28 BANGS CHIRIQUI BIRDS Vol. Ill 



Campylopterus hemileucurus mellitus subsp. nov. 



Thirty-two specimens, both sexes, Boquete and Volcan de 

 Chiriqui, 4000 to 7500 feet, February, March and April. 



Type, from Boquete, southern slope of Volcan de Chiriqui, 4800 feet alti- 

 tude, $ adult, no. 8425, coll. of E. A. and O. Bangs, collected April 10, 1901, 

 by W. W. Brown, Jr. 



Characters. — Similar to true C. hemileucurus of Mexico, but larger ; bill 

 longer ; tail more deeply tipped with white ; adult male with breast and belly 

 uniform violet (in true hemileucurus the belly gradually becomes much bluer 

 than the breast) ; upper parts with more green, less violet, (in true C. hemileu- 

 curus the green is restricted to the upper tail coverts, wing coverts, and a few 

 of the scapulars — -in the new bird the rump is mostly, sometimes wholly, green 

 as well) ; adult female with back and rump wholly green (in true C. hemileu- 

 curus the adult female has a strong coppery tinge to the upper parts, not seen 

 in the new bird) and throat more violet, less blue. 



measurements 2 (in millimeters). 



Remarks. — Through the kindness of Mr. E. W. Nelson of the 

 U. S. Biological Survey I was able, while lately in Washington, to 

 compare our skins with the fine series of true C. hemileucurus that 

 he and Mr. Goldman collected in southern Mexico. The southern 

 bird proved to be a very well-marked race, at once distinguished 

 by its larger size, longer bill and the color differences pointed out 

 above.
