Measurements. — Males (8 from eastern Chiriqui and Veraguas), 

 wing 39.3-40.8 (40.0), tail 26.1-28.5 (27.2) culmen from base 12.6- 

 13.3 (12.9, average of 7) mm.

Resident. Mountains of eastern Chiriqui (Cerro Flores) and 

 Veraguas. 



Little is known of this interesting species. It was described by 

 Salvin from 2 specimens, the male labeled Castillo, which, therefore, 

 is the type locality. The second skin, from Calovevora, does not have 

 the sex marked but is an immature male, as stated by Salvin, and as is 

 shown by a few spots of the reddish purple of the adult on the throat 

 and upper foreneck. I have examined these 2 specimens and also a 

 female, all collected by Arce, in the British Museum. The American 

 Museum of Natural History has 4 males and a female (3 taken 

 by Arce) but partly with incomplete data. One of the males, with- 

 out a catalog number and 1 female are labeled "Costa Rica," and 

 another male is marked "Chiriqui," all unquestionably incorrect. In 

 view of the known range it is believed that all 3 are from Veraguas. 

 Another male marked "Veragua" is assumed to be from the same 

 place. In the Field Museum collection there is 1 male, also labeled 

 "Veragua" on the original label, but marked "Chiriqui" on another 

 that bears the name of the dealer Boucard. These specimens all 

 appear to be from the period prior to 1870 when Arce was collecting 

 in the mountains near Santa Fe, Calovevora, and Castillo. Strangely 

 enough no one has secured the species in that area since. The only 

 recent record is of 2 males and a female, taken on Cerro Flores in 

 eastern Chiriqui by Ludlow Griscom and his party from March 9 to 

 12, 1924. 



Ridgway (U. S. Nat. Mus. Bull. 50, pt. 5, 1911, p. 605) had avail- 

 able only 2 males and a female from the American Museum. He was 

 not certain at the time that the female might not be that of IS", scintilla. 

 Material that I have seen, including this specimen, verifies its 

 identity as ardens. 



From the little known it is probable that the zonal range is similar 

 to that of Selasphorus scintilla.
