AGYRTRIA. 285 
both Agyrtria and Cyanomyia are unrepresented, though both occur on each side of 
that district. 
Though many of the species of Agyrtria are well defined, others are not so, and the 
specific limits of the latter are not clearly understood. 
The genus extends over nearly the whole of the tropical portion of South America, 
its northern limit being defined by that of A. candida in the middle of the Mexican 
State of Vera Cruz. Several species occur in Southern Brazil and Bolivia, but none 
seem to pass beyond the limits of the tropical forests. 
As a genus Agyrtria is very closely allied to Cyanomyia, and it is questionable whether 
they should be kept apart ; the tail of the latter is perhaps slightly more forked, but 
the difference is hardly material. In colour there is more diversity, as none of the 
members of Agyrtria have the crown glittering blue. Cyanomyia, on the whole, seems 
a natural group of species, and on that account had better be kept apart.

“Upper plumage of a dull bronzy dark green, the crown duller ; the upper tail-coverts of a lighter bronzy 
green, somewhat golden; the tail-feathers are dull bronzy green, all except the two central ones are 
broadly marked near their ends with dark purplish bronze, the tips being ashy grey; the throat and 
breast are glittering bluish green, middle of the abdomen white; the under tail-coverts are light olive 
margined with white; wings brownish purple; upper mandible black, the under yellow with the end 
black ; feet black. Length (skin) 3? inches, wing 2}, tail 12, bili 13.” (Lawrence, 1. s. ¢.)

We have never seen a specimen of this species, which Mr. Lawrence compares with 
A, linnwi (=A. viridissima, nob.), which it resembles in size and colour, differing in the 
tail being like that of A. nivetpectus. 
. The type was the only specimen of the species in the collection in which Mr. Lawrence 
found it, but there were many examples of A. candida.
