THECLA. By Dr. M. Draudt. 767 



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

 crescentiforni, blackish-grey one and between both a reddish-brown, fine row of scales. Tlie 5 i^ more greenish- 

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

 brown 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 liindwing, 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 scdcrUt. 

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

 from Mexico to Brazil. 



Th. thyrea Hew. (152f) is somewhat larger, the blue greatly reduced by very broad black luargins, ihyrca. 

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

 'poUhetes (152 c), but of a more intense violet, the proximal margin of the forewing extensirely yellowish-grey, 

 on the forewings the macular band in front of the border is absent. Abdomen beneath yellow. The $ is above 

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

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

 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 ciu/IH''^- 

 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 lui'^ a more obtuse and broader black stiymafos. 

 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 Hew. (152e) looks above like a small poUbetes without a black median spot, the scent- on/la. 

 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 B.sd. (= psyche Bsd.) (152 d) for which Scudder has established the genus Eupsyche, m-album. 

 is more slender, otherwise above like orgia (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 brown-bordered 

 lines with a distinct W at the proximal margin. The red anal-angular s]iot 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 orgin (152e), but it is somewhat more greenish-blue o.'itia. 

 and has an c^xtensive 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 a,re well developed. Brazil. 



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

 blue, the scent-spot more oblong, red-brown. The under surface, jiarticularly of the hindwings, is darker brown, 

 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, dee])er blue, hecate. 

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



Th. hewitsoni Ky. (= ira Hew.) (152d as ira) greatly resembles ostia above, but the distal margin )ieu'it.'io)ii. 

 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.-Sch&ff. (152 d) is smaller, more coiuj^act, with rounder hindwings, coloured like pundum. 

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

 in front of the border of the forewing quite obsolete, on the hindwing removed veiy far towards the margin, 

 the red spots intense, mostly connected. In the ^ 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 nihr. 

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

 and more coherent. Amazon.
