@ Two specimens. 
Iam somewhat doubtful as to the validity of this form, which at present rests on two 
specimens. In these the color of the throat is distinctly different from that in the 
only two adult males of true DL. amethystinus now before me (from Vera Cruz), being 
a more decided purple or less pinkish (nearly phlox purple, the color in L. a. ame- 
thystinus being rather more pinkish than solferino). A specimen from San Cristébal, 
Chiapas (provisionally referred to L. a. salvini, though by no means typical of the 
latter) has the throat colored precisely as in these specimens from western Mexico, 
while one from Mt. Zempodltepec, in northeastern Oaxaca, has it colored very much 
as in true L. amethystinus. Before the geographic variations in this species and the 
character of relationship between L. amethystinus and the two local Guerrero forms 
(L. margaritz and L. pringlei) can be satisfactorily understood, a much larger num- 
ber of specimens must be carefully compared. 
b Two specimens, one of them (from San Cristébal, Chiapas) not typical.
