A life-table was constructed under laboratory conditions for a little known Scelionid egg parasitoid Psix striaticeps Dodd on Canthecona furcellata Wolff. The female parasitoid survived for 12 days and oviposited intensively for 3.5 days. The net reproductive rate (Ro) representing the total births was 38.30. The population increased with an infinitesimal rate [rm] of 0.275 and finite rate of 1.32 per female per day. A generation was completed in 13.25 days. Life-table analysis indicated the preponderance of females due to solitary parasitism and a balanced sex ratio due to superparasitism.
