Heterorhina leucosticta. 
Cyphorinus leucostictus, Can. Wiegm. Archiv, 1847, 1, 206 (Guiana and 
Mexico).—Scuarer, P. Z. S. 1858, 63, 96.—Lawrence, Ann. N. Y. 
Lye. VII, 1861, 320 (Panama). 
Hab. Isthmus of Panama, to Guiana and Ecuador. 
A specimen from Panama, in Mr. Lawrence’s collection, labelled 
0. leucostictus, has the breast and belly pure white like the throat, 
and the white spots on side of head larger. The size is considerably 
less than in prostheleucus, while the tarsi are longer. The shoulders 
are less spotted with white. 
Another specimen from the Napo (32,693), labelled C. leucostictus, 
differs from the last in having a longer, slenderer bill. The whole 
top of head is black; the black bars on the inner or superior secon- 
daries are quite obsolete, those on the outer webs of the exterior 
ones being changed to dentations. The spotting of the shoulders is 
restricted to the alular feathers and edge of the shoulders. 
Cabanis, in his description of C. leucostictus, gives Guiana and~ 
Mexico as localities, thus referring also to C. prosiheleucus. The 
small size of the specimen described, and the whiteness of all the 
under parts, would appear to show that the description was based 
on the Guiana specimen.
