On the basis of observations by the space telescope Glazar at 1640 Å the distribution of early (O-B-A) type stars and absorption matter in the directions of 20 known OB associations have been investigated. Forty-four stellar groups were found in these directions. The dust matter is distributed within these groups quite non-uniformly and patchy. It is absent in the space between these groups. It has been shown that 93 stars have dense circumstellar dust envelopes and half of them are sources of IR-radiation (IRAS observations). Dust clouds exist in the directions of Per OB1, Aur OB1 and Car OB1 at distances of 460, 1000, 1000 pc, respectively. Twenty new stellar groups of OB types were found.
