Hi All, Hi Andrew, Thanks for your timely reply I had considered Tibicen
pruinosa however after checking out the below references the body markings
seemed to be a closer match to Tibicen canicularis.
Tibicen pruinosa (Say 1825) [Lawson, 1920] {Subfamily Tibiceninae -
concealed-timbal cicadas} - Called "Dog Days Cicada" and pictured in Salsbury &
White, 2000, p. 126 - Photos and calling songs available at Cooley et al, 2004
- Photo and life history discussion at Mason, 2004.
Tibicen canicularis (Harris 1841) [Lawson, 1920, listed the synonym T. aurifera
(Say 1825)] {Subfamily Tibiceninae - concealed-timbal cicadas} - Pictured in
Salsbury & White, 2000, p. 125 (as T. aurifera) - Photo at Mason, 2004 (as T.
aurifera). - Referred to as Dog-Day Cicada in North American Checklist of Moore
(2004).
On the web I was able to find two sites listed below that showed photos of
Tibicen canicularis that had body markings that match.

However with that said I had no complete scientific key to work with and
limited range and descriptive information. Your resources are likely greater so
you may be able to come to a more accurate identification.
I will have to send you the photo as a forward with an attachment in a private
email as I have yet to have permission to release the photo publicly. Any
identification you can make will be appreciated.
It is interesting to note that both Tibicen pruinosa & Tibicen canicularis have
the same or very similar common names. Hopefully from the photo you will be
able to make a positive id as it will be interesting to find out the correct
scientific name for this species. - Cheers Clarence
