  It is shown that for some particular value of the cosmological constant
depending on the gauge coupling constant a continuous one-parameter family of
Einstein-Yang-Mills wormholes exists which interpolates between the instanton
and the gravitating meron solutions. In contradistinction with the previously
known solutions the topological charge of these wormholes is not quantized. For
all of them the contribution of gravity to the action exactly cancels that of
the gauge field.
