PACHTEHAMPHUS. 125 



exceptions in the latter respect, the sexes being alike, and only to be distinguished by 

 the form of the second primary in the male. 



Mr. Eidgway gives us a character whereby to distinguish Platypsaris {=Hadro- 

 siomus) from Pachyrhamphus, by the covering inner surface of the posterior half of the 

 tarsus, which in the former, he says, is covered with a series of large scales, but in the 

 latter is naked ; this seems to hold good when ff. aglaice and P. major are compared, 

 but nearly all the other species of Pachyrhamphus agree in this respect with Hadro- 

 stomus, so that this character does not seem to be trustworthy for diagnostic purposes.

Hob. Costa Eica, Candelaria {Boucard ^). — Colombia ^ ^ ; Ecuador. 



This species is included here on the authority of M. Boucard, who obtained a single 

 specimen at Candelaria in Costa Rica during his visit to that country in 1877. It 

 occurs in the Colombian State of Antioquia, is commonly seen in the trade collections 

 made in the vicinity of Bogota, and is also found in the northern districts of Ecuador. 



P versicolor stands alone in the genus, no other species having the under surface 

 barred in a similar manner. 



Nothing as to its habits is on record.
