780 THECLA. By Dr. M. Draudt. 



panchaca. Th. paiichaea Hetv. (= scoteia Heiv.) (155 g) is above rather similar, in the (^ bkier, the hindwings 



of a rounder shape. Beneath the transverse lines are fine, nearer to the margin and parallel to it, the red spot 

 on the tail smaller. Amazon, Minas Geraes. 

 pion. Th. pion Godm. & Salv. (155 g) looks above like the preceding and has the same subcostal hair-pencil 



and the submedian hairing on the hindwings; beneath it is duller and more indistinctly marked, the small red 

 spot quite insignificant. Perhaps it is a form of panchaea and its northern representative. Distributed from 

 Mexico to Panama. 

 oppia. Th. oppia Godm. & Salv. (155 g) is above much more extensively blue and, on the hindwings, it 



has a distinct, small, red anal spot. Above the .subcostal hair-pencil of the hindwing is a black scent-spot. Beneath 

 it is much more abundantly marked in white, also before the margin. Described from Mexico. 

 piplea. Th. piplea Godm. <!• Salv. (= subobscura Lathy). Allied to pzow (155 g); the (J with the small hair- 



spot on the upper surface of the hindwing near the base of the subcostal vein. But beneath the wings are of 

 a more intense colour than in pion. The dark-red anal spot of the hindwing is much larger, the two transverse 

 macular stripes nearer to each other. West Indies: St. Vincent (Grenada). 



martialis. Th. martlalis H.-Schaff. (155 g) on the whole resembles coelebs above, but it is of a duller sky-blue 



and immediately distinguishable by the large, indistinctly defined, discal spot. Beneath the markings are 

 likewise very similarly arranged, but instead of the rows of moonspots there are rather broad white lines. Florida, 

 Cuba, Jamaica. ■ 



70. Strephon-Group. 



sirephon. Th. strephotl F. (= sichaeus Cr.) (151 d). Upper surface magnificently cornflower-blue with a 



very broad black apex with indistinctly visible scent-scales; the anal angle of the hindwing above bordered 

 by white, in the black lobe a small red spot. Beneath brownish-grey, the proximal margin of the forewing whitish 

 with a large, oval, brown scent-spot below the median, covered by the convex, bulging margin of the hindwing. 

 The postdiscal lines are white, running on the forewing from the middle of the costal margm straight to the 

 lower median vein, and from here as far as the proximal margin in the shape of a W; submarginally placed 

 is a row of brownish moon-spots, bordered on both sides by white, between the median veins and at the anal 

 angle interrupted by red spots. Amazon. 

 cyllarus. Th. cyllarus Cr. (= strephon Godt. nee F., cyllarissus Hhst.) (151 f) is above the same, only somewhat 



more greenish, and the angle between the median veins on the forewing is still blue, in strephon already situate 

 in the apical black. Beneath much lighter, the markings duller and finer, parallel to the margin. The 2, as 

 almost all of this group, is above much duller and the blue more confined, the shape of the wings rounder and 

 deltciae. broader. Brazil to Peru. — deliciae Drc. (151 i) seems to be based only upon an aberrative specimen in which 

 all the black markings beneath are absent; taken in North Brazil. 



porphyrUis. Th. porphyritis Drc. (151 h) does not differ from strephon above and it is just as dark beneath, but 



the marking is parallel to the border as in cyllarus, the white colour very prominent, the scent-spot much smaller, 

 nut-brown and nearer to the base; the disc exhibits a silky lustre. Brazil (Tapajoz and Para). 

 perola. Th. perola Heio. (151 g, h). Above like cy^/ants, distinguished on the hindwing by the broad blackish- 



brown costal margin shining as if polished. Beneath the white markings are strongly developed, the po.st- 

 discal line more strongly and irregularly broken, the blackish-brown scent-spot extends as far as the median. 

 Amazon, Bolivia. 

 tyriam. Th. tyriam Drc. (151 h) differs from the preceding above by the reduced blueof theforewings, which 



does not reach the anal angle, but is cut off by the broadly black distal margin ; the costal margin of the hindwing 

 is likewise polished. The under surface is lighter, the scent-spot smaller, lighter straw-coloured than the ground. 

 Brazil (Para), Bolivia. 

 irebonia. Th. trebonia Heiv. (151 e) differs from the preceding by the large scent-spot in the distal half of the 



cell; the ground-colour is a lighter, greener blue. Beneath as in perola. Ecuador. 



iderkndanie. Th. uterkudante Drc. (151 e) has above the blue of strephon (151 d) and no scent-spot; beneath it differs 



from the preceding by a straw-coloured scent-spot and much broader black and white transverse lines, the 

 proximal one of which begins at the costal margin with a large triangular spot. Colombia. 



osirinus. Th. ostfinus Drc. (151 f). X\)Ove\i\ie strephon, but without the red spot in the anal angle of the hind- 



wing. The ground-colour beneath is of a decidedly greenish tinge and the scent-spot is absent altogether 

 Cayenne. 



phoster. Th. phoster Drc. (151 f) does not differ from cyllarus above. The ground-colour beneath is much 



darker and lustrous; the scent-spot is much larger, but it does not contrast in the colour; the postdiscal band 

 is very prominent; the red spots are very strongly developed. Surinam, Colombia (Muzo).
