The descriptive text that accompanies your listing within the results
pages comes directly from your page itself.
Simply change the text on the page, and the Googlebot will
automatically pick it up the next time it visits your site:
"Site descriptions in Google results are actually quoted from the web
page in question. Google automatically generates different
descriptions based on the search terms used to find the site (these
"snippets" display the search term(s) in the context of the page on
which they appear).
For example, if there is a pet site that deals with cats and dogs, and
someone enters a search for the word 'dog,' the site description on
Google will only talk about 'dogs.' If a person searches Google for
'cats' and the same site is delivered as a result, the description
will be different it will contain references to the word 'cat' as it
appears on the website.
Google does not display a standard description. We look for the search
term specified and show snippets of where those terms appear. This is
a completely automated process and editing is not an option. If you
alter the relevant text on the page itself, Google will pick up those
changes during our next crawl in a few weeks."
Google Information For Webmasters - The description of my site is
wrong in the results.
Hope that helps!
