750 THECLA. By Dr. M. Dratjdt. 



zava. Th. zava Heio. (153 b) which I know only from the author's description and figure, is ranged here. 



Above blue with broad dark-brown margins and a dark-brown discal spot. Beneath brown, darker undulated 

 with 3 transverse bands and whitish-watered spots of the costal margin of the forewing before the centre and 

 at the apex. No habitat mentioned. 



13. Anna-Group. 



anna. Th. anna Drc. (147 d) is an entirely isolated animal. Above metallic-blue, with bread blackish- 



brown margins. Beneath the forewings are brownish-grey, towards the margin strewn with whitish, in the 

 disc opalescent blue; the hindwings are brown, densely strewn with whitish and darker scales and marked 

 with black spots the arrangement of which approximates the most the wiars^/a-s-group; they exhibit 2 rather 

 long and broad tails. Described according to 1 example from Colombia. 



14. Mavors-Group. 



mavors. Th. mavors Hbn. (148 b as triquetra). The <^ is above bluish-green with a large brown scent-spot, also 



beneath green with fine black transverse lines, at the anal angle of the hindwing no distinct W. The $ is above 

 and beneath plainly coloured in brown. The hindwings bear 2 tails. From Mexico through the whole of Central 

 America to Colombia, Guiana and the Amazon ; everywhere very common, but apparently not going up higher 

 than 3 to 4000 ft. 

 triquetra. Th. triquetra Heiv. (152 b) differs by having only one tail and a somewhat duller bluish-green colour 



above; beneath also in the ^ the ground-colour is discoloured brown, only sparsely sprinkled with silvery- 

 green scales, and the lines run somewhat differently. Panama, Surinam, Brazil. 

 ella. Th. ella Stgr. i. I. (148 b, as jnavors) is easily discernible from the two preceding by the absence 



of the scent-spot, the under surface being quite brown also in the ^J and the distinct W at the anal angle of 

 the hindwing. The hindwing bears 2 tails. Colombia, Ecuador. 

 paupera. Th. paupera .FWr. (148 b) from Bogota seems hitherto to be extremely rare. It resembles e?Za above, 



harietta. but it is of a more lustrous dark-green, beneath brown, marked like triquetra, without a distinct W. ■ — harietta 

 Weeks from Bolivia is probably only a variety of colours, above lustrous blue, towards the base warming into 

 greenish. 



15. Polybe-Group {Atlides Hbn.). 



inachus. Th. inachus Cr. (= baeton Sepp) (148 f). A M'ell-known species, above in the (J metallic indigo-blue 



with a moderately broad blackish-brown margm; the large, long, greyish-brown scent-spot is parted m two 

 by the transverse vein. Hindwing at the anal angle with Mhitish-grey hair and variegated with silvery-green 

 scales. The $ is in the basal half dull greenish bluish-grey, distally blackish-brown. Beneath brown, in the 

 basal half of the forewing and the inner-mai'ginal half of the hindwing green, in the basal area of the hindwing 

 carmine with a large black eye-spot being narrowly bordered by silvery-green ; abdomen beneath orange-yellow. 

 carpophora. From Panama to East Peru, Guiana and the Amazon. — carpophora Hew. (148 f) is the northern form and 

 but little different; beneath, on the whole, darker brownish-black with less green and red, the black eye-spot 

 mostly smaller and, instead, more broadly bordered with silvery-green. Mexico and Guatemala. 

 carpasia. Th. carpasla Heiv. (148 d) is above similar, but with decidedly black veins; the proximal brown part 



of the scent-spot is twice as long as the distal black part. Beneath the brown wings are black-veined, without 

 any transverse lines, only before the anal angle of the hindwing several silvery-green macular bands; in the 

 red basal part there are 3 black spots with silvery-green pupils. Abdomen beneath orange-red. Mexico, Guate- 

 inala. 

 polyhe. Th. polybe L. (= atys $ Cr., scamander Hbn.) (148 c). c? above turquoise-green, ? duller, more 



bluish-grey, with black veins running radiatingly into the broad blackish-brown border. Scent-spot double, 

 the proximal half mostly lighter brown than the distal black half, the transverse vein separating both is likewise 

 covered with modified scales of a greyish-blue colour. The under surface is olive in the cj, in the $ more 

 yellowish-brown, with black veins, the disc of the forewing in the (^ opalescent blue. From Mexico to South 

 Brazil and Argentina, but everywhere rare. 



halesus. Th. halesus Cr. (= dolichos Hbn.) (148 c) is above metallic greenish-blue with a moderately broad 



black distal margin and a very broad black anterior angle of the hindwing. Scent-spot triple: between the 

 smaller proximal brown part and the irregular larger distal part there is, on the transverse vein, a brown oval 

 surrounded by single blue scales. Beneath bro^Ti; below the median of the forewing and along the proximal 

 margin of the hindwing opalescent-blue stripes; at the base of the forewing 1, at the base of the hindwing 2 red 

 spots, at the anal angle some golden and silvery-blue spots. Abdomen beneath orange. Widely distributed 



jvanita. .from the Southern States (Florida-California) to Mexico and Costa Rica. — Northern specimens, juanita Scudder, 

 exhibit chestnut-red spots between the anal-angle-spots.
