We show that one of the components of ellipsoidal binaries is typically either a Red Clump or a Red Giant Branch star, which leads to clear separation split of the sequence E at P = 40 d. In its short-period part, we identify two subsequences corresponding to the two types of binary systems (E-2 and E-3), while in the longer-period part the two groups merge forming a single subsequence E-1. We extract a group of 271 ellipsoidal systems with eccentric orbits, from our sample. We present the P-L relation they follow.
