In Atthis the tail, though short, is nearly normal and rounded, the lateral rectrices 

 being of full width and tipped with white. The lateral gular feathers are elongated 

 and wholly glittering rosy red with a slight purple tinge. 



Two closely-allied species inhabit Southern Mexico and Guatemala. They resemble 

 each other in colour, but may be distinguished by the shape of the outermost primary, 

 which in the northern form {A. heloisoe) is attenuated towards the extremity. 



1. Atthis heloisae.

Delattre discovered this species during his sojourn at Jalapa i, where it has since been 

 found by nearly every collector who has visited that district. 



Most of our specimens came from this neighbourhood, but the species ranges far 

 beyond the limits of the State of Vera Cruz, for we have received specimens from the 

 Sierra de San Luis Potosi in Central Mexico, from Tepic near the west coast, and also 

 from the State of Oaxaca. 



Villada says 1° that it is only found in the Valley of Mexico in the months of June 

 and July, seeking its food chiefly from the flowers of Lythrum vulnerarium.
