Abstract：
An effort to search for Kolar-like events within the data set of the L3+C
experiment is reported. From a total of 0.89×10¹⁰ triggered events there are no reliable two-prong Kolar-like events observed. The corresponding event flux upper limit 7.1×10^－13cm^－2﹒s^－1﹒sr^－1 at 90% confidence level is deduced based on some reasonable assumptions.
