This genus is readily distinguished by the conspicuous red and 

 black plumage of the male birds and the proportionately long 

 tarsi and toes. The bill is compressed and sharply pointed ; its 

 width and depth at the base are about equal, being about two- 

 thirds the length of the exposed culmen. The wing is emar- 

 ginate, the innermost secondaries being elongated and nearly 

 equal in length to the primaries, while the four outer primaries are 

 longest and equal ; the tail is square at the tip and nearly two- 

 thirds the length of the wing. The tarsus is about equal in length
