.143. Cynanthus cyanurus. 



Obtained once, hovering over the flowers of Laplacea speciosa 

 at Canuto. 



. 144. AgL^ACTIS CUPREIPENNIS. 



A common species where it occurs. We met with it on the 

 paramo, above Vetas, and in a little wood below. Altitude 

 9000-10500 feet. We found one nest in a bush on the 

 paramo, containing one white egg. The nest was composed 

 of some spongy substance, apparently of some fungus, and the 

 outside was covered with lichen. 



145. OxYPOGON GUERINI. 



We found this Humming-bird in the same locality as the pre- 

 ceding species ; but its range downwards was not so far, accord- 

 ing to our observation, by 1000 feet. These restless little beings 

 hovered in considerable numbei's over the flowering shrubs 

 which grew in a sheltered valley on the side of the paramo. 

 The crest and emerald gorget are worn by the adult male 

 only. 



• 146. Ramphomicron heteropogon. 

 Frequents the same locality as the two preceding species, and 

 is equally abundant. 



■147. MeTALLURA TYRIANTHINA. 



Not uncommon among the oaks on the road from Bucara- 

 manga to Pamplona, at an altitude of 9000 feet. We also met 

 with it just below Vetas. We often observed it hovering up and 

 down the trunks of the trees ; and it probably finds its food 

 among the lichen. Sometimes I have seen it clinging closely to 

 the trunk, with wings slightly expanded, looking like a large 

 moth. 



148. Adelomyia inornata. 



We shot this bird at Alto, hovering over the yellow blossoms 

 of a Rudgea, sp.?.; and afterwards near Portrerras, where the 

 same flower occurred again. Altitude 5000-7000 feet. 



149. Petasophora cyanotis. 



Frequented the same flower as the preceding species at Alto. 

 It was also common at Canuto. Altitude 5000-6000 feet.
