Ochthceca contains a group of small-sized species, about 19 in 

 number, confined to the higher elevations of the Andes from 

 Venezuela to Bolivia, and having much general resemblance to 

 6ome of the Mniotiltidce, from which, however, they are at once 

 distinguished by their ten complete primaries. The plumage is 

 rather soft and lax ; the habits rather those of the Saxicolte of the 

 Old "World, as they frequent the more open and higher districts of 

 the Andes, perching on the bushes bordering the streams, and 

 feeding on insects. The tarsi are long and slender ; the bill is 

 moderately compressed.
