in the upper cell-corner is a round, brownish-grey scent-spot varying greatly in its colour, close below it a smaller, 

 crescentiform, blackish-grey one and between both a reddish-brown, fine row of scales. The $ is more greenish- 

 blue, with a much broader, blackish- brown border. The under surface is extremely variable, lighter or darker 

 bro^Ti with a violet lustre, on the forewing an arcuate or straight line or row of spots, in front of the border 

 blackish spots; on the hindwing, beside the basal dot, a curved row of spots, with a distal silvery-blue tinge, 

 behind it a row of spots and between the tails a red, black-pupilled spot. ■ — In sedecia Hew. (152 i) the line sedecia. 

 of the forewing is straight, distally, like all the spots anyhow, with a broader bluish-white tinge. Common 

 from Mexico to Brazil. 



Th. thyrea Hetv. (152 f) is somewhat larger, the blue greatly reduced by very broad bla.ck margins, thyrea. 

 without the large black median spot, the single brown scent-spot surrounded by black. Beneath almost like 

 polibetes (152 c), but of a more intense violet, the proximal margin of the forewing extensively yello'nash-grey, 

 on the forewings the macular band in front of the border is absent. Abdomen benea.th yellow. The ^. is above 

 dull greyish-brown with broad blackish-brown margins, the under surface more grey with an orange tinge.

Th. arindela Hew. (152 b) has above more extensive greenish-blue, so that the scent-spot is situate arindela. 

 in the ground-colour. Beneath the white macular lines are more developed, on the forewing there are beside 

 the postdiscal yet two nearer to the proximal margin. Abdomen above greenish-blue, beneath orange. Nicaragua. 



Th. epytus Godm. <£■ Salv. (152 c) resembles above more thyrea (152 f) by the scent-spot being situate epytas. 

 in the black, beneath the forewings are without markings, the hindwings as in orgia (152 e) with a dark discal 

 streak of the hindwing. Panama. 



Th. stigmatos Drc (152 b) resembles arindela above, but it has a more obtuse and broader black stigmatos. 

 apex of the forewing; the under surface is almost like in orgia, but the forewings are without any markings 

 at all. It originates from the interior of Colombia. 



Th. orgia Heiu. (152 e) looks above like a small polibetes without a black median spot, the scent- orgia. 

 spot is remarkably light. The ground-colour of the under surface is more yellowish-brownish, otherwise equally 

 marked. Common from Mexico to the Amazon. 



Th. m-album Bsd. (= psyche Bsd.) (152 d) for which Scxjdder has established the genus Eupsyche, m-album. 

 is more slender, otherwise above like 07'gia (152 e), but with a distinct red anal spot of the hindwing and somewhat 

 lighter blue. Beneath also marked the same, but the postdiscals form coherent white, proximally bro\\Ti-bordered 

 lines with a distinct W at the proximal margin. The red anal-angular spot is large and sends a connecting stripe 

 towards the red tail-spot, between both there is bluish-white dusting on a blackish-brown ground. The range 

 of the species extends from the Southern States (New Jersey, Wisconsin) to Venezuela. — The larva lives on 

 Quercus and Astragalus. 



Th. ostia Hew. (152 d) likewise resembles above orgia ^152 e), but it is somewhat more greenish-blue ostia. 

 and has an extensive black apex of the forewing. On the under surface the white macular bands are moved 

 much nearer to the border, and on the hindwings they run more uniformly bent, parallel to the margin; the 

 red spots are well developed. Brazil. 



Th. vibidia Hew. (= socigena Hew.) (152 c) greatly resembles the preceding, above darker purple- vibidia. 

 blue, the scent-spot more oblong, red-brown. The under surface, particularly of the hindwings, is darker broA^ii, 

 and here the proximal white macular band begins at the costal margin with a distally removed spot; the red 

 spot between the tails appears to be placed more inside. Mexico to the Amazon. 



Th. hecate Godm. <& Salv. (154 d) from Mexico and Nicaragua is very closely allied, deeper blue, hccaie. 

 with a more distinct stigma. The forewings bear a discal line beneath. 



Th. hewitsoni Ky. (= ira Heiv.) (152 d as ira) greatly resembles ostia above, but the distal margin Jiewifsoyii. 

 of the hindwings is only quite narrowly black, the scent-spot is smaller. Beneath the markings are more obsolete, 

 the white lines finer, the forewings without any markings at all. Mexico. 



Th. punctutn H.-Schaff. (152 d) is smaller, more compact, with rounder hindwings, coloui'ed like punctum. 

 m-album, but without any red at the anal angle. Beneath coloured like 7n-album, the white macular band 

 in front of the border of the forewing quite obsolete, on the hindwing removed very far towards the margm, 

 the red spots intense, mostly connected. In the (J the white dot in the middle of the costal margin of the hindwing 

 is very minute or it is absent altogether, in the $ being above dull greyish-blue it is more distinct. Guiana to 

 the Amazon. 



Th. nitor Drc. (152 h) is perhaps only an aberration of punctum with beneath unmarked forewings nitor. 

 and almost absent submarginal spots on the hindwings, on which the proximal macular band is more distinct 

 and more coherent. Amazon.
