We have used $19{\mathrm{pb}}^{-1\mathrm{}}$ of data collected with the Collider Detector at Fermilab to search for new particles decaying to dijets. We exclude at 95% confidence level models containing the following new particles: axigluons with mass between 200 and 870 GeV/ $c^2$, excited quarks with mass between 80 and 570 GeV/ $c^2$, and color octet technirhos with mass between 320 and 480 GeV/ $c^2$.
