792 THECLA. By Dr. M. Draudt. 



straight, on the hindwings on the lower radial vein broken, from here proximally bordered by black. Expanse 

 of wing.s: 20 mm. Castro (Parana). 



canacha. Th. canacha Hew. (167 f) resembles tahena above, the ^ is brown, the 9 on the hindwings blue-tinged; 



beneath likewise very similar, the bro\^ai band on the forewing very narrow, easily recognizable by the donble 

 rows of small arcuate spots before the distal margin of the hindwing ; the postdiscal lines are proximally tinged 

 by an orange bro^^mish. Venezuela, Colombia. 



arza. Th. arza Hew. (157 f) is above likewise brown like the preceding, the ground-colour beneath, however, 



is yellowish-white, v,'\i\\ which the broad brown bands and the basal area are sharply contrasting ; in the hindmngs 

 the white, dark-tinged postdiscal line penetrates analwards into the brown band. Mexico to Panama. 



parahis. Th. paralus Godm. ds Salv. (157 f) greatly approximates arza, but it is smaller, and the ground-colour 



beneath more a dirty grey, the dark bands are removed more inward, more faded. Guatemala, Costa Rica. 

 calaiia. Th. calatia Hew. (157 f) deviates from the preceding by. its orange-yellow under surface; the white 



postdiscal line traverses the brown band on both wings; the distal margin remains one-coloured yellow. Guate- 

 mala, Nicaragua. 

 munis. Th. aunus Cr. (157 f ) we add yet to this group, though it deviates greatly. Above indigo-blue. The 



under surface is yellowish-white, towards the margin warming into lilac-brown; the base of both wings and 

 a large triangular spot at the costal margin of the forewing are brown; the hindwings exhibit a double, brown 

 discal streak, the postdiscal line is strongly broken and makes a bend inward on the forewing below the lower 

 i'adial vein; small orange anal spots are merely indicated. Guiana to Brazil. 



duma. Th. duma Heic. (157 g). We here append this quite isolated animal. Above dark-brown, with a blue 



tinge, beneath yello\\'ish-white, large median spots, broad postdiscal bands, and the distal margin brown. Bogota. 



88. Maeonis- Group. 



maeonis. Th. maeoiiis Godm. cfc Salv. (157 g) is above light-blue with a broad black apex, beneath rusty-brown 



and distinguished by the postdiscal being moved as far as into the middle of the wing; the lines are white, the 

 proximal line inside, the distal one outside bordered by red-brown, at the anal angle of the hindwing by black; 

 the anal lobe and spot of the tail black, proximally bordered by a broad red-brown, between them a black 

 spot being inside dusted in white. Mexico, Guatemala. 



89. Tema-Group. 



ie7na. Th. tema Hew. (157 g). Above dark-brown, the forewing at the proximal margin and the hindwing 



in the disc dusted in blue. The under surface is chocolate-brown, each of the wings with 2 white transverse lines 

 in the middle and behind it, on the forewings straight, on the hindwings broken and dentate; each wing besides 

 with 2 indistinct, white, antemarginal lines. The hindwings have two fine tails, above them and at the anal 

 angle the usual, small red spots. Amazon. 



paron. Th. paroti Godm. & Salv. (157 g, h) on the whole resembles the preceding, but it has only one tail 



and the under surface is more greenish black instead of brown. Guatemala. 



cradides. Th. heraclides Godm. & Salv. (157 g) greatly resembles faron, but above it is metallic bluish-green, 



with a large, dark discal spot, behind which the wings exhibit a black reflection; the shape of the wings is a 



little more obtuse. Costa Rica. 

 serg'nis. Th. sergius Godm. tfc Salv. is above almost the same, but the discal spot is of a radiant blue, the black 



distal margin broader. This species and the preceding exhibit also a resemblance to the trochus- and ronos- 



group (p. 756), but they greatly deviate by the tails and the scent-spots. 

 dodava. Th. dodava Hetv. (157 g) we include in this group. It is above lilac with a large, black discal spot 



behind the cell; beneath grey with whitish discal streaks and dentate lines, in the ^J the proximal margin of 



the forewing is blue. Panama. 

 vara. Th. nora Jones (157 g) is very closely allied, larger, more slender, more purple-violet, the distal margin 



and apex only narrowly black, the scent-spot is the same. The under surface is more blackish, the white transverse 



lines are more subdued, on the hindwings proximally bordered by orange, more strongly broken, above the upper 



median vein displaced outward, between the orange anal spot a black, white-strewn spot. Brazil (Castro; 



Amazon). 



aepea. Th. aepea (157 g, h) is a small, above dull ultramarine-blue species with broad blackish-grey margins; 



the $ is duller and lighter blue, the hindwings almost entirely brownish-grey. Beneath light-grey, with clear
