T. syncellus is one of the most abundant species of this family throughout Tropical 

 America from Mexico through the Amazon valley to Guiana, and we have a large 

 series of both sexes. Individuals agree very closely with one another, except that the 

 outer black border of the primaries in the males of Mexican and Guatemalan examples 

 is narrower than in those from further south ; but as there seems to be considerable 

 variation in this respect, we are unwilling to lay too much stress upon it. T. syncellus, 

 so far as we know, has no close allies.

Alis nitidissime cyaneis, extrorsum anguste nigro marginatis ; anticis stigmate duplici ad cellulse finem et 

 infra earn plaga magna discali nigerrima; posticis lobulo anali nigro, maculis duabus parvis albis 

 instructo : subtus nigricanti-fuscis ; anticis maculis duabus parvis sub medio costse, altera triangulari 

 venis quinque partita apicem propiore et atomis variis ad medium marginis externi albis, macula parva 

 ad basin costse coccinea ; posticis fascia pallida valde indistincta ab angulo apicali ad medium marginis

 alis maris similibus, sed maculis et lineis omnibus multo magis distinctis. 



Eab. Guatemala, Vera Paz (Hague), Duenas (Champion). 



We have based our description of this species on two specimens, male and female, in 

 our collection, from Guatemala, the former sent us by Mr. Hague from Vera Paz, the 

 latter captured by Mr. Champion near Dueiias, both of which we figure. Dr. Staudinger 

 now sends us a male from the Volcan de Chiriqui which differs slightly from our type 

 in that the blue is a little less brilliant and the black spot on the primaries is consider- 

 ably more extensive. It is quite possible that this southern form should bear a separate 

 name, but we should like to see more examples before describing it. 



T. ochus, judging from the pattern of the wings beneath, is obviously allied to 

 T. paphlagon of Felder, of which we have three female examples in our collection. 

 The type of this species is said to be a male ; but, judging from what we find in 

 T. ochus, we think it possible that an error has been made as to the sex of this
