Hob. Costa Eica, San Jose {Hoffmann ^ ^), La Candelaria {v. Fmntzius ^ «), Volcan de 

 Cartago {E. JrcS ^, J. Cooper ^, Boucard 7), Faldas de Irazu ^, La Palma {Zeledon) ; 

 Panama, Volcan de Chiriqui {Arce ^). 



This beautiful species was discovered by the late Dr. Hoffmann in Costa Rica, and 

 was described by Cabanis and Heine in 1860 from the single specimen sent by him to 

 the Berlin Museum ^. This specimen also formed the subject of Gould's plate ^. A few 

 years afterwards our collector, Enrique Arce, procured a series of specimens from Costa 

 Eica, and subsequently others from the Volcan de Chiriqui, the sexes of each specimen 

 from the latter locality being noted on the label. We thus learn that there is no 

 tangible difference between the sexes of this species, the female being hardly less 

 brilliant than the male. At one time it was supposed that the bird described by Gould 

 as Anthocephala castaneiventris (a female Oreopyra) was the female oi Panterpe insignis^, 

 but this view has, we believe, been now definitely abandoned. 



The. range of P. insignis seems to be very limited, and probably does not extend 

 beyond the upland zone of forest which occupies the higher volcanoes of Costa Rica 

 and Chiriqui. Zeledon gives its Costa Eica habitat as the slopes of the Volcan de 

 Irazu, which is another name for that of Cartago. The same collector has sent a 

 specimen to the United States National Museum from La Palma.

Of the twenty-two species included in this genus only two occur within our limits, 

 one of them being the widely-ranging A. Candida, which extends from Eastern Mexico 

 to Nicaragua, the other being A. lucice, the only known specimen of which came from 

 Honduras. It is somewhat remarkable that in Costa Rica and the State of Panama
