16 KHOPALOCEKA. 



Dr. Staudinger has sent us a single example from the neighbourhood of Chiriqui 

 which should bear this name rather than that of T. damo, the prevalent species in 

 the State of Panama ; it is of even deeper blue than normal T. marsyas, but has the 

 characteristic dark apex to the primaries. We notice a slight difference in it from true 

 T. marsyas in that there are two black spots at the anal angle of the secondaries instead 

 of one ; in this respect it agrees with T. damo, but the character is not of much moment, 

 as these spots vary considerably in size, and in some specimens are almost evanescent. 



T. marsyas enjoys a very wide range over nearly the whole of tropical South America 



T. augustula section ; primaries normal. (Species 11, 12.)

A single female specimen was contained in Van Patten's large Costa-Eican collec- 

 tion, and this was described by Messrs. Butler and Druce under the name of Mithras 

 augustinus, a name unfortunately previously applied to another species by Westwood, 

 necessitating the change made by Mr. Kirby 4 . We have since received a second 

 female example from Costa Eica and two males. Dr. Staudinger has a pair from 

 Chiriqui in his collection. The figures are taken from the Guatemalan specimen. 



T. augustula is evidently very closely allied to T. moniea of Hewitson, differing, how- 

 ever, in having the apex of the primaries beneath freely sprinkled with white scales. 



12. Thecla nepia, sp. n. (Tab. L. figg. 19, 20 <s .) 



S T. angustulce similis, sed alis supra multo magis argenteis, in posticis ad marginem externum extenso ; 



subtus antieis maculis ultra cellulam valde irregulariter positis, serie altera marginem externum propiore, 



area interna argenteo-caerulea baud brunnea.
