THECLA. By Dr. M. Draudt. 751 



Th. gaumeri Godm. & Salv. (148 d) is smaller, with only 1 greyish-brown scent-spot, black veins gawneri. 

 and, at the apex of the forewing, white fringes. Beneath the blue of the forewing is much more extensive and 

 fills up the whole cell ; the anal-angle-spots at the hind wing are much broader and quite green. The 5 is uni- 

 colorously greyish-brownish. Only from Mexico. 



Th. cynara Godm. & Salv. (148 c). Likewise resembling halesu.s, but beneath without the discal blue, cynara. 

 and the anal-angle-spots form a coherent, broad red-golden band. The margin of the forewings above much 

 broader black. Mexico. 



Th. atys Cr. (148 e). Larger than halesus, above more green, (J-scent-spot something like that of atya- 

 ■polybe, but the bordering of the proximal half, inclusive of the transverse vein, is leaden-grey. The 2 is more 

 silvery-green, the margins mach broader dull blackish-brown. Under surface brownish, with broad darker 

 veins and a dark band at the cell-end; at the base of the hindwing there are red .spots, behind them silvery- 

 green ones, 2 green macular rows in the black anal angle. Abdomen beneath orange-red. From Panama to 

 Colombia. 



Th. melidor Drc. (148 d, e) is above bluer than the preceding; beneath the dark cell-end-band is melidor. 

 absent, along the costa of the hindwing and of the proximal margin there are long red stripes. Abdomen beneath 

 vermilion. Captured in Peru in August. 



Th. cosa Heiv. (148 e). Smaller than «<^s, above deep metallic blue with somewhat broader blackish- coaa. 

 brown margins; beneath lighter brown, the basal half of the forewing darker with a dark, distally light-bordered 

 transverse band behind the cell, projecting far outwards below the lower radial vein; in front of the margin 

 on both wings dark transverse lines, a similar one at the cell-end of the hindwing. Brazil. 



Th. bacis Godm. ct- Salv. (148 d). Above likewise similar to atys, but of a more magnificent peacock- hacis. 

 blue; the scent-spot triple as in halesus, the middle part more yellowish-brown. Beneath similar to melidor, 

 but of a blacker fundamental tone; behind the cell of the forewing there is a series of green, small metallic spots, 

 interrupted on the lower radial vein ; the red stripes of the hindwings are of a magnificent carmine colour, between 

 them there are opalescent silvery-green stripes. Panama. — Staudinger described as vulnerata specimens vulneraia. 

 that are of a purer blue above, without a green reflection, with a narrower black margin; they are presumably 

 scarcely to be separated. 



Th. torfrida Heu\ (148 e) differs from all the preceding species by the absence of a scent-spot on torfrida. 

 the forewings, but instead there is a hair-tuft near the proximal margin of the hindwing beneath. Above dull 

 indigo-blue with a very broad, blackish-brown apex. In the black anal part of the hindwing there are 3 silvery- 

 green spots. Beneath almost like atys, but the light costal-marginal part of the forewing exhibits behind the 

 cell a dark-brown triangular spot; of the same colour is the apex and the space between the lower median vein 

 and the lower radial vein. Amazon. 



Th. coccineifrons Godm. <& Salv. (148 e) is very much alike, but immediately separable by the glaring coccinei- 

 carmine forehead in both sexes and the almost black under surface of the hindwings, from which the metallic r^ons. 



silvery- blue anal spots shine forth. From Mexico to Colombia. 



Th. carthaea Hetv. (148 g) approximates halesus, but it has no scent-spot; above magnificently deep carthaea. 

 peacock-blue with an extremely narrow black margin, only the apex of the forewing somewhat broader black; 

 in the black anal part of the hindwings are small, lustrous, metallic green spots. The under surface is almost 

 black, at the bases of the wings are carmine and green spots, at the costal margin of the forewing behind the 

 middle 3 green spots, in the anal part of the hindwing 2 short macular rows, the distal one green, the proximal 

 one more golden. Apparently found hitherto only in Mexico. 



Th. caranus Cr. (= ceranus Godt., pelops Cr., petus F., getus Wiv.) (148 g) is larger, otherwise above caranus. 

 like the preceding, perhaps of a somewhat purer ultramarine blue. Beneath the bases of the wings are much 

 more extensively deep carmine with numerous black, bluish-white-pupilled spots; the inner-marginal half 

 of the forewing is in the (^ violettish-blue, the ground-colour of the hindwings of a slight green lustre. From 

 Panama, Colombia, Guiana and the Amazon. 



Th. silumena Heiv. (148 g) has a rounder shape of the wings, above lighter greenish-blue, very silumena.- 

 brilliant, with a broader black apex and costal margin of the wings; beneath the ground-colour is lighter, reddish- 

 brown, the marking almost the same as in caranus. The forehead is read, in caranus almost black with silvery- 

 blue margins round the eyes. Colombia. 



Th. didymaon Cr. (148 g) is much smaller than the preceding with a considerably broader black apex didymaon. 

 of the forewing, above deep ultramarine-blue; beneath dark brown with 3 very conspicuous white spots of 

 the costal margin; the basal red is reduced. Brazil (Amazon, Sao Paulo). 



Th. neora Godm. <t Salv. (148 h) is still smaller, the blue more intense, still more reduced hy the neora. 

 extensive black, beneath the colouring and marking is just the same, but the small white spots are smaller 

 and narrower; forehead and the hairs on the thorax are rusty-red, in didymaon black. Mexico, Guatemala, 

 Colombia.
