THECLA. 63 



Eab. Guatemala, forests of Northern Vera Paz (F. D. G. & 0. S.).— South Ameeica, 

 Amazons valley l 2 and Guiana. 



We have a single male specimen of this species taken by ourselves in Guatemala in 

 the forest country north of Coban ; but it appears not to have been noticed elsewhere 

 within our limits. In South America it is an abundant species, especially in the 

 Amazons valley. The triangular spot on the costa of the primaries beneath renders 

 this insect easily distinguished.

Alis nigricantibus ; anticis area ad marginem internum et posticis fere omnino saturate cyaneis, stigmate 

 spurio ad cellulse finem : subtus cinereis, fascia communi discali nigra, extrorsum albo introrsum rubro 

 limbata, in posticis in maculas fracta, maculis quoque tribus basin proprioribus nigris, interne runs extrorsum 

 albo cinctis, linea altera submarginali nigra in posticis lunulata, lobulo anali puncto nigro, introrsum

Eab. Mexico, Milpas in Durango (Forrer), Jalapa (W. Schaus) ; Guatemala, Polochic 

 valley, Choctum (F. D. G. & 0. S.), Panzos, Teleman San Geronimo (Champion)', Costa 

 Rica, Cache (Bogers) ; Panama, Chiriqui and Calobre (Arce), Taboga Island (Cham- 

 pion). — South Ameeica, Colombia to the Amazons valley 3 , Guiana 4 , and South Brazil 3 . 



T. echion is not an uncommon species in Central America from Western Mexico to 

 Panama, and it is equally common throughout the tropical portions of South America. 

 The only difference that we notice in northern examples is that the orange spots near 

 the anal angle of the secondaries are much more clearly denned. 



We are rather doubtful if this species is rightly placed here, for the terminal portion 

 of the cell has the scales arranged somewhat in the manner of a stigma ; but the 

 position of the subcostal branches does not seem to be affected, as is the case when a 

 true stigma is present.

Eab. Guatemala, Polochic valley (F. D. G. & 0. S.); Costa Rica {Van Patten 12 ) ;

This species appears to be different from T. echion, and was described from a single 

 male specimen in Van Patten's collection, which is now before us. We have a single
