South-American typical specimens have no small spot beyond the band at the end 

 of the cell on the underside of the primaries, but in Central-American examples this 

 spot is clearly shown. As in certain South- American specimens its presence is just 

 visible, this character fails to distinguish Central-American from South-American 

 examples, and failing other characters we treat them all as of one species. T. phaleros 

 therefore has a very wide range in Tropical America, spreading from Guatemala 

 southwards through the Amazons valley to Guiana and South-east Brazil. A male 

 from Panima and a female from the Polochic valley are figured.

This species is very nearly allied to T. torfrida of Hewitson, the type of which is 

 before us, but the male is of a richer blue on the upper surface, and darker beneath, 

 and both sexes have a scarlet spot between the eyes on the forehead, of which we find 

 no trace in the allied form. T. coccineifrons is only known to us from three specimens, 

 two taken by Belt, one of which is before us, the other, a male, is in the Hewitson 

 collection, where it stands under the name of T. torfrida. The third, also a male, was
