Two specimens. 



1 am 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 L. 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 hemg rather more pinkish than solferino). A specimen from San Crist6bal, 

 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. Zempoaltepec, in northeastern Oaxaca, has it colored very much 

 as in true L. aynethystinus . Before the geograjihic variations in this species and the 

 character of relationship between L. amethystiiiiis and the two local Guerrero forms 

 (L. margaritse and L. pringlei) can be satisfactorily understood, a much larger num- 

 ber of specimens must be carefully compared. 



ft Two specimens, one of them (from San Crist6bal, Chiapas) not typical.
