Additional specimens from both Honduras and Costa Rica received since P. a. 

 hypophxus and P. a. obscnirus were described show that the characters upon which 

 the latter was based are inconstant, specimens from the two countries being practically 

 alike. 



f> Some females from Guatemala (precise locality unknown) are indistinguishable 

 from Honduras specimens and probably belong to the present form. 



c These references, which are all apparently based on a specimen collected by 

 Ellendorf, may possibly pertain to P. a. latirostris. The exact locality of the Ellen- 

 dorf's specimen is not known, however, and therefore only an examination of the 

 specimen itself will make its correct allocation possible.
