How can I setup a Material in Cycles for Z-Transparency?

Question

After converting to nodes in order to render using Cycles I've no idea where to enable the z-transparency. I guess the image textures alpha channel needs to be pluged somewhere but I've no idea which node would be suitable.

The question is how could I correctly setup the nodes to have the same effect as when using z-transparency in BI?

enter image description here

The materials original settings for BI are:

Which renders like:

I had no luck with DarenWs suggestion:

Remove the link of Image Texture Color to Transparent BSDF color, and set the transparent color to pure white. (Looks like you figured it out, but for future reference.) — Brigand, Jul 17 '13 at 06:55

Use a Mix shader as the last node before the Material Output. feeding it the hair material (diffuse shader or whatever) in the lower input, a Transparency shader in the upper, and the image texture's alpha into the Mix's "fac" input.

Using a freshly-made PNG with transparency as the image texture, this does not work. I have duplicated these steps twice. I restarted Blender 2.75a and tried it a 3rd time. It does not work. – user16716 Aug 26 '15 at 20:48

@user16716 You could ask a new question and provide some more details (screenshots, a .blend file etc). – PGmath Aug 26 '15 at 21:38
@DarenW, how to make the node connections like this? – Black Feb 22 '18 at 21:48
