Type. 

 Eucometis, Scl. P. Z. S. 1856, p. 117 E. penicillata. 



Eucometis consists of four representative species, and a single 

 divergent form. They range from Southern Mexico southwards to 

 Bolivia. The structure is intermediate between P/jramja and Tachy- 

 phonus ; it is weaker than in Pyranga, and the coloration is generally 

 duller. The sexes are similar. The short nuchal crest is a special 

 character, and there is a slight development of rictal setae.
