What I am giving now is not there in HC Verma:
Semi-Elastic Collisions:
The Collision that falls between Perfectly Elastic & In-Elastic
Collisions are called as "Semi Elastic Collisions".
In these collisions part of the total KE is Lost during Collision
i.e K.Energy is not conserved although the total Energy is
Conserved
One more point to be known in this is that the loss of K.E
in such collisions is not sufficient for the bodies to stick
together as in case of "Perfectly In-Elastic Collisions".
Here the principle of Conservation of momentum holds.
Consider two bodies of masses 'm' & 'M' moving with Vel.
U1 and U2 and collide each other.Let their Velocities be
then V1 and V2.
For Semielastic Collision we have:
e = V2 - V1 / U2 - U1
Hope it is useful.
Cheers!!!!!!!!!!!!!! :)

Always available for help !
But Remember Don't hesitate to ask a good Question but
Be damn serious for Questioning a weak one.
