Striped Cucumber Beetle - Acalymma vittatum

Originally thought this might be Western Corn Root Worm -- Diabrotica virgifera. Now believe this is Striped Cucumber Beetle, perhaps Acalymma vittatum?

Beetle
Hi Roger, While you're waiting for an expert, can check out pics for a similar sp - Striped Cucumber Beetle.
The longer middle black stripe and different shape of the abdomen may favor this ID. Sandy S

 
Acalymma vittatum
The impressed lines of punctures are the difference to look for to distinguish from Diabrotica. The abdomen is only bigger because this is a female with eggs. The dark colour of the abdomen and broad yellow stripes on the elytra both look good for A. vittatum

 
Striped Cucumber Beetle
I see the two differences you mention and agree.
