Some doubly excited autoionising states of helium atoms converging on the N=3 He + threshold are calculated by use of a method of complex coordinates. Hylleraas-type wavefunctions are used for L=0 and L=1 resonances with products of Slater-orbital type wavefunctions with expansion lengths up to 319 terms for L>or=2 resonances. States of parities (-1) L and (-1) L+1 and with angular momenta of L
