico to Brazil. 



Th. myrsina Hew. (157 f ) is above just the same, beneath the basal spot is more sharply defmed, the myrsina. 

 postdiscal lies on the forewings outside the brown median band, on the hindwings inside, without the red border- 

 ing; on the forewing it is displaced far inward below the lower median vein. Nicaragua to Colombia. 



Th. tabena Godm. ds Salv. (157 f) looks beneath like myrsina, but above it is one-coloured brown, tabeua. 

 From Mexico and Guatemala. 



Th. tarpa Godm. <& Salv. (167 e) resembles tabena and is above brown like it, but it is consid-erably iarpa. 

 smaller and has beneath a white discal line, also the distal margin of the forewing is whitish. Mexico. 



Th. taminella Schs. is above one-coloured brown with an orange anal spot, beneath very much like iamincUa.
