****************************************************** PR # 43032 Comparison of the RASS with the (PG) survey has allowed the identification of 3 new BL Lacs, previously classified as white dwarfs, bringing to 6 the number of known BL Lacs in the complete optically-selected PG sample. All six objects are bright in the soft X-ray band ($\sim 10^{-11} erg/cm^2/sec$) but 2-10 keV data are lacking. We propose to observe with ASCA the two for which only RASS data are available (PG 1437+398, PG 1246+586), and PG 1424+240 for which the ROSAT data showed significan ******************************************************
