The species on which I propose to base this new genus was 

 placed by Brabourne and Chubb (B. S. Amer. i. p. 250) in the 

 genus DecongcJiura Cherrie. I find, however, that it differs from 

 the typ« of that genus in having twelve tail-feathers instead of 

 ten. The lull is somewhat long and slender, the exposed culmen 

 about equal in length to that of the tarsus. The wing is rounded, 

 the third, fourth, and fifth primaries longest and subequal, the 

 second is intermediate in length between tlie fifth and sixth. 

 The tail is rounded and graduated, and exceeds the length of 

 winf£. (Coloration: male and female similar.
