Hab. Nicaeagua, Chontales(.Z?^); Panama {Bible). — Amazons valley; S.E.Beazil 12 . 



We have a male specimen of this species from Nicaragua and a female from Panama, 

 lent us by Dr. Staudinger ; these agree with Brazilian examples and others from the 

 valley of the Amazons.

Alis viridi-cyaneis ; anticis costa late, dimidio apicali et margine externo toto, nigris ; posticis parte apicali et

 fusca albo late marginata, plaga mediana nitide stramineo granulata ; posticis linea sinuata ultra cellulam, 

 introrsum fusca extrorsum alba, altera submarginali indistincta fusca utrinque irregulariter limbata, 

 lobulo anali nigro, macula magna rubida inter ramos medianos puncto nigro. 



$ mari similis, sed alis supra cserulescentioribus : subtus dilutioribus. 



Hab. Guatemala, Polochic valley (F. D. G. & 0. S.); Costa Eica (mus. Staudinger).— 

 Amazons valley 1 . 



Hewitson described this species from Amazon specimens, with which three examples 

 obtained by us in the Polochic valley do not materially differ. We have seen no 

 specimens from other parts of Central America, except a male from Costa Eica lent us 

 by Dr. Staudinger. T. syedra belongs to a group of which T. sichceus of Cramer is 

 the best-known example ; from this it may at once be recognized by the discal patch 

 on the primaries beneath being straw-coloured instead of blackish brown. 



b 1 . No alar stigma ; secondaries with marginal filament. (Species 105-107.)
