IDispatchEx::DeleteMemberByDispID
HRESULT DeleteMemberByDispID(
    DISPID id
);
Deletes a member by DISPID.

Returns one of the following values:

S_OK Success.
S_FALSE Member exists but cannot be deleted.

id
Member identifier. Use GetDispID or GetNextDispID to obtain the dispatch identifier.

If the member is deleted, the DISPID needs to remain valid for GetNextDispID.
If a member with a given name is deleted and later a member with the same name is recreated, the DISPID should be the same. (Whether member names that differ only by case are the "same" is object-dependent.)
Example
BSTR bstrName;
DISPID dispid;
IDispatch *pdex; 

// Assign to pdex and bstrName
pdex->GetDispID(bstrName, fdexNameCaseSensitive, &dispid);
pdex->DeleteMemberByDispID(dispid);
