Apologies to everyone!
It appears that the link to the Simuliid Bulletin Blog site given
in my previous message has become corrupted.
The correct link to go to is: http://simuliid-bulletin.blogspot.ac.uk Then click on the Tab Archives
I also forgot to mention that R.W.Crosskey's complete Simuliid publication list and other works is published at the same location as a supplement to the Bulletin.
