There can exist a class of particles in stellarator fields for which the cancellation of the toroidal drift is incomplete. These localised particles reflected in the gradients of the helical field, can drift through the separatrix of particular stellarators no matter how strong the field; they form a loss region in velocity space. The loss of plasma due to binary collision scattering into this loss region, in the absence of electric fields, is calculated. The possibility of confirming a plasma with reactor parameters in the presence of this loss is examined.
