THECLA. 73 



This is an abundant species in Central America from Guatemala southwards through 

 Costa Rica (whence the types were derived) to the State of Panama, and thence 

 throughout Tropical South America to Brazil. The type and Central-American speci- 

 mens have the black spot between the median branches of the secondaries broadly 

 edged with red ; this colour in South- American examples becomes a reddish brown, but 

 the difference is very slight and hardly of specific value. The southern form has been 

 described under the name of Thecla lugubris by Herr Moschler.

Alis indicia ; posticis medialiter nitide cyaneis : subtus obscure brunneis ad basin pallidioribus, linea com- 

 muni discali nigra extrorsum albido limbata, marginem posticarum internum versus angulata, lobulo anali 

 nigro, maculis duabus juxta eum nigris, proxima albo sparsim atomata. 



5 alis supra omnino brunneis ; subtus alis maris similibus. 



Hab. Guatemala, Polochic valley (F. D. 0. & 0. S.), Cubilwitz (Champion) ; Nica- 

 kagua, Chontales (Belt *) ; Panama, Bugaba (Champion), Line of Railway (M'Leannan). 

 — South Ameeica, from Colombia to the Amazons valley and South-eastern Brazil 1 . 



Hewitson's type-specimens came from Brazil and Nicaragua, from which widely 

 separated localities we, too, have examples, as also from many intermediate points. 

 All these specimens agree closely with one another, but have a slight difference in the 

 tint of the blue on the secondaries, the Guatemalan example being the darkest and one 

 from Colombia the palest and most brilliant.

T. xenetce similis, sed alis supra plerumque saturatioribus colore posticarum cyaneo magis restricto : subtus 

 maculis nigris ad angulum analem rubro introrsum late circumcinctis. 



Hab. Panama, Chiriqui (Trotsch), Panama city (Bibbe). — Amazons valley. 



We have no Central-American specimens of this species, but numerous examples 

 from the valley of the Amazons ; these show considerable variation in the amount of 

 blue colour on the secondaries. Dr. Staudinger has lent us two males from the State 

 of Panama which also differ from each other in the same particular, that from Panama 

 having more blue than any of the specimens before us, and consequently has a narrower 

 dark border, but the common character of the red margins to the black spots near the 

 anal angle of the secondaries beneath connects them together and serves to separate 

 them from T. xeneta. 



The Chiriqui specimen is figured.
