Two poorly—studied emission—line stars AS 78 (V ~ 11 . m 2, B - V ~ 0 . m 7) and LS II +22°8 (V ~ 11 . m 9, B - V ~ 0 . m 6) were identified with IRAS sources 03549+5602 and 19381+2224 respectively by Dong & Hu (1991) among other sources having very strong infrared excesses, V- > 8m . Only one U BV photometric observation has been published (Haug 1970) for AS 78 which was discovered by Miller & Merrill (1951) as a Be star. A spectral type of B9 I a or B2–5 v was estimated for LS ii +22°8 by Pesch (1963) from the U BV photometry while near—IR data (K = 9 . m 6, Allen 1973) show a very weak excess in this region. Here we present our recent observational results for these stars.
