From the home page:

"The Orthoptera Species File (OSF) is a taxonomic database of the world's orthopteroid insects. It contains full synonymic and taxonomic information for over 25,000 species and genera (all taxa described prior to 1998) of the Tettigonioidea (katydids and haglids),Grylloidea (crickets), Acridomorpha (locusts and grasshoppers: Acridoidea + Eumastacoidea + Trigonopterygoidea + Pneumoroidea + Pamphagoidea), Tetrigoidea (pygmy grasshoppers), and Tridactyloidea (sand crickets), as well as images and sounds for many species. A database for the Gryllacridoidea will become available in the second half of 1999. This site also includes a searchable database of entomologists working on the Orthoptera."

Another update
not so much a change, as a simplification. The last two addresses listed above both currently work, but the simplest URL to use now is orthoptera.speciesfile.org, which works, and eliminates some of the tagged on bits that would otherwise be difficult to remember (some are still needed, but are filled in automatically).

And, yet another update
The "osf2x.orthoptera.org" pages are old and require a log in now for access. The current URL is http://orthoptera.speciesfile.org/HomePage.aspx.

 
Updated
I wonder how long before it changes again.

Here is the latest link

 
Updated link
Thanks for pointing that out.

New URL for OSF?
Apparently the The Orthoptera Species File (OSF) is now at:
http://osf2x.orthoptera.org/osf2.2/OSF2X2Frameset.htm.

Rather strange web site, if you got to www.orthoptera.org, you are redirected to a numeric IP.
