I think this is Tibicen canicularis. Can you confirm? Whole bug and close-up follows.

Tibicen linnei
A male specimen - the tip of the abdomen is small. So you are right when you said it departed to sing (females do not sing).

 
Tibicen
These two are close. What features indicate T. linnei?

 
linnei vs. canicularis
The front wing of T. linnei is distinctly angled before the midlength. There are side views of this insect on BugGuide that show this feature better. There is also an intermediate (hybrid?) form, T. robinsoniana (also on BugGuide), which has the wing edge more bowed but the crossvein area near the angled area more basal than in T. canicularis.

 
Linnei
Lovely, Thanks.

T. canicularis
That body length sounds right for T. canicularis. I spent several days keying out close to 50 canicularis specimens here. Overall length ranges from 42 mm being the largest down to 32 mm being the smallest.

I would agree. Would you have a ventral view? It looks to be female in the dorsal view.

 
Cicada
Sorry, No ventral view and the creature now has departed to go sing.
