764 THECLA. By Dr. M. Dkaudt. 



heera. Th. beera Heio. (154 c). More violettish-blue than the precedmg with a broader black margin and 



a larger scent-spot; beneath darker grey, the line-markings the same except the costal-marginal spot of the 

 hindwing bemg more streak-shaped; anal-angular spots smaller. Ecuador, Brazil. 

 exiguus. Th. exiguus Drc. (154 c) is marked like the preceding, but above more indigo-blue with a greenish 



tinge and ^vithout any scent-spot; beneath like the preceding. Surinam. 

 )astimonia. Th. castimonia Drc. (154 c) is above as blue as heera, but without the scent-spot and with but 



quite a narrow black distal margin without getting broader at the apex and with a distinct red anal spot also 

 above; the under surface is lighter with but little red at the anal angle of the hindwing. Colombia. 



pura. Th. pura sp. nov. (154 c) is very well to be included here. Above unicolorously blackish-brown, 



the hindwing at the anal angle with a small yellowish spot and a short white marginal line before the otherwise 

 black one. Beneath silvery-white Avith an extremely fine brownish postdiscal showing the same course as in 

 heera, but being placed somewhat more into the centre of the wing; also the small spot being placed distally 

 at the costal margin of the hindwing is very small and fine. There are no submarginals at all, only at the anal 

 angle stands a tiny yellow spot being above bordered by black, next to it the traces of a blackish crescent. 

 Described according to 1 (J from Sao Paulo. 



40. Meton- Group (Eekoa Kaye). 



meton. Th. meton Cr. (= metus Hbn., 2 augustus F.) (150 d) on the one hand resembles palegon, on the 



other hand it forms the transition to the following group. The ^J is above of a delicate light-lilac with a white 

 scent-spot, the $ almost white. The under surface is light-yellow to rusty-yellow with similar lines as in malina 

 but an eye-spot in the middle of the costal margin of the hindwing. From Mexico to Colombia and Brazil, 

 everywhere very common. 

 phrynisca. Th. phrynisca Burm., perhaps a form of the preceding, is somewhat smaller, the forewings above 



much more extensively black, beneath at the costal margin of the hindwing there is no eye-spot. Described 

 according to 2 $!j from Argentina (Corrientes). 



41. Mazurka-Group. 



atesa. Th. atesa Heic. (154 d) is above only in the proximal half of the wings brilliant blue, a round 



brown scent-spot stands already in the apical black. Beneath light-brown, very peculiarly marked in red- 

 brown with a large black eye-spot in the middle of the costal margin of the hindwing and a bronze-green dusting 

 at the anal angle. Panama to the Amazon. 

 mazurka. Th. mazurka Hew. (154 d) is perhaps not allied at all to the preceding, it is only placed here on 



account of the analogy of the marking beneath. Above the blue is still more reduced in the (^, a scent-spot 

 is absent. Beneath the eye-like spot at the costal margin of the hindwmg is much more developed and exhibits 

 2 blue pupils. The $ is above quite brown. Amazon. 



42. Narbal-Group. 



narbal. Th. narbal Stoll is unknown to me in nature. According to the figure and description it must be 



very closely allied to the following ; it seems to be a little larger and has beneath at the base of the costal margin 

 of the forewing and hindwing extensive red spots. Surinam. 

 amplus. Th. atnplus Drc. (150 k) is above brilliant-blue with a moderately broad black distal margin and 



a small, blackish-grey scent-spot in the upper cell-corner. Beneath the forewings are brown, unmarked, except 

 the narrow red base of the costal margin ; the hindwing exhibits in the middle of the costal margin a black, 

 distally white eye-spot, in front of the border a fine black, distally M^hite undulate line, a black anal-angular spot 

 and next to it a spot strewn with bluish-white. Venezuela, Amazon. 



Ophelia. Th. Ophelia Hew. (150k) is very similar, has above broader black margins and a larger scent-spot; 



beneath the costal-marginal eye-spot is absent, the base of the hindwing is more extensively red, a marginal 

 spot between the median veins is black. Bolivia, Amazon. 



hypsea. Th. hypsea Godm. dk Salv. (150 k) differs by a decidedly greener blue above, the distal margin, 



particularly of the apex, is much narrower black; the scent-spot exhibits at its lower margin a narrow light- 

 brown part. The under smface is as in ophelia, but the black marginal spot between the median veins is absent 



stictos. and replaced by only M-hite dusting. Panama. — stictos Drc. (151 a) from Colombia I can only take to be a 

 form of hypsea with a green upper surface, I do not find any other differences. 

 athymbra. Th. athymbra Heic. (150 i) is beneath exactly like hypsea, the bases of the wings more chestnut- 



brown, above the blue is reduced by the very broad black apex, the scent-spot is very large, double, proximally 

 red-brown, distally greyish-brown. Amazon (Itaituba). 



gemma. Th. gemma Drc. (151 a J"; the figure (150 k) denoted as gemnia-^ is wrong, it represents the upper 



surface of the allied rocena) resembles the following species from which it is discernible by the upper surface
