Query: Chemical and Spectrophotometric Evolutionary Models for Emission Line
  Star-forming Galaxies   We present a self-consistent model under a star-bursting scenario for H{\sc
ii} galaxies, combining different codes of chemical evolution, evolutionary
population synthesis and photoionization. The results obtained reproduce
simultaneoulsy the observed abundances, diagnostic diagrams and equivalent
width-colour relations for local H{\sc ii} galaxies.
